My goal is to have some info about different atheros devices collected at one topic that helps to decide what beta version should be used for a specific model when migrating from stock firmware to dd-wrt for low end devices with limited flash and memory.
The version must match following criteria:
1. run without issues for the standard settings router, access point, repeater configurations
2. long term running stability, no need to reboot because of performance decreases by uptime (low memory issues for example)
3. no additional issues with WLAN on the device (compared to the stock firmware), improvment and fixes welcome, may include minor WLAN setting changes to work with the same settings the stock firmware uses
4. if you have a different (second) beta version suggestion as recommend version for a device please make a note on a benefit of this version and the way you installed it (webif/tftp...)
downgrade/upgrade to your suggested version should work from the previous recommendation without bricking the device

I know that there are sometimes recommendations for specific devices around, but for me I was unshure what beta version for a (my) device to start with dd-wrt.
Do you think it makes sense to create this topic for starters ?

Recommendations posted:

Do NOT flash r41027 on these devices! If you already flashed this build with GUI issues, do NOT reset to factory settings
revert firmware to the working build you had before r41027 or a recommended version
see as example
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=321282
or
https://forum.dd-wrt.com/phpBB2/viewtopic.php?p=1056400

avoid builds r406xx to r40723 reset button accidental disabled, if GUI reset and telnet does not work you run into problem to reset / nvram erase settings

TP-Link TL-WR940N(D)v3-v6 / TL-WR941N(D)v6
recommendend version r40863

TP-Link TL-MR3420v1
recommended version r39956

TP-Link TL-WR841ND v11
recommended version r40750

TP-Link TL-WR842ND v2
recommended version r40750

Update:

pedrohsk1 reports TL-WR841N v9 with r41218 working.
GUI Apply/Save buttons are "bugged" but work,
GUI Reset unknown, Reset Button working
QoS working
should work on TL-WR841N v10 /v11 same chipset and flash/ram size


more info last working builds here
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=321476&sid=dfd52781762a44a69066326e4e190de0

latest known working build on small flash 4M and 32M RAM devices is r40863 :

tplink_tl-mr3220v1
tplink_tl-wr740nv2
tplink_tl-wr740nv4
tplink_tl-wr841ndv7
tplink_tl-wr841ndv8
tplink_tl-wr841ndv9
tplink_tl-wr841ndv11
tplink_tl-wr940ndv3
tplink_tl-wr940ndv4
tplink_tl-wr940ndv5
tplink_tl-wr940ndv6
tplink_tl-wr941ndv6


possible WOL (WakeOnLan) not included on builds newer than r40439

PS: I added a chip heatsink to the CPU to keep CPU on low temp because TP_link did not apply a heatsink, and the CPU got really warm at install location.

well..low flash memory devices are obsolete..and they are capable to perform, basic stuff only, with very limited capabilities not been able to sustain a modern
WAN speeds...

i haven't seen any positive outputs on the new builds threads regarding those units for an ages....
hmmm, do we know what is your device??....is it supported...at all..???
For all those needs above, you need a more capable device than a low flash size router...

new builds are here

good router's Netgear R6400, R7000, R7800...

if your device is :
tl-mr3420v1 use r39956
tl-wr940ndv6 use r40863
after that build / latest have a problem with webgui that i found. Rolling Eyes

Thank you for quick response.
My intension is to spend a "second live" for those devices with aged/limited manufacturer firmware. Buying new hi end hardware was never a problem and their firmware is supported by the manufacturer for some time. All the todays "good" routers will be low flash memory devices in a few years.

If a quite new device is not working as expected a warranty exchange or a refund is the way to go for me.
I own a TP Link TL-WR941ND v6, that was now replaced by a 5Ghz capable router/access point. Laying around the device was a first choice for visiting the dd-wrt world.
The WR941ND has changeable antenna, more LAN ports than the small repeater with internal antenna it replaces now on the second floor. The performance increased and the WLAN coverage is better. Why put the router into trash ?

TL-WR941ND v6 (2,4 ghz only, 450M WLAN, 32 MB RAM, 4M flash, 4 100M ports) running on build 40863. It's now used for mobile devices and a tv/printer wire connected.
My decision to start with a 39944 build bypassing later builds due to the limited hardware because I could not find a common recommended beta version for this device here. The r40863 seems more RAM memory friendly compared to r39944

Thank you very much. Appreciate your info

The tl-wr941ndv6 has the same CPU TP9343 (750 MHz) 32 M RAM and 4M flash size compared to tl-wr940ndv6. Did you upgrade from older versions and what was the benefit of the r40863 ?

Someone else with a wr940v3-v6/941v6 with dd-wrt with a recommendation ?

Newer build does not mean better/more stable.

nope, there is no such an animal, new builds could be anything...from a stable to a brick...
depends what for ..if its for a repeater or WAP
than any working build will do..dont need to update..

if you are running DNSmasq stuff on an Edge (Gateway) router and ect, than you need to look at the updates in svn first, if your router is concerned to worth updating...

p.s. yep those units are excellent WAP/switch, but nothing else...those few with 700Mhz + CPU can do
a light AP, (Gateway) stuff depend on ISP speed, and
number of client's...
No VPN on those units !!

Appreciate your comment.
No space for VPN on my devices flash and no power on the CPU . WR941NDv6 and similar WR940v3-v6 devices are good for the 50M down/10M or 100M down/40M up vectoring lines as access point or repeater behind the main router.
The user experience of dd-wrt is better if you start into dd-wrt with a known good or a recommended build for a specific device, avoiding latest builds and build related bricks. Do you agree ?

WR941NDv6 and similar WR940v3-v6 are for those
speeds
...this is true...
than, as i said looking for a stable build, its a try'n'err...
do you know, how to recover if it bricks...
than you can try any build...

if you don't read svn and don't follow the threads,
than you relay on someone to be a "kind hearted"..and
tell you "yep this build is stable" ..and than, it turns up, it was stable for his set up, but not for yours...all builds in constant beta stage...

Too much betas to try, so recommendations from other owners of similar devices may help to choose a build to start with ...
