Trouble with WiFi on laptop :intermittently turns off and must reboot; but now won't come on at all

Hi @Gary1 ,
AFAIK from this post your card is supported by the linux kernel.
en:users:drivers:iwlwifi [Linux Wireless]
You could see that in the section 802.11bgn products at the end of the page.

I also provide a link to the Arch Wiki page where you can read how to try configure your card whether the signal is poor, disabling the n wireless band.
'Network configuration/Wireless - ArchWiki

At last, you can also search the forum in order to try to solve the problem. For example, this post is old but it could help you to find more posts like this.
