We are spending the winter in our RV and occasionally move from one RV park to another. Normally when you register at the park, they give you the wireless password if there is one. We have been in three different RV parks this week and two of them would not let Ubuntu sign on. On these occasions my Windows 7 (dual boot with Ubuntu) and my phone were both able to get on the wireless system so I know I have the correct password. I have played with different settings for security with no luck. The setting for my phone is WEP (which is working). Any ideas for what to check next? I don't want to be stuck with Win 7 for the next month.
