Issues with 2.4GHz using Merlin 380.68_2

[mustafa803]

Hi.

I am using Merlin 380.68_2 on an Asus RT-AC1900P router and I noticed something out of the ordinary...I upgraded to this software 5 days ago coming from the version 380.68...I dont know if this problem existed in earlier firmwares or not.

I normally have the 2,4GHz wireless set to channel 11. When I checked the wifi manager on my phone it showed that I was using channel 7. So when I logged into the router it said channel 11 but when I hovered over the wifi signal at the right top, the white box said channel 7.

So I went through all the channels from 1-11 and also the GHz channels one by one and I noticed this issue only in the 2.4GHz and I confirmed it using my phone.

Here are my findings for 2.4GHz when the channel is set to 20/40 MHz:

1------------1+3
2------------2+4
3------------3+5
4------------4+6
5------------5
6------------6+8
7------------7
8------------4+6
9------------5
10------------6+8
11------------7

I tried using 20MHz only and I got the following.

1------------1
2------------2
3------------3
4------------4
5------------5
6------------6
7------------7
8------------8
9------------9
10------------10
11------------11

When I set the bandwidth to 40 MHz I got the following

1------------1+3
2------------2+4
3------------3+5
4------------4+6
5------------5+7
6------------6+8
7------------7+9
8------------6+8
9------------7+9
10------------10+8
11------------11+9

Is anyone else having the same issue?

Set channel bandwidth to just 20MHz and re-test, I suspect it's showing 7 for the extension channel

I did that and I also included the 40MHz in the original post......It looks like when I set it to 20MHz or 40MHz it is fine...but the issue arises when I pick 20/40MHz it

Since I upgraded to Merlin 380.59 last year I have noticed that the 2.4GHz when set to auto it keeps picking random channels..like 2 3 8 or 10. Before 380.59 firmware update, it would only pick channels 1, 6 and 11.

That is the reason why I have the channel manually set to 11 since last year on RT-N66U and AC1900P.
