CodeExplorer Posted May 19, 2018 Share Posted May 19, 2018 (edited) Why ping doesn't work??? I have two computers: one laptop with Windows 7 SP1 and one PC with Windows XP SP2. I have internet access on all computers. If I connect computers trough routers -> ping (command prompt) doesn't work (time out) while the ping from the router page works ok. If I reinstall on PC with Windows XP SP2 the OS Windows 7 SP1 ping doesn't work neither - so that won't solve my problem! If I connect the two computers with an UTP cable, I make a peer-to-peer network, I set proper IPs: result: the ping works ok. The IP addresses from router page seems to be of all devices with was once connected, and not devices which are currently connected! From what I saw it seems that problems come from the router!

Kurapica Posted May 19, 2018 Share Posted May 19, 2018 Make sure you can send and receive ICMP messages, ping requires that. Link to comment Share on other sites More sharing options...
Extreme Coders Posted May 19, 2018 Share Posted May 19, 2018 Some routers have an AP isolation option to prevent devices from communicating with each other. Disabling this option can solve your problem. https://www.tp-link.com/us/faq-2089.html https://www.linksys.com/us/support-article?articleNum=135098 Link to comment Share on other sites More sharing options...
CodeExplorer Posted May 19, 2018 Author Share Posted May 19, 2018 (edited) I've forget some infos: Quote Device Information Software Version RP2624 Device Model AN5506-02-FG I tend to think that my router is a piece of crap! @Extreme Coders: My router doesn't have that option! I've found a strange thing: Settings » LAN » DHCP Server Option60 with two options Disabled or Server Edited May 19, 2018 by CodeExplorer Link to comment Share on other sites More sharing options...
Extreme Coders Posted May 19, 2018 Share Posted May 19, 2018 DHCP is for assigning IPs to devices when they connect to the router. Looks like this is a common problem with that brand of router. Check this gist: https://gist.github.com/kbeflo/de3b1610b1879f8e92966ba106f83f97 Apparently, there seems to be a client isolation feature buts its hidden in the main ui. Have to edit the html in order to display it. No idea whether it'll work or not. Link to comment Share on other sites More sharing options...
CodeExplorer Posted May 19, 2018 Author Share Posted May 19, 2018 Many thanks to all who helped me! Now I'm sure that Isolation is the problem. A firmware upgrade of router may be a solution, but I can't find any firmware for that device! I would even downgrade my router firmware if that would solve my problem!
