My network starts with a Belkin DB750 wireless router, Then on top of the 4 cell phones, that I don't count, there is one Dell desktop running XP and used as just a media server on the tv, it has a blue-ray player installed and is used to stream Netflix to the tv. Then there are two Dell laptops running 8.1, one Acer running 7, and one that is almost never connected to the network, running Edubuntu for my 9 y/o that has a learning disability, occasionally I will download a new game/program for him, so I don't count this one either. Connected to a USb port on the Belkin I have a 1 tb WD external hdd, used for backups, and the other USB port on the router serves as a print server for a non-networked printer.
Occasionally, and completely randomly one pc will lose connection to one of the other pc's. For example this morning I needed a file from the Acer, however I got an error that the device wasn't found, and another that said the address was wrong. I don't see how it's the address being wrong, first 8.1 does show the Acer in the Network folder, I also have mapped a drive to the Acer that has worked for a month now. At the time I tried to access the Acer I could see the screen, the screensaver was on, but the pc was not asleep, and to troubleshoot I connected to the internet and loaded a page. I was also able to access the Acer from the other Dell, and could access the other Dell from my Dell, and the Acer would connect to my Dell, so I pushed the file over instead of pulling it.
Yesterday I connected to the Acer no problem, but Friday I couldn't connect to the other Dell for about 3 hours, even though during that time I could connect it to my pc. So whatever this is is a one-way problem, that affects all the pc's. For example I could connect to the Acer, but it could not find mine. During the "outage", both pc's will connect to other pc's, and the reverse connection of the originally tried works. I have had some network issues in the past, but usually about 30 minutes troubleshooting, or checking the internet fixed the problem. I have read a bunch of threads about losing connection to other pc's, but none were the exact problem I have, What is so frustrating is the randomness of it. I can access another pc now, but 10 minutes from now, I won't be able to, and then an hour or two after that it starts working again all on it's own. It is not in any one pc, it affects all of them, I don't see how it could be a router issue as when the problem is happening, the other pc's can all connect to each other, and there is only one the affected pc can't connect to it still connects to all the others.
