Model: Archer C7  
Hardware Version: V4
Firmware Version: 1.0.8 Build 20190411 rel.65590(4555)

Not long ago my router found a new firmware and I decided to upgrade it. I was on the "Archer C7(EU)_V4_180425" firmware and the new one is "Archer C7(EU)_V4_190411" it's one version higher than the last. The upgrade went well, the router rebooted at the end of the process (as it should) and everything is working so far. The only problem is, that the Internet indicator LED - which was green before - has became yellow. In the routers main menu it says that my Internet connection is weak. Beside this I have an IP address, the internet connection is working fine (just measured 650/300 Mbps), WiFi devices also can connect to the router, etc... I've double checked the cables connecting the router to the modem, even used a brand new 1m long Cat5e cable between the two, but the yellow light is still there. Tried to power cycle both the modem and the router several times, but no change. I think it's not normal and I'm sure something is with the new firmware. What should I do know? Is it possible to downgrade the firmware to the older version? Will there be a newer firmware to this router that maybe fixes this problem?

Hello, sorry for missing this issue reporting.

 

As far as I know, the newer version 1.0.8 Build 20190411 rel.65590(4555) has improved the internet detection mechanism, the router will try to connect to the NTP servers and DNS servers on the internet to ensure your connection is good. As per the issue you both reported, it seems that the detection may not be always successful and that's why it gives you an error "connection is weak".

 

It is suggested to change the WAN DNS server on the C7 to 8.8.8.8 and 8.8.4.4, then reboot it and confirm again.

 

May it help.

We've managed to solve this issue.

I've used Google's DNS addresses on both of IPv4 and IPv6. The IPv4 is working fine but the IPv6 is not. So we changed the following setting in the routers menu:

Advanced -> IPv6 -> Advanced -> check "Get dynamically from ISP"

After this, the "Poor network" message disappeared, it's says "Connected" now, and the Internet LED turned from orange to green. TP-Link Cloud is workind now as it should and the Firmware upgrade can also reach the Internet.

 

Thank you for your help!

@agpoli Yeah, that's what I'm thinking, to restore to original settings...

@agpoli So I reset to the original settings and it works. And when I check in the router settings for new firmware, it says it's up to date. So the firmware that I downloaded before and "upgraded" must have been wrong I guess...

No, it was the right firmware, you router will find it eventually. Mine did too, but I won't upgrade again. Maybe if another firmware pops up I will give it a try.

@Kevin_Z 

That's Google's free DNS addresses, I'm using those from day 1. Also tried Cloudflare DNS addresses but the issue still exists.

@Kevin_Z 

 

I've got the email and replyed, also sent a screenshot and the system log. Hope it helps.

 

Another thing I found out that with the latest firmware (with the "Poor network." message) TP-Link Cloud doesn't work. It says "Oops.. The device is offline. Please check the WAN and network configuration to make sure the appropriate settings are entered correctly." Well, my device is online for sure, I have Internet connection that's where I'm sending this message now.

Also the Firmware Upgrade menu is showing an error now when I click on the "Check for upgrade" button, it says "No Internet connection".

 

I will stay on the latest firmware for now, maybe you need to check it via remote desktop.

 

Thanks for your help, hope we could solve this issue.
