There is no option under wifi to 'change settings'.
However under 'change adaptor options', I have under wireless network properties ticked 'look for other wireless networks whilst connected to this network' and 'connect even if network is not broadcasting it's name (SSID)'.
Having switched on the billion router this morning laptop is not picking up wifi signal, despite being next to leptop, so no interferance. Seems to suggest that depsite WLAN being lit on panel of router, no wifi signal is being transmitted, or at least my laptop cannot see it, but as noted above I can't pick up the router on my andriod phone either.
It may be there is a fault with router.

The SSIDS for the 2.4 and 5Ghz networks are different, 2.4 is 'Billion-AP-2.4g' and 5 is 'Billion-AP-5g'. How would I know if laptop is capable of supporting 5g? I have tried turning off 5g on router but network still not showing. Wireless is set to UK in router set up.
A further thought, in set up details I am asked to go to 'local area connection' via 'change adaptor settings' under network connections. I don't have a local area connection, only an ethernet to billion router, or wifi currently connected to my netgear router. Under local area connection I am asked to check boxes against 'Internet Protocol Version 4 (TCP/IPv4)' and 'Internet Protocol
Version 6 (TCP/IPv6)' and in both cases check boxes for automatic detection of IPv and DNS addresses. These are all ticked etc in both ethernet and wifi properties. Perhaps not having a local area network is the problem?
