>>> Band selection: Auto, 2.4GHz only or 5 GHz only? (Currently Auto.)
Set that to 2.4GHz only as that is the frequency used by 802.11b/g networks.
>>> Band Preference: Any, 2.4GHz over 5GHz, or 5GHz over 2.4GHz (Currently Any)
Set it to 2.4GHz over 5GHz.
>>> Networks to access:
Set that to "Access Point (Infrastructure) networks only".
>>> I also wonder if I would be as well to go ‘hard wired’.
A "wired" network will always be more reliable than a "wireless" one and should be used where possible.
