This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hello. So the past few days I started randomly getting connection drops so I decided to check my router logs and noticed that whenever the outages occurred, "tear down and release" is the first thing to show up. Specifically it says,"[7029] teardown and release " and right above it at the same time I also see "[7029] send dhcp release ip xxx.xxx.xxx.xxx". The "dhcp ip release" log has a warning label which makes me nervous. I found these forums from this post when searching about this issue: https://community.tp-link.com/en/home/forum/topic/216024.
I have the same hardware and same issue but there was no solution posted. Unlike that poster, I'm hesitant to put my logs up exposing my ip unless In missing something. Anyways any help would be appreciated. Thanks for reading.

Hello, as we can confirm that the "Teardown and Release" issue should have been addressed already, and it is suggested to upgrade your router firmware to the latest official version, then confirm.
Download link for the latest firmware:
Archer A7_V5: https://www.tp-link.com/support/download/archer-a7/#Firmware
Archer C7_V5: https://www.tp-link.com/support/download/archer-c7/#Firmware
If any of you still encounters the "Teardown and Release" issue, please confirm some basic information as below:
1. Who is your ISP, and what is the WAN connection type on the A7/C7, Dynamic IP or PPPoE?
2. Check and ensure the internet line or ISP modem is stable, bypassing the TP-Link router. Connect the PC directly to the ISP modem (or internet cable from wall), test and monitor the internet connectivity, ensure you have a stable connection. Check this guide for more suggestions: [Troubleshooting] Router Disconnects from Internet.

Hi
I have the exactly the same problem
It was working fine - I had a new Archer V6 Router V2. I upgraded to 1.3.6 Build 20200902 rel.65591 and ever since exactly every 8 mins and 8 sec later I see a normal log of tear down and release log , followed by warning of "Send dhcp release ip x.y.z.a". My internet disconnects for 5-10 secs and come back
Since it is every 8min8sec every time, i am wondering the cause.
1. I have tried the options suggested in other links viz, cloning the mac address, nat-boost disable, changing dns to 8.8.8.8 ( currently its ISP provided one) -without any success
2. I am about to reverse to previous version but looking at the this message wonder how it could solve.
3. Wonder if factory reset would help - as this router is only 2 months old and this is first upgrade I did ( or any config change I did )
My ISP visited and confirmed that there is no issue on his side.
Please help

Judging by your statement :
"It was working fine - I had a new Archer V6 Router V2. I upgraded to 1.3.6 Build 20200902 rel.65591 and ever since ..."
and "... as this router is only 2 months old and this is first upgrade I did ( or any config change I did ) "
is logical to try :
"2. I am about to reverse to previous version but looking at the this message wonder how it could solve. "
Here's how you can do that.

Thanks, but when i tried to revert to earlier version it shows "Invalid File type " during upgrade. Ofcourse I unziped the file
I downloaded the file from https://www.tp-link.com/in/support/download/archer-c6/v2/#Firmware
I tried different versions - but the result is same. Any thread that you can point to ?
Btw, I tried, factory reset, dns change... Wondering how there be no solution to this ?
Where can I see a configuration of 490 sec ( exactly the teardown and dhcp happens )

Hi
1. I downgraded to 1.3.4, 1.3.1(Beta), 1.3.0. successfully.. The issue still persists. Every 8 min, 8 sec tthere is drop in the network for 5s.
a. I downloaded from other static.tp-link sites, not from the download link from from my country ( In) - which doesn't work - Gives 'invalid file type". I hope this doesn't invalidate my warranty ( I did eu version - as in my product box )
2. After each of the downgrade did a factory reset - still no fix
( All the firmware update was done from web interface of tplink, and confirmed post flash that the version reflects )
I don't know when this bug was introduced, 1.3.0 release notes says it had fixed the intermittent router disconnect but it doesn't look like
Can anyone please help ? My previous Datalink router doesn't give this issue. All the results are measured by ping-plotter.
1. How to find out which version can fix my issue ?
a. Is there anyway to find out which firmware version ( and corresponding file location ) came with my product purchase ?
2. Any one can point to version 1.2.1 location ( for EU & V2 ) - which some people say its very stable
a. can you confirm if i can downgrade from 1.3.0 - cause the release notes says I can't
Archer C6, V2
Thanks

@Sathish_in did you ever get this fixed for you?
I have had the same problem the entire time I've owned my Archer A7. I even had their remote tech support try a bunch of different things on my router via a remote screen share debugging session for about three hours. Even they couldn't figure it out.
I'm wondering what ISP you have? Maybe it's some weird compatibility issue?

@Murkyforce Exactly the same problem with RCN to my TP-Link AC1700/Archer A7. Any resolution on this?
