Can't always get what you want, I guess
Sounds like a radio interference issue, which might be solved by disconnecting the power supply to the central radio thingy for 20 seconds, it might select a better channel to interact on. Another thing that might help (if you have an antenna coming out the back of the PC): is adding an aluminum shield, to whichever side has more houses (other wifi stuffs) on it. There's a small program called Homedale that can show you how bad the radio landscape is, by listing all the gadgets on wifi... you'd be surprised!

Is your PC wired or wireless? Any time I have network issues, I shut it all down and reboot, including the incoming powered stuff... disconnecting from the PC, the wireless thingy, back to the powered modem; then power the stuff back on, from where it comes into the house, to where it sits in front me. Flushes crappy error checking data. Hope it works!

I was self-promoting myself and now I have people asking me about my PC ok then XD
It's wireless but I think it's the area. My tablet and phone work fine but I'm literally connecting my computer constantly. I would say it's because it's running low on memory but I still have 3/4 of a terabyte left. I've gotten used to it because I don't utilize my PC except for making audio and making news posts which are usually random like this one.
