I have a TL-WR720N wireless router. I was able to connect via my t460s Linux laptop before, but one day it stopped working. Now all of my devices except my laptop can connect to the same AP. Also, I'm not sure if it's a coincidence but my ISP was doing maintenance the day I started not being able to connect via my laptop.
When I connect from other devices, they connect to 10.28.16.1 and get assigned an IP like 10.28.16.* and they all work fine.
The problem laptop connects to 192.168.0.1 and gets an IP like 192.168.0.* it can only connect to the routers admin page.
Please excuse my ignorance in networking, but here are things I have tried/checked:
- My laptop will connect to other networks (like my phone's hotspot) just fine
- Resetting the router, different channels, different SSIDs
- I booted Linux mint from a thumb drive to check if there was a software/configuration issue on the laptop, but even this "fresh install" cannot connect
- I tried spoofing the MAC of my laptop to be a different one
- I checked that the BSSID that my laptop and other devices connect to are the same
Somehow, I still can't access the internet through my laptop. Nothing makes sense anymore! Would appreciate any pointers on how to debug this, or ideas on what it could possibly be.
Update: I can get my phone to connect to the "bad" network occasionally (192.168.0.1) and I can get it back on the good one by doing "renew DHCP"
192.168.0.*
. Also, now I'm pretty certain that the issue is either with the router or the ISP as I can get my phone to sometimes get on the "bad" network on 192.168.0.1 (I can also get it back on the good network by pressing "renew DHCP" on the phone)
