I'm seeing a lot of new motherboards with built in WiFi nowadays, and I am wondering why you'd use this as opposed to the wifi built into your modem / router?  The router (I have n HG630B) is always powered up, so the house has WiFi regardless of whether 'my' desktop is running, so the house has 24/7 internet.  I'm guessing that the motherboard WEiFi might be of a higher spec, but I don't know what devices could take advantage of that.

It feels like forever since I decided to update my five year old 3930k system, but it is running reasonably well — especially after having to reinstall Windows recently — and I don't feel like rushing untill X299 / X399 i9X / Threadripper has settled down.  I mean it was only this week that Threadripper bootable raid 0 with NVMe drives became available.  I'm leaning towards Threadripper 1920X (because it seems to be the best choice for Photoshop which is 90% od what I use my systems for), but I don't have a clear idea of which motherboard to use, and whether I should go with onboar WiFi.

[EDIT]  I have just thought that I also run a Linksys RE6500 wireless range extender, and how would this complicate things?  The bottom line, as I see it, is that it would unacceptible to need my desktop to be running for the rest of the house to have internet, so what would be the point of a motherboard wireless?
