Is there a router that outperforms the Zyxel C3000Z Gateway in terms of 2.4 GHz WiFi range?
With IoT equipment linked to the 2.4GHz frequency, I've been experiencing intermittent drops up to several times each day. I decided to purchase my own router and chose the Netgear Nighthawk AX4300. I was able to get the complete transparent bridge mode to operate, as well as removing the gateway totally. When I put the Nighthawk in the recessed media box where the Zyxel was, however, the 2.4Ghz wifi signal is much weaker, to the point where I couldn't connect a security camera outside that had previously worked fine. I tried attaching two of the four antennae, but it didn't work. And, as a reminder, it's in a media box, so I can't put all four in there and really spread them out.
What does usually help is to remove unnecessary SSIDs on the same channel. They each will use "air time" that is a timeslot in which this AP can communicate. The more you have the worse the bandwidth is. That goes not just for the own AP but the neighboring APs, if any.
