Absolutely this. I've had a couple of Dell Precision laptops running Ubuntu now and the one with a Broadcom WiFi chip was super frustrating. It's been a couple of years since that one but AFAIR, the connection would go down every 1-1.5 hours and you'd need to reload the relevant kernel module to get it working again. The other two have both had Intel WiFi cards and I've not seen similar issues.
