    Thumbs up Tl pa8030p - interference - going back

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    I thought I would post on here my about my disappointment about this product, ive had loads of 200 and 400 tp link power adapters and never had an issue so I got these about 4 months ago and fitted them into my setup to replace some devolo 650 items. everything seemed fine until my broadband started to slow and I had some drop outs of my router connection to the exchange but not my actual router.

    ive spent hours going round in circles with my broadband supplier and eventually got openreach to attend today. they did line tests and it all seemed fine then he did an error test and found loads then he did an interference test and found a lot of his and lots of clicking. we went round turning off ring mains and all the sockets in the house after about half an hour I traced the interference down to one plug socket that the tp link was plugged into I unplugged and and the errors stopped and the interference stopped. I took the adapter into the engineer and he reset everything and had not interference or clicks then plugged the adapter in and was getting thousands of errors every second and loud clicking through the tester. I unplugged and it stopped we tried the 2nd adapter which we had unplugged because the router was plugged into it for the feed and the same thing happened, I tired the devolo 650+ and got no errors or noise we also tried the 200 and 400 tplink adapters and again no interference or noise detected.

    to say I'm disappointed is an understatement. if the bt engineer hadn't done this I would never of known and I may still get charged by them because it was my equipment at fault. I don't expect this from a 4 month item so anyone getting reduced broadband speed I would try taking these out of your system and reset your router to see if your speed comes back.

    oh btw after resetting my broadband for a 2nd time after no errors was shown my router synced nearly 10meg higher than it had been and hasn't dropped down since.

    poor showing glad I got these through amazon who will be refunding me on these faulty goods

    Well ... the thing is, pretty obviously, that Powerline communications use radio frequency signaling. Domestic power wiring never is shielded, so yes of course, there will be emissions.

    Now powerline has careful regulatory rules so it doesn't disturb any essential radio communications ... but in your own house, wire-to-wire, there will always be interference.

    Since you'll never get your domestic powerline web to not emit anything, the key to happiness is to make sure everything else is done well. One very common mistake is to run phone/DSL cabling in the same tubes as power wiring. One simply does not do that. Follow that rule, and your DSL will be stable again.

    Same goes for disturbance into analog audio equipment. Powerline "noise" may be what exposes it, but the real problem is poor or absent filtering on the power input circuit on your audio equipment.

    [What's the difference between the AV1200 and the lesser standards then? Simple: The AV1200 uses two channels on all three wires, introducing emissions on a pair that is unaffected by the older standards.

    Thanks for your input Peter your points may be valid however the phone line is about 3 feet away from the nearest socket and goes straight out through the wall then directly to the post outside it does not run close to any power lines. The interference we found first was from one adapter in the next room some 16 feet away then tested close by to check it was definitely the adapter.The devolo I am using does the same thing as the tp link adapter using all wiring including the earth to provide the high speeds and causing no interference at all. This has been plugged in since Thursday and my broadband is still syncing and working like it used to.So I'm afraid there is no excuse for these adapters new technology or not they were the cause of my problems which has now been confirmed by the continued stability now they have been removed from my network.
