Network Issues (Limited Connectivity)

I'm running Vista Home Premium SP2 (all the latest updates and drivers) x64 on a 2.2ghz amd dual core with 4 gb RAM. Recently I had a power surge hit my home and kill my built-in ethernet adapter (I have everything plugged into surge protectors ... EXCEPT the cable that runs to my cable modem, which was also fried). To my knowledge the nic in my laptop is solder to the motherboard, so replacing it would very costly. I decided to purchase an ASIX AX88772 Fast USB 2.0 to Ethernet Adapter. It works perfectly for 24-48 hours (my laptop is running 24/7). However, this is where the problem starts...

Seemingly randomly I will see that my network icon is now showing limited connectivity (even though my usb adapter is still flashing send/rec and my cable modem still has the PC light on ... however the cable modem is no longer flashing the send/rec leds). When I try to repair the connection it always fails. If I try to disable then enable the connection explorer.exe (process that manages network and sharing center) crashes (not responding and has to be killed and then rerun) even if I try this on a different connection (ie my old built in nic, or my wifi). Also, once this happens I am no longer able to connect to ANY networks (via wifi), windows will not locate ANY available wifi networks to connect to (even though there are over 8 in my area). Another baffling symptom is that if I try to shut down/restart/Log off it sits at the restart/shut down/log off screen and never actually completes the appropriate action. The only fix is to manually shut down my laptop, then turn it back on! After that everything works perfectly.

I have somewhat of an IT background, however this issue just baffles me. I've tried searching the internet, but I've not been able to find anyone with even similar problems.

Any comments, questions, help, etc are VERY appreciated. Thanks!

Sure, I'll do that the next time it freezes up.

Hope it works, thanks!

PS - Just looking over the batch file ... it seems it has a command that restarts the pc ... this already fixes all my issues. I guess if my laptop actually restarts properly that may be a sign it worked. Will report back with the ipconfig image and further developments the next time it happens.

Ok Just happened again ...

I followed the steps provided to the best of my ability. I took the pics of my ipconfig /all -





(Sorry needed 2 pics, didn't all fit on my screen at once)

I then ran the batch file that was attached to the page. However it failed to get past the renew command, so I then opened up another command prompt (with admin rights again) and copy/pasted the other commands in. They all worked except the last one, shut down. Again my laptop refused to reboot (waited like 10 min, got past logging off but couldn't get past shut down). I had to manually power down, which then fixed all my problems. Just to be safe, I ran the batch file again (I didn't put in the the command to delete itself when I was copy/paste'ing) and it worked perfectly. I doubt those basic commands will fix my issue, but we shall see, as you can see from the 2 pics my connection will only last about 24-48 hours before it will strike again (I really hope not!).

PS - I blanked out my IP4 and IP6 numbers, because I do not use a router and do not feel safe broadcasting out my IP over the net.
