Hello,

The other day updated the device too the latest firmware. Since then I am getting normal speed on 5GHz but I am only getting between 0.10mb / 2mb download on 2.4GHz.

The settings are all still the same, so I don't understand what has happened.

Device Name: EAP225-D8-07-B6-2A-71-E6
Model Name: EAP225
Firmware EAP225(EU)_V3_5.0.3 Build 20210316

Any advice please.

Thank you.
 
So today I have tested it again and 2.4ghz is still not fast has it was. I have also noticed that the 5ghz has also dropped speed.
I have 500mb with Virgin hub 3 that is connected too the TP-link via Ethernet cable running from side of the house.

Can you do a speedtest whislt connected by ethernet? Just to rule out any problems with your internet connection.

What are the options for wireless mode on both frequencies? I'd be looking to switch off 802.11b on 2.4GHz and leave 5GHz as 802.11ac only. Change the 2.4GHz channel to 1 then test again. If no better than set it to 6. There's only 3 channels in 2.4GHz that don't overlap - 1, 6 & 11.
 
Well my laptop only supports up to 100mb. When I test speed on my mobile when connected too the hub 3.0 itself, I get around 300mb. However people with iphone etc get 400mb+

I have just done a speed test connected too the TP-Link again and it started of at around 40mb and then it just drops.


The settings available are

2.4GHz
Wireless Mode: 802.11n only, 802.11b/g mixed. 802.11b/g/n mixed.
Channel Width: 20/40MHz, 20MHz, 40MHz

5GHz
Wireless Mode: 802.11ac only. 802.11n.ac mixed. 802.11a/n/ac Mixed.
Channel Width: 20/40/80MHz. 20MHz. 40MHz. 80MHz.
 
I have the same AP's and using the same 5.0.3 firmware, i notice you have your 2GHz set to 20MHz only, have you tried setting this so that its 20MHz/40MHz, i have mine set this way and have no issues.

Your TX Power settings look different to mine (im using the omada controller), i have mine set to High, are you able to set these to the highest possible or is 15 and 20 the max each will go ?
 
2.4GHz is definitely best set to 20MHz. When it's set to 40MHz you're all but guaranteed to be using an overlapping frequency. With 5GHz there's some experimentation required. In my setup 80MHz works well as there is little in the wy of 5GHz interference at my house.

OP - Did you change the 2.4GHz channels as I suggested and then try again?
 
@Bobcat, I have set them back too max.

@the-evaluator, Yes. 802.11n Only. 20MHz.

Chanel 1: 17ms 24.16mb / 41.12mb
Chanel 6: 18ms 32.08mb / 41.93mb
Chanel 11: 17ms 26.36mb / 42.01mb

5GHz set too AC only - 19ms 41.7mb / 41.0mb

I still don't understand why 5GHz is so low, when I get a decent speed when connected too the router.

Should I also change settings on the hub 3.0?

Not sure if this will help, here is the channels of the WIFI around me.

How is the TP-Link connected back to the SH3? Can you do a quick diagram? Is the wifi on the SH3 still on?

There's a fair few other networks using 2.4GHz (nothing surprising there). Can you get similar data for 5GHz?
 
I have an Ethernet cable running from the hub 3.0, up the side of the house into the loft and then into the TP-link that is attached too the celling. The Wifi on the Hub 3.0 is still on has the covers the the ground floor.

My laptop don't support 5GHz, so I will upload image later using app on the phone. They is not many wifi networks showing at the moment.
 
Check the link speed the wifi clients are connected to the access point. Log into the TP-Link web interface -> Status -> Client (look at the second column from the right - Rate Mbps). This tells you the speed the wireless client is connected, the speed drops as the signal gets weaker (move further away, walls in the way etc), this is the theoretical speed, I believe actual speed would be around 80% or lower due to wireless overheads etc.

Check there is no Rate limit set up for each client ("Action" column has a Rate Limit button). There is also Rate Limit options for each wifi radio: Wireless -> Wireless Settings -> 2.4 Ghz -> edit button -> Rate Limit. Make sure its not enabled, also same for the 5Ghz radio settings.

Next I would check the cabling have no errors. In the web interface look at Status -> Device -> Lan Port. It should say 1000Mbps FD. Then Status -> Wireless -> Lan Traffic, make sure there are no dropped packets or Rx/Tx errors under the LAN Traffic section. If you can, use a PC connected with a cable on the LAN and continously ping the TP-Link access point IP address (e.g. ping -t 192.168.0.2) make sure IP address is the correct for your access point. You should see no packet loss and response times 1ms.

You should also check the device uptime to make sure it looks as expected and not doing anything strange like constantly rebooting. Status -> Device -> Uptime

You could try using a different SSID in case someone else is using the same SSID in the area. Optionally you could use same SSID/wifi settings as the VM hub 3.0 but manually set wifi channels on the VM hub 3.0 and TP-Link access point so they use different channels (2.4Ghz choose 1, 6, or 11; for 5Ghz i would pick 36, 40, 44, or 48 and see how you get on, there are other 5Ghz channels but i think these are most compatible for clients but also most likely to be used by other access points). This gives option for clients to roam between access points, the client would usually pick which one has the stronger signal. If you have an android phone there is an app called "WiFi Analyzer (open-source)" by VREM Software Development. This is a useful tool to see which channels are in use in the area.

At this point I would probably factory reset the TP-Link access point and set it up from scratch again. Screenshot or write down your settings before you factory reset it.

(2)
Rate Limit is not enabled.

(3)
It says '100Mbps - FD'.



(4)
Uptime is how it should be.

(6)
I will give that a go.


I just find it strange that the speed is so poor. The speed from the hub 3.0 is normal. It's connected through Ethernet and I thought that means no speed would be lost. I have already done a full reset the other day and it didn't change anything.

5GHz is 36.
2.4GHz is 18.66

EDIT: I've just done a speedtest while connected too the hub 3.0 and it starts of about about 250mb and then drops too 57.90 / 38.40. It was showing normal speed yesterday. :confused:






EDIT:
I did a full reset on the hub 3.0 after posing this. I then left it for a few hours and I've just done a few speedtest on the TP-link on 5GHz.

191mb / 35.9mb ping 18ms Jitter 22ms
56.2mb / 35.0mb ping 18ms Jitter 204ms
53.3mb / 39.1mb ping 18ms Jitter 20ms

(The last two started at about 200mb and the rapidly dropped too about 50mb download)

Update:

So the last couple of days the speed on the TP-Link has massive improved, however the speed from the hub 3.0 on Wi-Fi is still slow :/

I have just done a speed test on 5GHz on Tp-link (289mb / 42.2)
I have just done a speed test on 5GHz on hub 3.0 (126mb / 42.2)

I don't understand how the TP-Link is now fast and the hub 3.0 is still slow.
 
auto channels is your problem. use phone app like wifi analyzer and do proper channel setup. looks to be more user error than hardware issue.
