[Solution] Fixed the internet unstable connection issue with my Archer C6
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I just bought an Archer C6. In the first week, it works fine and I'm satisfied with its performance and Wi-Fi range. I would say it's perfect at this price. But the situation becomes worse after one week. I found that the router will drop the internet connection every few days. I have to reboot it to get the internet back. It's very UNACCEPTABLE. I have to say it's a disaster for me when I’m playing games.
I check the router when this issue occurs, the LED turns red; I try the diagnose tools provided on the router, I cannot get a reply when I ping google.com.
I have called my Internet provided to check my line because I think it's their fault. No luck, the man from my ISP has come to my home and checked the line quality, the modem is OK and stable. He said it's the router and I should call tplink. Then I have to call tplink for help. Troubleshooting is not helpful after I talk with the first agent. He asked me to check the LED status, change DNS, reset router... Finally, the agent said he can do nothing to help me and I have to fight with their senior engineers. I decided to give them a last chance because I think this router is worth saving if they can fix my issue. The senior engineer asked for a remote assistant because they want to check my issue quickly. OK, that's what I want. He used a tool named Wireshark to capture some data and told me will contact me again.
Luckily, two days later, he came back to me and gave me a beta firmware. After testing the beta firmware for more than a month, the router remains working fine. The senior engineer is efficient and technical. I'm very happy about their service.
This is the explanation from the senior engineer, for who may get help from my case:
"We have found that the lease time of your IP address is 5 minutes, which means every 2.5 minutes the router will renew its IP address. The router may lose connection after frequent DHCP renew. This is a small probability event. However, renew time is too short and frequent, which makes it possible. We have fixed your issue with beta firmware. The official firmware will be ready in the future."
This is my story with this router. Thank you for your help, tplink.

@DeLiYocoo I'm probably having the same problem with my Archer C6 v2
Here is video of the issue.
It seems like it's working for couple of seconds, then it loses connection. I can load first 10 sec of YouTube video or first few of FB posts, but then it's so slow.
I have latest Firmware and I tried to restore to factory defaults several times. Sometimes it works and sometimes everyone at the same time is having this problem. Wired and 5GHz connected devices are working fine all the time.
Has anyone solved this problem for good?

@DeLiYocoo thank so much for the info. I brought brand new AX6, every other day it requires renew from ISP, how stupid? Firmware is updated, now we all have to ask that senior engineer for beta firmware? Hello TP head?

I am facing the same issue with the same model. I tried to contact the tech guys through their helpline number but the call never got connected to any engineer. I have just sent them an email regarding the same. Hope to get this issue resolved soon.

has anyone been able to solve these problems with the C6 router? I have disconnections from the 2,4 and 5 network. Speed drops in both networks and I also have the problem of duplicate networks where a "hidden network" appears. It is the fourth time that I reset the factory. MY version is v2 US and there is no current firmware.

This is the only firmware that has been stable so far. I would recommend anyone to try this one (source: https://community.tp-link.com/en/home/forum/topic/208968)
I have always been able to revert back to this particular BETA firmware and it has been worked nicely ever since I first tried it.
I've tried the very latest and the versions in between... No luck!
1.3.5 (latest) had instant problems with intermittent disconnects when pinging sites.
Really stupid situation where stable firmware is unusable! It's been months!
i had installed this beta firmware for a few weeks now. the wifi signal strength may drop down to 1 bar randomly but it does not disconnect.
For 2.4Ghz wifi, i set the channel width to 20Mhz. For 5Ghz wifi, i set the channel width to 40Mhz.
