AX88U 5GHZ channels Missing :(

[immi803]

Hi everyone,
I got my new Ax88u and it landed me into weird problem regarding 5ghz
First of all, i got it from Amazon UAE and it's my trusted source for stuff like this, now problem is i can't see 5ghz channels above 140 , and channels work in my territory are above ones, i can't see any region changing settings in wifi professional tab as well
I'm quite confident that it's not Chinese version as first start was English etc
Any help is highly appreciated

I got furstrated and tried every possible way like hard reset (wps button method), going back & forth merlin to official firmware etc but of no help
My devices can't see 5ghz

SSH into the router and check the region is set correctly.

# nvram get territory_code
UK/01
# nvram get wl1_country_code
EU

I guess yours should say "AE" somewhere.

Also try manually selecting a bandwidth of 20MHz and seeing if the channel list changes.

What should i do to correct it?
Yes , 20mhz changes the list but non show channels above 140

The device you have appears to have been manufactured for the UK market (which would explain the channel list).

Unless that is typical for WiFi products sold in the UAE I would return it to the seller and get a replacement that was manufactured for your country.

You're right absolutely
But is there any solution at hand to amend it using ssh etc? Please help as i bought it on my visit to Dubai and returning it is not easy for me especially in this epidemic situation

Not really. There might be ways to hack it (but I doubt it) but such discussions are against these forums rules and any such posts will be deleted. You'd have to look elsewhere for that.

Can you not just use the channels from 36 to 140 (like the rest of us in the EU )?

I wish i could, unfortunately I can't, working channels in my region are 149 - 161
Can you just pm any link for any guide elsewhere? I know it's CFE i need to edit but how ? Can't risk without a guide at least

I don't know what you mean by this. According to the WiFi database all channels between 36 and 165 are usable in the UAE.

Sorry, I honestly don't know of any (but then I've not looked for it). The RT-AX88U is not like the old RT-AC68U's. It has an encrypted CFE for one thing meaning that you can't just flash a replacement CFE onto it.

If i have been living in UAE , it would have a non issue to return to amazon, i bought it on a visit to Dubai and it was just before pandemic burst out in asia
And i just unboxed it tonight as i was going fine with ac68u

Sorry, you've completely lost me. I thought you were living in the UAE. Are you saying you're now living in a different country?

Yes

 

[ColinTaylor]

Yes

I understand now. I'm sorry I can't help you.

 

[immi803]

I understand now. I'm sorry I can't help you.

Thanks for your time

now problem is i can't see 5ghz channels above 140

Why do you need them? 160MHz width works ONLY on 36-128 channels. https://en.wikipedia.org/wiki/List_of_WLAN_channels#5_GHz_(802.11a/h/j/n/ac/ax)
see the large table on the link

He never mentioned 160MHz (or any other bandwidth). Besides, only channels 149 to 161 are allowed in his country which means his maximum is 80MHz.

149-161 have a lot of power, but are useless on the RT-AX88 model, a simple and best solution is 36-48 channels with a width of 160 MHz. On channels 149-161, this router will have two times less performance, maximum 2400Mbps at 5Hz. Therefore, it makes no sense to suffer from the absence of these useless channels.

Sorry, what is it about "only channels 149 to 161 are allowed in his country" that is not clear?

I did not notice this message , it turns out this router is useless for this region.

Yes, in my country 80mhz is max supported until now and on channels from 149 - 165
My devices can't pick lower frequencies
