Vlan, Tagging HELP,HELP

[jbcom41]

Hi everyone

I have 2 HP switches,  2650 and 2524 with 4 VLANs, the forth one is the one I created on the 2 switches. I have attached a Cisco access point onto the 2650 switch and a Draytek router 2820 with DHCP enabled onto the 2nd switch 2524, the ports are untagged and all other VLANs work ok.

I never setup the other 3 vlans just the 4th VLAN and i cannot ping the Access point from the router or vice visa, can someone please please help me or point me in the correct direction.....

any help would be greatly appreciated..

thanks
