Right now I don't know if the reason why I'm unable to get the same ideal speed over wifi (as I'm getting on cable now) is related to this FA feature and/or any other settings..


How fast is the WLAN now?

the 850Mbit you measured via cable are not possible via WLAN (at least not with 80Mhz 2x2)

that has a gross data rate of max 866Mbit
under optimal conditions this corresponds to a net data rate of ~550Mbit

as said also show the WLAN status page with a connected 5ghz client

Hello ho1Aetoo!

Indeed! That's what I would get with the native firmware mayybeee a bit more up to 600-620 Mbps but regardless 550 Mbps would be great.

I've attached a screenshot with the speeds.

The first entry is by cable so pretty cool there. The second one is Wifi based.

I'm also attaching a second screenshot as requested with the connected client (my laptop to the 5Ghz).

Thank you again!
Radu

Here's another screenshot with another test on Wifi - slightly faster.

Something I noticed: the rate, at times, jumps from 800+ to 500+ and in between these values.

Cheers!

The WLAN status looks okay for now.
Noise might be a bit too high (but I do not have a direct comparison).

Now you can start with the fine tuning.
The selected WLAN channel can definitely change the throughput.

So start a WLAN search (site survey) and sort the table by clicking on Signal.

see which frequencies are used in the immediate vicinity

there are a total of 6 80Mhz blocks that come into question.

36-48
52-64
100-112
116-128
132-144
149-161

the availability and transmission power limits - depend on the region (regulatory domain)

also you could measure the bandwidth directly between router and client via iperf3 ( instead of WAN > WLAN)

this is the worst speed test site..ever Razz

try this one.. http://www.dslreports.com/speedtest?nav=2 make sure you tick Hi-Res BufferBloat box

as, well make sure you read and understood https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=327595

last, not to mention clients are also playing a big role, in terms of their compatibility and capability too...

Hello ho1Aetoo,

Eh..I admit I've heard/read about site survey but I'm not sure how I can do this nor what iperf3 is.. Apologies.

Could you perhaps tell me how I can do this?

Thank you,

Hello Alozaros,

I didn't know that it was bad, I used it as it was something I saw in the Microsoft store. Nevertheless I've ticket the box you mentioned and I've attached a screenshot of the result.

Regarding the wiki you attached - I'm not yet done with all the reading.. nor do I understand it entirely. I did start reading it a couple of days ago. However, in the meantime, should I use the commands listed there? These commands I mean.

"Upload test: iperf3 -c #.#.#.# -b1000M -w750k -P20 -V
Download test iperf3 -c #.#.#.# -b1000M -w750k -P20 -V -R"

Thanks,
Radu

Hello ho1Aetoo,

Thank you! Here are the results attached.

I'm pretty much the only one I guess..."OtterlandDeco" is also mine, it's a tp-link m5 mesh system I have but it is disconnected and not used now (It only has AC power plugged in).

This falls into the category of advanced users.
Iperf3 is not quite trivial.

first you have to log in via telnet or ssh on the router and start the iperf3 server

Code:
iperf3 -s


then you have to install iperf3 on your client

https://iperf.fr/iperf-download.php

Iperf is a command line program

You start the client like this:

Code:
iperf3 -c 192.168.1.1 -t 60

upload

Code:
iperf3 -c 192.168.1.1 -t 60 -P4

upload 4 streams

Code:
iperf3 -Rc 192.168.1.1 -t 60

download

Code:
iperf3 -Rc 192.168.1.1 -t 60 -P4

download 4 streams

all 60 seconds

then best to search again
otherwise these are ideal conditions, in this case in Europe it is best to use 36 lower lower or 52 lower lower

(so 52 to avoid the mesh)

Hello ho1Aetoo,

Ok - I didn't know that so now I've changed the Regulatory Domain to Europe, channel 52 and extension channel to lower lower.

I've also disconnected the main Deco so now only the other two appear on the survey but they're not doing anything (not that they were before) so here's the new screenshot.

Thanks!
Radu

Hi again everyone,

Just to get something straight please - because I didn't understand completely - is the missing FA and/or the other wlan advanced settings playing a definitive role here any more?

What I mean is - if I get another beta version with FA and/or I change any other advanced wlan settings will these aspects improve the wifi and the overall functionality?

Thanks..again!

You are measuring something strange, is it only the WLAN connection or is the LAN connection still active?
