No Wifi Signals Being Detected...Help!
Hi, as you may have already guessed, I am utterly inept when it comes to anything IT-related, so assistance would be appreciated -especially if it's clear and simple.
The problem is as follows:
Earlier today I replaced windows 10 with the latest Linux Mint on my old HP Pavilion laptop. All was smooth and reassuring as I endeavoured to tackle the task alone, but I soon stumbled upon a great problem: no wifi signals were being detected. I used an ethernet cable to install (what i thought was) the necessary driver to fix this problem - Broadcom, I think. However, to my great dismay, it had no effect; the only way to access the internet persists to be the inconvenient ethernet cable.
I apologise in advance as I'm sure the problem is simple and has been unskilfully overlooked - as I mentioned, I am quite poor at dealing with the magic boxes and their many problems.
Any further information I can provide need only be asked for.
Many Thanks.

Re: No Wifi Signals Being Detected...Help!
I would install the Broadcom b43 (Legacy) driver, as the Broadcom STA driver does not work for me on the same wifi card you have.

Re: No Wifi Signals Being Detected...Help!
thank you for the reply. How would I go about doing that?
Re: No Wifi Signals Being Detected...Help!
Go to Menu/Administration/Driver Manager.
OR
1. Run in Terminal:
sudo apt-get purge bcmwl-kernel-source && sudo apt-get install firmware-b43-installer
2. Reboot.
This removes the Broadcom bcmwl-kernel-source drivers (Broadcom 802.11 Linux STA wireless driver source v.6.30.223.271+bdcm-0ubuntu4) & installs the Broadcom firmware-b43-installer drivers.

This is the response to the second command; it doesn't seem right:

Re: No Wifi Signals Being Detected...Help!
Keep using bcmwl-kernel-source as the b43 module doesn't support your wifi but you need to go into UEFI/BIOS settings and turn Secure Boot off
