Being recently blessed with a free Fon router, I spent some time researching how to connect to it with the Nokia E61’s wifi.
The problem was that I simply couldn’t connect, event though I had the correct password set. Googling turned up a tip, which seems to work.
First, you can’t create an access point directly from the WLAN discovery tool (Menu -> Connectivity -> Conn. mgr. -> Availab. WLAN) if the access point is encrypted. You have to go into Menu -> Tools -> Settings -> Connection -> Access points and define a new one there.
Now, according to this post, the Fonera uses one transmitter and quickly switches between the 2 SSIDs it broadcasts. By turning off the automatic power save in the E61, you can “lock” it to the SSID you want (which is the private one, in my case).
Turn off the power save like this:
Menu -> Tools -> Settings -> Connection -> Wireless LAN
Press Options and choose Advanced settings. You’ll get a warning, which I duly read and noted. Continue, and choose to disable the Power saving feature.
Note that this will probably drain your battery if you use it for push email. Just keeping a screen session up in putty drained by battery in one evening.
