The router default has the MTU disabled and that is how it was before I
updated it. Just now I check to enable it and tried several settings. 1492
is the max it would allow and I went down in increments until I was down to
1300 but it was still no go. Anything else I should try? I really cannot
afford to buy a new router at this time.

The error msg is always: "485  Your server has unexpectedly terminated the
connection."
I still could not use  the web-base interface BTW.

A last note, scanning of out going email is disabled in the Norton antivi
settings.., and as always, I do have a very good connection to the internet
otherwise...

Thanks
Vic

  This sounds to me like an MTU setting issue, which might be on the router
itself or on the client computer(s).

  The MTU (Maximum Transmission Unit) size determines how large messages (in
the generic sense, not necessarily email) get broken up into packets.  On
Ethernet devices, it generally is set by default to 1500 bytes.
  There are a few things which can be going on in a network which add
overhead, so that a packet which is of acceptable size for one part of its
journey may turn out to be too large at another point.  There is a process
which is designed to let oversize packets be broken down further into
"fragments", but the design is flawed and so many applications flag their
packets to disallow this.

  The solution is to use smaller packets in the first place.  Find the MTU
settings, and ratchet them down from 1500 (or it's possible that the flash
upgrade set it to something else on the router...) to 1480, or perhaps even
1460.  The loss of efficiency will be negligible, and your packets should
start being able to get through.
