Why would you replace a router with a wifi router, the 4011 has a WIRED only version and better anyway for the same price point is the RB5009?
I am thinking about it. The only similar device is the 4011 with wireless.Getting a modern router with horsepower is certainly recommended.
Unaware of any method to avoid mangling in this case.
