Puzzling Wi-Fi Powerline behaviour - help

tgg

I can see what channel my phone and tablet are receiving but I don't know to see that on, say, a smart tv.

Can you try killing the wifi on all the Devolos apart from the one near your kit? That will force it to use the near one.

You can turn the wifi off by using that wifi button.

That's what I did. See my reply to you :-) . I only have two Powerline Wifi thingies.

Hi,

The pair of Tp-Link Deco P9 arrived yesderday. I removed the Devolo units and place the two Deco units in exactly the same location yesterday afternoon. It's been just over a day and the reliability has been absolutely fine, but time will tell.

The speed is MUUUCH better on the first floor. The WiFi speed matches the wired speed; Wired (PC) = 250-300Mbps, Wifi (phone) = 250-300Mbps

The wired and WiFi speeds on the ground floor are also the same as each other, but much slower. The TV is connect to the P9 by ethernet cable. Here
Wired (TV) = 50-80Mbps, Wifi (phone) = 50-80Mbps. I think this is understandable because the distance and structures (old house with solid walls) between the 1st floor unit and the ground floor unit prevent the best WiFi (even with meshing magic), and powerline, as has been mentioned, has it's limits. Perhaps with one more Wi-Fi-meshing P9 unit, placed strategically on the landing or hallway, the WiFi may be improved, but TBH, I'm happy if things remain as they are.

I've installed a nice, useful app (Analiti) on my Android TV that I've set to perform a speed check every hour. You can call up historic data so it's an easy way to log the speed and reliability on the ground floor.

I'll post again in a few weeks to update on the speeds and stability.

Many thanks again for all the input from everyone, and have a very Merry Christmas 🙏
 
Good luck tgg

We are off for two weeks holiday tomorrow.

Hope you are still in contact with the magical world of broadband when we get back
 
Hi All,

I just thought I'd give you a quick update.

The Deco P9 units are working VERY well and have been unfailingly reliable (tempting fate?). The Deco Wi-Fi speeds on the 1st floor continue to be the same as the wired-to-the-router speeds . The ground floor, powerline+mesh speed are also steady and solid at 60-80 Mbps.

A small issue I had was that I effectively had two home networks; the Deco network (all devices on wi-fi and powerline) and my PC which was wired directly to the router, not the Deco. I realised that I did not have access to the shared folders on my PC (music etc.). I plugged the PC into the 1st floor Deco P9 to solve this.

So if anyone out there has the same "problem" is I did, TP-Link Deco P9 will fix it reliably. Pre-loved ones tend to go for around £45 per unit on ebay.

I hope you all have swell 2024.
 
Good news then gg.

I have stayed with Devolo since I started my broadband network - and upgraded to, finally, the Magic 6.

I have never really studied the TP system but got an impression it was harder to configure. Having read about the Deco P9 it seems to be a similar mix of powerline and wifi to the Devolo Magic 6. And if there are £45 units around it is a much cheaper option.

Any comments gg ?

Hi,

Just a final update to say that the Deco units are still working pretty well. There was a little moment a couple of days ago when the ground floor unit had a strop and decided it no longer wanted to be part of the network. Power cycling didn't help. It needed a reset and adding to the Deco network again, but it's been ok since then.
 
One area overlooked is the ethernet ports are 10/100 (100Mbps) on the powerline adapters, so you aren't going to see more than 90Mbps (Ish) regardless.

EDIT: A bit 'late to the party', however explains the slower than expected speeds.

That's pretty interesting and confirmed below for a model around that time.

Wasn't aware that restriction/bottleneck wasn't lifted until a later model and it's a little silly to imply 200 Mbps and 500 Mbps bidirectional throughput with such a bottleneck in place.

It's the usual rubbish marketing for these kid of products.

The reason they get away with it is usually due to the throughput available across multiple devices.

This is what mine are showing now.

Theoretically, 100 Mbps ports would have been a bottleneck for the 200 Mbps and 500 Mbps (bidrectional) dLAN links so I'm glad they decided to fix this on later models. Quite a cheap thing to do even on earlier models.

I guess the thinking is that TVs frequently have a 100 Mbps NIC even in recent years.
