Hello FurryNutz,
it is done - mean:
single mode N(band 2,4 GHz N) and WPA2 and manual channel 13, set these only on my router.
Unfortunately I do not have an AES in the router menu so let AP the menu called mode(another possibilites are station infrastructure, AP bridge point to point, AP bridge point to multi point, AP bridge WDS, universal repeater)
Still disconnecting/connecting, sometimes after while only disconnecting, green led blinking.
Thank you for another opinion,
Jiri
