Question: What version(s) DD-WRT works long term stable on WR841n-v9 for router, without having to reboot daily or weekly?
I have 3 ver.9s on r33006 since Aug.6. At one point I had 17 days uptime on all 3 without a single rx or tx error or crash or reboot till weather related power outages ruined my record. Even then they always come back up without an issue. I would say that is pretty stable.

Thanks. I used the version that you suggested.
Wifi speed and range are identical to stock/factory; and, that's good news.
Reliability testing (dns/vpn) indicates a routing quality improvement with DD-WRT. A+

Tomorrow, the TL-841n v9 on dd-wrt 33006 is at 1/3rd month. Glorious in the short haul is typical of Atheros, so I'll update after more time has gone by.
Do you have auto channel by chance? I have fixed channel and I do not have these issues. I had devices connected for over a week and the connection has not dropped.

no, it's fixed channel for mine as well. I also bumped my tx power to 21dbm. Does anyone fiddle with the tx power? Would this cause wifi drops? What is recommended tx power?
The funny thing is, to fix it I don't even have to reboot the router, I can actually go into the admin settings page and click "apply" down at the bottom and it comes back up. Weird.
When it does drop, my devices show authentication error though. So the radio signal is not dropping completely, just the devices are having difficulty either authenticating or obtaining IP address. _________________ TP-Link TL-WR841ND v9

I am using a TPLink WR841N v9.0 with OpenWrt,
OpenWrt Chaos Calmer 15.05 / LuCI (git-15.248.30277-3836b45)
Kernel version 3.18.20
and it works fine. Turned on and used for months without problems.
Is this the same as ddwrt? If not, am I missing something by NOT having the ddwrt?
I just don't understand this enough to know what I am doing. Thanks for the patience.

For power: A tall shelf, a favorable location, and a wifi survey for least crowded channel
On the wireless page:
Wireless Network Mode, Mixed
Channel Width, Full 20mhz (most reliable)
Wireless Channel, (Not auto--do a wifi survey)
Advanced Settings, Check the box
Regulatory Domain, New Zealand
TX Power, 33dbm (auto-limited by reg domain)
Antenna Gain, 0dbi (reduction amount is zero)
Noise Immunity, Enable
Short preamble, Disable
WMM Support, Enable
Airtime Fairness, Disable
On the services page: The radio buttons for Dnsmasq, No DNS Rebind, Query DNS in Strict Order, are Enable. All of the other radio (round) buttons on the services page are set to Disable.
On the Nat/QoS page, UPNP Tab, Disable
On the administration page:
802.1x, disable
TCP congestion control, Westwood
TCP timeout 600
UDP timeout 60
Notes: A MacBook Air and similar barely compatible clients will fault the Atheros wifi driver (requiring a reboot) if set to 20/40 or HT40; so, set to HT20 to fix (wifi connection speed will show 144, but real usable throughput will probably increase).

I am not using the 33006 anymore but the router stayed on 21 days on that version and I have never had memory issues. Currently I am using 33555 and the available memory is about 40% all the time. Probably depends on the used features too.

Thanks for answer.
Thus you can recommend 33555 for WR841ND v9?
If you want to be protected then this needs to be enabled (on). There could be devices that have issues to connect but it was not may case... all my devices connected without problems.
