See attached chart for valid beacon interval numbers. The prime numbers aren't masked by or collide with other wifi access points.

For rf sensitive people, longer time in-between 2.4ghz beacons, such as 293, prevents headache.

Other tip, Try DTIM set to 2 to enable phone and tablet power saving. Preventing wake-locks saves battery and reduces wifi congestion.

See also https://play.google.com/store/apps/details?id=com.pzolee.wifiinfo Wifi Network Analyzer phone app--you probably don't want the 2.4ghz signal more than halfway up the scale if measured from your bedroom.

This post has been super helpful, as I'm in an apartment complex with lots of signals flying around.

My only question: I have client bridges on my network to the gateway. I have the beacon interval set there, and currently on my client bridges as the same. Should client bridges have the same interval? Or is it better off having a different interval than the gateway?

DTIM at 2 has helped a lot as well. Just wondering about the client bridge interval issue.

TIA! Smile

Setting 2.4GHz band to 293 and 5GHz band to 241 seems to be working good on my E4200 v1. I left the GTK renewal at the default of 3600 and so far, NO ISSUES, save and except for the first couple of hours of uptime after I had to de-brick after a bad flash on 40167. Currently still using 40065 K3.x mega.

i would get some errors that would accumulate over time. always still "100%" though. never noticable.

i adjusted the beacons to primes and the dtim to 2. i haven't seen any errors since it's been up and running.

for some reason when my phone first connects it sends packets that are errors. then it quickly resolves the issue.

those initial errors are all I've seen. thanks for posting
