Model: Archer C2300  
Hardware Version: V2
Firmware Version: 1.1.1 Build 20200918 rel.67850(4555)

Hello, I have purchased Tp-Link Archer C2300 v2.0, I currently have few issues with the router. When I have around 15-20 devices connected to the tplink router.. it slows down to 26-30mbps.. My ISP provides 380mbps download 36mbps upload speed. I have done Speedtest on iPhone 12, I get 26-30mbps, I tried disconnect couple devices from the tplink router.. The speeds goes back up to 370mbps download  and 36mbps upload.. 

I tried to reboot the tplink router, nothing seems not working.. tried everything.

 

Any suggestions why this is happening?

I know you wrote the you've tried everything. But still, can you check that you have disabled (switched off) QoS, Traffic Monitor, Parental Controls?

Traffic monitor, Parental controls are already disabled.

Qos is set on standard, I'm not sure if that is disabled. I don't see any disable QoS option on advanced setup.

Only TP-Link themselves will know whether QoS set to "Standard" means QoS is disabled or if it means QoS is enabled with some "standard" settings. 

 

Personally I am not a fan of the QoS ("Quality of Service") features that come with home grade routers, because to me it seams they rarely live up to their name.

 

Anyway, would it be possible for you to connect your devices one by one and check the speed in between to see if it's maybe one particular device that, if connected, causes the download speed to go down for everyone?

I have disconnect all my devices from the internet.. speed goes back up to 380mbps, I have connect devices back up and run a speed test. 9 devices connected to 5Ghz 2 devices connected to 2.4Ghz. I have disconnect my HomePod mini from the tplink router. Speeds goes back up to 380mbps. So I have connect HomePod back on the internet. Speeds drop down to 30mbps. I have tried different device, I have disconnect my computer from internet, speeds goes back up to 380mbps. Then I connected my computer to the internet, speeds drop back down to 30mbps. Speeds seems drop down when there is around 10 devices to the 5Ghz. Router never has problems when there is only 3-5 devices connected to 5Ghz. 

this is likely do something with router firmware.. 

its getting annoying.
