Glad it's all working nicely.
Your wireless channel is a little greedy IMO. I'll explain why...
Your wireless is on channel 4. Nothing wrong with it although it does overlap with 1 and 6 which most devices use.
You will be picking up interference from those on 1 and 6, and also interfering slightly with both main channels.
You'd be best to choose channels 1 or 6 or 11. Whichever ones least populated.
It is very easy to assume that each of the 13 WIFI channels is totally seperate from the rest and, of course, if you were allocating the way WIFI works you wouldnt start off where we are now
Wireless N makes things even worse because it grabs an extra 5 channels as well!
Best to use inSSIDer or similar to find the "best" channel to use to avoid other devices, fortunately "most" routers seem to come preconfigured to use channel 1 so never recommend your neighbours to change it
