TP-Link Gigabit Powerline Starter Kit review

Today I’m reviewing the pair of TP-Link 1000 Mbps Gigabit Powerline Starter Kits that I bought earlier this year to improve our network at home. If you haven’t already, please read yesterday’s post for some context, although I’ll summarise here too.

My aim was to improve the network speeds on some of the devices that I own, thus freeing up Wifi capacity. I went with Powerline (also known as HomePlug) because it would be less disruptive to install than Ethernet cables.

The TP-Link units were well-reviewed on Amazon, averaging 4.5 stars with over 1000 reviews at time of writing. I needed three adaptors; unfortunately I could only find them in packs of two, and so ended up buying four. At the time, this set me back £80, but they’re now down to £36 for a pack (so £72 for two).

Installing the Powerline adaptors

Setup is a doddle. Each starter pack includes two Powerline adaptors, and two standard two metre Ethernet cables. You plug one adaptor into a wall socket near your router and connect it up with an Ethernet cable, and then use the other adaptor and cable to connect to your device in another room. Ensure the adaptors are switched on at the wall, and your device should connect, just like it would if there was a direct Ethernet cable linking it to the router. Repeat this for any additional adaptors – you can use more than two in the same home.

There’s no special software to install, and unlike Wi-Fi routers, there’s no configuration either. It’s literally just ‘plug and play’.

That being said, each adaptor has a ‘Pair’ button, and it’s recommended that you press this on each adaptor in turn. This encrypts the signal between each adaptor, so if there’s any signal leakage with a neighbour, their Powerline adaptors won’t be able to connect to your network and vice versa. It’s a bit like enabling WPA on your Wi-Fi, and it doesn’t seem to have any discernible effect on performance.

Performance

Speaking of performance, the TP-Link adaptors seem to work well. The speeds and latency are certainly better than I was getting over Wifi. Internet-based tests like Ookla’s Speedtest seem to suggest that I’m able to take full advantage of my internet’s connection speed.

As I mentioned yesterday, our household electrical wiring is of variable quality and I was concerned that the older wiring would affect speeds. This doesn’t look to be the case, and the Powerline signal works across our fuse box to serve different electrical rings.

It is worth pointing out that you ‘lose’ an electrical socket when using these adaptors. This isn’t much of a problem for us; when we had the downstairs rewired, we deliberately installed far more sockets than we needed. If you are short of sockets, then you can pay extra for adaptors with a pass-through capability. They work the same but you can still plug another AC device in; however, they cost £50 for a pair, rather than £36.

Compatibility

As I was starting from scratch, I deliberately bought two pairs of adaptors from the same manufacturer. The good news is that HomePlug is an agreed standard (IEEE 1901), and these TP-Link adaptors comply with the HomePlug AV2 specification. This means that if I wanted to expand the network even further, I could theoretically use any HomePlug AV2 compliant hardware to do so – I wouldn’t necessarily need to buy TP-Link equipment again. As it is, I have a spare adaptor since I only needed three.

Conclusion

I’m really impressed with the TP-Link Powerline units. They deliver a good, fast connection, and have worked well in the couple of months that I’ve had them. Whilst it would have been nice to save a bit of money and buy a pack of three adaptors, rather than two pairs, at least I have a spare adaptor for future expansion.

If you have problems with your Wi-Fi speeds or signal strength – especially if your home is around 100 years old and built of stone, like ours – then Powerline adaptors may be a good solution for you.

Update (January 2025): this model is no longer available, but here’s a sponsored link to some newer ones on Amazon.

Adventures in home networking

by
Wires

We’ve been living in our house for approaching two years, and in all of that time we’ve been reliant on Wi-Fi for our home networking. Our phone line enters the house in a spare bedroom so that’s where our ADSL modem is (a BT Home Hub 4, although we’re no longer with BT). This isn’t too bad from a Wi-Fi signal perspective, as it’s located close to the middle of the house, but we still have some signal issues in the kitchen which is the furthest room.

For this reason, we have a Netgear Wi-Fi range extender which ensures an adequate signal in those parts of the house. Combined, the whole of the house is covered.

Limitations of Wi-Fi

The problem is that we have quite a lot of devices all using the Wi-Fi connection. There’s my Mac, Chirstine’s laptop, two smartphones, two tablets, a Roku, a Chromecast, a Blu-Ray player, our Nest thermostat and a Kindle, plus any devices that visitors bring. The Roku and Chromecast in particular are used for streaming video which requires a good connection, and I upload photos from my Mac every now and again.

Most of the equipment we have supports the IEEE 802.11n standard and so it’s reasonably quick, but some devices use the older 802.11g standard and not all are compatible with both 2.4 and 5 GHz wireless bands. Wi-Fi also has higher latency than wired solutions. And I have a Raspberry Pi and a Freesat receiver that do not support Wi-Fi at all. The Raspberry Pi currently gets a connection from an Ethernet cable linked to the Netgear extender, but the Freesat box has been isolated from the internet.

It would be great if everything supported the new 802.11ac standard. But this would require us to replace all of our devices and so isn’t likely to happen soon.

Laying Ethernet cable

The optimum home networking solution would be to lay Ethernet cable across the house, with ports in each room. That would ensure at least Gigabit connection speeds everywhere, with almost no latency.

We had most of the downstairs rewired before we moved in a couple of years ago and, with hindsight, this would have been an ideal time to install network sockets. Sadly, we didn’t, and trying to install sockets now would be very disruptive. I’d rather not have cables trailing around, or even fixed to walls, seeing as our toddler will inevitably want to play with them. Whilst I could probably do this myself, I’d rather not have to cut and crimp network cables.

Power line networking

Which leaves power line networking, also known as Homeplug. This uses your household electric circuits to carry a network connection, with adaptors that plug into your existing electrical sockets.

I was a little hesitant to try this, as our wiring is of variable quality. Obviously the downstairs wiring is good, having only been installed two years ago. But upstairs, some of the wiring is much, much older; in some cases, dating back to the 1950s. I was also worried about whether the signal would pass through our fusebox (which is thankfully quite new), as the upstairs and downstairs are on separate electrical rings.

I decided to take a punt, and ordered some well-reviewed Homeplug networking adaptors from Amazon – I’ll review them later on. At £80 for four, I felt this would be cheaper and less disruptive than installing Ethernet cable. And, so far, so good. I’m using three of the four adaptors; one of them connects in turn to an old Ethernet switch that I had, to provide connection to our Blu-Ray player, Roku and Freesat box.

My worries about the wiring seemed to be unfounded – we’re getting good speeds and much lower latency than on Wi-Fi. In particular, I can upload photos from my Mac much more quickly now than I ever could on just a wireless connection. I’m glad to have a better connection without having to tear the house apart, or replace all of my devices.
