Your router would be suspect here, have you updated its firmware as a possible solution? The router can be the issue even if other OS's are working fine. And I would update your WiFi drivers on the computers.
Try actually updating your driver :
Make a Restore Point : Start - type in --> Restore find at top and click on it - then Create
Right Click Start Button - Device Manager - Network - write down make and model of Wifi - double click on it - driver's tab - write down version - click Update Driver (may not do anything as MS is far behind certifying drivers). Then Right Click on Wifi Device and UNINSTALL - Reboot - this will refresh the driver stack.
Then check the System/Motherboard Maker's Site and that of the actual device maker (such as Intel, RealTek, Broadcom, or Atheros) for even newer drivers.
Manually look at manufacturer's sites for drivers - and Device Maker's sites.

Download - SAVE - go to where you put it - Right Click - RUN AS ADMIN.
You can download several at once however reboot after you install each one.
After looking at the System Maker's you can check Device Maker's for even newer versions. (The ones from System maker become your fallbacks).
