If you have problems with a HomePlug connection, try turning off other devices and see if you can find the culprit. Noise can be created by other electrical products from fridges to smartphone chargers. In this case, it depends on the distance from the router, wiring quality, and the amount of noise present.
Similarly, a HomePlug AV system has a theoretical speed of 200Mbps, but you’re more likely to get 30-60Mbps, sometimes less. It depends partly on the distance from the router, your walls and floors, interference from other networks, and the number of devices sharing your bandwidth. For example, an 802.11n Wi-Fi router may have a theoretical maximum speed of 600Mbps, but you may well get only 40-50Mbps. HomePlug speedsĪs with Wi-Fi, the specified speeds of HomePlug devices are nothing like the actual speeds. Some systems have a “Wi-Fi Extender” mode instead. The Devolo dLan 1200+ gets round this by including “Wi-Fi Move Technology” that lets you use your existing router’s SSID and password to create a single network.
The disadvantage is that a HomePlug usually creates its own separate Wi-Fi network. In my experience with a Devolo dLan 1200+ Wi-Fi ac Starter Kit, this works well. That is to say, the receiver has a small Wi-Fi transmitter as well as one or more RJ-45 ports for wired connections. Some HomePlug devices offer Wi-Fi as well. This may be as simple as holding down the reset button for a couple of seconds on each device. If the devices ship with common default passwords, you should change them, following the instructions in the manual. The pair may be hard-wired with a unique password to talk to one another. There’s a receiver plug that connects to your local device. There’s a sender, which you connect to your router via an Ethernet cable and RJ-45 socket. HomePlug networks are usually sold with two paired devices. HomePlug AV includes 128-bit encryption, in case your mains signals stray onto next door’s wiring.
This should provide much better throughput. The latest AV2 HomePlugs offer MIMO (multiple input multiple output) operation instead of SISO (single input single output). The first HomePlugs were shipped in 2001, and the latest versions are HomePlug AV (2005) and AV2 (2012). The system is overseen by the HomePlug Alliance, which is much like the Wi-Fi Alliance that looks after Wi-Fi. HomePlug was developed to send broadband internet traffic across a home’s – or an office’s – mains electricity cables. Failing that, the best answer is HomePlug, which is what I use.
