Usage Guidelines

Usage Scenario

Some non-HT STAs that support 802.11a/b/g cannot receive packets sent by APs using multiple antennas. As a result, network access failures, frequent STA roaming, or network instability is caused. After running the single-txchain enable command to enable the single-antenna transmission mode in an SSID profile, management packets on the corresponding VAP and data packets sent by the AP to non-HT STAs on the VAP will be sent in single-antenna transmission mode. For a radio that is bound to a VAP with the single-antenna transmission mode enabled, control packets of the radio are sent in single-antenna transmission mode as long as non-HT STAs is connected to the VAP. When no non-HT STA is connected to the VAP, the control packets are still sent in multi-antenna transmission mode.


Only 802.11ac Wave 2 APs support the single-antenna transmission mode.

After the single-antenna transmission mode is enabled in an SSID profile, the receive signal strength of STAs may be affected.
