Networkcard problems!

[LCF-AT]

Hi guys,

I have a new problem and need some help.

Yesterday my internet wasnt working anymore and I didnt got it working yet.

So since a longer while I use my new  network card without problems and before I did use my OnBoard network / lan.Since yesterday my NCard make some trouble and I cant fix it.Windows does try to recognize my network connection and does end with "unidentified network" and  thats it.Status does show I have not internet access for IP4 and IP6.I tried almost everything but without success. Just sometimes it did work for half hour and then I got again same trouble.

Normaly I do power off my router for a minute and power on again but also this didnt help.I also de / installed the NC drivers.As last step I tried to enter the datas for IP4 config for the card manually (IP / Subnetmask / gateway / DNS ) but also without success.Still got unidentified network.Using ipconfig /release and ipconfig /renew also didnt work.The card itself always keeps flashing with the lights rapidly it I have connect the cable.No idea anymore what the problem could be.Windows tells me there is a not valid IP konfiguration if I press the problem button etc.If I then enter ipconfig in CMD window I get infos about my IP4 /IP6 / subnetmask (all have infos) but the only missing info is at standartgateway = ,,,,nothing.There should be my Router IP of 192.168.0.1 but is nothing.If I try to enter the datas manually (as I told above) I get also no success and it keeps showing me unidentified network but if I now check ipconfig then the standartgateway is there.Totally strange,

After that problems I tried to connect my lan cable with my OnBoard Lan connection and  there everything works and I get my Home Network Icon etc and have access to internet.So I really dont know what the problem could be now with that card and maybe you have some ideas what I could try to get it work again as before too.So I dont think that the card is broken now or something so its still new.I also dont wanna re-install Windows and I dont belive that this would help.Would be nice if you have some ideas / hints what I could try now to get that problem fixed anyhow.

Thank you

Hi again,

ok I tried today again everything but no success.So now I really think that the Network card is broken anyhow.Now idea how this could happen so the card is just a few months old.The card is working so far on windows (seems to be no hardware problem) but I dont get any valid IP configuation with that card.I also installed latest driver and did reset...

netsh winsock reset
netsh int ip reset

....but nothing.I dont get access to my DHCP-Server with that card.Manually entering of addresses etc also dosent work.Uhhhmm!My OnBoard Lan is working without any problem.I just connect cable and 1,2,3 everything is Online.Also if I enter addresses manually for that OnBoard Lan = all works fine.Did anyone had same trouble with any network card in the past?

Reaktek PCI  GBE Family Controller <-- Problem maker
Reaktek PCIe FE  Family Controller <-- OnBoard & working

Seems I have to buy a new PCI card now and hope that the new one not will make same trouble. I am not sure which model I should choose this time.Maybe any TP-Link card or something / no plan.Just looking on amazon around but they dont have much PCI cards.Just need any PCI card with 1 GB (1000 Mbps).

Ok,so if you maybe cant help to fix that problem with my card etc so then you have maybe some hints about any card I should choose this time etc you know.So I am no hardware expert and can just pick any model by random. I also dont wanna choose same model again which had last time problems with the sheet metal.Anyway,so if you have something to tell then just reply.

Thank you

Hi again,

today I tried everything again to get my NC working and  a few minutes ago its working again!!!!=???? What a BS!Three days I did try all out and nothing did help so that I came to the results that my NC is really broken / damage etc and now I get some success.

So I told before that I use 2 NCs one OnBoard (always working if I connect cable) and my NC card which makes that trouble since 3 days.Normaly I have both settings same = getting IPs automatically from DHCP (service is also running ok).With the OnBoard card all is working fine and I get all infos to see via ipconfig but if I connect same cable to my NCard it does fail to recognize my network = IP config not valid message at the end.If I use ipconfig for that card then some infos are missing like my Standardgateway (Router IP).If I did enter the IP4 datas manually then it also didnt work (for OnBoard it does work) whats also strange.Now I did set IP4 again to auto mode and checked ipconfig again and wrote down the datas and have seen that I got a strange IP address starting with 169...

