We have had 5 calls to the techy lot today and they have worked to the end of their standard solution checklist, none of which has made any difference. At call 5 the techy changed the bandwidth of the WiFi channels narrower. Made no difference. I did notice that the WiFi stayed connected even though there was no internet data flow however I could still access the router admin console via WiFi. Most odd.
They have escalated it to their experts..... who are looking at downloading an updated OS to the router sometime tomorrow when we can manage without it for a while.
Ongoing..
