Thanks for the information. The router is a piece of junk. I tried your instructions and it seems to not disconnect as much. We see how it goes after a few days.
I haven't looked at the pages of replies, but I do know there is new firmware released for several of the NetComm router/hubs. I'd strongly suggest calling Rogers Tech Support.
Your DNS changes seemed to have helped my situation so far.
Is there a way to change the DNS settings on my iphone and ipad as well, while I'm connected to my wi-fi in my home?
