Our new SPR PoE+ router, built on the Raspberry Pi CM5 platform, delivers great performance. In this test, we pushed packets to the limits by running simultaneous throughput tests on both the 2.5 Gbps Ethernet port and a 160 MHz WiFi 6 connection, achieving a combined throughput of over 3 Gbps.

The CM5 exposes a single Gen 2 PCIe lane (Gen 3 can be configured). The SPR PoE+ router splits the lane with a Gen 2 2:1 ASM1182e packet switch to share between the WiFi AP and 2.5GbE port, and a key question has been how the packet switch setup fares under real world conditions.

Hardware Overview​

The SPR PoE+ router features:

• CPU: Raspberry Pi CM5 Carrier Board with CM5104032 (4GB RAM, 32GB eMMC, WiFi)
• Connectivity:
  • MT7916 3x3 802.11AX WiFi 6
  • 1x 1Gbps Ethernet port, 1x 2.5Gbps Ethernet port
  • 2x USB 3.0 ports, 1x USB 2.0 port
• Power: PoE+ (802.3at) capable on 2.5 Gbps port, USB PD Power
• Antennas: FlexMIMO Antennas from Laird

Test Setup​

Our test configuration consisted of:

• WiFi Client: M2 MacBook Pro with 2 spatial streams and WiFi 6 capability
• Wired Endpoints: Two routers with R8125 2.5GbE cards
• Network Path: Connected through two separate 2.5 Gbps switches with jumbo frames enabled on both ends
• WiFi Distance: 6 feet between the MacBook and AP
• WiFi Configuration: 160 MHz channel width, 2 spatial streams, WPA3, DFS Channel 100; RSSI -45

SPR's WPA3 Multiple Passwords per SSID Surprises People​

WiFi nerds and people working on WiFi products have shared their surprise with me a few times now about the integration for multi-PSK with WPA3. This is something already mostly built into HostAP so it should be possible anywhere, although it is not obvious from the documentation. I'm told that most other projects simply don't do it, putting SPR at the head of the pack! In this post I'll share how it's integrated, so that others can benefit from the ideas and improve WiFi security for people all around the world.

Intro​

In this post we'll cover how to configure hostapd with the mt7915 to run 160 MHz channels over 5ghz. This allows stations to break gigabit speeds for WiFi with only 2 spatial streams.
