Hi, I have very low 2.4 GHz speed on OpenWrt even when standing next to the router. My phone is definitely connected to the 2.4 GHz SSID because I separated 2.4 and 5 GHz into different names. Current settings are AX mode, channel 11, 20 MHz width, country SK, and legacy 802.11b rates disabled. LuCI shows about -26 dBm signal and 114.7 Mbit/s bitrate near the router, but Speedtest is only around 26 Mbps. 5 GHz works better. What should I check next for low 2.4 GHz throughput with good signal? Thanks
I could be totally wrong, but:
Try moving further away. Phones in particular can be very sensitive and the input stages of the wireless input could be saturating resulting in dropped frames. -26dBm is a very strong signal in wi-fi terms.
Typically, -65dBm is regarded as a good strong signal.
Check my maths on this:
65-26=39 dBm higher.
3dBm is a doubling of power.
So 39/3 = 13 doublings.
ie 2^13=8192 times more power than -65dBm
Some radio receivers are ok with this, but some are not.
Many phones don't know what AX is so on 2.4GHz default to 802.11n, so the absolute max theoretical bitrate will be 150Mb/s, so achieving 114Mb/s bitrate is pretty good.
But with input saturation causing frame drops, 26Mb/s may well be plausible....
Everyone assumes they understand what you mean by that but it would be best if you quantify distane and from what direction.
For sport: how far before you have no issues?
Hi,
I was about 20 cm in front of the router when testing. Signal was around -26 dBm and link rate about 114.7 Mbit/s on 2.4 GHz, but actual throughput was only ~26 Mbps.
Hi ,I also tested from farther away. In another room, roughly 10 meters from the router, 2.4 GHz was still not very good. Outside, about 15 meters away with the signal going through the house, it could barely connect. So it doesn’t seem to be only a ‘too close to the router’ issue.
There is a near field that is a very complicated equation but high school close enough is 1/6-1/2 a wavelength from an antenna has no photons formed.
Not to be confused with a null zone.
Stay over a foot away.
Okay, so the signal won't be any better?
I do not like stepping on another thread.
I just have a habit of not going for the obvious.
He knows the protocols best.
If he gets nowhere, we can troubleshoot physics.*
Now that you know, just apply it and work with @bluewavenet. He knows but sometimes we get get habitual in our trouble shooting.
e.g. if you point the top of an antenna at you, that is the null zone (usually) and is also, practically, useless.
*lol
@bluewavenet can school me in physics and has, so...
@BAMBUSKOOOOO has not mentioned what model the router is but seems to be saying it does not matter how far away he is, performance is still bad.
So the next logical conclusion is that he has faulty hardware....
To be fair:
We don't know they are not trying to move files from a 2005 SD card...
There are a lot of unknowns.
Hi , router IS cudy AX3000
https://www.alza.sk/cudy-ax3000-gigabit-wifi-6-mesh-router-d7973309.htm
So we can see what versions of everything, please share the output of:
ubus call system board
Paste the output between two lines each containing three backtics. The backtic key is usually at the top left of most keyboards.
Three backtics looks like this: ```
root@OpenWrt:~# ubus call system board

Here you are
The current stable release is 25.12.2.
The version you are running (24.10.4) is well past End of Life and is no longer supported.
Maybe there was a bug that caused your problem, I don't recall.
Anyway, before going any further you should reflash with 25.12.2. You can search on this forum to see the numerous methods of doing this.
Do you have the WR3000P or WR3000H?
Hi it is clasic WR3000 with
okay thank you I will try
Hi, that update didn't help at all.
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button (red circle; this works best in the 'Markdown' composer view in the blue oval):
