|When you say "wifi modem" are you in fact referring to a "combo unit" that is a modem, router and wireless access point all in one device?|
If so, what is the make/model of said device?
People in that room can jump online via the wifi modem. You can also print to the wireless printer in that room via that wifi modem being local.
How do these people connect to the network? Are they connecting wirelessly, or do they connect via a network cable to the switch?
However, I can no longer print to the wifi printer from anywhere else in my network (I could before I got a new router and wifi modem in there).
How do these people connect to the network? Are they connecting wirelessly, or do they connect via a network cable to the switch? When the people in the other areas were able to print, how did they connect to the network?
Would this be a problem with this Switch or with the modem e.g. can I send a print command through the switch to that modem?
Since it's an unamaged switch, it isn't likely to be causing this problem. It could be the modem but until I know more about the modem it's hard to say what the issue is.
Oh, another thing to include in your next response. On both a machine that can print, and one that can not print, open a command prompt window (ie: Start >> Run >> type cmd and hit Enter) and perform the following command:
Once you've finished, copy/paste the output into a response on here so we can have a look.
For info on how to copy/paste from a command prompt window click on my name above and read my "how-to" guide titled, "Post the output of ipconfig (version 2)"
Please label both accordingly (ie: can print, can not print)
It matters not how straight the gate,
How charged with punishments the scroll,

I am the captain of my soul.
