Pc not getting up address via DHCP
Devices connected to the LAN ports of my modem are not getting IP addresses.
Both it and the devices are set for DHCP.
I've swapped ethernet cables (they all show a connection light and flashing activity light) and reconfigured the router many times and still no good. This is the second model of router I've tried too. It has worked before but had intermittent problems and is now not working at all.
My PC is Win 10. I've tried safe booting, using a static address, all to no avail.
I've noticed there are error messages in the system log saying "No ip addresses to give, OFFER abandoned".

Hi, welcome to our community.
Did your ever try different LAN ports on the router for your computer?
Do you have other wired devices and can they connect the the modem router via Ethernet cable properly?
If possible, if you connect your computer to the other network device via Ethernet cable, does the internet access work?
Did you check the wired adapter in your computer?
Thank you and best regards.

I've tried a couple.

I've connected a laptop and it has the same problem. (it connects fine via Wifi)

I've gone through every setting I can think of in the adapter.
If I do a complete reset of the router and run the config again the PC connects up. But over time it seems like the DHCP pool fills up for some reason and the server thinks its assigned all the addresses so then if the PC resets, or I power it down over night it won't connect and gives declined errors to the DHCP server and I have to reset it again.

Hi, thanks for your further sharing.
After confirmation, it seems that the same issue happened on your several TP-Link DSL modem routers, and the computer keeps dropping IPs sent down from the router according to the system log you shared, it is more suggested to contact the technical support of your computer to confirm.
Best regards.

The PC isn't dropping offered IPs, it sends declines because the address is marked as in use. When I reset the router (thus clearing the address pool) the PC picks up an IP address straight away which clearly indicated the issue isn't with the PC. This happens both on a PC and on a laptop. Different opperating systems and different hardware. And I've never had problems before on non-TPLink modems.
I've also never seen a DHCP server's pool fill up with not actually assigned IP address like this before. I think there's something odd about the TPLink DHCP server implimentation on these routers.
