I have my ISP's router in bridge mode, functioning only as a Wi-Fi repeater, since the OpenWRT device I use doesn't have antennas. However, the internet on the Wi-Fi devices isn't working as it should. There are sudden disconnections and some pages fail to load.
On the face of it, this doesn't really appear to be an issue that is related to or can be solved by OpenWrt.
What happens with ethernet connected devices (that connect directly to your OpenWrt router)? Do those work as expected?
They are working normally. However, should I create a Wi-Fi interface for the devices, or is that irrelevant?
If your goal is to have the wifi devices on the same subnet as your wired lan devices, there's no need to make another interface.
At this point, you should probably reach out to the ISP to get help with their router such that you can properly configure it for (or troubleshoot) use as a bridged AP.
Just as a reference, this is the bridged-AP wiki article for OpenWrt. Your ISP router is obviously different, but the conceptual framework you'll want to use for implementation is the same.
One thing I've noticed is that if I connect the ISP's router to a port other than eth0 on the OpenWRT, the Wi-Fi devices appear in OpenWRT. However, if I connect to eth0, they don't appear. Do you know why this is?
I was researching and saw that for it to work, I need to connect the ISP's router to a port other than eth0, which is the WAN port, since it's now just an access point. Is that correct?
At this point, I don't know what hardware you are using (and thus the port assignments/functions), nor have I seen a config to be able to say for sure.
I'd need more information about the specific connections you are making (i.e. port x on ISP router to port y on the OpenWrt router).
However, my guess is that you've got your ISP router configured incorrectly relative to the bridged-AP mode that you should ideally have, or you have an incorrect physical topology.
Can you elaborate more?
I had replied to you, but some nosy person removed my post just because I used something I asked AI about. I hope it wasn't you.
It was me who removed it. We have a firm rule about AI because it is so often wrong (and, in fact, it gave you questionable advice, and we need to ensure that this doesn't mislead other users and/or feed more bad AI advice). Please see the community guidelines about this issue.

Let's get more details about your topology so that we can better understand what you've got happening.
- What type of internet connection is delivered to your home -- is it cable/DSL/fiber/cellular or is it just an Ethernet connection (found in some apartments/dorms, etc. where the building provides connectivity)?
- Assuming cable/DSL/fiber/cellular, Do you have a separate modem/ONT for the connection, or is that integrated into your ISP router (in this scenario, you'd be required to use your ISP router in some form).
- What is connected to the wan port of your router (where does the cable come from)?
- What is your OpenWrt device and version (using ssh, what does
ubus call system boardshow) - How does the ISP router connect to your OpenWrt router (which port is used on each device)?
I've already solved it.
