Internet connection ok...but no internet
Hello.
Just had a week without internet. A rather curious fault developed last Tuesday - suddenly lost the net on my desktop (wired connection to my BTHomehub 2). Also couldn't get the net on my mobile, or any other wireless device either. Landline working fine, Homehub indicator lights and administrator page showing Broadband connection good, and Internet connection OK. Restarted Homehub. No change. Reset Homehub to default config. No change, Swapped Homehub for my old Netgear wireless modem, still the same problem - Broadband and Internet lights showing OK, but no internet! Swapped Netgear modem for my very old BT Voyager (wired connection only) - lights again showed Bb and Internet OK, but still couldn't connect to the net with any device.
Finally took deep breath and phoned BT callcentre. Won't go into it, but despite eventually agreeing that the fault must be at the exchange, said they'd have to send me a new Homehub before they could get their engineers to check the line.
Got new Homehub today, but before I'd taken it out of the box for the pointless swap, the internet started working again via my original Homehub. I guess BT must have looked into it anyway, and fixed it.
Anyone any idea what could make all my modems/routers think there are working Broadband and internet connections when there aren't?
