I used this Router for years with great results. We have three computers, two phones and a smart TV. All ran on wireless. The house is a classic Cape Cod with 3 stories and a 30' by 30' design, and we never had an issue with this anywhere in the house. I got a newer router for Christmas and that’s why I replaced this. The "mode" signal lights stopped working, but that doesn't affect the functioning of the unit.
