I don't have an answer but I am intrigued.

Does the wlan connection go down from actual "radio" interference from the
scanner or because of some USB-NIC conflict.  In other words, can the scanner
operate on a different computer and not break the wlan connection on the
original?  Or, if you operate the scanner, attached to a different computer
but still next to the wlan connect one, does the wlan connection go down?  If
that is true, the scanner is spitting out 2.4GHz noise to the air, messing up
the wlan connection.  I am not sure how you could fix that!
