I hope have correctly written question, but for clarity I will explain the situation.
At the moment there are 7 computers which number a few months there will be more and each wi-fi adapter + wired Internet ( BUT NOT ALL), there is also a high-performance printer having only the usb standard also has wi-fi.
At the moment the situation is this - all computers are connected via wi-fi in home group, one of the computers the printer is connected, printing is done via Wi-Fi. These are the crutches.
The problem is that often disconnects from the Internet, the Internet becomes impossible, IT says that the Wi-Fi adapters and they should be removed, but then there will be a need for more printers.
The question is, is it possible to make a wi-fi network was used exclusively for a bunch of computers printer? To the problem with the cutting out from the Internet came to naught, and that it is impossible to work.
Oh, I hope wrote more or less clear. I would really appreciate your help!
