Dell Wireless 1820A & AP230, only connect at 400Mbps

[sebus]

Replaced (same physical place, same wifi in laptop)

Zyxel NWA1123-ACv2 with AP230

On 5Ghz connection speed dropped from 768Mbps to only 400Mbps (that is HALF)

Not something I expected.

Played with all the settings available in Connect, no difference, cannot make it nowhere near the same speed.

Anybody has any ideas?

Thanks

Well, what can I say to convince you?

With no option in driver, withOUT “band-steering mode force-5g” in AP config client will connect only to 2.4Ghz, WITH “band-steering mode force-5g” in AP config, same client will connect to 5Ghz

While I know the commands for A-MPDU & A-MSDU because the lot is available ie here

I have checked my enterprise config & while Enable aggregate... is checked in ac radio profile, it does not reflect in the actual config, it only shows in the ng radio profile (hence the question, because it makes no sense to me)

To enable frame aggregation there are two CLI commands:

radio profile <string> ampdu for A-MPDU

and

radio profile <string> amsdu for A-MSDU

Just because the client does not offer an option to select a frequency does not mean that the client does not make the decision. The AP can offer the client the SSID and connection options, but it cannot decide which of the options the client has to uses, nor which frequency band it uses. 

This also applies when band steering is switched on.

There are two settings regarding frame aggregation:

radio profile <sting> ampd  for a-mpdu

and

radio profile <sting> amsd for a-msdu

Anybody has any idea to what CLI command this translates (on AC radio profile)?

Enable Aggregate MAC Protocol Data Units: Select the check box to enable AMPDU (Aggregate MAC Protocol Data Unit) transmissions to reduce overhead when the transmission channel is busy. When you enable AMPDU, the HiveAP combines data frames into fewer, larger frames before transmitting them and is able to recognize the format of larger frames when it receives them. Generally, enabling AMPDU increases performance. Clear the check box to disable AMPDU. By default, it is enabled.
