I have an HP laptop with these specs:

System Information
        Manufacturer: HP
        Product Name: HP Notebook
        Version: Type1ProductConfigId
        Family: 103C_5335KV G=N L=CON B=H

And I just installed Ubuntu 17.10 but the internet isn't working, either wireless or wired. Also, I have the following network specs:

hira@palebluedot:~$ sudo lshw -C network

Interestingly, the only internet that is working is a hotspot created via my cellular connection. The Wifi connection is sometimes not recognized (i.e it does not appear in the list of networks), sometimes recognized and connected but excruciatingly slow, and sometimes, recognized but not connected at all. Could anyone please help with this? I've tried upgrading my system as some solutions suggested but that isn't working. Also, note that it may not be a Ubuntu 17.10 problem because I was having the same issue with Ubuntu 16.04.3 and other Debian-derived versions (Linux Mint). Could anyone please help me with this?

    The sanest thing is usually the ethernet cable, before you try anything wifi. Plug it in. Does the network manager tell you anything? What about ifconfig, does it list an eth* with defined ip4v address? If so, what do you get from route -n? – Harald Dec 27 '17 at 13:03
  • @Harald Thanks for the response! I just found the solution over here. Apparently, the Linux drivers cannot detect which particular antenna my RTL8723be Wireless Adapter is using. – QPTR Jan 01 '18 at 19:39
