No, imagebuilder process starts with a prebuilt kernel that doesn't have the chip id mentioned in the driver that's linked into it.

You need to build the kernel from source, and the rest of the openwrt image from source.

Thanks for the quick answer. I think I was a little bit confused.

160MHz are Wave2 of the ac standard.
I have a Xiaomi MiWiFi Mini with 160 MHz, so I guess at least MediaTek MT7620A has it.
also have it:
Broadcom BCM94709R4366AC
Marvell Avastar 88W8964
MediaTek MT7615 AP Reference Design and MT6632 STA Reference Design
Qualcomm IPQ8065 802.11ac 4-stream Dual-band, Dual-concurrent Router
Quantenna QSR1000 4×4 802.11ac Wave 2 Chipset Family

give me please the next google link, or try to give a better answer....

The problem is that some later firmwares won't let you flash an unsigned firmware due to FCC regulations
Look up how to do flash using tftp in the unbrick section, flash to an older version.

After that, you'll be able to flash from the OEM firmware.

Hi guys,

I was gonna test some stuff with the stock fw, and here's what I'm not sure about - can I safely flash OpenWRT after on the latest Archer C7(EU)_V2_160616 stock firmware?

This is what I'm not sure about. Is it locked down?

Yes. It's locked down and you will not be able to flash any other firmwares, even official.

Hi everyone!
    First i'm quite sorry for my bad English.Now I have a tl-wdr7500 v5. I also have the ttl. We all know that use the original plant ART is  most stable.But I do not have a  programmer(a tool to Write and brush the flash).We can use the TTL to write data to the flash.So how can I use the TTL to backups the original plant ART?

Many thanks,

Hi guys,
I have a Archer C7 AC1750 but V2.1. I try upgrade Openwrt 15.05.1 but it brick
Who have solution for this version?
Tks,

Is it officially labeled as 2.1? You can try trunk which doesn't have web ui or Gargoyle which supposedly have a fix for the later editions of Archer C7 v2.

Yep, it officially labled as 2.1
i try again with trunk version, but i dont see diffirent about file size of Archer C7 15.05.1 vs trunk

If it's finally relabeled it might have bigger modifications from original C7 v2 than the "newer versions" which had a different flash chip afaik. Please post back if either trunk (or LEDE) or Gargoyle work for you. They just as well might not.

Please help, what to do ..

I've bought the TP-Link Archer C7 AC1750 2.0 router.

I followed the installation of OpenWRT procedure from wiki.openwrt.org/toh/tp-link/archer-c5-c7-wdr7500
First I tried to download openwrt-15.05.1-ar71xx-generic-archer-c7-v2-squashfs-factory.bin file but the original firmware did not let me to upgrade. Then I read from the page above that :

That's what I did and downloaded the openwrt-ar71xx-generic-archer-c7-v2-squashfs-sysupgrade.bin file and then updated the router using Ethernet cable. After the reboot, I cannot connect any more to it. The url 192.168.1.1 do not reply. 
I remark that my ip configuration is working my ip is 192.168.1.140 and the ping to  192.168.1.1 works.
Now, what should I do?

Sysupgrade files are only for OpenWrt -> OpenWrt upgrades. Factory images are meant to be flashed when you have e.g. stock firmware or DD-WRT running on your hardware.

I'm a beginner, I tried to download the normal firmware, which do not work, I tried the firmware from the quick start section. wiki.openwrt.org/toh/tp-link/archer-c5-c7-wdr7500
And now nothing works. What should I do now?

If you are always on OpenWRT you can use "sysupgrade" OR "factory" - if not you ahve to use the factory image. Also you have to read and to understand

Hello, everyone!

I own an Archer C7 v2 and I'm have some issues with 5GHz network. I keep having some random  disconnects/reconnects, like if the service is restarting or something. It requires no action from me to have it back when it drops, but it's annoying... happens like 1 time each day/2 days.

Anyone aware of that, and is there a fix for it?

P.S.: 2.4GHz network runs flawlessly.

Thank you in advance.

Cheers!
