So where I live most of the time, the 802.11 access points that are installed utilize an anti-rogue AP mechanism that not only blocks other APs from using the same SSIDs they are advertising, but to also prevent other 2.4GHz networks from being created and used as a way to enforce their ban on setting up private WLANs.
So I recently acquired a Nokia N900 and wanted to SSH into it. With only 2.4GHz 802.11 support, utilizing the 5GHz band was not an option. But I decided to go ahead and try it anyways, since my previous phone (HTC Fuze / Touch Pro / Raphael), after some careful tweaking, would be able to connect to a “foreign” AP for a minute or two before being kicked off.
Guess what? Association works!
