Is there something I should do to my networking configuration in Ubuntu to better the performance of my wireless connection? I'm on a netbook dual-booting Windows 7 and Ubuntu 9.10. I pick up much stronger wifi signal when in Windows than Ubuntu. As soon as I boot Ubuntu, it will connect to the network with a stronger signal, and then loses signal very quickly. After it dies, I can't reconnect. I've tested this on a couple of different networks with the same outcome.
You can try upgrading to 10.04 since it comes with a newer kernel which means newer drivers, better wifi (maybe). Or you can use a newer kernel from a PPA (Personal Package Archive). (Anyway, this happens usually quite often, in Windows you get a better signal due to the better driver.)
