Just upgraded to 1GB

All

Thanks for reading - just upgraded from 250 "blast pro" to 1GB and getting less then 100MBs directly conntect to my cable modem - my cable modem is a Netgear CM1100. Rebooted and facotry reset. Comcast chat have pushed a new bootfile.

What is strange the upload *is* much faster (40MBs) but the download speed just seems capped at 100MBs for some reason.

Power levels and everything looks in range - Comcast technican is coming out on Sunday but it just seems a mystery why download has just dropped below my previous Internet package. Can only assume signal loss somewhere? Any idea or things to try?

Thanks
