I have had a Linksys E2000 router for a few years. I have one wired connection and several wireless connections in my house. Up until now I haven't had any problems and I haven't changed any settings or added any other computers. The router stops allowing connections between computers on the LAN. If I unplug the router and then replug it in, the connection works again for a little while before stopping at some point (usually within a day). So, it is definitely an issue with the router as far as I can tell. Connections to the internet for all of the devices are never affected.
All of the computers on my network have static IP addresses. I can't connect to other computers for file sharing, viewing the web server on my printer, etc. Trying to ping the other computers also does not work. Does anyone have any suggestions for what I can try to fix this? I'm really not sure where to even start. Thanks in advance!
