Got a bizarre problem with our Buffalo bridges (Airstation WLI-TX4-G54HP) whereby they no longer link up printers they're bridging to the network and the orange activity LED on the printer doesn't blink (but the green "connection" LED does).

Plugging the bridge into a computer works fine and plugging the printers into the network directly works fine. Same issue on different buffalo bridges and different printers, though the printers with this setup are the HP 2600n - and yes they are naff but this setup has worked fine for years!

Only recent change is the upgrade to ruckus, however the bridges themselves still ping and communicate fine, and as I say link up with desktop PCs without issue so a bit baffling why the printers stopped working!

Any suggestions?
