uc540 wireless conection problems

Hi

I have a uc540 with the newest firmware.

I have configured a wireless network with an own vlan. This wireless is only mobile devices like iphone and so on.

But if I try to open the app store or the webpage www.wdr.de it doesn't work. Pages like google.de or web.de works fine.

I have changed the wireless vlan to vlan 1 the default datavlan than i works.

The only different thing is that in the datavlan has an own windows dns server.

I also have configured on the uc an dhcp area for the wireless network for the dns server I out in the 8.8.8.8, 8.8.4.4 an I tried other open dns servers but nothing helps.

I thnak you in advance for youre help

You need to have 'ip tcp mss-adjust 1452" on either Dialer or BVI interface.

Firewall is useless, you can disable it completely.
