I called to get help with the router - I set it up but it would not work.The Linksys service rep spent nearly 5 minutes getting all of the serial numbers from the router and wireless card. I had to repeat the numbers atleast six times.Then she had me unplug the internet from the modem.She said the problem was with Comcast! Then she hung up on me.If you buy from Linksys you are on your own. They will do nothing to help you. Buy another brand.
