Devolo powerline wifi adaptor not working

[#1]

I have an issue with my devolo dLAN AV500 wifi plug. My home network setup also includes two (2) standard AV500 plugs.

I use the devolo Cockpit software and all the devices are displayed correctly and all work satisfactorily over ethernet using a BT Smart Hub 6 broadband router on PlusNet fibre optic broadband.

I have gone through the wifi set-up process many times and had come to the conclusion the plug was faulty. To this end I purchased a new dLAN 500AV wifi starter kit but after fitting them the result is the same.

I have tested the wifi plug in different parts of my house but the effect is the same.

Using wifi analyser software the signal strength is very good but when carrying out an internet speed test the throughput is very low, i.e. at best of the order of a few Mbps maximum download.

i have refitted the PlusNet Hub One router but the result is the same.

Any help would be gratefully accepted.

I should add that the wifi on the BT Smart Hub 6 is excellent.

Sorry if I'm asking the bleedin' obvious but when you move away from your router you are switching and selecting the Devolo SSID on your device?

[#4]

Thanks forthe reply.

Yes I am switching to the devolo wifi on my devices. No success with either phone or tablet.

Have you tried a different channel number ?

[#6]

Yes I've tried various channels based on channels recommended by the WiFi Analyzer app.

Strange isn't it?

[#7]

Ignore the analyzer for now, try channels 1, 6 and 11

[#8]

Results:

Download/Upload Mbps

Channel 1: 1.75 / 8.27

Channel 6: 3.94 / 8.63

Channel 11: 1.83 / 7.92

Upload speeds look good but the download speeds are way out.

what are the speeds like on the router ?

[#10]

The BT Hub 6 router on wifi is Upload 11.0 / Download 9.68 on Channel 6 standing a couple of metres from it.

[#11]

Depending on the package you’ve gone for, I’d expect download speeds to be at least around 4x upload speeds.

Have you a device that can be plugged into the router using an Ethernet cable ?
If not you need Plusnet to test your line....

[#12]

Just speed tested my Windows 10 PC, which is on Ethernet via powerlines, resulting in 30.20 Mbps download and 18.56 Mbps upload.

My son is currently working at home so that will be slowing the speeds.

[#13]

You need to eliminate the powerlines.

Try https://speedtest.btwholesale.com/ on your PC. Not sure how accurate It is over powerlines.

[#14]

I think we can say the speed into the property it not the problem.

Also, the router wifi is appears to be 3 - 4 times faster than the devolo powerline wifi so perhaps that is the issue.

I'm starting to think about a different approach. If I get another PlusNet Hub One I can restall the one I already have and set the new one up as a repeater. Maybe that will be more robust.

[#15]

Your choice but I’d wait to see if a more knowledgeable member of the forum can help.

Even with limited info a Plusnet line test would be helpful if only to eliminate external issues.
