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

@everclear 

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

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.

Thanks. We have reported the issue to the support engineers, they will likely reach out to you via email to continue to troubleshoot your issue.

@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.
