I just found this comment on Nokia's site:

and repeated here from May 2006:

"Maybe my experiences connecting to WiFi access points will help.

First attempt worked straightaway. Connection Manager detected my father's WEP-enabled network with 64-bit encryption, so entered the key (remember to select HEX under WEP key type), and no problem thereafter.

Second attempt also worked straightaway with an unsecured network at a bed-and-breakfast.

Then, got home to the UK from the US and no luck! Could connect to my neighbor's unsecured network, but could not download Web pages (got the "Network problem" message even though Connection Manager showed bytes being sent and received).

Couldn't connect to my own WEP-enabled network either; it was detected, but no WEP key entry was enabled. Solution was to set up the connection manually. In Connection Manager, select menu (with hard key) -> Tools -> Connectivity Settings. Click the Connections button and select the network and click Edit or add it with the New button. On the first page, enter network name (if necessary) and select WLAN as the Connection Type. On the next page, select Infrastructure as the Network mode (Ad hoc did not work for me) and WEP for Security mode (if appropriate). On the next page, enter the WEP keys (remember to select HEX for WEP key type). On the next page, click Advanced settings and go to the IP Addresses panel - I used 'Auto-retrieve IP address' and 'Auto-retrieve DNS' (others suggest static IP address, but DHCP works for me). Click Finish.

I was pretty frustrated after two painless connections to fail with my own home network, but a little patience paid off.

I love my 770, and ignore the reviews that complain about what it can't do. I bought it to lie in bed or sit on the bog (toilet) and surf. It's a pity some people seem to give up after not connecting instantly the first time, and many of the problems and questions are to do with WEP keys, which are not specific to this device. Oh well.

Good luck!

Jerry"

This worked for me. I am using the 770 with the latest 2006 OS.
