hey men8ifr,
I can see you have another thread open for your CD writer issues, so we will stick with your network problems for this thread.
I wouldn't have thought a failing motherboard would have caused slow network connection on both USB and Ethernet connections, but anything over 30 seconds to obtain an IP address isn't good. However, in reality, slow network connectivity could be caused by anything, anywhere between your router, PC hardware or most likely software.
If you receive any related error messages, these will be very handy. Slow connectivity is very often impossible to diagnose. Otherwise it's a case of ruling out one possibility at a time, starting with PCHF Prework on my signature.
