I am dual booting 9.04 and 10.04. With 9.04, I get my wireless connection using a Dynamode 802.11n usb adaptor as the onboard Realtek RTL8187b doesn't work under 9.04. I'm quite happy using the adaptor as my router is a 11n as well.

After installing 10.04, I was able to get a wireless connection using the Realtek, but no connection with the Dynamode. The problem is that the Realtek wireless connection either drops out after a few minutes or is slower than a dialup or doesn't connect at all.

Can anybody give me some advice on getting the Realtek connection working correctly as I feel that an internet connection may just be useful!!
