Right now there's a known DHCP handshake problem between the SB2 modem and certain routers...most routers work OK.
Make sure you download and install the latest firmware for your router, this solved the problem for some routers, not others.
In the meantime, the easy solution is to log into your router and try one or two Release/Renew DHCP functions...if that does not work, power-cycle your router once or twice, and last thing to do is power-cycle the modem..
Word is they are working on a final solution, which may involve new software on their servers and/or new firmware downloaded to the SB2 modems.
It would help if you contacted them and gave them the model number of your router...they have a team troubleshooting this problem with the different routers that have problems.
