I assume that the IP address you need to access is 192.168.0.227 and not 22.214.171.124?
Because you have disconnected the PC from your DG834GT router, there is no longer a DHCP server to give your PC's network adapter an IP address. You will therefore need temporarily to give the network adapter a fixed IP address. Go into the Network Connections folder ("Start > Run", type NCPA.CPL and click OK), right click the Local Area Connection and select Properties. Highlight the entry for "Internet Protocol Version 4 (TCP/IPv4)" and click the Properties button.
In the TCP/IP Properties sheet that opens, select "Use the following IP address" and type in...
IP address - 192.168.0.5
Subnet Mask - 255.255.255.0
(Leave the default Gateway address blank)
...and click OK back through all open windows. You should now be able to access the Wireless Access Point's configuration.
To revert to automatic IP addressing, go back into the TCP/IPv4 Properties and set *BOTH* the IP and DNS sections back to getting their addresses automatically.
