I have been using this router for about a year now but only recently I am noticing that all the devices on the 2.4Ghz network are disconnecting about once a week. The 5Ghz network stays connected.
As mentioned I bought this router about a year and a half ago. I am on the latest firmware. I connect the wifi router to a AT&T modem in router mode. I believe I have set this up correctly in that the AT&T modem/router is in passthrough mode to avoid any NAT issues. I followed this guide: http://www.dslreports.com/faq/17734
Over the past year or so I have bought and added multiple smart home devices as well as other peripherals for the house. In total I have about 30 devices connected to the router, most on 2Ghz and some on 5Ghz.
However in the past month I'm noticing the following: - All the devices on the 2.4Ghz network disconnect about twice a week - If I try and connect a new device (e.g. my phone) to the 2.4Ghz network it fails to connect - Restarting the router fixes the problem - No issues with the 5Ghz network at all
What I've tried to solve this: - Shifted devices between 2G and 5G (this solves the problem but some of my devices are too far away for 5Ghz) - Turned of Beamforming and Airtime fairness (I have hesitated turning of MU-MIMO as with so many devices this might significantly degrade my network performance) - Disabled QoS - Assigned IP addresses to all smart home devices so they aren't constantly searching - Made sure my firmware is up to date - Tried disabling the firewall - Turned off smart connect
Disabling Beamforming and Airtime fairness had the best impact. Previously the devices would disconnect 1-2 times a week. Since disabling over a week ago the devices have disconnected only once.
Additionally, this only started happening a month ago. Unfortunately I can't remember what changed.
