Re: How To Tell NetworkManager There's a Wireless Interface To Manage?

Rich,

Two things you can try:

#1 Use an external USB wireless adapter, if that works fine you know its 
a problem with the hardware in some way.
#2 Take out the internal wireless adapter in the Dell and swap it for 
the one in the Sony and vice versa. If the Dell behaves like the Sony 
did, you have a problem with the wireless adapter. Seek a replacement 
one similar to the working one and use that instead. If the Sony still 
plays up, its more likely to be the Ethernet on the Sony that is the 
problem.

Best,

John
