I have a PHS (and CTR - now configured for WDS with the PHS).

The CTR has the ethernet port and is more flexible (can go MBB to ethernet or use it as the WAN to wired broadband with failover, and others).

The PHS is nearly the exact size of the N810 but thicker (without the power cord or modem attached).

Would you mind mentioning the MBB provider that you are using?