   IPv4-Adresse (Auto. Konfiguration): 169.xxx.xxx.xxx
   Subnetzmaske  . . . . . . . . . . : 255.255.0.0
   Standardgateway . . . . . . . . . :  <--- nothing

...and this IP isnt in the range of my Routers IP of 192.168.0.1.Normaly it should also start with 192.Now I just connected to OnBoard again and did enter the IP4 I got for my NCard...

169.xxx.xxx.xxx
255.255.0.0
192.168.0.1
--------------
192.168.0.1

....and first I get a warning info about...

Warning - The default gateway is not on the network segment (subnet) defined 
by the IP address and subnet mask. Should this configuration be saved?

...I did press yes to save and tried it.In my ipconfig I get all manually entered infos to see but still no network access.Using ping command works with the addresses.Everything almost very strange.I dont why I get such a strange IP address and also no Standardgateway address in automode.Seems that the DHCP makes any trouble the whole time just with my NCard only.

My OnBoard IP4 settings I did already set to manually yesterday with same address of Standardgateway + X at the end and now I did same for NCard too with +X+X at the end.OnBoard works / NCard still not.Now both using static IP4 settings and no automode anymore.So all in all I wanted to give up now to keep playing around to get it working anyhow and I thought just one more try and did connect cable back to NCard (windows tried to identify NC) and at same time I did remove lan cable from my Router and did connect it back to other port of router (it has 4 ports) and 1,2,3 the network is working now and I have acccess to my router and internet. Such a BS!Three days of working and playing around and now that.With my last try I got it working  now.

So it really seems that my DHCP automode has any issues to give wrong IP to me and also no Standardgateway address.I dont know from where it has / gets this IP range which is wrong and also not working of course.I also dont know how to fix that so that everything works right again in automode for that card.Only working solution for me is now to set IP4 config data manually and unplug & plug the cable from router = success.Of course I am not sure whether this method is always working (will see if it happens again then I try this again too) or not.Before I always tried to power off / power on my router for a minute but there I also had the IP4 settings auto config mode enabled.Now I need to find out why the DHCP doesnt work correctly and how to fix that.Maybe it would work now to use ipconfig / release & renew to fix that (before I couldnt use that commands without a working connection like I have now again).So if anyone has some hints / infos etc about that or my strange DHCP issues and my actually working solution then just reply here.

PS: So it seems I dont need to buy any new NCard (yet).

Hi again,

ok its again not working.After my last post it was working for some hours and then no more,just so again.Also couldnt get any connection anymore with that NC.After that I did reset my router and got connection again but also not very long.No idea anymore what the problem is (just think that the card must be the problem / broken anyhow).My OnBoard lan is still working but I also see that sometimes the connection to internet is away for some seconds!?I did now increase the leasing time of DHCP for ip4.Maybe it will help so before it was set to one hour and I changed this to one day.

I also tried before to start windows in safe mode with network drivers etc but there I also got no connection with that NC.Also changed the PCI slot = same trouble.Now I have enough of playing around what that stuff.

If you are using Windows 10 and have updates turned on, the recent updates they have pushed caused some drivers to update to invalid versions for things such as video cards, wifi cards, etc. Try rolling back the driver if you have the option to.

[LCF-AT]

Hi,

I use Win 7 and update just manually.

I also see another problem with my internet connection.It seems the connection dosent keep constantly running and I get disconnected for few seconds and get connected again.This happens offten now and see that if my mouse randomly gets the load icon (blue circle for loading something etc).Also I have  seen it during some downloads so they just stop and starting again from 0 in browser.Not sure why I have that problem now too.Maybe the router but I already did reset it too but dosent help. Maybe again some DNS issue.I try to use a fix router ip4 now.Will see whether it works to keep connection running constantly.

greetz

[evlncrn8]

have you checked your power settings ? perhaps its turning itself off from some setting to save power... 

