Overview

The Linksys A03 V2 is electrically and mechanically identical.


This device was under short-term confidentiality, but that expired 08/26/2018 ⚠.

Limitations

The supported channels of the two 5 GHz radios are severely limited:

 * radio0: supports channels 100 - 144, 149 - 165 (no DFS/TPC needed in the USA). Uses Qualcomm Atheros QCA9886
 * radio1: 2.4 Ghz wireless. supports channels 1-11. Uses Qualcomm Atheros IPQ4019
 * radio2: supports channels 36 - 64 (no DFS/TPC needed in the USA). Uses

Channels 32, 68, 96 and 169 - 177 are unusable on either radios. This means that these devices cannot in general connect as clients to existing 5 GHz networks, and thus cannot repeat them, which severely limits the usefulness of having dual 5 GHz radios.

Also, you cannot tie the WAN and LAN ports together under the same VLAN because they live on different switches.
