BT Broadband Extender Powerline Adapter Flex 600 Kit, wired AV600, pass-through socket

Many people have complained about the unreliability here. I tried out quite a few different powerline adapters, and so far these were the only ones that did not produce a deafening, or at least loud, high pitched sound. Therefore, I was forced to persist with these, and I found out how to get them to work best. Note that I am reviewing the AV2+ standard adapters (the Flex 1000 line). I did try out the AV standard adapters (Flex 600 line) but these always dropped out seconds after being paired. Here are the steps I followed to get the Flex 1000s to work.1. The Extender 1000 (not the flex) should be used as the "distributor". This piece of kit creates a significantly stronger signal than the Extender Flex 1000s.2. The distributor should be plugged into a socket where ideally nothing else, or only very light devices are plugged in (e.g. lamps). Certainly, they must be plugged into a socket where no motor-machines (e.g. desktop computers, fans) are also plugged in. These create magnetic fields which greatly disrupt the distribution of the signal. This is true for all powerline adapters, but especially so for the BT ones.3. This may necessitate taking an ethernet cable a bit of a distance from the router to the distributor powerline adapter. In terms of impact on signal strength, this is absolutely fine.4. Placing the distributor close to the router will lead to a great drop in performance. This is because the powerline system uses radio frequency signals, sent through the cabling of the house - wifi from the router, also being radio-frequency, will disrupt this.5. The receivers should be located far away from motors of any type, and ideally in a socket of their own. However, if the distributor is located in an ideal location, then the receiver will still give very good speeds. I have a receiver right next to a desktop computer that gives a very usable 17 Mbit vs a practical maximum of 36 Mbit. Furthermore, receivers located 1.5m away from desktop computers give 32-34 Mbit.6. If you do have a device close to the receiver, then your receiver should be the Extender Flex 1000, and the device should be plugged into it. There should be no other device plugged into the adjacent socket in a double-socket. More devices plugged into different but nearby plug-socket pattresses are fine. However, any motor device (e.g. desktop computer) must be plugged into the powerline adapter.7. These extenders (like most other extenders) will not function reliably if extenders from other companies are also being used. TP-link adapters, for example, will disrupt the connection, even if they are not paired, simply as a result of being plugged in.8. Once you have physically set up the network, it is recommended that you turn off all the plugs in your house, then turn off all the sockets at the fuse-box for 15 minutes. For some reason, these adapters seem to benefit from this.9. Only after this, must you go around from powerline to powerline, pairing between the distributor Extender 1000 and the receiver Extender 1000s/Extender Flex 1000s. Although I am not sure, I think adapters paired last achieve higher speeds, compared to if they were paired earlier.10. Each adapter you add will reduce your speeds elsewhere by about 500 Mbit/s.Following these steps has given me, so far, a fast and stable connection without the high-pitched whine of other adapters. The connection does drop out occasionally, but the adapters are resilient to this and come back on a few seconds later. In my experience, this is unavoidable with all powerline adapters. Having said all this, I have only recently set these up, so if they do not prove reliable I will update the review.Update: A power-cut will necessitate a repetition of this process.Major Update: Having plug sockets with usb-ports installed elsewhere in the home will strongly harm the speed and reliability of these when motor-machines like desktops are plugged into them (the Flexes). My speed has reached nearly maximum network speed after replacing these plug sockets with standard ones, and furthermore power-cuts no longer have any impact.Major Update#2: Reliability of these will be nearly flawless when connected to the same ring circuit in the house. The connection will persist through power cuts. If they are connected on different ring then the connection will be dropped in the event of a power cut.Major Update#3: I can no longer recommend the standard (non-Flex) version of these. They only have a plastic earth, and it seems therefore that they are not surge protected. This means that in some routers they will cause the internet to drop off when there is a power fluctuation, even when the router is connected to a surge protector. I have replaced the central distributor with a 1000 Flex and my internet has become flawlessly reliable - not a single dropout or event.

Arrived before the delivery date. well packaged and great service from the seller.Love these things, bought two packs now to pipe broadband around my home. We live in poor area for TV reception via signals and I am not paying Sky's silly prices for multiroom for the kids to have TV. I am therefore left with streaming live TV for their bedrooms via android boxes. The wireless option was beginning to show signs of strain even for BT hub 5 on infinity 2 that I have; since about 7 devices including various mobile phones and a PC were demanding the signal. The line speed in my area is very good, far more than the 72 meg BT said I would get. Having clocked it a 96mb on most occasions.Installing these items gives me a constant line speed in every room of the house that i have one installed. (Installed by means of plugging it into the plug socket and turning it on)They plug in and hey presto you can connect two devices via Ethernet cable to each one. No more buffering, or loss of signal that wireless gave me.Currently have four devices connected to four of these. 3 android boxes in separate rooms and PC computer. The android boxes can stream live HD TV and the PC can be used for online gaming keeping the children happy without loss of signal or buffering I have a sky HD box plugged into the main BT HUB 5 and this can be used to watch a HD movie from sky cinema all at the same time without issue.They are very easy to install, just follow the instructions, especially when trying to install more than two of them.They are expensive and might be some others on the market for cheaper. But with having a BT hub, BT broadband and BT phones I just went for a brand that works and these do work.Great product highly recommend if like me you are having issues around your home with wireless signals.
