WiFi won't start automatically on hub1 without switching off and on in tablet settings

[#1]

When my tablet has been in sleep mode it will not connect to the WiFi on the hub1 router without switch the WiFi off and on again in the tablet settings. This only started since I got the hub1 the tablet worked fine on the old ADSL. Not a game stopper but frustrating. Anyone any ideas?

Try checking your wifi card settings:-

Try googling for "BT Home Hub 5 Type A" and add the make and model of your tablet. More likely to find the answer as the Hub One is a HH5 Type A in a new case and the HH5 has been around for years so has more information available..
