Hi Otto Yes we have too iPads and a iMac connected to this Wifi and all works fine.
But asAs an up-dateupdate I contacted Samsung, as the tablet is in warranty, and they told me that the only solution is to take the tablet into their repair centre in the city. As it needs to be flashed with new firmware.
Having done that, they have now told me that the tablet requires some parts as there is an issue with this model. Unsure what parts are needed but will post a reply once iI collect the tablet and get the repair report from samsungSamsung. There is notno damage to the tablet as it is only 8 weeks old
