Speed low with OpenWrt and TP-Link EAP615-Wall v1

Hi! I've installed OpenWrt on my TP-Link EAP615-Wall v1 Access Point. I've connected the LAN POE port to my LAN network. All good so far. I've set up a Wi-Fi connection as an Access Point, but when I try to connect from any client and run a speed test, both download and upload speeds don't exceed 10Mbps. Does anyone have any advice?

Check the port speed using ethtool.

Thanks for the reply.
What do you suggest me?

Output:

oot@OpenWrt:~# ethtool br-lan
Settings for br-lan:

Supported link modes: Not reported
Supported pause frame use: No
Supports auto-negotiation: No
Supported FEC modes: Not reported

try a different ethernet cable 1st.

if no go - https://linuxiac.com/how-to-manipulate-ethernet-card-on-linux-with-ethtool-command/, you don't need to sudo the commands, you're already root.

I tried running this command:

# ethtool -s br-lan speed 1000

but I get: "Cannot set new settings: Not supported not setting speed"

Any suggestions?

I can't use my new access point :frowning:

Can you collect output of ethtool lan0 ?
fyi: this is how it look on my EAP615

Sorry for my ignorance, what is the lan0 interface?
I use the br-lan interface which is the PoE IN one.

I don't own the device, but try the ethtool setting on lan0 instead of br-lan, or eth0 or eth1.

lan0 should be the incoming (PoE) port

Looking at the output, the issue is not within EAP615 but in the device (switch?) with which it has been connected.

For comparison this is the link speed from my switch

Link partner advertised link modes:  10baseT/Half 10baseT/Full 
	                                                  100baseT/Half 100baseT/Full 
	                                                  1000baseT/Full

While this is the link speed from your switch/router
Link partner advertised link modes: 10baseT/Half 10baseT/Full

Thanks a lot!
Now it works!

Ok great - what did you change to get this solved?

The issue was the switch it was connected to.
