Internet works fine on Laptop for a minute or two then stops, works fine on other devices

This has to be the weirdest problem that I've ever encountered:

I've got a laptop that works fine on Wifi in different countries and on different ISPs around the world and here in Sweden. But on my home broadband ComHem (the largest ISP in Sweden) internet works for a few minutes then stops. If I disconnect and then reconnect the same happens. A couple of times it has continued to work for an hour or so without a problem, but this is rare. The crazy thing is that all my other devices, work laptop, smartphones, smart TV etc. all work fine all of the time. I also remember that I experienced the same issue with my laptop whilst staying at a friend's place in Sweden who also had ComHem. Any ideas anyone (before I go crazy!)?

p.s. I just updated my virus check and ran a full scan but it didn't find anything.
