You can try reintsalling the firmware for the brcm adapter then rebooting. The Linux kernel is not the problem. The wifi is blocked by an on/off mechanical switch.The problem is the Dell BIOS which are accessible to the Apple Iphone and the laptop era Vista/XP. Check the BIOS to make sure the hardware WIFI switch is enabled, and by the way first try turning it off and on again. Also change the boot order if USB is listed ahead of main disk and/or disallow booting or flashing from USB. TC

So I may not be much help here as this situation has not occurred with me despite using LL 3.8 and 5.0 with more than 2 dozen old and even older laptops.However, my suggestion until,someone more knowledgeable replies, is what about picking up a WiFi USB?I have resorted to using these on occasion when the WiFi stops working on some of my student placed laptops. The majority are plug and play, just make sure they are linux compatible, and they are very reasonable cost wise. I haven’t bought one recently, but in Canada they are probably between $10-15 Canadian so converted to USD they might be free (lol )

Yes, the restore point tool is called 'System Restore Utility' and uses a program called Timeshift.Found under Menu-> System->However it only runs on demand (not automatically) so unless you have run it fairly recently it won't help here.

I cannot tell you how often the Wi-Fi of an older model laptop/desktop goes down from plugging in an iPhone
sudo ifconfig yourinterfacename down
sudo iwconfig yourinterfacename mode managed
sudo ifconfig yourinterfacename up
My question is, is there a restore point on Linux lite?
