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.

ISP: RCN https://www.rcn.com/boston/ . They are unhelpful/don't know what's going on. Had my own cable modem, replaced with their ARRIS one, problem continues. Speed is good but connection drops randomly (see logs below where it happened twich in the space of 5 minutes).
Only work around I can think of is to get a static ip but this usually costs extra and I shouldn't have to. Would love to get a real solution. Please let me know if you have any ideas. Thanks!

Hi, which firmware version are you running on the Archer A7 now? This "Teardown and release" issue should have been addressed already, it is suggested to upgrade your router firmware to the latest official version, then confirm.
BTW, who is your ISP, and what is the WAN connection type on the A7, Dynamic IP or PPPoE?

WAN Connection Type: Dynamic

Have you confirmed the modem stability by connecting a computer directly to the modem and test the internet? We hope you could verify this first, then we can investigate further.

@Kevin_Z - Modem connection is stable.
Teardown and release keeps happening every few hours on the router. Here's a snippet from the logs:
5:31 ET
8:38 ET
10:33 ET (3 times)
2021-07-19 22:33:56
2021-07-19 22:33:33
2021-07-19 22:33:24
...
Seems like every couple of hours. Speed test through the wired port on the router degrades before disconnect from 900+MBps to under 300 MBps. No wifi at play here, direct connect by cat5e. Once the DHCP refresh completes, wired speed goes back to normal (above 900 MBps).
Thanks.

@Kevin_Z - I've sent all the informaiton off to support but I was wondering if there is a solution to the problem or if it is in the firmware. I've isolated the problem to the length of the DHCP lease on the IP that is given to by my ISP through their Arris cable modem. My question is, is there a way to set the DHCP IP lease duration time (for the WAN connection) through the Archer A7 administraiton console web interface? It doesn't appear that you can but I wanted to double check. If not, my only options seem to be change ISPs or change my router for another brand that is known to work with the Arris cable modem. Or wait for a firmware update from Tp-link (not a good option). Thanks.

Hi
I have the same issue as author but with TP-Link AX55 with firmware 1.0.6 Build 20211108 rel.61776(4555):
DHCPC INFO [16180] teardown and release
As i see i have the newest firmware as possible.
What can i do with this?
This is definitely not a problem for my internet provider because working earlier on a router with a modem from the operator (now it works as a bridge) everything was ok.

My ISp is big polish provider UPC.
The problem persists.
I noticed that most often there is a heavy load on the connection from my computer (video conference on Microsoft teams for +5 people).
Today, for example, I had a problem with downloading a 2.9GB iso image several times. Several times in the middle of the download there was a problem with the router. I tested it by downloading 2 completely different images from different sources several times.
Finally, I had to connect the laptop directly to the modem (which works in bridge mode) and after the cable I was able to download the mentioned ISO images.
Advice like cable replacement didn't help.

@ArekP If this is the case, please send us the whole system log on the AX55 router when the issue happens, we would like to escalate the case to the support engineers, they will contact you via your registered email later, please check and respond.
BTW, you can install the beta firmware we provided in the following thread to see if it will help:
