Are the v11 builds for TP-Link TL-WR841N also okay for TL-WR841N v11.1, please? And does a later version number in the beta builds a good indication of the most developed/best version to use? Thanks.

Hi,
I've successfully upgraded my TP-Link TL-WR841N Rev.11.1 to 05-19-2016-r29739 and today to 06-02-2016-r29816. Thanks for that!
Unfortunately it did not fix one issue. I've got 2 Routers. One (Vodafone Easybox 904) is configured as DHCP the other (TP-Link with DDWRT) no DHCP.
I've got both connected via LAN Cable. My Laptop is connected to the DDWRT Router.
If the DDWRT Router is OFF, the Laptop gets its IP Address from the DHCP, if I power ON the DDWRT Router the IP-Address is gone. It feels like the DDRWRT Router is blocking the DHCP broadcast..
Second that, ive just flashed a v11.1 with build: 07-01-2016-r30082 and everything went fine that i can see.
Also worth also pointing out like the v7's and v9's ive flashed in the past, you also need the following (below) startup script to enable communication between the lan ports.
Code:
# Fix lan port communication 841 v7, v9, v11
swconfig dev eth0 set enable_vlan 1
swconfig dev eth0 set apply
Finally, not sure if its just mine, but the audible high pitched noise from the 9v psu is awful as the unit boots, it gets a little better once its booted... just a warning to others if your hearing a high pitched noise its probably the psu.
Hopefully its just this unit, as ive configured a boat load of previous tp-link841's of various revisions and this is the first one that's a screamer.
*Update
Just configured two more v11's and they are silent, so i guess i just got a bad PSU last time.
*Update 2 It appears in later builds (i think anything from later 2018) going forward the old startup script no longer works and will cause the router to go dark when it applies, however the lan port bug does still exist. For Current Builds 2019 (and possibly older builds, ive not tested) use the updated script below:
Code:
# Startup Script Fix lan port communication 841 v7, v9, v11 - Version 2
# Ensure WAN port is assigned to switch before applying
swconfig dev eth0 set reset 1
swconfig dev eth0 set enable_vlan 1
swconfig dev eth0 vlan 0 set ports '0 1 2 3 4'
swconfig dev eth0 set apply 1

Hello! Novice here. I installed firmware 06-02-2016-r29816 on my WR841N.v11 with no problems then spent hours trying to ping the two pcs I connected to the ethernet ports and get file sharing to work to no avail. After much googling I found this thread. The code you mention below to fix port communication, how do you use it? Are they telnet commands? I'm not familiar with telnet... is there another post that explains were to put these codes or how to make a startup script? Also should I not have used the US version of the firmware?
Thanks in advance!

Stick it in as a startup script (under admin/commands), then reboot
Also unless you are in the US and have the US version, the answer is no, stick with the non US version of the firmware, flash the US firmware to a non US version of the router will result in a brick.
