Wireless is working with notebook but not with smartphone

[freak1548]

Hi all,

I hope anyone can hlep me withthis strange behavior.
I installed pfSense (new version) on an alix 2d13 board

3-Interfaces - WAN/DMZ/LAN
WAN - connected to a DrayTek Vigor 130 - VDSL2/ADSL2+ Modem
DMZ - connected to an access point (TP-Link TL-WA901ND, 300Mbps Wireless N Access Point)
LAN - connected to a cisco switch

I can connect (got an IP address) with every device to the wifi but only can access the internet or local server with a notebook.
For notebooks the wifi is working perfect but not for smartphones or tablets.
These devices got an IP address but can't access the internet.

I hope I could explain the problem well. If you need more information, please ask.

Thanks a lot for your support.

I remember having a similar problem when I first setup my wireless, the internet wouldn't work on my kindle and a few other things but it did work on my laptop and iphone. I switched the wireless channel and everything worked.
