I have installed Ubuntu alongside Windows 8.1. But the wifi is not working in Ubuntu (perhaps the drivers are not present), which worked fine in windows. Also I cant connect with Ethernet since my laptop does not have an Ethernet port. So is there any way for me to connect to the internet in ubuntu?
Edit: Output of the terminal command
lspci -knn | grep Net -A2:
vikram@vikram-Inspiron-11-3148:~$ lspci -knn | grep Net -A2 01:00.0 Network controller : Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01) Subsystem: Dell Device [1028:0018] Kernel driver in use: bcma-pci-bridge vikram@vikram-Inspiron-11-3148:~$
I did what Pilot6 suggested. Here is the output:
