In the last few days I have had a device disconnect itselfs from the BTHub6. Attempts to re-connect the device fails both by using WPS and entering the wireless key. re-booting the device both soft and hard does not resolve the problem. The only way I can resolve this is to re-boot the hub and start again. The device then connects automatically. A few days later is disconnects again. The device is an HP Envy 5546 printer.
(PS: BT have just offered me a deal to upgrade to the latest Hub, have they done soemthing to my current one to get me to take up this offer?)
