Help Move Archer C6 on OpenWrt

Hi,

I'm using a TP-Link Archer C6 from 2 weeks in replacement of a Xiaomi Mi Router 3G which is dead due to storm...

But I have issues with wifi.
After around 1 week the 2.4Ghz band is not reachable, not visible... and I should move "Version" from "Auto" to "WPA2-PSK" or return to "Auto" if I'm on "WPA2-PSK" and also move "Encryption" from "Auto" to "AES" or return to "Auto" if I'm on "AES" to have the 2.4Ghz wifi available...

If there is a solution to keep the original firmware I would but if not, is it possible to restore my adress reservations (in "DHCP Server") for all equipments connected on OpenWRT ?

Thank you very much :wink:

I am not sure I understood your question. The C6 is now with stock firmware and you want to install OpenWrt?
And you want to make reservations in dhcp server after you install OpenWrt?

yes exactly but I would to transfer my backup of the original firmware on the new one (openwrt)

sorry for my poor english, i'm french

No you cannot transfer a backup from stock firmware to OpenWrt. You'll need to configure it from scratch.

What does it mean from scratch ?

Cause it's very fastidious to restart from beginning for all equipments...

I have my equipments linked with my domotic solution with fixed ip adresses...

is there a way to do it easily ?

From zero.

You can edit the dhcp file located in /etc/config/dhcp manually either directly with vi (if you are aware of how this editor works), or install a more user friendly editor nano, or you can scp the file and edit it on your desktop with your favorite text editor. You'll need many host instances:

config host
        option mac '00:11:22:33:44:55'
        option dns '1'
        option name 'somename'
        option ip '192.168.1.10'

ok but I can also edit the one of the openwrt to inject all ?

How i can find this file ? from web interface it is possible on original firmware ?

Many thanks for your help :wink:

That is what I explained earlier.

I don't know if you can find that on the original firmware. You could try to take a backup of the configuration and try to view the file as text.

I have tried to open it with text editor but it seems to be encoded...

Bad luck, you'll have to transfer them manually.

ok :cry:

and the openwrt firmware will fix the 2.4GHz issue for archer C6 ?

Also I'm on original firmware 1.3.6, can I flash by using web interface ? (1.3.6 is not listed...)

The only issue I could find is about 5GHz

5GHz WLAN has greatly reduced speed, range and stability as of openwrt 19.07.

You can try to, if it fails downgrade to 1.3.4 and try again.

I have my problems not solved, so I will go on openwrt...

right now 1.3.6 is listed so i can inject the firmware directly in the web interface if I understand ?

It's easy to configure from scratch ?

Have you some tips to give me ?

it will really solve my problems of wifi ?

thank you

edit: also, existing an android app to access with smartphone with 4G ?

I don't own the device, so I cannot say for sure if it will solve your problems.
Read carefully the wiki mentioned above how to flash OpenWrt and be prepared to recover via serial if needed.

Ok where I Can have informations if it solves this problem ?

What do you mean by "recover via serial" ?
If it crashes to restore the original firmware by RJ46?

Search the forum if other users of this router have any idea if this will be solved.

If seems to be solved...

WPA2-PSK and AES should always be chosen as that has the highest security. The other choices are for cases where you must support a very old client device which does not implement WPA2-AES.

If a router doesn't do what it is supposed to do with original firmware, it may have a hardware problem. Installing OpenWrt will not help that. Running the original firmware is the best way to confirm that there is a hardware problem.

Make sure you're using the most recent version of the TP-Link firmware. Upgrading from stock to stock won't affect your settings. If the most recent version still doesn't work, consider sending the router back under the warranty.
