Issue with ARRIS TM 822 modem connecting to PFSense box

[Justin_]

I am having issues with using my ARRIS TM822 modem supplied by my ISP to connect to my Dell PowerEdge 860 server running PFSense 2.2.6 64Bit
When I try to setup ports and try to auto detect the WAN link, it wont detect anything. I have tried different servers, PCIe NICs and they are all on the supported hardware list, but it still wont work.
I also am not able to connect to it at 192.168.1.1 (displayed default IP), but that could be just because I haven setup the other ports.

Thanks in advance for any help

Is there the latest firmware image on the modem?
You could try out to connect the modem and your pfSense box to a
small network GB LAN switch to surround or get rid of this issues.
