Wireless connection is lost
My wireless has been working ok for one year and has now stopped and I have to go hard wire, how do I go about fault finding the problem?

Re: Wireless connection is lost
I should have added my system is linux mint 81.2 and my Wifi is working ok to my smart phone.
Re: Wireless connection is lost

Anyone please?

Re: Wireless connection is lost
Hello, I have also lost my wifi. I am using Mint 18.3 and yesterday when I booted my laptop (Dell Latitude E6400), I received a dialog box which read, ' Cinnamon has crashed you are now in Fallback mode." I found some help in the forum and I have my desktop back, but still no wifi. There are no wireless options given in the Network Manager.
I searched around the forum and found some advice, entered some code into Terminal and got this:

Re: Wireless connection is lost
Have you updated the kernel? Perhaps try using an older kernel? It seems newer kernels are having problems with Broadcom wireless.
I believe you can switch kernels by pressing Shift while booting (please do correct me if I'm wrong, I'm very new to Linux).

Re: Wireless connection is lost
Thank you. Yes I did recently upgrade the kernel.
I tried holding the shift key at start up 3 times and it didn't open grub.

Re: Wireless connection is lost
Thanks for your help, I replaced the wlan card at cost of £4.00 and the system is back up and running ok.
