ChannelHog - Monitor And Force Maximum 5GHz Bandwidth

[SomeWhereOverTheRainBow]

Use wl_ifnames to get the list of WLAN interfaces.

admin@stargate:/tmp/home/root# nvram get wl_ifnames
eth6 eth7

That is all fine and dandy, but we are only concerned with the one specific to the 5ghz bandwidth. do they follow numerical logic in this case?

GT-AX11000-9600:/tmp/home/root# nvram get wl_ifnames
eth6 eth7 eth8

RT-AX88U-C7C0:/tmp/home/root# nvram get wl_ifnames
eth6 eth7

Edit: Revised logic (abit overkill) per @RMerlin

port5ghz-1="$(nvram get wl_ifnames | grep -oF "$(ifconfig | grep -F "$(nvram get wl1_hwaddr)" | awk '{if (NR==1) {print $1}}')")"
and
port5ghz-2="$(nvram get wl_ifnames | grep -oF "$(ifconfig | grep -F "$(nvram get wl2_hwaddr)" | awk '{if (NR==1) {print $1}}')")"

@Adamm , the revised logic should take care of worrying about catching the wrong interface between different models.

Yes. 0, 1 and 2 (if it exists).

 

[DJones]

Hate to bump this but this would be great on my gt-ax11000 if it works. Hopefully support can be added.

I tried to install it - but the install script says that my AX-11000 isn't supported...

[*] ChannelHog currently only supports the RT-AX88U / RT-AX86U / RT-AX58U

Try now, got rid of the model check.

Edit; Just tested, need to make some small fixes.

Thanks. I installed it. At what time is it supposed to restart the band? Because right after starting nothing happend...

thanks

Everything should be in working order now. If anyone with a dual radio device could test the latest version and let me know.

 

[JGrana]

@Adamm , I installed on an AX58U (dual radio). Working fine.
I did a few "sh /jffs/addons/channelhog/channelhog.sh check" after I installed and it showed 160Mhz every time.

 

[stebrick]

I wish I could use this addon on my XT8 for the 5Ghz-2.

Problem is, it's 5Ghz-1 supports 80mhz at most. Only 5Ghz-2 supports 160mhz.
If I use this addon, its 5Ghz-1 brand will just keep restarting? Is there any workaround?

Its a Bash shell script so it is pretty easy to read through and modify if you want.

I would search for “160” and see about changing it to “80” for example.
@Adamm is a very good SW developer and I have found his code to be pretty easy to read through and modify.

Ahh, the beauty of Free and Open Source. ;-)

I have found his script to be beautifully written, but unless the average user takes the time to investigate what each variables individually do and also understands basic script logic, they can easily find themselves breaking something trying to modify @Adamm scripts despite the ease and beauty at which the script was written. That is because @Adamm does not simply just write script, or just a good SW developer (although he is both of those); however, he has an intricate, and intimate, understanding of how his script interacts with Asuswrt/Merlin inner workings. It is not something that can always be easily reproduced, or modified; even though, for @Adamm it might be as simple as changing one or two lines of code.

I further digress by simply stating I, and hopefully the rest of the community addon users (and/or developers), are thankful for everything @Adamm does and continues to do. Simply make your request known and as @Adamm finds the time, I am sure he will implement patches for these "newer" supported routers. He cannot simply move at the speed that these routers are showing up on the market. He first has to do like any other diligent developer would do, which is research, and test, before dropping in patches or new releases; this requires time and patience.

Just a guess but it should be as easy as putting lines 190-191 in its own if statement (assuming nvram get model returns XT8 as a model name)

targetbandwidth="160MHz"
if [ "$currentbandwidth1" != "$targetbandwidth" ]; then
    if [ "$(nvram get model)" != "XT8" ]; then
        restart5ghz1="true"
        restartradio="5GHz-1 "
    fi
fi

something like

nvram get productid

may work.

e.g.

RT-AX88U-C7C0:/tmp/home/root# nvram get productid
RT-AX88U

Appreciate the kind words.

I’ll update the logic this week to support this model. Hard for me to find edge cases like this sometimes with so many models in the wild and limited testing devices.

Much appreciated. I didn't expect so much kind response to my request. I'm not very familiar with these stuff and not sure if model specific is good idea or not, given that we have so many models outside in the market. Maybe, if possible and not too troublesome, it would be better to just let the user decides which 5Ghz band(s) it should monitor?

Thank you again for all the insight above.

BTW, GT-AXE16000 radios aren't in the same order as other models.

wl0: 5 GHz-1
wl1: 5 GHz-2
wl2: 6 GHz
wl3: 2.4 GHz

75% of the development time on 386.8 was spent dealing with this (even Asus's latest released firmware for that model still had a few webui issues where the wrong settings would show for the wrong radios, so I had to fix it).

 

[Yota]

wl0: 5 GHz-1
wl1: 5 GHz-2
wl2: 6 GHz
wl3: 2.4 GHz

Why, is it the complexity introduced by Asus, or Broadcom?

This will drive a lot of wifi-related script developers crazy

 

[Volfi]

Could this script be used to restart the Wifi when DFS is detected?
My Wifi is running on channel 120, but several times a month it "detects" DFS (probably a false positive) and moves to channel 36 or so and stays there.
Could this script detect it and restart 5GHz?
