Dear Kong,
The latest nov15 build 30880 is dropping 5Ghz wifi on Wrt19000acv1 every hour or so for couple seconds. It worked great before with same settings on every previous builds starting June 24 2016.
Yes I know. 2 years after the driver got released it is still crap and as these radios come with a closed source firmware, there is nothing we can do.
I just did tests with the 1200AC last month in my test bed(business environment with lots of clients), and it completely sucks:
-wireless throughput dos not come close the my broadcom or atheros units

-issues with some clients
Thus for me these units are just for playing but not usable in production.
This is very interesting.. My WRT1900AC has been very solid even with the latest build (30880M). I've been on vacation the last two weeks and have probably watched 200 hours of streaming HD video from Amazon via my 5Ghz network (binging on the Sopranos!). Never once has it skipped a beat. Several days I streamed 6-8 hours continuously. I have approximately 15 wireless devices on my network and 5 hard wired devices.
Anyway... since I moved from BS builds to Kong builds, my unit is rock solid.
Dear Kong,
Thank you for comment.
As i mentioned before it worked great with previous builds and something is really wrong with the latest one on 5 GHz only.
What router you will recommend then based on your experience and available builds?

Yes this is a new bug, but the throughput and client issues have been there all the time. I've done tests for several months with several units before I choose our production router.
There are issues that won't affect the regular user, but there are tons of issues that exists which do not exist on a R7000. E.g. one of the features that completely made it impossible for me to use the new WRTs, you cannot exchange one of the antennae with a stronger one e.g. attach one patch panel once you do that you practically get no throughput anymore. This unit needs matching antennae.
This is no issue with the R7000, on some of my R7000 I have detached all oem antennae and only attached one patch panel, it works with full throughput in single stream mode.
I have a large number of R7000 some with 300+ days uptime, some of them have to transfer terabytes each day and work with a large number of clients, even eneterrise routers from cisco,ubnt,mikrotik could not pass my tests. _________________ KONG PB's: http://www.desipro.de/ddwrt/

Do you have any idea why I can get better 5GHz troughput on my wrt1900acs v1 running LEDE build with the same wireless driver as DD-WRT. Specifically I am talking about davidc502's LEDE builds. Has always been that way, not something new. I run a iperf test on the 5GHz after every new build is installed. Openwrt/LEDE is always faster then DD-WRT on 5GHz wireless. Am guessing you are aware of this, just wonder why.

Because they use a 4.x kernel on 2.4 you won't really see any diff, as 2.4 is so slow, that you don't see the improvements, but in 5G and NAT you can tell the difference, it was the same with broadcom when we jumped from 3.10 to 4.4. But these are just little improvements, marvel is so far away from broadcom performance, that this does not matter. _________________ KONG PB's: http://www.desipro.de/ddwrt/

Junior2377, I would stick with the standard 1,6,11 channels on the 2.4 radio if you choose your settings manually. One thing I did notice was that you have WMM disabled - this will basically cripple wireless "N" support on that band. Enable this option and see if that makes a difference for you. You may see slight improvement with short preamble enabled. Only keep long if you have very old devices or get a lot of transmit errors. I would also recommend changing the sensitivity back to default.

Disappointed from Kong's comment. No wonder the MBA which connected via 5GHz upstairs is complainting internet dropping once in a while lately. Going back to EA6900 with Xvortex modded merlin firmware to test.

If you would like to try something else, have you given Openwrt/LEDE a try? I find it runs quite well and has faster throughput then DD-WRT.
This build has proven drivers and folks do not report drops like latest wireless drivers. Here is link to builds if you are interested. Davidc502 provides solid LEDE builds. Here is link

You issue the command fw_setenv boot_part 1 after ssh into the router. After that command do a command reboot and router will reboot to what ever is on partition 1.
@vit5421
I do not do file transfers to the router. I have a separate NAS I use.
I do a iperf test of the 5GHz wireless with each build and Openwrt/LEDE is always faster. Kong has stated that part of the speed difference between Openwrt/LEDE and DD-WRT is the kernel versions.
Dear Bill,
I have a Synology Nas for the file transfer as well and testing read speed from Nas to my laptop. Can you please publish your test data for read/write performance for ddwrt and Open/LEDE one more time?
The Kong has stated about 4.x kernel that "these are just little improvements, marvel is so far away from broadcom performance, that this does not matter"
