Are  you using dhcpcd  on a  'Potato' box  ?  Can  you purge  the dhcpcd
package and instead, install dhcp-client ?


> seems to have something to do with dhcpcd

dhcpcd never worked  for me and another thing which you  have to note is
that the  modem at your  end has already  acquired an IP from  the cable
server  head.   In your  case,  dhcpcd is  not  getting  the dynamic  IP
assigned to your cable modem or  maybe it is your stock kernel which has
to be blamed in not letting thru a certain packet.


> went back to a fixed IP address, removed DHCP, and it worked

Please do note that dhcpcd and dhcp-client are two different packages.
Another thing is that, please insert the CONFIG_FILTER module for debian
stock kernels from one of the kernel image debs.  If you are brewing
your own kernels, then compile in CONFIG_FILTER under 'Networking'
options.  You would also like to read under the kernel source tree, the
following note 'Documentation/networking/filter.txt'.

I could never get dhcp-client to acquire the IP from my cable modem if I
disabled this option while compiling my kernel.  So watch out and read
docs related to this....YMMV.

I have observed  no speed differences between OSes;  maybe M$ would have
negotiated  a  secret deal  wherein  the  modem  manufacturer would  have
embedded a secret layer which communicates with Win 9x better, Hehe ;-)
