I moved from DavidC's last build. The client worked fine on that, but obviously there were a billion changes between 19.x and 21.02. Could still be the client doing something wrong that may have been tolerated in 19.x, but I need to figure out what the router doesn't like.
Are you familiar with this discussion? A few brave people are trying to solve/find a workaround for the wifi issues for WRT3200ACM/WRT32X.
They've currently been able to track down the problem and remedy the issue by replacing the current mac80211, with an older one (5.7.5), in a 21.02.1 build. If it works for master as well, maybe this is something we could try out here too?

I've updated to the latest build from the last David built on my WRT1900AC and the fan appears to be stuck on maximum. Any ideas?
It seems like there is a pwm fan control package but I think the kernel is too new to install.
This looks great. I've not had to install a package from source before. Are there instructions around somewhere? My googling is failing me.
There was a change to master quite a while back which I fixed up locally but never got around pushing to my repo, so:

done
check file attributes, comment out the current fan control (/etc/rc./local), enable and start
/etc/init.d/fan_control enable
/etc/init.d/fan_control start
will push that to my repo real soon now, unless sloth gets the better of me.

Excellent! That quieted things down nicely! Thanks a lot.
Just checked in on that thread today and saw the great news! (haven't flashed it yet but hoping it's finally fixed fingers crossed)
+1 for integrating the fix into the divested builds

Looks like this is the only known option for 3200ACM/32X users at the moment to upgrade to 21.02 without connectivity issues, since functionality is broken past 19.07 builds where maintenance has stopped completely; kind of stuck between a rock and a hard place unfortunately. While not ideal, not sure what other options we have for these two devices other than ditch them for something newer (kind of leaning towards that since mwlwifi is abandoned but want to squeeze some more use out of it) or stick with the old builds indefinitely.

Was it 19.02 or 19.07?
yup 19.07, typo
Dear Divested-WRT people, where can I find the patch to enble multi CPU on DSA? Thanks!
FWIW. Not yet ready for prime time?
Ok, it was just to try
I am only getting about 350-400Mb on my WAN port. Any ideas? My asymetric internetspeed is around 750-800Mb.
Linksys WRT1900ACS with latest version - SNAPSHOT r18088+9-9bd9e04b6f
Nothing much default settings and application enabled.
Enables:
- Cake
- Enabled irqbalance
Thank you for getting back to me:
Without Cake my download speed went up to 460-610Mbit. Testet multiple times with speedtest-cli from both my Macbook Pro and Raspberry pi 4. Result are about identical.
Example:
Testing download speed................................................................................
Download: 446.86 Mbit/s
Testing upload speed................................................................................................
Upload: 16.11 Mbit/s
Perhaps this is as expected?
Rather than port things meant for a different architecture, I am in touch with mvneta and mv86xxx drivers maintainers to enable balancing the load across both cpu cores but their time is understandably limited.

If everyone would like to test upcoming lts with vanilla openwrt - to see any regression or bugs.
The easy way - Ansuel's PR #4748, or here.
