100 is my PC. 111 is my Phone. Both are permanent. 5, 3 and 4 are other devices like Chromebooks and phones, these are not permanent leases..
On my PC when this happens I lose internet and every packet sent trying to ping the local gateway is lost. On my Android device, every time the router does the OFFER/ACK cycle I lose internet connection or the ability to log in at the router, despite the WiFi connection being intact. For Android, the solution is to disable and enable the WiFi function in order to regain access until the next OFFER/ACK cycle. On PC, I have yet to find a solution.
This problem occurred recently for PC, and while thinking it was the QoS being the culprit, I just went ahead and factory reset the router. Everything was fine for a day or so before the issues started showing up again.
This happens regardless if a device has a static local IP or dynamic. I don't understand why the router is running ACK/OFFER on permanent leased IPs, but it does. I don't understand why the host name isn't found either.
It appears this problem gets worse as time goes by, the router more often runs these commands and over the next 3 weeks I expect to have to factory reset again. I've done a lot of digging but every article/forum post pertaining to these symptoms either has no responses or the solution is to install DD-WRT on the router. Now I really like TP-LINK's GUI, much better than that of DD-WRT. But if that's the only way I can get a reliable DHCP server, then I will install it.
I'm hoping someone here has had a similar issue, or knows what causes these symptoms so that I can continue using this GUI.

@Kensei No luck unfortunately. Still sitting here occasionally dropping internet for no reason.Found it only happens when i'm using particular devices on the network through. Not sure if that'll help anyone else diagnose the problem
@krisminime What exact devices will cause the issue? What are the OS versions of them?

I have the exact same problem. Wired devices dont have connectivity and work sporadically after reboot. Same error. WiFi is fine.
Latest firmware on Archer C80.

@Kensei
Did you get any answer or advice from TP-Link support?
I see a lot of people have this problem and "solution" is buying new router ?
As I can see there is beta firmware 1.12.1 but I don't know if this problem is resolved?
@Kevin_Z , can you give us more information if this problem is known and if it is been resolved in mentioned beta firmware?

Hello Techies,
From last 3 days I am struggling with network drop issue on “TP-Link Archer C80”.
There are errors in the log which you need to consider,
- DHCPS Lease hostname not found
- inetd select error abort
The main problem is, router is not able to find the hostname of a device which is connected to your router. Any single device having this hostname issue can drop your network or I would say crash your inetd service.
Login to TP-Link admin portal -> Network Map -> Clients
Go to the above path and check if you have changed the “Device Info” of any device.
I had changed the device info to identify the devices, but it requires either “hostname” of the device or “Unknown” tag.
If you change the “Device Info” router will not able to pick the hostname and it will through you hostname not found error and inetd service will crash.
Solution:
If you have changed the “Device Info” for any of the connected device, change it again to its hostname or “Unknown”.
To check the hostname of windows or linux device:
Open CMD/shell and type command “hostname”, copy this hostname and update in clients.
Please check the screenshot below,

My router is working fine now, but my android TV is not working on router.
Other android devices worked with "Unknown" tag.
Let me know if it works for you.
Regards,
Priyesh Manwatkar.

@Georgi681 As per the firmware release notes, there is no mention of this fix, but I would still suggest you install it on your router to observe if the issue gets resolved:
Early Release Firmware Adding EasyMesh Ethernet Backhaul for Archer C80/C64/A8
Please let me know if it helps.

Just an update:
Go to :
Advanced -> Security -> IP & MAP Binding
Check the "Binding List"
Remove all devices from "Binding List", It is creating IP conflict.
It resolved my Android TV Issue.

@Kevin_Z
I've tried this but it doesn't help.
Also the solution proposed by the previous user (change Device Info back to "Unknown") doesn't work and I got these drops everyday.

Hey @Georgi681
Got to the Advanced -> System -> Firmware Update
Under Online Update, check the “Hardware Version”
Hardware Version: Archer C80 1.0
In my case it is 1.0
Now download the latest firmware from tp-link site for your hardware version,
https://www.tp-link.com/us/support/download/archer-c80/
Now, Go to the
Advanced -> System -> Backup & Restore
Under “Factory Default Restore”
Click on the:
Restore all the configuration settings to their default values.
FACTORY RESTORE
After “Factory Restore” it will ask you for the firmware, if it doesn’t ask
Go to Advanced -> System -> Firmware Update
Under “Local Update”:
Browse the firmware file and click on the “Update”.
Now go to the Advanced -> Security -> IP & MAC Binding
Under “Binding List”
Remove all the devices.
Done.
Try this and let us know.

to me this is happening for more than one year now and still no solution..,it happens only if both 2Ghz and 5Ghz Wifi are on at the same time..I did not have this wih 5Ghz Wifi only..
It happens if I put my laptop at sleep..if I open it again there is no way to connect to that wifi back again!.. or if I go out of wifi reach with my IOS phone when I get back no more wifi connection..only if I reboot the Archer..
the only workaround which works if I set a daily reboot on the router..
