Wireless Does Not Automatically Reconnect Out Of Sleep Mode

I used to have ATT DSL but we recently switched to U-Verse. I have a Trendnet TEW-452BRP 54g wireless router than was handling the PPPoE function. It was set to work flawlessly with my wireless cards. No dropped connections, speed or security issues. It always connected quickly from wake up and on start up. Now we have a 2Wire i38HG wireless router/gateway and it's been difficult to properly set my network up as before. I use the Trendnet behind the 2Wire as my wireless router. Took me a while to figure out what to do, but DHCP is disabled on Trendnet so 2Wire does what it needs to. This option works fine for me. The only problem is that at first my wireless card would not automatically connect to the network through the Trendnet when it is in range like I had it set to do previously. When I would force it to, after 3 times it would magically connect on it's own. I made some changes in the Trendnet (Mainly disabling dynamic DNS and NAT) and that seems to have made a difference. To be honest, I don't know if that is significant or not or if it actually made a longterm difference but it seems like it has. So my problem is now that when I put my laptop to sleep and have it wake up, it does not automatically reconnect. It takes about 2 minutes then it does on its own. I read the event viewer and this is the info it gave me - Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address 0x0018DE0682D8. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

Level - Warning
OpCode - IpLeaseRenewalFailed
Source - Dhcp-Client

Then after 2 minutes -

Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x0018DE0682D8. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

Level - Error
OpCode - IpAddressNotAssigned
Source - Dhcp-Client

After this, it connects by itself. I don't believe I have configured the 2Wire or Trendnet properly, so I need some guidance and suggestions on this matter.

2Wire - 192.168.1.254

- I did not change the IP of the Trendnet and I am not sure if I have to.
