If you are a Comcast subscriber and are having issues with your wireless router, you can visit your comcast office and ask for a Wireless Gateway – its a router and modem built into one. Its not a great device compared to the robustness you can get from a modem and router setup if you need something more flexible and powerful, but it can certainly be a great way to not have to pay for a wireless router if you have standard need like most households. It’ll server the purpose of having wifi for most people for sure – and you don’t have to buy a router or pay to replace one if yours fails! Enjoy!
