Help with 'Error code: 37' on PPC6700

[outdoorplant]

When ever I get on line with my PPC6700 I get this error msg:

Error code: 37
Miscellaneous erroneously mobile IP set up Occurred

I still get on line ok and everything seems to work ok but this happens every time. Any idea on how I can fix this? I checked the basic connection settings and they all look ok.
