      Re: Rein issue

      The problem is that if the engineer comes during a relatively quiet period, he may find nothing wrong. Keep your router stats graphs to show him. A REIN trained engineer will be able to get more from these than a common or garden engineer.

      i am pleased to announce that the REIN issue has been resolved it was a faulty PSU in another block of flats across the road i am now getting 7meg stable maybe a little more with tweaking
      so anyone reading this in the future and having a rein problem keep on at BT dont accept ''thats all we can do'' or ''we will cap your line'' rubbish

      thanks to all the support guys also big thanks to gord

      Re: Rein issue

      Yay - glad to hear you're sorted - PSUs can be a huge problem, they are plugged into the mains so the mains wiring becomes a large antenna for the noise, running loops around the buildings :/

      Some PSUs are definitely better than others, for quietness at radio frequency noise it's hard to beat an old-fashioned big transformer and linear regulator. In the last two decades they have been replaced by switch-mode power supplies that can save power (and therefore reduce heat) and me more compact but are prone to making a lot of noise. They often affect upstream noise in the case of ADSL, especially affecting annex-M lines. That's because many of them switch at around 80-300kHz.
      If the manufacturers don't pay attention to the PCB design or components they can feed a large amount of noise into the wiring. They don't radiate so much from their own DC wire unless it's plugged into some device that also has a large extent of wiring connected to the DC chassis. That's because low frequencies require very long antennas to be effective radiators, though even short lengths can lead to annoying interference if there isn't much separation.

      There's always the chance that whoever owns the device will wait a few days then plug it back in, so keep your eye on it for it re-occurring lol. You can sometime stop this by offering to contribute to the replacement cost as a friendly gesture and taking the offending article away in "part exchange". if you do that beware that you'll be blamed for anything that goes wrong with the item the PSU feeds for years to come though. Such is life.

      Re: Rein issue

      There's a good chance it was one of the cheapo Apple adapters which have been causing lots of problems. Mobile phone chargers in general are known to cause interference in some conditions.
