* I wasn't able to find the "TP Link AP 110 router" specifically. Is this the new equipment that you have? https://www.tp-link.com/us/business-networking/omada-sdn-access-point/eap110-outdoor/
* What's your ISP? Cable, DSL, fiber?
* What's your full setup? ISP modem => Old Linksys => EAP110?
* Hypothesis 1: IP assignment between the ISP and the EAP110. You're connecting your modem directly to the EAP. The EAP isn't a router itself, but an Access Point. It does try to get an IP assigned from the modem, but doesn't work well. I would put the old router between the modem and the EAP110 and see what happens.
* Hypothesis 2: Power issues. Looking at the [documentation](https://static.tp-link.com/upload/manual/2022/202203/20220307/1910013169-EAP110_UG.pdf), when running on PoE, you need to run the EAP110 off of a PoE switch. I'm guessing while the EAP does get some power from what it is currently hooked into, it isn't enough for stable operation. Try connecting the EAP110 to a stable power source and see what happens.
Have you considered placing a second access point where you actually want to use the internet and running a cable to it?
Wifi signals are unpredictable and the results will vary with every parameter that changes... Device connecting, orientation, location, weather, foliage,
Geez, I'm a more than a little bit worried. No security settings and no passwords? Is that for downstream connections or is it for your administrator functions for the router?
My understanding is that the home router is the sitting duck of the Internet. Easy prey for anyone on the planet, for whatever purposes they desire.
Pardon me if I have misunderstood.
