N8 frustration - WLAN/FM radio/battery life

Question

Boy, were my hopes ever dashed?
Great to look at, great to hold in one's hand, nice to swoosh between homescreens, photo-taking a treat.......I could go on; not much, but I could go on.
How frustrating is this phone?
Anytime I plug in the supplied headphones to listen to the FM radio, the app freezes and won't close down. It finds all the stations, but won't let me pick one or assign an ID to any of them.
Battery life seems much less reliable than that of my previous 5800, but I'm willing to make an exception with regard to the fact I'm regularly on the screen trying to work out how to use the thing! IF I ever manage to get to grips with it, or if it ever gets the fix that it needs, this issue may well be forgotten.
The 'messaging' icon was lost during an organisation of the menu screen, and cannot be found or replaced, even after a reset. 
The most annoying thing, however, is the internet connectivity - or lack of! So far I've had trouble with downloading updates to allow facebook and twitter to work - what's with apps for 'social networks' AND 'communities'? - accessing OVI stores requires regularly re-signing in, mailbox settings are proving problematic amongst other things, and connecting to my WLAN at home....? Nae chance.
I have a BT HomeHub (one of the black numbers) which allowed a laptop and a Wii, no problem. This phone? Found it, took the key, will connect, but any attempt at web browsing is met with a window stating 'Invalid server name'. After a long call with BT this morning, the HomeHub was reset, and this seemed to clear everything and allow access. Come teatime, however, and we're back to the 'invalid server name' response. What is THAT all about? How can we overcome this?
As a point to note, I tried connecting to my sister's Virgin Media hub at her house a couple of days before - easy! No problem whatsoever. A chap in the Vodafone shop recognised this from the anecdotal evidence of other customers and said perhaps a WPA/WEP diecrepancy may be the cause. It is at this stage that I become disconnected from any sense of understanding.
Can anyone enlighten me, please? All I want is to get this working and get on with my life. A quick scan of other discussion topic headings suggests to me that this may be a winter of discontent for many N8 owners. Are there any knowledgable folk out there with some practical suggestions/solutions?
It's late. I'm tired. Good night.
Best regards

I also have had problems with the wlan connection on my N8. The phone would connect to my wlan no probs. But when trying to connect to the internet it would say "failed. Access denied".
Then tried to connect to the internet using my network providers access point and got the message "Invalid server". Out of frustration I rang the Nokia Australia call centre (located in the Phillipines) and the woman I spoke to there told me to perform the following steps.
1 Switch the phone off for about 30 seconds.
2 Switch it back on and wait untilthe home screen appears.
3 On the dialler type *#7780#
4 Wait for the phone to restart.
Did all that and guess what. It solved my connection problems.
