Is it just dropping on wifi connections or do ethernet cable connected devices also drop out regularly.
As well as the “check service,” weblink there is also a Service Status number 0800 561 0061 which usually tells you of local issues, down to postcode level (that might even not yet be listed on the Service Status web page) that may give you more info. If nothing shows there call it in and see what they say when they test your connection and if possible get a fault reference number.
-------------------- Services: HD TV on VIP (+ Sky Sports & Movies & BT sport), x3 V6 boxes (1 wired 2 WiFi,) SH2 in modem mode with Airport Extreme Router. On VIVID200, Talk Anytime Phone, x2 Mobile SIM only iPhones.
Service status page shows no known issues in my area for broadband.
I have tried the online test tool numerous times sometimes it comes back with "Check your cables are connected & powered on" and other times it comes back with "we cannot find a problem"
I can confirm that when this happens the solid purple light goes off on the superhub3 (running in modem mode) and you get the flashing green light /arrows and will eventually come back on to the solid purple light.
