[AFMUG] UPnP question

[Ken Hohhof]

We recently switched a customer over from Frontier and everything is fine 
except printing from his computer to his Lexmark printer over WiFi takes 
forever, it was fine using the Frontier DSL modem for WiFi.  We supplied a 
Mikrotik RB951G-2HnD.  Note that printing isn't just a little bit slow, one 
page takes like 10 minutes.

Everything looks fine in the WiFi stats and changing WiFi parameters has not 
made any difference.  Pinging this device from the Mikrotik, we get higher 
ping times and more variation than other devices, not sure if this is 
related.

Since there does not seem to be a WiFi problem, I'm wondering if it could be 
some higher layer protocol problem, like the fact that we have UPnP disabled 
on the Mikrotik.  Could Lexmark be using UPnP between the computer driver 
and the printer?  If so, would it care if UPnP is enabled on the router?

I really don't understand UPnP, other than to know I don't like it from a 
security standpoint.
