No WiFi - LL 4.2 UEFI

This probably won't apply, but it may possible to replace the laptop's internal wifi card (inexpensively). I just learned about this a couple weeks ago. My 5-6 year old Toshiba C55B has an older Atheros wifi that supports wireless-N in name only (it connects, but doesn't have the full speed). It's a m.2 card in the laptop, like the SSD cards in newer laptops (but, not as long, more square). I thought wifi was a chipset soldered onto the board. They probably were sometime in the past. But, in recent years they are socketed.

If you google about it, there are people replacing them. You could buy whatever's considered the most Linux friendly (Intel or Atheros?). But, it's more confusing than just connecting a wireless USB adapter. If your card has only one antenna (like mine), you have to get the right kind of card. I read about some people buying a second antenna and routing it around the motherboard -- which is better than no antenna at all, but maybe not as good as routing it up into the edge of the display (which would be a lot of work). Some laptop makers (HP, I think I was reading about) "whitelist" wireless cards. A new one might not work.

I just googled and saw this photo of the OP's motherboard:

The wifi card is in the top-left. It has two antennas too! (The specs say it's wireless AC, so you'd expect two.). I'd be replacing that in a heartbeat. There would still be a risk of the bios rejecting a different card.

I just wanted to mention this option in case the OP has an adventurous spirit. If so, the best way to proceed would be googling about people replacing that particular card (in other laptops, etc. Whether Lenovo whitelists cards, etc. It can be time consuming trying to sort it out. But, a replacement card isn't too expensive. $20-$30 USD.).

EDIT: I was googling and saw someone say HP & Lenovo are the only laptop makers who whitelist wifi cards. I also saw this thread on Lenovo which might help you find a whitelisted card. Sorry if I'm going too far into this topic than you're interested. Maybe it would help someone else who finds this in the future. Especially upgrading an older card.
