Every three months or so my BT broadband starts to play up. Regular as clockwork! It starts with the Broadband light on my router going out and failing to re-establish even with the usual unplug and wait thirty seconds routine, plug into the master socket etc. This has started to happen again, December 2010, following BT Broadband providing me with a new Home hub to replace my Voyager 2500 last August 2010 when it all went haywire last time. Late August, September, October, and November have all been fine and I have enjoyed ' a top class fixed Broadband from BT at the astounding speed of just under 1Mbps being on the end of a long line part made up of aluminium cable!!!
The strange thing is, that whilst nothing obvious seems to persuade either the old Voyager 2500 or the new Home Hub to 'connect', during one of these 'off' periods, if I pick up the phone and make a telephone call, the router 'pops back in' almost inevitably and will stay 'in' for a few minutes after the call is ended. This symptom seems to go right over the heads of BT India who have had their UK colleagues call at my home on a number of occasions, found my internal home installation to be beyond reproach and gone away and done clever things with their own equipment, which seems to give me the next three months free of hassle.
Now as a retired electrical (power) engineer I suspect that somewhere outside of my home there are joints that during the three month 'interregnum' between faults, are quietly getting re-corroded until they become an effective insulator to the BB signal but the increased current flow occasioned by making a telephone call breaks down the 'high resistance' fault allowing a current flow once more, so giving me back my broadband for a short while. If I'm wrong in this can someone please come up with an alternative scenario I can put to BT in the hope that we can break out of the annoying three monthly cycle of repeated faults.
