though I did have an issue with my iPhone (both the original and 3GS) and Ubuntu netbook not always wanting to talk to it that took a long time to figure out. Until I figured out the solution, I just used cellular for internet and an ethernet cable for the netbook.

After much searching, I found mention to try changing Wireless Security from WPA/WPA2 Personal to just WPA2 Personal, and that fixed it; however, now my PSP won't talk to it. I don't use the PSP on the internet, so it's not been a problem.
