I did dirty upgrades to my Asus RT-AC68U from AsusWRT-Merlin 386.4_0 to the two alphas and now to AsusWRT_Merlin 368.5_beta1. All appears to be working well, I didn't encounter any problem.
The
Disable 11b
option on the 2.4 GHz WiFi when
Wireless Mode
is set to
Auto
still makes the clients disconnect a few seconds after connecting, but, unlike 386.4_0, the option can be disabled by the WebUI, no need to use the terminal.
Thank you RMerlin!
I think that this line,
Feb 22 08:32:35 acsd: eth6: COEX: downgraded chanspec 0x1909 to 0x100b: channel 6 used by exiting BSSs
, refers to the fact that your 2.4 GHz
Channel bandwidth
is not set to
20 MHz
and when the router detects another wireless network using a channel overlapping with its own, it correctly falls back the bandwidth to 20 MHz and informs you by that line. Check this soon to be 10 years old
article from this very website for more information.
You should manually set the
Channel bandwidth
to
20 MHz
, also set the
Control channel
to
1
,
6
or
11
, depending on which is the most unused.
For the other lines, searching for 88:d0:39 OUI reveals the owner to be
Tonly Technology Co. Ltd
, formerly
TCL Technoly Electronics(Huizhou).,Ltd
, which unfortunatelly means nothing to me.
