Hi guys,
I am also having trouble with my Dell 1450 USB Wireless adaptor.
My symptoms are exactly as beanso has been describing:
The connection seems good, but almost exactly every minute I get 3-5 seconds where no data can transfer.
My PC is a Dell Dimension 9100, and came pre-installed with Windows XP SP2 which was configured to use Dell's USB 2.0 Wireless LAN utility rather than WZC. I am using a D-Link DI-634M access point, configured with WPA-PSK TKIP.
My signal seems to be very good at all times (about -60dB), and the connection is stable at 54Mbps.
I have since tried uninstalling Dell's USB wireless LAN utility and turning on WZC. I have also tried turning off all encryption, and different channels on the access point. I have also installed the latest drivers from Dell, and upgraded the firmware on the access point.
If I ping the access point, I get average latencies of around 9ms, but 3% packet loss. This is consistent regardless of encryption settings and channel selection.
When I use my laptop in exactly the same position as the Dell 1450 USB wireless adaptor, I get no connectivity problems at all.
At the moment, I suspect that the problem is due to the Dell 1450 USB wireless adaptor. It seems unlikely that mine and beanso's would fail in the same way, so I suspect faulty drivers are at play. I will phone Dell when I get home from work to try and find a solution.
I will keep you posted.
Regards,
Swenhar
