wifi setting on RT-AC68U

[naper82]

I installed 384.17 on RT-AC68U with hard reset a few days ago. There are 4 wired devices and about 30 wireless devices (mostly smart plugs/bulbs). I have minimum setting except the wifi 2.4 Ghz setting as stated in this old thread https://www.snbforums.com/threads/guide-troubleshooting-wifi-issues.12825/

Due to this, you should set channel width to 20 MHz on that band. A 40 MHz connection would require you to overlap no less than 5 channels. Highly unlikely you will get a reliable 40 MHz connection in any urban area with so many channels overlapping. Yes, it will cut your maximum performance in half, but if you want a STABLE connection on the 2.4 GHz band, there is little you can do about this. Otherwise, the 5 GHz band is your only solution.

Does this still hold true? The wifi speed is much slower than default 20/40 MHz though.

I have experienced wifi drop a few times, mainly during a online meeting calls, there were a few seconds drop and then connect back. I've tried restart the modem and router. Is this version 384.17 stable enough or should I try a previous version(please recommend one)? How can I troubleshoot to find out if issue on my router or ISP?

Thanks!

Yes, and it will become increasingly relevant, as the 2.4 GHz band will continue to get even more oversaturated, making it impossible for anyone to monopolize a whole 40 MHz chunk of the whole band spectrum available.

I can't reliably use 2.4 where I live, WiFi Analyzer looks like a straight line there's so much congestion, individual users are difficult to pick out sometimes. 5g works fine though, fortunately.

Thanks. What do you suggest I start to troubleshooting?

5g is super but there are devices that doesn't support 5g yet. Also coverage is short

To put the bandwidth issue to a test I monitored my Internet connection via the graphs built into your firmware for my AC68U. While my wife was on a Zoom session the upstream and downstream feed rarely exceeded 60kBps (round that to 500 kbps). Not exactly a strain even on 2.4GHz/20M.

true, most of time, speed is not the concern, stable is
