Network Problems

Archived from groups: microsoft.public.windowsxp.hardware (More info?)

Hi

I have a 54g Belkin PCI Network card that connects to a Linksys 54g Wireless
Router/ADSL Gateway. Just noticed that the connection is at 11Mbps. The
router is set to Mixed (ie 802.11g and b) but when I select 802.11g only my
PC drops the connection.

Very frustrating as I'm trying to transfer my music collection

I'm running XP with Service Pack 2 and have updated the Router firmware

Thanks

Steve

So that means I'll never get more than 11Mbps does it? The fact that
connection drops when I select 802.11g suggested to me that it was a
different problem
