Which router in specific? My brother bought a mesh system I think it was eero and the range was atrocious in his small apartment! so he returned it and bought a netgear router insteadAs others have mentioned, it's worth paying a little more for a TRI-band mesh system.
This has "a 3rd radio band" in addition to the 2.4ghz and 5ghz channels.
The 3rd band handles the "backhaul" exclusively.
have used the Alien for about 6 months never had to reboot except for updates.My Amplifi Alien has been rock solid.
