Yes those Power Options come in handy for turning off those power saving features. They do tend to cause many problems. Updating eithernet drivers usually saves the day in most cases. Give it some time to make sure it's working correctly and report back in if you can.
I think the problem is getting better although it still re-appear,
but the good thing is I don't have to restart my router anymore... when the network is unidentified, i enabled my wireless, connect my desktop to the router trough wireless and the unidentified network from Ethernet (cable) connection fix itself than I disabled my wireless again (since i prefer connection with cable)
will it be my Ethernet card? but I'm pretty sure it worked properly a week ago when i was still using XP
How about writing a script to automate that process for you...lol j/k.
It does look like you have an issue with the ethernet card, as i assume you have used the correct cable type. You mentioned it's a MAC laptop. It could be that the router isn't compatible with MAC type adapters. Your wireless adapter has to be compatible cos it's working lol....
