i currently have a dlink router that has 2.4GHz and 5GHz. what the problem is, both the signals are not strong enough to reach the other end of the house. i am looking for just one repeater or range extender that will extend both of the signals to the rest of the house. so far all i can find is that they will only boost the 2.4 or the 5 it will not do both. any suggestions would be greatly appreciated.
