Model: TL-WPA4220 KIT  
Hardware Version: V3
Firmware Version: 3.0.3

I've installed the AV600 kit with TL-WPA4220 (V3 fw 3.0.3) as wifi extender and TL-PA4010 (it say V2 on the back) as router connecter.

 

The connection works but I'm not getting speeds higher than 60 Mbps. In my router webpage I can see that it the TL-PA4010 device is in the 100 Mpbs mode. In order to reach the advertised 300 Mbps wifi speed I guess the mode should be 1000 Mbps.

 

It's not the router, nor the cable, because when I connect the same cable directly to my laptop with gigabit ethernet I can see in the routers webpage that it's on 1000 Mbps mode and a speedtest results in 300 Mbps speed. My contract with my ISP is 500 Mbps max.

 

How can I get the powerline to function in gigabit mode?

 

I'm not a network specialist, so if i'm wrong about some of the points above, please let me know.

@abos4 The TL-WPA4220 devices  cannot transmit 1000mbps, because their network interface is 2 x 100mps.

 

The AV600 speed is the theoretical maxium transmit speed that you can get under best conditions when connecting two AV600 devices (paired) over the Powerline connection. Your PC will never get more than 100mbps. But the powerline signal will travel longer distance until it drops below 100mbps. 

 

So there is nothing wrong with your notebook that supports gbit speed if you own the TL-WPA4220 devices. It is a technical limitation of these AV600 devices.

 

TP-Link also sells AV600 kits that have 1000mbps network connection but then again, you will never reach 1000mbps with these since the powerline signal starts at 600mbps speed but depending how far the signal has to travel, on the other powerline end your results may wary, in my case, I own the TL-PA6030 AV 600 with 3 x Gbit but the speed I get from the AV600 is about 440 mbps.

 

So whatever AV number you see printed on these powerline devices, it is only the maximum powerline speed (theoretical), e.g. if you buy something with AV2400, in theory you could reach 1000mbps between two powerline devices under best condition even more.

Thanks for the reply. I know that the output ethernet ports of the extender are 100 Mbps max. But the output wifi should be 300 Mbps max right? I don't use a cable for my laptop. There is no ethernet port.

 

Currently the extended wifi speed is below 60 Mbps and I suspect that the router doesn't supply enough speed to the "router connection box" (I mean the device near the router which sends internet over the house electrical circuit to the extender in the other room). Since I see on the routers webpage that it operates in 100 Mbps mode. Is that possible?

@abos4 WiFi speed 300mbps this is also a theoretical maximum, so your mileage may vary. E.g. if neighbors in your area also have WiFi routers, signals interfere and your speed drops.

 

It may help to change the channel in your WPA4220 webpage wireless settings, by default it is set to Auto meaning that it picks something that may be not optimal in your situation.

@StardustOne Thanks for the reply. I'm aware about wifi channels and interference and that might well be the cause. But can you confirm that this given 100 Mbps mode is not the cause?

 

This is a screenshot of the routers webpage. At the bottom it lists the extender (now in the same room as the router and "sender device"). Sorry about that Dutch (Speed is here Snelheid Mb/s) I'm not a specialist but to me, it seems that because it is in 100 Mbps mode, it will never be possible to reach 300 Mbps wifi. Without even considering speed loss due to distance, circuit, interference, etc.

 

I wonder if the "sender box", which has 1 ethernet port, is a Gigabit port and not a Fast Ethernet port. Do you know this?

@abos4 From your screenshot the TL-WPA4220 uses an Ethernet connection? If yes, this would be your maximum speed you get from this device and when you now use it as a WiFi repeater, it would not do more than 100mbps. Even if the TL-WPA4220 can do theoretically 300mbps, when connected with an Ethernet cable 100mbps would be the maximum it could do over WiFi.

@StardustOne The connection is as follows:

 

Router -> Ethernet cable -> TL PA4010 in socket -> Electrical circuit of house -> TL WPA4220 in socket

 

I believe this is the regular setup as described in the instructions. Is there any other option to connect it not through ethernet cable?

 

I'm still mainly concerned about that 1 ethernet port in TL PA4010. Because if that is a Fast Ethernet port of 100 Mbps, how could this kit possibly send max 600 Mbps over the electrical circuit and later max 300 Mbps over wifi from the extender?

@abos4 This combination will never send more than 100Mbit through the electric wire. But the AV600 will help the 100Mbit signal to travel longer distance and is still usable at the other end. The issue with powerline is, that it can theoretically reach another powerline device over a distance of 300 m. So AV600 takes your 100Mbit at the beginning and the technology ensures that you will at least get 100Mbit on the other end. AV600 allows to compensate for bad wiring. When you check the connection speed using tpPCL, you can see how the two devices are linked up. As you can see from my setup, I get some AV600 that have great speed between them but others are really not very useful (below 50Mbps) and the appartment I live in only has 65 square meters in size.

 

 

If I would have bought AV1200, I am pretty sure that my bad connection AV600 would have had a better connection speed. AV600 is your starting point and how much you get on the other end, this depends on many things.

@StardustOne Thanks for your reply and elaborate informatie. It really helps me understand the bigger picture.

 

So this combination/kit does not send more than 100 Mbps over the electric wire... How can this kit than deliver 300 Mbps wifi?

 

And if 100 Mbps is the actual max speed. Why does the app indicate speed ~ 300 Mbps:

 

Btw, the actually measured speed is more than 10 x slower:

Looks like you are using a smartphone to measure the speed?

 

Most phones and laptops only have 1 aerial so on best of days, you might see 50 mbps on 2.4 ghz band using TL-WPA4220. Otherwise, 36-40 mbps is typical best speeds in the real world.

 

If using wired ethernet devices, 60 mbps is actually quite good over powerline adapters in different rooms in the real world. If you plug pair of adapters into same wall socket, you might see 100 mbps through them !

 

The PA4010 and TL-WPA4220 100mb ethernet ports. Your router is wired into one of them. So you will NEVER see more than 100mbps via ethernet or wifi over the powerline network.

@StardustOne 

Hello StardustOne,

 

Similar question about this, if I replace the powerline adapter(PA4022) connected to the gigabit router with a PA7017, can the WIFI speed of the WPA4220 approach 300 Mbs? Will the PA4022P adapters left in the network still work?
