MT7603 (2.4ghz) - Main Issue #149

Closed barhom closed 6 years ago

barhom commented 6 years ago

Hello,

I thought that maybe we should try to put together all the different issues that everyone is facing with 2.4ghz on MT7603 (specifically this chipset) into this main issue that everyone can easily follow.

I suggest closing the following issues:

26, #66, #90, #107, #121, #136, #146

And then for anyone that still have issues on MT7603 write us here.

Please always mention which TARGET device you are using and make sure you are on trunk when reporting.

Also mention if you are using disassoc_low_ack='0' or not (default is 1)

@laadayush AFAIK the proprietary driver does not support adhoc so it's not a viable alternative for us. Do correct me if I'm wrong. Thanks.

pparent76 commented 6 years ago

But that proprietary version is vulnerable to KRACK ATTACKS isn't it?

pparent76 commented 6 years ago

Not sure if it is entirly due to mt76 driver, but I tested latest version. After a while the wifi is not emitted anymore. Hostapd process does not respond and is unkillable even with kill -9

Then any network command like ifconfig or hostapd or /etc/init.d/network restart, ... is freezing the console. (Even ctrl+c does not reply). Although, the network itself is still working. If you want to know more I still have my router in this freezy state and I can try other commands.

I've already seen this, but I cannot remember when, and what was the solution.

you should've used mt7602 chipset. is better than 7603

slthomason commented 6 years ago

Haha ... nice, but already invested a lot in this hardware, and it has 7603.

I have massive Wifi disconnection problem with Archer C50 and OpenWrt 18.06 on both 2.4 and 5 GHz. Option option disassoc_low_ack '0' doesn't fix it. I observe the problem only on Lenovo Yoga Tablet 2 which has no problems when using different router. On Xiaomi Mi 4, iPad, Runbo X6 ang HP laptop there is no such problem.

I am closing this issue. I hope that everyone who have issues with MT7603 opens a new issue writes a detailed report on what the issues are.

@CR-Ryan I have the same device ZBT WE1326 and haven't been able to get 5Ghz working. Can you please point me to the last working commit and some sample settings corresponding to it. Thanks.
