Wifi connection with netgear router DG824M - one solution
Netgear DG824M
I'm still having a problem with the encryption issue but have at least found one solution to another security issue and thought it might help others so i am posting:-
If you have mac address filtering turned on (netgear describes this as only "trusted PC's" can connect) , you may find that you get an IP Address clash when you try to connect your iphone (or some other apple equipment)
I found that this resolved if i selected an "reserved IP address" for the iphone - in my casei chose 192.168.0.10 (since the router allows up to .51)
(the phone otherwise took 192.168.0.3 which clashed with another device)
This was not an issue when "trusted pc's" feature was turned off on the router
