[solved] Wireless working, but signal so weak. realtek modem

Post by bakamono353 »

Um. I'm relatively new to these forums or rather I haven't used them in ages, so forgive me if I miss anything. The wireless is working quite fine, but when I updated from Linux mint 18 to 19.3 the wireless signal of the Realtek modem dropped drastically making it hard to connect and stay connected. It stays at 36% for the most part. Please, any help would be great.

Thank you HAWR and Jeremey, everything was solved and I didn't realize that there is an issue with realtek hp wireless modems. Both of you have been greatly helpful. The signal is back to where it use to be.

It is because HP got cheap and only used one antenna wire rather than 2
