Losing WAN connection on ERL 1.4.1

I seem to be intermitently losing my WAN connection after upgrading to firmware ERL firmware 1.4.1.  I reset ERL to factory settings and configured the WAN + 2 LANs using the new wizard.  My WAN port eth1 is set to DHCP so it should be picking up all IP information from my ISP, which it looks like it does.  It takes awhile for it to connect but it does connect.  However, intermittantly the connection will drop and looking at the logs it seems like the connection starts to fail because the ERL eth1 broadcast addr is set to a subnet.  I'm using charter cable service and I had no issues with the previous firmware.  I have the charter tech coming out tomorrow but I wanted to see if anyone has run into this before.

From the error logs (I * out my ip):

Re: Losing WAN connection on ERL 1.4.1

Looks like you are being passed the wrong subnet from your ISP.  If you only get 1 useable IP from your ISP then the broadcast address should be 255.255.255.255 or /32 (not /23)

turned out to be a bad crimp and ground wire was causing a lot of noise.  Thanks everyone for the help.
