What is the simplest way to install a new KMA product on a wireless network, as KMA has dropped their wireless interface? Any feedback would be helpful.

With a wireless bridge.

Look for a product like this. You don't see many in local brick-n-mortar stores, cut can find them readily online. All the usual wi-fi adapter manufacturers also make these.

D-Link wireless bridge on Amazon

I agree, wireless bridges are the way to go. I used to use these to connect scan systems to wireless networks back when scanners were on separate NICs. Actually it's probably easier/faster to set up than the IB-22s were.

I have 3 fs-4000's hooked up via USB wireless print servers.

For machines with separate scan/print nic's I used to get a Buffalo bridge that had a four port switch built in.

i recently using this ethernet converter by Buffalo Technology. Easy to setup and it has 4 RJ45 connection. You can use it for any devices that needs network and internet connectivity.
