The answer you have received i find it really not pointing to anything as the story which is linekd in there is having tow parts and two cases and none is including Archer C80 eu version .... so thank you but i would rather skip it.

Just got same issue. Tried to upgrade Archer c80 firmware via wireless (using "upgrade" feature in router menu) and now it is not working anymore. Power led is just flashing and that's all. No network is available. After device restart story is the same - power led is blinking, network is not available and nothing changes.

A few weeks ago I got a notification that there was a firmware update available for my Archer A7 AC1750 wireless SOHO router. I stepped through the process and was able to complete the firmware update with no hang-ups. However, once I did this, I now have no access to the Internet through this router.

Every light is green when plugged in, including the Internet light, and I can still connect wireless clients to the router with ease. But I'm getting no actual connection to the outside. I bought this router only 6 months ago and it has been working fine since the update. I have reverted back to the Linksys router that I replaced with this one and I am able to get Internet through that. My connection to the ISP is just through an ethernet line that has been wired through my building, so no modem to reboot. I have tried a factory reset of the device and still nothing.

What confuses me is that the Internet light is solid green, and the Tether app shows that my connection to the Internet is "good" when I diagnose. But Speedtest.net gives me nothing and even the Tether app shortly after I run diagnostics starts to frizz out as it realizes it can't actually get out to the Internet.

Do the factory reset on the router like @ArcherC8 mentioned by holding the reset button for 15 seconds. If that does not work, download the latest firmware (link) from our website and upload it manually via the web browser.

I took the router to a different home network and had the same problems until I rebooted the modem there. Then it worked. I didn't have this capability at my apartment so I contacted my ISP. They were able to see the device going on and offline as I rebooted, but there was still no data passing through. They had to send someone out and he spent a little over an hour here. Eventually he got it up and running again. It involved a factory reset, but even he was stumped as to why my resets didn't work and his did... Thank you for your help as that provided a nice set of troubleshooting steps. I'm even on the new firmware.

@JB12 I finally figured out the problem!! When you update the router (not sure which version this starts but I upgraded to 1.0.14 and this happened), it cuts your password to 15 characters. Meaning, if your password was longer than 15 characters, your new password is the old password up to the 15th character. So no need to make a tp-link account! Just log in with the new 15 character password and change it to whatever you want. You are able to use more characters when you change the password (not sure what the limit is though). That is one odd bug. Hope this helps!

Same exact problem. Looks like a bug in the upgrade. I would advise against upgrading the A7 until a patch is issued. Unfortunately I didn't have a tplink account configured... Time to wipe the configs for me.

Nevermind, just piss poor design. You must have a tp-link account bound to the router after the firmware upgrade. The work around is to create a user ID then log in to the router with it. Once you have done that it will prompt for the router password. This is the same password that was not working.... except now it works but only to bind the password to the tp-link ID. Once your id is bound to the router you can log in again. No need to wipe your config just bad UI design.

I go into the stupid app. I am logged in on my account. No possible password works to interact with the actual router. To my knowledge the only default password there is was for the wifi which I decided to keep. I even tried that and it won't work

I can login on the website version and interact without issue. But I want to be able to use the app. Wish they would acknowledge they bugged the last update and release a new one that fixes this on its own. At least from the website I could DL it.

this will let you in, but when you log out again you will be always required to log in with TPLink CLoud ID. Have you found a way to restore normal access with local password only? Frankly I don't give a s*** of administering my router from a cloud account and I would much prefer to do that only from local network.

I own a Archer C7 bought in the Netherlands at a physical store some 5 years ago (MediaMarkt) and use it succesfully in my home network, also in the Netherlands. Id like to upgrade firmware to stay as secure as possible. Howevers, it starts to puzzle me.

Basically, we don't suggest customers upgrade the device firmware across regions and it will be against the warranty. A wrong firmware upgrade may damage your router or cause the router to not function properly.

Clearly, the picture shown in the PDF doesnt comply with what I see on my product, as posted in my openingspost. So although you suggest to use this firmware, the files itself suggest otherwise. So how should I interpret this?

The hardware version V2 and V2.0 are actually the same hardware, we generally update the package and product label to mark the package or production revision, the number after the period is usually due to a change in the display box or where the device came from.

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?
