Error 22 message (cant connect to internet)

I have an HR24-100 DVR and Im trying to connect to the internet via my linksys wireless router. After putting in all the info it asks for (IP, subnet mask, default gateway ect, I get the error 22 message. It shows OK status on IP, Subnet, Default Gateway, DNS and Network, however it shows "not connected to the internet (22)". I'm somewhat familiar with networking and can probably stumble my way through this with someones help. Any ideas about what I can do to connect...Im frustrated at this point......thanks in advance!
