It could be similar to the issue that hit the world this week where Google Chromecast and Cast-enabled TVs and other devices were sending hundreds of thousands of extra packets and causing routers to crash.
The best thing to do in situations like this is to go to the manufacturer that made it and get all the updates for every endpoint you can. Also, typically you would want to avoid going to the wireless card manufacturer (like Broadcom or Qualcom) and instead
go to your computer manufacturer (Dell, Acer, HP, Asus, Toshiba, whatever). The computer assembler will usually have the better driver for your model, a better site to find/download it, and better support. And while you're there you can get the other updates/drivers/firmware/BIOS
updates.
Do not use the "Windows driver update" tool, as it won't find the drivers that your manufacturer gives unless that manufacturer happens to participate in the Microsoft Windows Hardware Quality Labs (WHQL) certification process, which most don't bother.
So yes you'll see "you have the latest driver" even if that's false. PC manufacturer is where it's at.
You'd also need to repeat this for the router's firmware too -- even if only one computer has the issue, the firmware compatibility between both ends must be up to date to resolve all known/discovered issues. Unless your case is truly absolutely unique,
the odds are that other people have encountered the same problem and that updates are available to fix it. Be prepared to test it on another wifi network too, just to test if there is a difference. Another router, or take it to a friend's house
or coffee shop.
If it still doesn't work, contact the manufacturer that made it (HP). They have to warrant that it will work, one way or another.
