[SOLVED] Flint 2 (GL-MT6000) - missing band channels 149 - 165 (UK use)

Technical Support for Routers

I've just upgraded from a small Convexa-B (GL-B1300) to the bigger Flint 2 (GL-MT6000).

Initially this looks to have been a backwards step as not only is DFS enforced but more alarming the whole of band C channels are missing?

Initially I had to use 'luci' to change from the defaulted Belgium/Germany region to the GB-UK region, but this still hasn't enabled channels 149 - 165 to appear to be available for selection in the web settings?

From what I can determine I'm running the latest released non-beta firmware of v4.6.2

Why do the available 5Ghz band channels stop at 128?

Where are the next set of available band channels 149 - 165?

What has to be done/configured to be able to access this band which I have neen using on my little Convexa-B for the last 3yrs?

"In 2020, Ofcom in the UK announced that the requirement for DFS will be removed on more channels. Specifically, frequencies in the range of 5725-5850Mhz (5.8Ghz) which correspond to channels 149, 153, 157, 161 and 165 will be allowed for indoor unlicensed use in the UK, without requiring DFS checks before or during use."

I'm currently very disappointed with this WiFi 'downgrade'.

Afaik this band is only for near field communication - like iPhone hotspot. DFS might not be needed but regular usage is questionable.

If the law changed for real (and not only about DFS, which wasn't necessary anyway) OpenWrt needs to adjust the base OS, I guess.

That's not right I'm afraid.

@bruce Could you take a look?

Hi,

Please try the op24 firmware, the CH157 works.

About the DFS scanning, this is a regulatory requirement for WIFI authentication.

Why isn't the mainline firmware working..... as I'm not exactly trying to do anything non standard i.e the mainline firmware isn't working properly?

Thanks for your suggestion though, I will try and see if this is in luci of the x4.6.2 which is loaded on the router.

I have tried to see the Luci of the stable v4.6.2, it cannot.

Probably required to update the closed-source wireless driver, have submit to R&D team to check. Kindly use op24 first if require the 5GHz Band 4

Hi Bruce, is there any easy guide anywhere on how to achieve that i.e. change from 4.6.2 to op24 and will that mean I loose the ability to access the router for maintenance etc which is configured in AP mode via the GL.iNet Goodcloud remote access service?

You will find the op24 version of the GL firmware (so including the GUI!) here: GL.iNet download center

Just upgrade online - but please do not keep settings while upgrading

Hi @bruce & @admon, I just wanted to update this thread and thank you for all your help.

I've now flashed the unit to the op24 firmware as indicated and everything is working as I would have originally expected - after changing from the default BE to GB-UK region, I'm now freely using channel 157 AND with no DFS. My 5Ghz WiFi speed has also increased slightly.

It maybe worth flagging this to engineering to help future UK purchase/users from falling into this trap.

Thanks again

Phil
