I have a Vostro 3300 (tech sheet).
When I first used it I had to install the driver to connect to WiFi.
Having installed Ubuntu Desktop 18.04.4 I believe I no longer have this driver.
I have seen a similar question here about a Vostro 3460 but I couldn't get the solution to work.
If I download the driver from the dell website as before, is there a way for me to install this driver using Ubuntu?
If anyone has further questions I'm happy to answer
Edit:
msk@delete:~$ lspci -nnk | grep 0280 -A3
12:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] (rev 01)
Subsystem: Dell Inspiron M5010 / XPS 8300 [1028:0010]
Kernel driver in use: bcma-pci-bridge
Kernel modules: bcma
Also I think the answer may lie here: https://victorpalau.net/2010/09/09/vostro-3300-and-ubuntu-10-4/
However I am having trouble implementing the solution. However when not using a wired connection I too have noticed that my wirless option seems to have disappeared. I think I'm close.
Edit2:
Here is a full list of what I tried.
