2.4ghz network very slow in EAP245 and EAP225
I am wondering if anyone else has the same 2.4ghz wifi network issue, It's extremely slow. 5ghz works fine
Speedtest 5ghz : 300 Mbps dwonload, 20 mbps upload
Speedtest 2.4ghz: .1 Mbps download, 2 Mbps upload
Latest firmware installed, different channels, I currently have only one 2.4ghz network, no interference with any other wifi network.
The same results with a EAP225.
Tired of trying everything I set up the original wireless router I had before buying this AP and the 2.4ghz network works way better.
Am I missing something ? Anyone can help me before I return this AP
Thanks in advance

@Hac Yes, there's something wrong with 2.4Ghz.. but it seems TP link dont care about it...

I get normal speeds for 2.4GHz using both EAP225 and EAP245. Some interference from others, but not severe.
North American versions, using latest firmware. I'm using 20MHz only and get ~60Mbps.
PHY rate 217Mbps, RSSI -66, noise -92

Okay, i would really like to know how to achieve that. It's probably just a stupid setting somewhere messing it up

@blj-74 Here are my 2.4GHz radio settings. I'm using the Omada Software Controller (on a Raspberry Pi) to control these, but that should not matter.
Status: Enable
Mode: 802..11b/g/n (mixed) <- probably the most important setting
Channel Width: 20 MHz
Channel: 6 / 2437 MHz (i alternate channels 1,6,11 among the APs I have)
Tx Power: Custom
6 (6-24 dBm)
That's an EAP245 I just connected to. The other EAPs (245 and 225) are configured similarly, just different channel and Tx Power.
Just note that 2.4GHz was the original unlicensed spectrum, so everything used it. Cordless home phones, baby monitors, bluetooth, ZigBee, etc. It's a long list.

You can have a lot of interference on 2.4GHz without any other wifi around.
Try different channels to see if one works better than others. Here just some IoT devices use 2.4GHz channels so we don't care about their speed anyway and we moved all our computers, tablets and phones to 5G.

Same issue, 2.4 is very slow. 5ghz works great. I think they need to update firmware. 2.4Ghz should also have a longer range but doesn't. I just bought mine today. I'll call tech support tomorrow to see if they can help.

Same problem, I have 5 EAP245 V3.0 (1 from US and 4 from EU), they all have the same problem!
I suffer from very slow internet speed at 2.4GHz other than 5GHz
Subscription speed 200Mbps
Cable/Wire = ~200Mbps
Wireless 5GHz = ~155Mbps
Wireless 2.4GHz = ~6Mbps !!!
I've tested all channels at 2.4GHz (all 13 channels) and they all give me almost the same result!
I tried another router (Linksys WRT1900ACS), it was giving me ~55Mbps at 2.4GHz and 199Mbps at 5GHz.
I did everything according to my experience, and I got no positive result!
I had never had this problem before until I updated all EAP245. All devices right now have the latest update 5.0.0!
PS: I've 9 wireless surveillance cameras, 24 SONOS One SL wireless speakers, and several wireless and Bluetooth devices inside and around the building. I have a big building, I can't use 5GHz everywhere.
I gave up trying, I want to help please.
Thank you
Edited: I disabled Wi-Fi Multimedia (WMM) and the download speed improved slightly, but the upload speed was reduced.
Method: Go to Devices > choose your EAP device > Config > Advanced > and disable Wi-Fi Multimedia (WMM).
PS: Don't do that on 5GHz, it will affect the download speed.
I know this is not a perfect solution, but nothing we can do while TP-Link's technical support is ignoring our problems!
