Upon loading this firmware version r41954 on my r9000, interface and device becomes non-responsive. Power-cycling successfully resets the device. Upon boot, it's still using the previous firmware version r41892.

firewall problems https://svn.dd-wrt.com/ticket/6947 this will probably explain many things.... (that i havent mentioned yet)

I am talking about WAN<>LAN throughput, so router performing NAT.
If you keep the up_threshold at default 80 throughput is around 650 Mb/s
If you lower the up_threshold to 35 or 20 you can get 900 Mb/s.

I am not talking about wireless.
I did test wireless 160 Mhz with 1733 Mb/s. But I did not get more than 700 Mb/s effective throughput WLAN<>LAN, but that could well be that the laptop is the bottleneck. The wifi 6 chipset should do more but I do not know how it is connected internally

the WLAN/LAN routing performance of the R7800 is ~700mbit/sek

no further testing needed - the value is known

i was talking about WLAN (not WAN) to LAN
WLAN is encrypted and needs more CPU cycles as unencrypted traffic

simple iperf3 test @500mbit between WLAN and LAN client results in nearly 100% CPU usage of 1 core

I did some limited testing between Kong and BS and was not able to find a difference with my limited testing and when looking at the load average: see: https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=322366&postdays=0&postorder=asc&highlight=r7800&start=15 about the thenth post

Just a thought, when I started reading about the performance (CPU governor, core affinity etc) I noticed that that my interrupts and core affinity settings were different from the ones reported.
Maybe it is just updated and everyone else has the same settings but I post them here anyway for you to check.

[Alozaros]

well... egc, do you use any core lines in start up?
or this is plain output....??
How does max CPU settings affect this performance or you are using ondemand...???

I was using MAX CPU for a bit of a time, but i have some
cooling mods and extra thermal pads here and there in my R7800, so never had an overheating issue..with max CPU

Currently still using few CPU core lines to balance cores, and ondemand CPU with 35 threshold, but haven't seen the recent CPU cores output, it seems BS does balancing and those lines my only become obsolete and interfere with the firmware builds...
I guess i have to be more observant on the subject...
So, far for my needs R7800 its working ok...

Unfortunately, since a few builds, clients cannot see the AP any more when Wireless encryption is active.
All clients (different brands) cannot see the Wifi Router any more
It seems the bug has been introduced with 12-21-2019-r41771. Build 12-10-2019-r41686 still works fine. For all later builds, Wifi is not visible if encryption active.

Router Model: TP-Link TL-WDR4300 v1
CPU Model: Atheros AR9344 ver 1 rev 1.2 (0x2122)
Wireless Chipset: AR934x 802.11n WiSOC
Wireless mode: AP (ath0 + ath1)
Encryption: WPA Personal + AES

well that looks like a problem..
