Thanks a lot seppe1998
I did restart all. with yhe ipad i forgot network reset network setting and did a hard reboot.
im using a linksys router.
The thing is, everything was working fine for all macs and ipads and iphones(wifi related) for a long time. no
the only change was yesterday when the service provider cut off the service for a few hours. When it got
back on, I had the problem with the ipad 2 and the macbook.
