I've noticed this as well - it stays at 1ghz the vast majority of the time and even causes processor usage spikes up to 40% sometimes during minuscule tasks. I'm going to test with both ondemand and performance to see how they compare. With my R7800's I always ran performance because the power consumption differences were so negligible and the router temps only increased a degree or two. Curious how this will respond as well. I know that many stock firmware's don't allow so many frequencies to be selected, but rather two or three at most and most stock firmware have very aggressive up sampling as well.
I described it earlier: used root+ssh to install OpenWrt in memory then by using ubi. All went ok and I had luci installed. Then upgraded to a new snapshot via UI and rebooted. It was stuck on purple led no matter what I tried. I had to disassemble the unit and hook up to the console port. Was able to go though steps all the way this time. A bit hesitant to upgrade again though
Its a minor issue though. The biggest one is the inability to use 160mhz channels normally and missing upper 5ghz channels. I dunno why people turn other way from this problem in a supposedly 'recommended' WiFi router.
Just for comparison. My phicomm K3 which I got for 40 bucks shipped 3 years ago is based on (shunned) Broadcom and still works perfectly with OpenWrt since 19.x (after tweaks) - irqbalance works, 1gbps nat works, 3(!) 160mhz channels work, no hardcoded regdb. Uptime is till next power loss.
I hoped for upgrade to ax (no real need, just curiosity, I guess) but oh well...
Well, to give some perspective:
I have sysupgraded my R7800 about 1340 times since 2016 (for testing my community builds), and about 20-30 upgrades have failed. Some times due to bugs (to be debugged) in OpenWrt, but a few times just for unexplained reasons, as the next sysupgrade try with the same image has succeeded.
I'm using 160MHz on channel 36 and I have the ability to use channels 100-165, albeit that some of those are DFS channels but it'd be illegal in the States for me to transmit on those frequencies if it would interfere with radar.
Im able to use 36 only too but it's congested (other folks are stuck with 149? only) Dfs doesn't work on this router it seems? In my area I see several provider-issued routers working in DFS range with no problem. Meaning they detect no radars.
I see Verizon, Xfinity and Optimum SSIDs all from different hardware vendors all operating in DFS range. I got Verizon cr1000a (another toy, same platform as this router) and it doesn't work with DFS in the same way: only 160mhz channel is 36 and no upper 5hz channels available
probably under the hood all using the same broadcom chip/wifi soc. isp provided modem are 90% broadcom supplied
Anyway ath11k is not enough mature currently but honestly the only alternative is the mtk driver... everything else is either not opensource or works half way or is trash and you need to use downstream stuff to make it work....
Not mature enough 'yet' is all right. But being forever on vendors mercy with hardcoded reg db and what else is a red flag. I'm not even sure how could this be called open source driver.. even Broadcom s proprietary drive is not that ugly.
