I've noticed when using my ipad that every two or three minutes the wifi indicator on the top left with cut out for half a second. My iPod touch doesn't do this, has anyone else noticed this?
Yup, happens to me to unless I'm in the same room as the router. I have a Linksys WRT54GS and changed the channel settings to 11 instead of 6 and it seemed to help when I'm in the living room or kitchen. Power cycle your cable modem and try changing the channel to your liking.
