I have another HiDPI laptop with the same wireless card (Intel 7260). I don't think your router is the problem, I'm experiencing the same issues. When I'm not in the same room as the router signal used to drop 50% of the time. Few driver updates later things are much better, but it still freezes sometimes. Consider disabling the power saving options - it does help. It seems Intel totally botched it with this card as the Internet is littered with people complaining about it, including Windows users. It seems the Windows drivers have it covered now, but the Linux ones are still catching up.

Regarding the HiDPI - Chrome is the only thing that doesn't play, but since I'm a Firefox user, that's not a problem. Gnome 3 handles it quite well. Yes, some apps (i.e. Skype) get their font rendering a bit wrong, but otherwise it's fine. But the crisp fonts are something I'm not giving up.

For posterity's sake... I kept having bad issues with the wifi. The problem seemed to get worse after the computer went to sleep. It would take websites a long time to load and drop out completely sometimes. I ended up getting a new router since I saw on a couple of forums that it helped. Specifically I got a Linksys WRT AC1900. The problems so far seem to have been resolved. Websites load quickly and no cut-outs so far.

That's exactly what I was seeing. If I take the laptop out of the room with the router I start instantly having trouble. Just being one room away, sometimes I can't connect at all.

Even sitting right next to the router, my bars aren't full which is really strange.

I'll try fiddling with the power saving options. Thanks for the advice.
