CradlePoint 3.2.4 Firmware Released with USB551L Support for CBR400, CBR450, CTR35, MBR95, and MBR1400

Today, Cradlepoint released firmware version 3.2.4 for their NetBSD-based routers which include the CBR400, CBR450, CTR35, MBR95, and MBR1400. This firmware release provides additional modem support for a few different modems but most importantly the Novatel USB551L 4G USB modem on Verizon’s network.

The complete list of changes are available in the release notes. The new features listed are:

  • New modem support added.
  • Includes improved LTE driver support, allowing better connectivity.
  • WiFi-as-WAN change. If the WiFi is configured for 20/40MHz operation but the user configures the router for WaW, force the WiFi to 20MHz operation only.
  • GPS support added for use with modems that support GPS location. (additional details in the release notes)
  • New WiMAX driver to support additional WiMAX modems.

The following bugs are listed as fixed from the 3.2.0 release:

  • If any of the router’s WAN connections (Ethernet, Wi-Fi as WAN, modem) connects to a device that has the same IP subnet as the router, the router will disable the interface and provide a Bounce Page warning that the WAN interface has a conflict. Simply change the LAN IP Address on the Network Settings –> WiFi / Local Network Settings page in the UI.
  • Sierra Wireless 598U did not work correctly on USB port #3 on the MBR1400.
  • Defects in detecting WAN failure conditions have been fixed, allowing better Failover performance.
  • Issues in VPN with WAN interface failover
  • Improved failure detection for WAN failover and failback
  • Defect in WWAN profile upgrade from earlier firmware versions. Users should be able to upgrade from 3.0.x or 3.1.x to 3.2.2 or 3.2.4 and keep their WWAN profiles.
  • No longer show disassociated WiFi clients under LAN section in the Clients List.
  • A defect seen while Load-Balancing with multiple modems was fixed.

I have experienced some load balancing and failover quirks with the MBR1400 running firmware 3.2.2 that I will be further investigating but so far performance has been excellent and I expect 3.2.4 firmware release to correct most or all of the quirks.

I have confirmed that the USB551L now works very well on the NetBSD-based routers. My testing was specifically with the CTR35 but I will also be testing with the MBR1400 shortly. The firmware release can be downloaded through the web interface of any of the routers or manually from the Cradlepoint web site.

With support for the USB551L, the Cradlepoint NetBSD-based routers now support all the major USB modems on the US market. I highly recommend any of the new routers such as the MBR1400, MBR95, CBR400, CBR450, or CTR35.
