D-LINK DWL 122G USB problems

USB wireless speed problem

D-LINK mail support have passed me to their toll-free phone number - in America! Not useful for a Uk chap.

I've bought 2 D-LINK DWL 122G USB devices. Both are running on high spec machines.

Even with the devices 7 feet apart in direct line of site, and trying ALL channels, turning off cordless phone bases etc, they won't connect at more than 802.11b, 11Mbps.

My throughput at that frequency is only around .7 Mbps (20 minutes for a 700mb file transfer!).

What the hell am I doing wrong?

The software doesn't allow me to select a transmit speed - it auto-configures itself.

My signal strength varies from 55% to 70%. Surely at 70% that's enough to switch to 11g?

Thumbs up for it sustaining its connection at the low speed though. I transferred 8gb in 4 hours with no hiccups, but I wanna stream video not just MP3!

Netstumbler shows that there aren't any other networks in my locale.

Why do I always feel like giving up on wireless networks?

Maybe they can help you a little more. Sounds like you are doing everything right. One thing you may try is moving the wireless USB interfaces to a powered USB hub. Maybe your computers aren't supplying enough electricity to the devices. Also make sure you're "high spec" computers have USB 2.0.

You SHOULd be able to get G for a pretty good distance. I use my wireless outside / in the basement w/o any trouble.
