Mine sped up. At least to the speeds of my cable modem which is as fast as I need.

I put a wifi network in my nephew's large home. And the new home had those metal studs throughout.
Used 3 wireless routers in Bridge mode each wired to a central wireless router to get good coverage.

Wasn't necessary just to get faster coverage in the rooms at either end of my house that were just getting lower signal.

Also did an unwired wireless router in my brother's home. His TV and AppleTV had a fireplace between it and the main wireless router. Putting and unwired wireless extender in good range of the base router and line of sight with the blackout area bumped blackout area up to the same speeds as the rest of the wireless in his home. And didn't have to pull any wires.
