While changing your router might resolve the problem, there is no guarantee of that.
I would like to suggest that, if you do get a replacement router (sounds like the one you have should still be under warranty), don't tell them that it's causing a 10053 error, as most people would just look at you and say "What's that?".

Instead, tell them that the router is breaking your internet connection on a regular (you can even tell them that it's every 8 minutes) basis. If you are dealing with a non-tech, which most of the returns people are, they'll understand that better.
