At my wit's end.

Here's some context to my problem:

I'm working as a teacher in South Korea. I was moved into an apartment. I was going to inherit the room of the person that I was replacing. I had visited his room before. In this building, the Ethernet cable in the room apparently doesn't work plugged into a computer. He had a router instead that provided excellent WiFi. I noticed that he could connect to his router with his iPhone and with his Macbook Pro. I couldn't connect, however, with my Asus gaming laptop, or my android phone. I have no idea why, but I couldn't.

I moved into his room when he left. I assumed the earlier problem was a router issue. I did a factory reset on the router. I still couldn't connect.

Here is my situation:

- I have full bars on both my laptop and my android phone.
- My laptop says that I have internet access.
- My android has an exclamation point on the WiFi symbol. I apparently have limited phone access, but I have not had limited access on my laptop.
- I can connect to 5g and 2g networks, I'm positive - I do it at work.
- I have tried netsh commands. I have tried power plan changes. I DO NOT have proxy servers enabled at all.
-Turning off Windows Firewall does nothing.
- I do not have an antivirus currently. I removed Norton last year, and I removed everything with the Norton Removal tool.
- I had McAfee at one point, which I uninstalled.
- Malwarebytes detects nothing.

- I have literally no idea what to do. Please, for the love of humanity, somebody help me :(
