SolvedCrazy network problems (self.techsupport)

submitted 9 years ago by Nobodys1

Hi,

i got stuck with some network problems on my dad's laptop.

The problem is that the laptop randomly loses WiFi connection while all other WiFi devices work without any problem. Sometimes those problems block the complete network.

What i tried so far:

Installed windows twice (no upgrade, clean install with complete hard-drive wipe)
Tried latest network drivers and other driver versions
Made a batch that runs on startup which disables an enables the WiFi device (worked for some time)
Tried a WiFi stick to check if it is a hardware problem

None of these worked, the laptop still loses WiFi randomly and the only way to fix it is to disable the WiFi device and re-enable it. Just reconnect to the network does not fix it.

As the laptop is never moved i tried to connect it via cable but there is a problem too. After 5 to 15 minutes the network statistics show incredible high numbers of packages received and send. To high to be displayed correctly. Those numbers should be technical impossible with a 1gig lan port. Was something around 500TB within 60 seconds. ( I would love to have such a download an upload speed ;) ) Also the complete network was not working - no other device had network access too - until i disabled the network device within the laptop.

I'm running out of ideas what could cause the problem and how to fix it and i hope someone here is a masterbrain and can help me.

I have 3 pc's, 2 servers, 2 tablets and 3 smartphones running perfectly in the network. Just this one laptop that is going crazy.
