broadcomdriversnetworkingwireless
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:

I did what Pilot6 suggested. Here is the output:
vikram@vikram-Inspiron-11-3148:~$ sudo dpkg -i *.deb

Accepted Answer
You need to install wireless driver.
Insert your Ubuntu installation disk or a flash drive and copy these files from the installation disk to your Home directory:
pool/main/d/dkms/dkms_XXXXX.deb
pool/restricted/b/bcmwl/bcmwl-kernel-source_XXXXX.deb
Then run the following in terminal:
sudo dpkg -i *.deb
If you have UEFI BIOS, you need to disable Secure Boot to load the driver.
18.04 update:
The solution won’t work on 18.04, because build-essential and its dependencies are not installed by default. The dpkg command will complain that dependencies are not installed.
You can manually find the required packages on the installation media (“pool” directory sorted by alphabet) and install them the same way as the dkms package. I hope nothing is missing there.
