Can the IR302 operate as a Transparent Bridge to an existing Access Point (AP)? I am able to configure the IR302 as a WSTA Client, but it operates as a router with an network address on the LAN interface and a different network address on the WLAN interface. I would like it to operate as a Layer 2 wireless device. Is this possible? If so, how is it done?
To answer your question directly: Yes, it is possible, but not in the standard "WSTA Client" mode.
The standard WSTA (Station/Client) mode on the IR302 (and most cellular routers) operates at Layer 3 (Routed). This is due to the 802.11 standard's 3-address frame limitation, which prevents the wireless client from transparently bridging MAC addresses of wired devices behind it without specific "4-address" or "WDS" extensions.
To achieve a Layer 2 Transparent Bridge (where devices on the IR302 LAN get IP addresses directly from your main AP's DHCP server), you must use WDS (Wireless Distribution System) mode.
Configuration Steps for Layer 2 Bridging (WDS)
Change WLAN Mode to AP:
Navigate to Network > WLAN.
By default, the radio might be in AP mode, or you may have switched it to Client (STA) mode. You need to ensure the device is in a mode that supports WDS (often handled within the AP configuration on InHand devices, or a specific Bridge/WDS toggle).
Note: Using WDS implies the IR302 will also rebroadcast a Wi-Fi signal (acting as a repeater).
Enable WDS:
In the WLAN settings (typically under the General or Advanced tab of the AP settings), look for the WDS option.
Check Enable WDS.
Scan and Connect:
Click the Scan button to find your existing Root Access Point (AP).
Select the SSID of your main AP.
Important: You must manually set the IR302 to use the same Wireless Channel and Encryption type/password as the main AP.
Verify Network Bridging:
Once connected, the IR302 creates a Layer 2 bridge.
Go to Network > LAN and ensure the LAN ports and the WLAN interface (often
wlan0or similar) are assigned to the same logical bridge (e.g.,br0).Downstream devices connected to the IR302's Ethernet ports should now receive DHCP leases directly from your main network, not the IR302.
Crucial Limitations & Prerequisites
Upstream Compatibility: WDS is not a strictly standardized protocol across all vendors. For this to work, your Main Access Point (AP) must also support WDS (sometimes called "Bridge Mode" or "Repeater Mode") and may require you to enter the IR302's MAC address into the Main AP's WDS settings. If your main AP is a different brand (e.g., Cisco, Ubiquiti) and does not support universal WDS, this method may fail.
Performance: WDS cuts wireless bandwidth roughly in half because the radio must receive and re-transmit packets on the same channel.
Layer 3 Alternative: If WDS is not possible with your infrastructure, there is no "Magic" Layer 2 transparency in standard Client Mode. You would have to rely on Layer 3 Routing and use features like Port Forwarding or DMZ to reach devices behind the IR302, or use a VPN (like VXLAN or EoIP) if you have a termination point for it.
Summary of Differences
| Feature | WSTA (Client) Mode | WDS (Bridge) Mode |
| OSI Layer | Layer 3 (IP Routing) | Layer 2 (MAC Bridging) |
| IP Addressing | LAN has its own Subnet (NAT) | LAN is same Subnet as Main AP |
| Main Use Case | Providing Internet to LAN devices | Extending existing Network / Transparent Access |
| Compatibility | Universal (Connects to any AP) | Restricted (Requires WDS on Root AP) |
