I've been trying to help my father out with WiFi issues with his Dell Studio 1749. He has a Siemens SE587 ADSL modem/router which supports Mixed, B_only, G_only WiFi modes. The laptop has a Dell wireless 1397 WLAN mini-card which supports Loose 11h, Loose 11h+d, and Strict 11h WiFi modes. No matter what combination of modes I configure in the router and the laptop the wireless connection on the laptop only ever comes up as 1MBps or 2MBps (full strength signal, laptop right next to router). By contrast my ageing Dell Vostro 1700 always connects to the same router at 54MBps.
So I'm guessing that there is some incompabitility between the router and the laptop. We're happy to replace the router, especially as recently the ADSL side of it appears to have gone a bit flaky. I've scoured the 'net and cannot find any router which claims to support 802.11h, so (a) what should I buy and (b) how can I be sure it will work at a sensible speed with this laptop given that the one we currently have won't?
Thanks,
Mike