[LCF-AT]

Hi,

do you mean from the card / OnBord itself?There I have 3 energy options to enable / disable.The first both options I have enabled and the third (Magic Packet etc) I have disabled.I always have that so also before where all was working.The other card options I have original except 2 options (I did change speed to 100Mbits full duplex & the other speed to slow down = dont slow down).All in all same as always.Now I tried this steps again...

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

In my router settings are no power / energy options.I also did scan my HDD for any bad stuff but nothing found.Maybe my ISP itself is the problem at the moment.I am not sure of course.

greetz

[PermaNull]

They're referring to windows power options, some of the power saving options in windows have things which disable networking.

 

I've tried fully reading through all of what you've said, it sounds like it's either a physical problem with the network card(maybe even motherboard) or driver issue... considering even when setting the IP statically (assuming you also tried physically disconnecting the cable and reconnecting it after setting these options)... there's a chance it could also be your router. I have a suggestion if you're willing to attempt it, you should try booting a Linux live CD and see if you can establish networking over the card which does not work without any problems, if it does you would know it wasn't hardware based and it was related to drivers/OS settings.

If you get into the Linux Live CD and your networking is still messed up I would believe it's either incompatibility with the router. Bad Network card, or something else going on.. Have you tried other ports on the router as well?

And you're not doing any crazy double natting or anything right? (Modem)->(Router) without having Modem bridged.

Another idea, double check that nothing has set a proxy on your system via Internet Explorer's options. Sometimes malicious stuff will override your default proxy settings, or a plugin for a browser (TOR etc.) can cause it. Or even tools like Fiddler will override the proxy settings of the system to filter information.

Would that be card specific though? I don't believe it'd cause the DHCP issues either.

Hi guys,

thanks for your feedback so far.Today I tried again some things and did first power of my router for 30 minutes and tried again to get my NCard working (not my OnBorad) but again without success.I dont get any connection to my router also not if I use static router IP / gateway and a local IP & subnet.The icon in task always loading and trying to indetify the network.Nothing helps anymore with that card.If I plug cable into my OnBoard card then it gets connection very quick.For both cards I have almost same settings in the card options itself so there are not much diffrents.Cards are almost same model...

Reaktek PCI  GBE Family Controller <-- Problem maker
Reaktek PCIe FE  Family Controller <-- OnBoard & working

...I also dont use any special settings just my router / cable (cat 6) & computer and thats all.Yes I also tried other router ports before but its also not really working.I also use latest NC drivers too.In safe mode the NCard gets also no connection to router.

The lan settings in IE options are set to auto (not using proxy / VPN etc).Everything looks correct so far.I also use Fiddler sometimes but there I need to set browser proxy manually to localhost / port if I use it and set it back if I am finished.The latest app I did installed was OpenSSL and few days after I got that NCard problems but I dont think that this is the problem or?

Maybe the GBE card is damage anyhow also if I dont understand why.OnBoard card is working but has that disconnect / connect issues also if I wrote this reply it did happend again anyway whether I use static IP datas or auto.

Do you guys know any Network checking tools etc which could sniff the problems etc?Router / card or ISP etc.Thats really sucks and I dont know what the problem is.

PS: About new NCard.The only card I find are these from Reaktek I got already.Other PCI cards I do find are old models (also dont see any Win 7 support infos).Not sure which one (Giga rate) I should try next or whether the older models do work with Win 7 too.I only have 2 PCI slots I could use.

I still suggest if possible trying this with a Live CD of Linux and seeing if you have any problems. Can you give the exact model of this Realtek PCI GBE Family Controller? Have you tried manually updating drivers?

Have you tried a different Ethernet cable? (Cat5)
Have you tried another port on the router?

I don't believe any settings should affect it, (OpenSSL; Proxies; etc.) due to the fact it's DHCP related and a lot of these things don't take place till after DHCP is completed.

Also I'm curious if you've tried normal network troubleshooting options in windows?

 

The Diagnose button I mean.



