  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.
