Thanks so much for continuing to offer help...it is much appreciated. I tried the MAC suggestion, and no luck. I also went through the troubleshooting link with no luck. The final suggestion you made is a bit over my technical head, so to speak. I know how to log into my router, but ensuring it is open to the specs you mentioned (802.11n), I am not sure how to do that. I have a netgear wpn824 (v2) router, so if you have any thoughts on how to confirm the last suggestion, I am all ears.
I might also mention that the iTouch shows the network is connected and has all three bars light up in blue. I receive the error message "server stopped responding" when I attempt to use anything that requires Internet connection (safari, iTunes stpre, etc...). Not sure if that brings any additional suggestions or not.