Also to clarify:

 IPv4-Adresse (Auto. Konfiguration): 169.xxx.xxx.xxx
   Subnetzmaske  . . . . . . . . . . : 255.255.0.0
   Standardgateway . . . . . . . . . :  <--- nothing

 

Standard Gateway = 192.168.0.1 (The IP of your Router)

Subnet Mask should be 255.255.255.0

And IPv4 Address you would assign something like 192.168.0.100 (Or some other number not taken within the 192.168.0.x range.

 

I see previously you said you saved it with 169.xxx.xxx.xxx this won't work, this is the IP address windows assigns when DHCP fails.

For DNS servers you would write either 192.168.0.1 (for the first) and leave second blank or some external DNS like google (8.8.8.8.) (8.8.4.4)

It's a cheap network card. They break down occasionally. Throw it out and get a new one. It's ten euros anyway.

And that's my Christmas haiku.

[LCF-AT]

Hi again,

so I tried this already to enter IP4 datas manually but also without success for that GBE card.Still no connection to router.If I do same with OnBoard = working.Thats the diffrent.Sometimes before it did work durring making tests as I told above already where I thought I did fixed the problem but then after some hours of working it didnt work anymore after.Seems that this card just works sometimes randomly only.OnBorad works always but it has this few seconds disconnect / connect issues what also sucks.

Where to see the model of Realtek PCI GBE Family Controller?Just see that name only.Yes I also tried to use diffrent drivers too.Latest driver I do use now 3/Okt/2017 driver-version 7.114.1003.2017.I am just using my cat6 cable now and also tried diffrent router ports too.Also tried using troubleshooting of windows and it did work rarly 2 or 3 times only before but mostly I get invalid IP configuration error at the end if I have enabled auto mode for IP4 = 169.xxx MS reserved IP.

Yes I know its a cheap network card kao,just wanna know whether its a good idea to buy the same model another time or better any other one .Also the selection of NCards for PCI slots are very limited.Not sure whether makes sense to choose other models if they using same chip.

greetz

[atom0s]

If you are setting static IP's you have to be sure they are also assigned/set on the router end as well otherwise you are going to land up either being rejected from the network, have IP collisions, etc. 169.x.x.x is the default IP Microsoft assigns to a "disconnected" network device. 

Have you tried just directly connecting to the modem itself and seeing if it still has issues? That can help rule out if the issue is with the router or the nic itself.

[LCF-AT]

Hi again,

my router gateway is 192.168.0.1 and I am using forwarded IP 192.168.0.2 or higher (last value).For my OnBoard card they are working too if I enter static IPs.What do you mean with directly to modem itself?

I did order some new NCards now (one is same model) I could test them next week.Will see what it brings and check whether my card is really damage or not if the other same model does work then.Anyway,just hope that one of the new cards will work as it should and longer than my other one.

greetz

[cachito]

This is what I would do.

Set network card with this fixed info:

IP: 192.168.0.240 (something high, between 200 and 254 so you don't get overlaps with other devices)

Netmask: 255.255.255.0

Gateway: 192.168.0.1 (router)

DNS1: 8.8.8.8 (google)

DNS2: 208.67.220.220 (Opendns)

Next you should test pinging the router and see if it responds. If it responds then card and cable and router port are working and you should check router config.

If it doesn't work then you should check the other stuff, if you say you tried another cable and port then it is the card the one with the problem.

 

You already tried the netsh commands so only thing left is to try deleting and reinstalling the card OR going back to a previous driver (if it has any)

Uninstall device, then click on "search new devices"

Revert driver

If none of this stuff works, then either the card is broken or windows is...

Once I had a problem with an HDD with a broken sector where the inf driver was stored, but that was just a weird case

Rather than having the router plugged in, plug your computer directly into the modem you use to connect to the internet with. (Unless the modem/router are bundled together.)

[LCF-AT]

Hi,

the steps I did tried already before using static addresses but without success.Also using google as DNS did also not help.Driver rollback also not.

