Motherboard Ethernet Port Issues Until Restart

[thebig5gun]

One of my PC's does not connect to the Internet in the morning when booting up for the first time. I have to restart the computer everytime in order for it to start recognizing the signal.

Window's says it's a driver/hardware related issue so I reinstalled LAN drivers and nothing. Also checked router, modem, cables, and those are good. No other 5 machine's wireless or wired are reporting issues.

So at this point I'm thinking it might be a faulty Ethernet port on the motherboard itself. Any ideas or suggestions on how to fix?

Try cleaning your UTP/LAN cable.

for easy and free maintenance, use a pin or a needle lightly scratch the LAN cable's gold contacts.

Alright I'll try that out, thank's for the suggestion.
