Mesh network speed loss help! (sorry)

wifi chip in laptop sounds like its the common limiting factor.

what do other devices do?

what do other devices do?

All very similar.

Weirdly if I try and use Ookla speed test it will not find 'optimal server' sometimes so will not even perform the test.

I believe they have an app that will help set up the network, might need to move to a different channel or something. Have you done that?

Is it putting out a dual band signal with the same SSID, and your device(s) is picking up the 2.4ghz one, which is slower?

Yeah, there's a Network Optimization thing in the Deco app.

Tried that - not made any difference unfortunately. It appears on the M5 there is no way to manually swap channels, just use optimisation and it does it automatically.

What's the backhaul?

It sounds like you were using this prior to the fibre. What were you seeing then?

It was Sky copper connection through their router and ethernet to the Deco network with everything connecting to the Deco , not Sky. That was at best 16mpbs at source and roughly 10-12 on wifi. So I guess that is similar ish loss ...

I rebooted the Deco's before creating the new network on fibre.

What else is connected to the wi-fi? Anything with an old networking protocol or similar?

what does your phone get on speed test?

I'd agree this sounds like your laptop's issue. Even if it was using the same channel you're on to do the backhaul, I'd expect at most a ~50% drop in performance, not 90%

Lots of stuff !

PS4

LG TV - Prob bought 2017/18

2 x work laptops

2 x home laptops

1x Desktop

1 x Naim Muso HiFi Gen 1

4 x Iphones

1 x iPad

1 x wifi hob

1 x EvoHome control unit

... I think thats it! ?!  Obviously all these are not using data all the time. What is an 'old network protocol' ?

what does your phone get on speed test?

Sat at my desk here now and just got 37.4mbps on Ookla iphone 11 pro. The Deco M5 2 metres away on the landing got 285mbps using Deco/Ethernet/Laptop.  Which is weird seeing as though that Deco gets its signal from the main hub downstairs over wifi !

What’s the backhaul?

Ie, how is the mesh interconnected?

Successive Wi-Fi hops will kill performance, your 120Mbps is about what I'd expect. Your lower figures are probably down to signal strength from the client.

Ooh Ooh me me! i think i can help, possibly!

I had this problem, check HERE  on the TP Link website. At the bottom of the page it suggested removing the QoS settings (or increasing to 1000mbps or above). Then turn off UPNP. All done in the Deco app.

I changed providers at the beginning of the month and had an increase in speed as well, it exceeded the QoS max setting so the Deco throttled the WiFi depending on what other devices were connected (hence the varied results) but left the wired connection alone.

Why would UPNP affect connection speed? It is basically automatic port forwarding.

My suggestion would be to make the system as simple as possible then see if you can still reproduce the fault.

For example, if you can still reproduce the fault with a single mesh node connected by ethernet backhaul, you know the fault is not caused by slow wifi backhaul.

QoS is worthless imo. Especially if you have a 100Mbps or fatter connection.

I found it only messed things up with my ASUS setup.

Dongknowstech I have found helpful on various setup matters.

Plus, what @cougar said.

Well the idea of QOS if properly implemented isn't worthless because no matter how fast your connection is, somebody can still max it out with a big download, torrent or whatever and kill your ability to make VOIP calls. Problem is some implementations are a bit ropey.

Can't edit my post now but just to be clear, what I posted above wasn't a criticism of @fettlin but of TP Link's 'help' document which smacks of turning on and off random things

@fettlin I’ve tried all, I found the same article earlier , made no difference unfortunately

weirdly I did the bit where it says disconnect your connection after every speed test.

so normal speedtest on iPhone 35mbps. Disconnected and ‘forgot’ the network, reconnected, re did the line test and got 150Mbps less than a minute later without moving 🤷‍♂️

I have ditched their supplied router

Presumably you are still using their supplied router to connect to the fibre wall box and then your base M5 is plugged into the router (that's how mine is set up)? If so, have you remembered to turn off the wifi on the router?

I also had the QOS issue when I upgraded my line speed, and that has actually reminded me to tweak it again following another increase - ta!

Presumably you are still using their supplied router to connect to the fibre wall box

nope wall box straight to deco. Using their router made it even slower

PC can hold on to the wrong channel, etc. So make sure it matches what you expect (so on 5G not 2.4G).
Something like wifi analyzer (on android) might hightlight issues like channel overlap etc?

No idea about Deco I’m afraid but make sure you haven’t inadvertently bypassed the firewall which is likely built into the router… plugging straight into the fibre connection will undoubtedly work but there will not be any firewall on the fibre modem

As mentioned by cougar, I think this is due to the deco using the wifi for its backhaul. If you get rid of the additional nodes temporary and just use the single one at the modem as a router (ie temporarily get rid of the mesh part) does it improve speed?

Did you try what I suggested yet?

Connect one of the mesh nodes to the modem using ethernet. Turn the others off. Connect you phone or laptop to the single remaining mesh node. Test the speed.

Todays update - Yes I had, and on that node I was getting just under the full 300mpbs.

This morning I moved the locations of the 2 & 3rd nodes. They are now both producing around 100mbps which I am happy with. Unfortunately, it means that the garage is now not covered by wifi, which is a problem for using the Turbo trainer, so I have ordered I refurbed Deco M5 off the web for £45

If so, have you remembered to turn off the wifi on the router?

I have put the supplied Linksys Velop AX4200 back in the network as a router. However, for the life of me I cannot see how to turn off the wifi !

can you disable routing on the Deco? you don't really want more than 1 router on your network!

The deco m5 is a dual channel mesh, meaning it has only a 2.4 & 5 GHz radio, the 5GHz is shared between client use & backhaul use meaning you are performance limited on that frq.

Tri band mesh use 2 5GHz radio one for client the other for backhaul meaning you have dedicated bandwidth for each traffic type.