Today I tried again one more time to connect the cable on the NCard but again nothing.After that I did connect cable back to my OnBoard NC and got internet but this time it was a little strange so I got internet (can browse normaly) but I couldnt access my router site anymore (endless loading).But the ping to router was working!=?After restart of PC it was working again.

So as I said I just have that router box (with firewall and other zip & zap) and no modem between etc.

[LCF-AT]

Hi guys,

ok I have the new cards now.I tried one first and got some trouble.

Model: TP-LINK TG-3269

First issue is that windows used the Reaktek PCI GBE driver for this new card and I had to change that manually to give it the real card driver (TP-LINK Gigabit PCI Network Adapter) and this driver is not signed (but its from CD).This driver works too.So I got internet and connection to my router with that new card and all seems to be ok on first view.As next I did make some speedtests and got a speed of 60 +/- Mbps which is just the half.Next I did a network check using analysing tool from router and there I get one error about my network cable.Check connection of cable.So the cable cant be the problem so its also new (just few months old) and has cat 6.In taskmanager / or details box I also just see a transfer rate of 100 Mbit/s and not 1000 Mbit/s (or 1 GB) etc.So what could be the problem now that I only get 100 and not 1000?If I press diagnosis button on detail box of connection then at the end I get a windows message...

The computer is configured correctly, but the device or resource (dns-server) does not respond.

....only.Thats strange so internet is working.Has anyone a idea how to get 1000 Mbit/s?

Is there also a way to reset / delete all connections from my PC so that it creates a fesh one etc?

Next I will try the second card to see whether I get 1000 or again just 100.I dont think that the cable is broken or something so its laying around.Maybe you have some hints what I could try next.

Thank you

[LCF-AT]

Hi another time,

ok now I did test my second new card which is same model as my trouble card before (Reaktek PCI GBE Family Controller) and surpise surprise I get the stupid same trouble with that new card too!!!!What a FBS!So whats the problem now with that cards?I really have no clue anymore why its just not working anymore on my computer.The LEDs just blinking like a flipper right after I did power on my PC.Maybe its any mainboard issue?I did reset the settings to default and installed all mainboard drivers from CD of mainboard but also no change with that card.Uhhhhmmmm!In that case I hadnt buy a new card if I get same issues = my old card is not damage.Problem must be anything else but how to find out?

The other TP-LINK card is working straight without problems but only gives me that 100 Mbit/s instead of 1 GB and for that I also found not the problem yet. Men men men men men you!

PS: On internet I found some infos about CMOS / battery to get them out for few minutes and get them back (should fix that 100 Mbit/s problem to get 1 GB back) but didnt tried it yet.I think there was also something with jumper doing or so.Uhhm!So if anyone on the whole wide T4Y planet has any or just any tiny little and small idea what I could try to fix the problem/s then please just reply something.So I am out of ideas now / game over / holly krap limit reached / end of working day and whatever I could tell me.

By the way,yes I also testet again all PCI slots / router ports / router resets / set card to gigia fullduplex etc.

Thanks again so far and I hope that some people could post something later.

First, if 100mbit work just fine and 1000mbit won't, it's most likely the cable. Check that first.

Second, since you're buying shit cards from shit manufacturers, their driver support is.. yes, shit. Find out what exact chip this card is using and download drivers directly from chip manufacturer.

If my google-fu serves me right, your TPLink card is based on Realtek RTL8169, so this should get you the proper drivers: http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PFid=4&Level=5&Conn=4&ProdID=10&DownTypeID=3&GetDown=false&Downloads=true

For your other card, you didn't give enough info.

Third and probably most important, Google how to remove old and buggy drivers from your copy of Windows to ensure that only the proper one is installed and loaded.

[Kurapica]

I think we should send LCF-AT a gift "Network card" to end this suffering

good cards are cheap now, so maybe you find a reliable model next time.

 

[evlncrn8]

could be the motherboard too though, in which case a new card wouldnt help..

i think the best course of action would be to use a linux live cd, boot from it and see how the network behaves...
