problems with airport connections after upgrade

macbook pro OS 10.5.3
Internet access wireless using DSL with airport extreme

I updated parallels in a MacBook pro yesterday. Following installation, it asked questions about ths network and its setup. Apparently I did something wrong because parallels reconfigured the base station & i cannot access the Internet and my MBP is not recognizing the base station. (it doesnt show up in the airport utilitiy) I tried apple support and also paid a visit to the genius bar today with no luck.

Any ideas about getting the computer back to normal? The computer did access the Internet and email at the apple store so the problem is in the connection to airport.

Additionally the DSL is working and can connect to Internet on a pc using a cable but it did not work on the MBP.

Any ideas are welcome. This is frustrating.
Thank you

ip problems?

does parallels alter ip addresses and is it possible that it interfered with the DSL connectivity?

 

Please list VM pvs file
and ifconfig -a from Mac OS

also System preferences -Network -screenshots for every location

can't do

can't post screen shots because I don't have internet. All messages sent via iPhone.

It looks as if our DSL was not working. It will now work with the pc but both MBPro's cannot connect either through ethernet or wireless. so strange.

 

please post from IE from within Windows
