Model: Archer C24  
Hardware Version: V1
Firmware Version: 1.10.0 Build 210830 Rel.72007n(4555)

Hello! Bought a new router - Archer C24.
Everything is fine, but every 1.45 hour (105 minutes) the internet crashes for a few seconds, which is enough to mess up all the web applications I'm working in.
What I figured out:

 

1) It's probably not a wi-fi issue: the PC connected to the router by cable is affected too

2) The cables and ISP are fine: my old previous tp-link router works good with current cables, problems started with new router

3) The problem most likely is settings or firmware (though I'm not sure)

 

What I've tried:

1) Changing the router: it helped, so the router is probably the cause

2) Updating firmware: the newest one didn't fix the problem (I even consider downgrading to some old version, tbh)

3) Resetting router settings to default: no help
3) Changing DNS IPs and setting up a DDNS: as you will see from the logs, there are some DNS-related errors, but that didn't help

4) Cloning previous MAC-Address: no help
5) Putting correct values to DHCP: no help

6) Manually setting local IPs of the devices: no help

Overall I tweaked most of the settings, none of that fixed the problem. But that 105-minutes interval makes me think it's not a hardware, but a software problem.

Here are the screenshots of the settings and logs.

Thanks for your help! It looks like the problem appearing with the new router is a coincidence.

The problem was on the ISP side: each time I got my IP lease ended by the ISP, the connection was cut for 3 seconds. Contacting the ISP support has solved the issue. 
The router works fine and I'm glad the issue got resolved.

Thanks again, I hope my case will help someone who stumbles upon similar problems!

Try 1440 for the lease time. It is 24 hours and see if that changes the problem?

When the internet crashes, is the internet LED on the C24 orange or still green? 

 

Who is your ISP? If the old router connects to the ISP modem stably, you can try to clone its MAC address to the C24 to determine if that helps. This is the guide to do the MAC clone on the C24.

The light is green all the way, the PC won't show any "No internet" either, it's just every application or game disconnects when the "crash" happens.

My ISP is "Volia" (Ukraine, volia dot com).
I tried cloning MACs of the old router, current router, PC MAC, but the problem persists.
Every 105 minutes (strictly) this log occurs in "System log"
