14.10 Wifi worked fine, then became slow, now stopped working altogether

It is a Lenovo Ideapad yoga 2 13'', intel core i5, 8gb ram, 256gb ssd,
wireless card is intel 7260
The laptop came with win 8.1preinstalled. I got rid of it by booting from a ubuntu 14.10 usb device and installing 14.10 as my sole os.
All that happened on Friday and Saturday last week. It all worked fabulously.
Since Monday afternoon I've been having problems, though. At first the wifi speed dropped very noticably. Then it stopped connecting altogether.
The situation now is this:
Wifi is trying to connect to my router (which is visible, correct key entered etc.) but can't establish connection.
The laptop does not have a hardwired ethernet connection. So I'm doing this via my desktop mac. This is also why the diagnostics I ran according to your "how to" - well, I don't know what they are worth now.
Router works fine with other wireless devices in the house (internet radio set, google tablet)
Ran ubuntu from the bootable usb and the same problem there.
Initiated installation from bootable stick and the same problem there. Didn't go through with a complete new installation because the problem seemes to me to lie elsewhere.
Seem to have hit a dead end.
Oh, and I really don't know that much about computers. It's just that I so much enjoyed working with it on my old laptop. Never used Windows in the last 18 months or so...
I hope someone can help me. Thanks a lot
Steffen
