I have an Epson printer that was connected to the network via the AP30.
Now it cannot connect, fails authentication. So I created a ssid with a lower authentication level, but the printer still fails to keep an association. The laptops and i-phones work fine.
Also the signal strength appears to have dropped after the upgrade. The printer is about 2 metres away from the AP30 and the connection speed is about 500k to 1mb. The speeds to the i-phones and laptops also appears to have been reduced.
