Our Demon broadband service has been good for years, but over the past few weeks it's been really bad. We have had the same wifi router for ages (a D-Link) and it's been reliable, but in recent weeks the ADSL service has cut out completely, three or four times per day.
The wifi is still working (I can communicate from one local computer to another) but the connection to the outside (in either direction) is totally gone, and the "ADSL" light on the router is flashing indicating a problem. I can "solve" the problem by rebooting the router, but rebooting the router three or four times a day is completely impractical and a right pain - and, of course, 100% impossible if I'm away from home and trying to log in remotely.
(I'm actually having problems posting this blog article, since my connection only lasts about two or three minutes at a time this evening. Have rebooted router five times while writing this post. Cor blimey this is a bad service....)
I rang Demon customer service and I could tell I wasn't the only one having the problem - they've recently added a message saying "if you're having broadband problems try rebooting your router before ringing". I see from a recent news article that it is definitely affecting lots of people.
The first thing Demon told me to do was move my router so it was plugged into the main landline socket (not an extension) and try changing the microfilter. So eventually I found the kit for that and did it, but the problems were exactly the same.
Then I rang back, spent another 45 minutes waiting for an answer from the tech support, and after going through the same questions, the only thing they could tell me was "buy a new router". Hmm, so if the problem is that my router is crap, how come everyone's having the exact same problem as me, all at the same time? Everyone's router has broken at once? Not particularly likely. Apparently Demon have done some kind of "upgrade" to their broadband service, the details of which I don't know, but it looks like something might have gone badly wrong with that because lots of people seem to be having the same problem as me - a service that worked perfectly well and pretty much rock-solid for five years is now "upgraded" to a totally awful state.
IF YOU HAVE PROBLEMS: First reboot the router - turn it off, wait 20 seconds, turn it on. If you have the same as me (rebooting fixes it but not for long), try making sure your router is plugged into the primary landline wall socket (with no extension cables), and try changing the microfilter. Tech support will refuse to help you until you do those steps. Then if you ring tech support, they might say that your router must be faulty and try a different one. I certainly don't know of a wifi router I can borrow. But if everyone is having the same problem then it isn't our routers that are at fault but Demon's service.
