E51 WLAN Setup Issues

Question

Hi,
I know this has been discussed before, but after searching and trialing I've got nowhere.
Just got my E51 and trying to connect to my home wireless network. Appears to connect fine, try to start browsing, no data is transferred and eventually times out...
I've tried wizard setup and manual setup - both give the same results.
Router (Netgear WGR614) setup:
WPA-PSK security
SSID visible
Phone set-up
Network status Public
WLAN mode Infastructure
WLAN security mode WPA/WPA2
WPA2 security mode off
Think that's about it. Any solutions as to what causes this? I fear it's a firewall setting as allows connection but no data transfer. I disabled the SPI firewall on the router and that didn't help.
Thanks for any help!

I don't know what exactly caused the problem, which consisted of not being able to connect my Nokia E51 to the WLAN Router but if the security settings were disabled. Whenever I tried to enable the security settings with WEP/WPA on my WLAN router, although the access point was duly detected, and apparently flawlessly listed, it would no longer be available when actually trying to connect, as it would return the error message "WLAN not found".
After reading a few things about security issues, (http://www.wi-fiplanet.com/tutorials/article.php/3​672711, http://www.practicallynetworked.com/security/04120​7wpa_psk.htm) I decided that there is no way I could accept to connect to WLAN without security encryption.
By trial and error I managed to enable the security settings on the WLAN router AND successfully connect with Nokia E51 only after I did this:
1) Changed the SSID to some very exotic new name, completely different from the previous default name (supplied by the manufacturer). I noticed that the default SSID had become a known access point (AP) to my nokia phone when the security was disabled. With security enabled, it no longer worked.
2) Set up the wireless security to WPA authentication type, TKIP encryption, PKS.
3) Chose a 15 (or more)-character-strong passphrase and set is up in the wireless router security settings.
4) Had the WLAN assistant of my Nokia E51 update the AP list.
5) Once listed as new, unknown SSID, I was able to set up from the phone my WLAN AP, via the OPTIONS tab where I was finally prompted for the passphrase. (Same prompt would NOT work unless SSID of a previously successful, unencrypted AP is changed)
The device resolved the connection which worked fine ever since.
I think that there is a bug with Nokia E51 which does not actually update the access point list and does not reload all of the details of a recently reconfigured AP which used to work fine with disabled security settings in the first place. The mobile phone can be forced to completely refresh the AP list (in Connection Manager> WLAN assistant) only if the SSID of the AP is renamed in the the router settings. It seems that only afterwards would the security handshake between the devices finally work out and establish a proper connection. There is definitely a bug with the Nokia E51 wlan manager!
