Re: USB adapters with chip antenna


Maybe Jeff can comment on this observation.
The Network Everywhere NWU11B seems to be very similar to the Linksys
WUSB11 with a diffirent color case.
They can sometimes be found on clear outs very inexpensively.
This model can be tricky to set up non XP if you allow the computer to
reboot after the software install ( before inserting USB connection).
Funny part is that Windows itself often tells you to reboot before
attaching the USB connection.
After reading the manual you discover the working procedure is to
attach the cable after software install with no reboot.
Hence the clearouts.
