Having issues with Wi-Fi on LL 3.8 when previously never having issues

Hi Vera,

Regarding the WiFi issue, it may in your case be either a hardware problem or a bug that has crept into your LL set-up, rather than the kernel version itself ...

I say this because we have LL3.8 with the WiFi running smoothly on three laptops with the kernel 4.4.0-140-generic (see summary in signature below), and also my sister's WiFi is fine with LL3.8 and the same kernel on her Toshiba A300 (7 years old).

You seemed to have invested a significant amount of time in setting up LL3.8 on your machine, so understandably you're reluctant to replace it in a hurry, and I think it would be unwise to do so.  My advice, for what it's worth, is to keep your existing setup and instead install, either as a dual-boot or a virtual machine, another copy of LL3.8, 4.2 or another distro, to check the WiFi. Another solution, which might be simpler (if you don't like dual-booting or setting up VMs) might be to install LL3.8 or 4.2 on any spare HDDs and test these on your machine.  Either way, you get to keep your original precious set-up ... 

Cheers
Mike
