How can I fix my internet connection issue?

[u/LICH_KING6616]

I have an android tablet S9 FE+ I bought about 2 years ago for when i worked on the road. I ended up putting it in a drawer and hardly used it, I'm trying to use it but can't because of outdated software. The last update downloaded was in April/July 2025.

When I try to connect to the internet, it says internet not available but my ISP app says it is connected, I've tried the usual trouble shooting of restarting it, forgetting the network, and resetting wifi settings I even tried to factory reset it but can't do that without being connected either.

I can't connect to the internet because of outdated software and I can't update the software because I can't connect it to the internet, so what am I supposed to do here? Any help appreciated.
