Same To me. I have Asus WL-500W router at home, WPA2-PSK(AES), password similar to this "lIGf@91pY0TnFY!Jh@7LjTUlsL3ZPY", MAC address filtering. My old Nokia E51 works, my Touch Pro Works with it. When i try my one day old Nokia E72 it does not work, the same like others:WLAN: Unable to connect. Wlan Network not Found. E72 works at my work wifi, which has the same settings but without mac filtering. Have no idea what is happening, all is setting correctly. MAC address of E72 is allowed on router. It has the same settings like E51, but E51 works like a charm E72 does not work. What is wrong?
As already suggested, you could try disabling the MAC filtering from the router, just to outrule possibility of a typo while entering E72's MAC address to router settings.
Have you tried swithing a WLAN channel that your router uses?
Log in to your router's web management pages (check router's default IP address and username/password from it's manual) and switch of the "Automatic" channel selection mode. Try few different channels, like 1, 3, 6, 9, 11, if one of the channels happens to work any better. Note that in case you have set your router to use channels 12 or 13 (or in case "Automatic" channel selection mode has decided to select channel 12 or 13) you must have a SIM card inserted and some other than "Offline" profile enabled on your phone since Offline mode (i.e. airplane / flight mode) won't allow your phone to operate on higher channels than 11.
In case you have configured your WLAN network (SSID) to be "hidden", try disabling hidden SSID mode on the router.
Asus WL-500W router seems to be a pre-standard 802.11n device so might be worth looking in to your router's WLAN settings and see if playing around with router's WLAN operating mode and settings improve the situation. First of all ensure that your router is not set to operate in 20/40MHz mode (set it to 20MHz only) assuming that the router is in default 802.11b/g/n mode. You could also try disabling the 802.11n mode completely by selecting a 802.11b/g mode (if available).
You should probably also check that you're running latest (2.0.0.6 ??) firmware version on your Asus WL-500W router since there seems to plenty of complaints regarding WLAN connectivity and stability issues (in general, not specific to Nokia handsets) with this particular router model.
