Status: Well, up and running i guess
Reset: Clean install
Errors:
Wifi latency on both 2.4Ghz and 5Ghz band are expectionally high (35ms on speedtest.net whereas 17ms is the norm).
Wifi troughput is exceptionally low only about 35mbit on the 5Ghz band.
I just did a quick test and can't reproduce this on the 1200AC, I get 150MBit using a crappy dual stream N adapter on the 5G and 120MBit on 2G. I'll try an ac adapter later on.
Also don't see any error regarding sirq (the previous created exceptional high sirq), when running iperf test sirq is around 20% and on idle it is down to 0%, just as expected.
Ping in client mode is not perfect I see 10ms. Ping from client to router is <3ms which is okay.
Do you need any more info regarding the low troughput on 5Ghz?
Or could you advise me on what settings you are using on you're WRT1200AC? (Settings like channel nr. lower/upper,)
Most likely it is client depended, broadcom had lots of issues with ampdu/amsdu handling in the past, which alo caused trouble with android and/apple devices.
I used an Intel 7260 and Netgear A6200 for my tests.
The cliënt I tested wifi speed with was a Laptop running Ubuntu 15.04 (Kernel 4.2.3) and using a Intel Ultimate-N 6300AGN.
I'll try my other laptop tonight (it uses a Intel AC7265 network card)

Okay so i've reinstalled 27590M and have been doing some testing.
The following results come from two notebooks one with a Intel Ultimate-N 6300AGN wireless adapter the other with a Intel Wireless-AC7265 adapter.
Both notebooks used 5Ghz wifi.
As you can see latency is pretty high normally it is about 15 to 17ms.
Also, wifi speed, although better then this morning, still isn't what it should be. Especially results with the 802.11AC adapter disappoint, since in the past it 802.11AC performance was OK.
(My Internet connection is capable of 120mbit down 12mbit up)

Up and running with 27950 for almost 24 hours. Upgraded via ddup (router reboot before and after update). No noticeable problems so far. _________________ Netgear R7000: v3.0-r54248 std (11/29/23)

R7000 Here. Much like the BS release for me, UI became unresponsive after a few hours. I've reset to factory defaults and reapplied my settings to see if that makes a difference.
Also, a weird thing involving QoS I'm noticing. If I set download speed limit to 0 (no limit), my wireless AC traffic (5Ghz) goes down to about 50mbps. If I input a large number such as 500000kbps, I get full speed again. This only effects the 5Ghz traffic, and nothing else; not wired, not on 2.4Ghz.. Very strange.
my R8000 was previously running stock FW so not sure if these are new issues or known, though I spent about 2 hours scouring hundreds of posts on half a dozen threads, seems this R8000 development needs some thread locking. (please don't set me on fire jut frustrated and worried about ... being set on fire). Things work for the most part but I have seen some interesting issues during a clean setup.
Wireless Security seems to be flaky on PSK changes, I had to reboot the unit to get it to stick initially. Several times when device/radios are coming back up trying to connect multiple devices get "Password incorrect" .
Adding a VAP requires a router reboot, doesn't show otherwise but does affect the next issue even when it's not visible.
When I try to add a VAP to wl1, the Primary SSID stops working. It continues to advertise as available but when I try and connect to it it advises my password is incorrect. Syslog shows that as soon as the VAP is added (though invisible):
"kern.warn kernel: br0: received packet on eth2 with own address as source address" (repeats at several per second)
Removing the VAP before a reboot (while invisible) doesn't fix, requires reboot.
Let me know if you need anything, I'd like to get a VAP with VLAN tagging working on the 802.11N & G radio.

Ok so today while trying to get a stable 2.4ghz VAP I noticed that the WL0 SSID was not available to any of my devices. I tried everything to get it to come back (factory reset, hard resets, reflashes etc) I eventually went back to stock FW to test to make sure the radio wasn't damaged and it wasn't, so I tried again.
- Factory reset
- Hard reset
- Flash DDWRT.chk
- rename all SSIDs (ddwrt 1, ddwrt 2, ddwrt 3)

This build is awesome...
1. All 3 Radios working.
2. VLAN Trunking working.
3. VLAN Trunking over WAN Port working (When added to switch).
4. Virtual WLAN working (separate VLAN's for Guest network)
All of the issues previously not working are much better.
A Key in this was Erasing NVRAM after setting to defaults and then flashing firmware again.

Status: after upgrade from last kong build (9/7) now 5 days up and no significant issues so far
Reset: Yes
Errors: All Wireless channels show errors for Rx and Tx. 2.4 ghz is not too bad, but both 5 ghz radios do show now ~80k erros for Tx.
Running the corresponding build also on a R7000 with 0 errors after 5 days on both radios for Tx and Rx.
The R7000 is connected to the R8000 via wireless bridge on one of the 5Ghz radios and transfer speed is ok.
Regulatory domain settings seems to have changed. Still have to use US to select appropriate channels for Europe on both 5 Ghz Radios. Europe or Germany does not really work to get the appropriate channels with all modes that are allowed in Europe or work with original firmware.
