Problem with Westell 7500 router

[Jacob Lyde]

So, I have had this router for almost 2 years now, along with Frontier ISP. But recently, whenever I try to do something that requires a decent amount of data, like watching netflix, it will just stop working. It will work again if I do either of these: 1. Reset the router. 2. Diagnose the problem on windows 7. When I diagnose it, it searches for the problem, but right when it looks for a problem in "name resolution", it works again and says there is no problem. I have never had this problem before, and it is a pain in the ***.

Set the MTU to 1492

I agree with JoBeard, the MTU is typically the problem in this type of problem.
