Plug an ethernet cable into this computer ????

[Hitman4hire43]

Hello guys , i have a problem with my desktop pc and I really can't find a solution to it. Recently , I started to get dc and the only way of making it work again was to turn off my modem, wait 10 seconds and then restart the pc. Recently i was downloading a game from steam and after 3/25 gb it dc again. Troubleshooter reported 2 problems. The first with an red x stating that an ethernet cable is not properly plugged in or it might be broken (my cable is new and it works fine) and one with a yellow triangle stating that local area connection doesn't have a valid ip configuration. Ok so I gave up and did 2 things: first i checked my hardware. They said it works perfectly . Then I unplugged my modem thinking that this was the problem. I plugged the cable directly into my pc and had to use dial-up connection. Ok , i entered the user and pass , connected and after a few days of perfect connection i've decided to resume the download. After downloading another gb it crashed again . So out of frustration i took my pc to my friend and used his connection for the download . It worked perfectly . Now i am back home and guess what? After trying to download a large file it crashed again and now it won't even connect back. i. Have never seen something like this , it just collapses if it uses up more that 3-4 mb/s . Now the troubleshooter says the swme about the cable and the ip . My settings are to obtain an automatic ip ... My driver is fine , my cable is fine , wireless on laptop works , so it's not the provider ... My brain is bleeding .Any ideas About this?

I would first try power cycling both the modem and router. unplug both and wait about a minute; then plug the modem back in first; and let that boot; then plug the router back in and let it boot. Also, check for a firmware upgrade for your router. If there is one; download and install it. Once that is done.I would go into the device manager in the control panel and uninstall any either net related connections and or devices. Any onboard network cards; uninstall them and let reboot and let windows hopefully detect it and reinstall the proper drivers, etc for it. Try any or all of these things and see if they help ya out any.
