Any, there is no Bias from the provider companies. Just make sure that you are getting a "Cable Router" and not a "DSL Router" because the input for your internet connection is different. For brands I recommend Netgear or Linksys. Linksys is probably one of the largest names out there and can be found at any store and has a little more support on the web. Netgear from exprience I have had better luck with and is also a very large brand with a lot of internet help. You should be able to find both of these brands at all common outlets, Best Buy, Target, etc.
