SSH access
I don't seem to be able to SSH as admin (or root) into the EAP even though SSH is enabled in site settings. Basically it doesn't like the credentials. Is the password for the EAP different from that for the controller?
I'm now running the SDN controller and could have sworn that, before the change, I could do this. I'm trying to debug suddenly slow wireless speeds (20 Mbps to a wired server with wireless link speed of 650Mbps on an idle 5GHz network) which is a whole story into itself.
Somewhat off topic but is 50% AP memory utilization on an idle network too high?
Thanks

Hi unmesh,
yes, the device password is different from the controller password. You need to use the credentials set in the device account settings. You find this in Site settings:
Omada Controller:
SDN Controller:
In previous controller versions the device account was initially set to the controller's login credentials, which was a security flaw when using Operator roles.
Regarding memory usage: 50% memory usage is pretty normal for an idle EAP.

@unmesh, you're welcome anytime.
Addendum: don't expect too much from SSH access. TP-Link did block root access to the EAP long time ago. Unfortunately, this prevents execution of some commands which could be useful for inspection.

I've now discovered for myself that a bunch of commands are gone :-(
[I should probably start another thread for the following]
ifconfig says the uplink is gigabit, the GUI says wireless utilization is low, but iperf through this AP to a wired server is

I then placed another AP (actually a reconfigured 2 stream AC router) a couple of feet away and got this

@unmesh, looks like you did use the 2.4 GHz WLAN with 20 MHz channel width, right? This will give you a maximum WiFi rate of 144 Mbps and the iperf results are not surprising for 802.11b/g/n mixed mode. Could be a little better, but not much.
Try the 5 GHz band with 80 MHz channel width and 802.11ac-only WiFi mode. Under ideal conditions (free line of sight between client and EAP) I reach an average goodput of 645 Mbps for a WiFi rate of 867 Mbps on an EAP225 as following iperf/WiFiPerf results show:

The PC was connected to the 5GHz radio and the EAP reports Rx Rate:866.00Mbps, Tx Rate:468.00Mbps, Mode: 802.11a/n/ac Channel Width:20/40/80MHz
Is there a way to change mode to AC only?

Hi @unmesh, you could set the WiFi rate in 802.11 rate control (under advanced features) to limit the WiFi modes. However, this menu lacks detailed documentation and I'm still waiting for the FAQ which was announced to further explain this function.
