Hi everybody, I just installed Ubuntu 16.04 on my laptop, and the Wi-Fi is not working.
Specifically, the WiFi signal seems to be weak, since in Settings->Network all the Wi-Fi networks are indicated as "out of range" (my version is actually in italian, so I'm translating....) , but I have a dual boot and in Windows10 everything works perfectly.
I looked on the forum, and I saw that some people with my network adapter (RTL8723BE PCIe Wireless Network Adapter) had the same problem and were suggested to update the drivers...however, I thought it might be better to run the Wi-Fi-info script, and ask for your sugestion before doing anything
Thanks in advance!
