1. Will the internet LED on the Archer C80/C64 change to orange/red when the issue happens?
 - Yes

 

2. Who is your ISP? What is the model of the ISP-provided modem? Do you have stable internet connectivity if you connect a computer directly to the modem? This needs to be tested and verified for the same period when you observed the disconnect on the C80/C64.
- The internet connectivity is stable when device is connected directly to the modem
 

3. If the ISP-provided modem gives you a pretty stable connection, please try with a new Cat5e or Cat6 Ethernet cable between the modem and the C80/C64 to observe if it will make a difference.
- New cable, the same results (I want to clarify that there were no any issues before Oct-Nov, I think, as I'm using the router about a year now, with the same devices connected from the first day.)

4. If nothing helps, please save the whole system log on the C80/C64 and send it to support.forum@tp-link.com for further investigation.

- sent

@Georgi681 Thank you very much. 

Email received and has been forwarded to our support engineers for further analysis.

This is good, but first complains about this issue is from 2 years ago. 
Why 2 years are not enough to find and resolve the issue with TP_Link routers? 

Every user is asked to follow the troubleshooting procedure, but with so many complains it is obvious the problem is not in the user configuration/connected devices, but something in the firmware probably.

"TP_link" was first brand name which came into your mind when say "router", but now, with these continuous problems, as many before me, I will look around for router which is NOT TP-Link. As one of the users wrote - we are working, and it is not only annoying to disconnect from a meeting or in the middle of something important.

 

Today I experienced at least 4 drops during the day.

@Georgi681 Thank you again for following up and sorry for confirming the details.

However, without those details, our engineers may not be able to analyze the issue, as it may be hard to determine if the issue was caused by the router itself or by the environment. And there could be a lot of factors that may cause the issue you are reporting, and that's why we want to understand more about how do you use the router.

Please don't worry, our engineers will try their best to help work it out. Please continue working with them directly via email and update the solution with the community.

Looks that this is "standard " issue on TP link devices. My Archer C80is doing the same. Drops for few seconds... anoying and useless.  I have a bounch on new C80 and C6 devices.. Bought short ago  (2x C80, 2x C6). Thinking to throw them away.

I am using standard MAC tables (no masking, etc) it happens on all devices as the Router is dropping everything hang on it....

-So it is not for specific client

-it is not for private or randomezed MAC

 

I am using ISP provider on the optic .. Previous Dlink worked well, but I replaced it because of Dlink was getting old.. But what a mistake. Archer C80 is new but very disappointing. It drops my network at least 200 times a day. Watching TV.. stops suddenly, listening radio drops suddenly, having a video conference drops me out suddenly...

I would expect fast firmware updates to solve this issue.

Hi @BojanO, except for the logs, can you please confirm some more details as below?

1. Will the internet LED on the Archer C80/C6 change to orange/red when the issue happens?

2. Who is your ISP? What is the model of the ISP-provided modem? Do you have stable internet connectivity if you connect a computer directly to the modem? This needs to be tested and verified for the same period when you observed the disconnect on the C80/C6.

3. If the ISP-provided modem gives you a pretty stable connection, please try with a new Cat5e or Cat6 Ethernet cable between the modem and the C80/C6 to observe if it will make a difference.

4. If nothing helps, please save the whole system log on the C80/C6 and send it to support.forum@tp-link.com for further investigation.
