Linksys WRT3200ACM

The WRT3200ACM is part of the wrt_ac_series, with 4 detachable antennas, and a faster dual core processor. It is a dualband, 802.11ac wave 2 (160MHz, no 80+80) capable device.
While only 1 revision of the hardware is listed, silently (around Nov 2017) the flash chip was updated in production causing earlier firmwares to be incompatible with newer devices.

Wifi Driver bug and workaround

In the latest version of OpenWrt starting with 19.x there seems to be an issue with the 5Ghz Wifi driver and 3rd radio that causes issues and drops. To work around it a kernel module needs to be removed and the wifi setting reset so only 2 radios are used.

After a standard installation before setting up Wifi follow these steps, but see the link below to the issue in Github first: 

opkg remove kmod-mwifiex-sdio
wifi config > /etc/config/wireless
reboot

Issue 9956

Please read the “General” section at the bottom of this page, as it contains numerous other issues that affect this router.

Dual Firmware Flashing

The WRT AC series of routers uses a dual firmware flash layout. This means that two separate firmware partitions are included on the device and are flashed in an alternating fashion.

If booting from the primary partition, the secondary (or alternate) partition will be flashed on next sysupgrade, and booting is toggled to happen from that partition. The same logic applies to secondary-→primary. Note that this means there is no permanent “OEM partition” and “OpenWrt partition”. Both firmwares follow the same round-robin logic, where partition usage changes at each sysupgrade. The current firmware always remains as the fallback, and the new firmware is flashed to the other partition.

See the Flash Layout section on each device page for more details, or options to switch between partitions below.

It is recommended to install the LuCI package developed for managing dual firmware luci-app-advanced-reboot.

Firmware Recovery

If the firmware has an issue, chances are you can recover it easily due to the Dual Firmware partition layout, by switching to the alternate firmware. For this reason, it is recommended to always keep a known working firmware on the other partition (either OEM or OpenWrt).

Switch router from primary to alternate partition or vice versa using any of the methods below:

LuCI

  1. Install luci-app-advanced-reboot:
    1. SSH: 
      opkg update && opkg install luci-app-advanced-reboot
    2. WebUI:
      1. System → Software
        1. Actions → Update Lists
        2. Actions → Filter
          1. luci-app-advanced-reboot → Find Package
        3. Status: Available packages
          1. Install luci-app-advanced-reboot

  2. System → Advanced Reboot

Serial

  1. Connect via Serial: 
    reboot
  2. At 3 second autoboot interrupt delay, press any key
  3. Boot
    1. Primary Partition
      1. Armada XP 
        run linksysnandboot
      2. Armada 385 
        run nandboot
    2. Alternate Partition:
      1. Armada XP 
        run linksysaltnandboot
      2. Armada 385 
        run altnandboot

SSH

  1. Determine current partition: 
    /usr/sbin/fw_printenv -n boot_part
  2. Boot
    1. Primary Partition: 
      /usr/sbin/fw_setenv boot_part 1 && reboot
    2. Alternate Partition: 
      /usr/sbin/fw_setenv boot_part 2 && reboot

Power Switch

  1. Power off router with power switch.

  2. Turn power back on and power LED will light.
    1. As soon as all LEDs turn off (~2s), power off router with power switch

  3. Turn power back on and power LED will light.
    1. As soon as all LEDs turn off (~2s), power off router with power switch

  4. Turn power back on and power LED will light.
    1. As soon as all LEDs turn off (~2s), power off router with power switch

  5. Turn power back on and allow router to fully boot.
    • It should now be booted to the alternate firmware partition

Explanation: There is a counter for boot attempts. The counter is increased by 1 at the start of each boot process, then is reset to 0 after a successful boot. If the counter reaches 3, the boot is considered a failure and the boot partition is switched to the other partition (A-→B or B-→A).

Thus, if you interrupt the boot process three times, the router thinks that the current firmware is faulty and switches to the other partition. Note that there is no guarantee that the other partition works. It has the contents and settings that were there when the boot was switched last time, usually at the last sysupgrade. That boot marker switch (A-→B or B-→A) happens at every sysupgrade, so likely you just have the previously used firmware there (either OEM or OpenWrt). But the marker may have been manually toggled, or auto-toggled after three failures.

Serial Port

Synopsis

Serial Port is labeled J1 on the board, utilizing a JST PH 6 pin connector with a 2.0mm pitch, operating at 3.3v

  • The more common 2.54mm pitch will not fit properly.
    • In a pinch, removing the plastic casing from 2.54mm female connectors allows for a stable enough connection.
      • Ensure leads are insulated with electrical tape
  • If flashing regularly, you may wish to invest in a USB-TTL AJ cable
    • USB-TTL AJ cables require installation of a 3.5mm Jack (F) on the router

Using 21.02 or later

  • Use 21.02.2 or later as it has a fix for a serious WiFi crash bug ea91ebedce8051e4a3bf84586b589e918d1fc08c.
  • If you have multiple SSIDs on a single radio, you may encounter issues with the radio not being able to start. To fix this remove any macaddr configuration from /etc/config/wireless Forum discussion

Reset wireless configuration to working defaults: 

uci set wireless.radio0.channel='auto'
uci set wireless.radio1.channel='auto'
uci set wireless.radio2.channel='auto'
uci del wireless.default_radio0.macaddr
uci del wireless.default_radio1.macaddr
uci commit wireless
reboot

Disabling AMSDU:

Add to /etc/rc.local before exit 0 to disable AMSDU on each startup, the logger line is not required, but useful when looking at the syslog to make sure the command was run on startup. 

echo 0 > /sys/kernel/debug/ieee80211/phy0/mwlwifi/tx_amsdu
echo 0 > /sys/kernel/debug/ieee80211/phy1/mwlwifi/tx_amsdu
logger "AMSDU Disabled"

General

  • Firmware builds for the 22.03 series beyond 22.03.2 do not exist due to a bug see broken MV88E6176 switch. Build are available as normal for 23.05 releases.
  • WPA3 will not reliably work due to mwlwifi issues. In certain circumstances it can crash the router completely. Don't enable it, use WPA2 only.
  • Do not enable 802.11w Management Frame Protection, mwlwifi does not support it properly. It is disabled by default.
  • It is strongly recommended to use auto or channel 36 on radio0 (5.0 GHz) to avoid crashing the WiFi chipset. Forum discussion
  • Certain embedded devices don't work with the 2.4 GHz radio unless LDPC is disabled. GitHub issue
  • It has been reported that the 5GHz radio crashes periodically if the irqbalance daemon is installed and enabled.
  • It is suggested to enable packet steering to work around hardware scheduling1)2) issues.
  • Some time around November 2017, Linksys silently updated the hardware for the WRT3200ACM, but did not change any version numbers or other identifiable labels. In particular, they changed the flash memory chip, which resulted in older firmwares causing bootloops on these new devices. This has since been fixed.
  • You may find additional/supplementary information at the wrt_ac_series page
  • Tested OpenWrt 19.07, no issues found, very stable
