Topic: TP-Link TL-WR841N v11: looking for testers for trunk build

The content of this topic has been archived between 8 Apr 2018 and 7 May 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

I have patched support for the v11 into trunk but would need some testers since I do not have the hardware myself.

Images (both 15.05.1 and trunk) can be found here.

I had reports of the TP-Link web interface refusing the image so please try flashing to TFTP and report back to me. There might be a firmware lock in place in the TP-Link web interface.

If the site does not resolve, please try another DNS provider like OpenDNS or Google's DNS servers.

Everyone is of course welcome to test but you need to be able to fall back to TFTP if things go wrong.

Your feedback is welcome!

Edit: since v11 support has been upstreamed, I am now only providing a 15.05.1 image. You can pull the trunk build from OpenWrt's official snapshots.

I'll try to test your images on monday, 28.03, but how v11 differ from v10, except flash chip? Few days ago I successfully flashed TL-WR841N v11 with v10 image (via sysupgrade -F /tmp/xxx-sysupgrade.bin). Regards

Thanks! From what I gathered there shouldn't be any more differences besides the model version embedded in the firmware header. It wouldn't be the first router where a manufacturer bumps the revision number over minor differences, 'breaking' the image check in OpenWrt.

In fact, what you did with -F is exactly that: skipping the image check. You're knowledgeable enough to be aware there shouldn't be any technical hurdles in using a v10 image on a v11, but the average user is not.

Forcing sysupgrade or modifying the headers are workarounds till proper support is implemented; these images were built from an OpenWrt tree with proper support smile. It will be upstreamed once I get confirmation it is indeed working.

Edit: It looks like the firmware works but I'd need confirmation that the image can be flashed from a TP-Link firmware.

Would you mind reverting back to the original firmware and then trying to install my build through TFTP?

Yes, I can confirm that both images are quite stable - 15.05.1 (without issues, except nonexistent source "http://volatilesystems.org/dl/openwrt/c … /packages/" in /etc/opkg/distfeeds.con) and trunk (some issues: default access to shell for "root" without any password is granted, some minor issues in luci - also noticed in other trunk images)
In case of installing factory image 15.05.1 via tp-link web interface it is important to rename image file (use shorter name, e.g. tl-wr841-v11-factory.bin) - no need to use TFTP.
Wi-fi signal level and coverage are good, comparable to original firmware, system and kernel logs - without an errors. Do you need any other information? Thanks

No that's plenty of information thank you smile.

The opkg sources are leftovers from my own builds, you'll notice the 15.05.1 has the last LTS kernel as well. You should be able to replace the links with the regular OpenWrt ones.

I have sent in patches for inclusion in both trunk and Chaos Calmer 15.05.1.

Thanks for helping out!

Support was added in trunk today.

Great work! Thank you for your efforts

I have seen that wikidevi entry as well, I think it's incorrect. People have reported the v11 to be almost identical to the v10, and that one is 4/32. Also, my images have been confirmed working, so...

I think someone messed up over there smile.

I had success flashing 15.05 from stock through TP-Link web interface, thanks for this.

Happy to help out smile.

Hello,

Completely new to OpenWRT so here are a couple of newbie questions.

I've just acquired a V11 this morning.

Tried to look for v11 image in the official trunk and it was not there.

Downloaded v10 thinking maybe it would work, while using the web interface. It throws me an error saying "Please choose a file to upgrade" even tho i choose the .bin file i downloaded.

Next step i attempted was trying to look for specific v11 image and came to this forum post, however the link provided by OP does not work anymore.

I would really appreciate any assistance.
Thanks,

The image *is* present in the OpenWrt snapshots, I just verified this again. You should look closer.

Thanks for the answer. Indeed it is, i apologize for the foolishness.
Used wiki link which led me to https://downloads.openwrt.org/chaos_cal … x/generic/ where v11 is not present.

So i just used the web interface and it gladly accepted the image v11, however, after rebooting 192.168.1.1 is not accessible, saying the site cannot be reached. I looked up some guides on the internet, tried changing my network address to 192.168.1.2 to no avail.

What am i missing?

Edit: Just reinstalled the openwrt imagine via TFTPD, still getting the same "The site cannot be reached".

Trunk images do not contain Luci. You need to install it manually.

Can i add Luci to the v11 image somehow and use the TP-Link web interface?

Edit: On a second thought, if i cant even deal with this, OpenWRT is probably not for me and i'll just use something tiny bit more noob friendly.

Was able to go back to original firmware without any troubles.

Thanks for the answers!

Well, for what it's worth, the stable 15.05.1 image I provide in the very first post of this topic does include LuCI wink. There's no reason to run trunk if you're new to OpenWrt.

Hello friend,

I just got myself a TP-Link WR841N v11. I'm completely new to OpenWRT, so do I just :

1. Download this file : https://volatilesystems.org/dl/openwrt/ … actory.bin OP posted.
2. Access the stock TP-Link firmware GUI.
3. Go to firmware update and use this .bin.

Am I right?

After successful upgrade, do I need to do a 30/30/30 reset like DD-WRT?

This site can’t be reached

volatilesystems.org’s server DNS address could not be found.
DNS_PROBE_FINISHED_NXDOMAIN

That's what i get when i try to access the link.

your dns should resolve volatilesystems.org to 81.11.200.53

nslookup volatilesystems.org 208.67.222.222
Server:  resolver1.opendns.com
Address:  208.67.222.222

Non-authoritative answer:

nslookup volatilesystems.org 208.67.220.220

Address:  208.67.220.220

Non-authoritative answer:

try to use opendns ( https://use.opendns.com/ ) as a temporary solution to allow you to access the webpage.

i have no issues with https://volatilesystems.org/dl/openwrt/ … r841n-v11/

for some reasons google dns fails to resolve it. (i use my isp dns, opendns and google dns.)

nslookup volatilesystems.org 8.8.8.8
Server:  google-public-dns-a.google.com
Address:  8.8.8.8

*** google-public-dns-a.google.com can't find volatilesystems.org: Server failed


nslookup volatilesystems.org 8.8.4.4
Server:  google-public-dns-b.google.com
Address:  8.8.4.4

*** google-public-dns-b.google.com can't find volatilesystems.org: Server failed

You are, but the GUI might complain about the image name, so rename it to something like tplink.bin if it does that. You not need, under any circumstances, that 30/30/30 reset.

Borromini, I was able to upload the 15.05.1 firmware from your site with only having to rename the file. It doesn't appear that LuCI is installed... I checked /etc/init.d and the uhttpd service is not there. Should I follow this guide to install it? - https://wiki.openwrt.org/doc/howto/luci.essentials

Borromini, I was able to upgrade to OpenWRT from TP-Link stock firmware using your .bin file. However it does not have LuCi installed like you said. This is the .bin file I download from your site :

https://volatilesystems.org/dl/openwrt/ … actory.bin

So I tried to install LuCi by myself, however when I tried

opkg update

It gave me this error :

root@OpenWrt:~# opkg update

When I tried

/etc/opkg.conf

, it gave me

Permission denied

error

Any idea why? Can I just download the LuCi from official OpenWRT site instead of your site?

Sorry was away on holiday.

I have rebuilt the images, they should be fine now (and include LuCI). Should also point to the OpenWrt repos now.

Let me know if there's anything amiss.

Do I have to revert back to stock firmware and reflash it back to OpenWRT? Appreciate if you could give me step by step instruction.
