MT7615E - is it me, or is it the driver?

sabian2008 · November 21, 2024, 10:45pm

Thanks for the reply.

I tried with (Spain) and without selecting country code and manually (140, 80Mhz width for 5G) and automatically selecting channel.

Ch 140 is 13dbm
Tru setting 5ghz option channels '36 52 100 116' 5o stay out of weak ones.

LilRedDog · November 21, 2024, 11:15pm

Well, that does not show up and, surprisingly, the option for your country code is not set.

Please set it (with your true location; be it Spain; whatever) and repost the wireless cat call.

ercolino · November 22, 2024, 12:04pm

@sabian2008 your device have nothing to do with mt7615. your device have a mt7915 DBDC radio.

sabian2008 · November 22, 2024, 6:58pm

Thanks for pointing this out. I somehow misread the loaded module while greping for "mt" I just read mt76* all the way.

I am sincerely sorry.

Feel free to delete these answers (in case one of you is an admin). I'll open a new thread.

I think show iwinfo with mac address lines deleted and we are good to leave this go

sabian2008 · November 22, 2024, 8:04pm

Oh sorry if it wasn't clear. @ercolino was 100% right, my WiFi chip is MT7915, not MT7615, I read it incorrectly.

Can I open a new topic to discuss the problem I am facing with latency and jitter?

brada4 · November 22, 2024, 8:09pm

Sure, it is fairly open to fine tuune individual setups.
