 +====== Buffalo WHR-G54S ======
 +| {{:​meta:​icons:​tango:​48px-construction.svg.png|}} | Please migrate info from: \\ http://​wiki.openwrt.org/​oldwiki/​openwrtdocs/​hardware/​buffalo/​whr_g54s \\ http://​wiki.openwrt.org/​oldwiki/​openwrtdocs/​hardware/​buffalo/​whr_g54s/​sd_mmc_hack \\ And complete this article. |
  
 +The WHR-G54S is a 802.11g wireless router with a 5 port programmable ethernet switch which supports VLANs.
 +
 +===== Hardware Highlights =====
 +^ SoC ^ CPU speed ^ Ram ^ Flash ^ Network ^ USB ^ Serial ^ JTag ^
 +| Broadcom 5352 |  200 MHz  | 16MiB | 4MiB |  5 x 1  | Yes | Yes | ? |
 +
 +
 +===== Installation =====
 +
 +The WHR-G54S runs a tftp server at 192.168.11.1 on the LAN interface during the boot process. OpenWrt should be installed via TFTP, [[doc:​howto:​generic.flashing.tftp|follow the instructions in the HOWTO section]]. ​
 +
 +If the device has been installed with OpenWrt in the past, it is possible that (somehow) the tftp server address is set to 192.168.1.1 (mine was)
 +
 +
 +In the past there have been some reported problems with the 2.6 kernel versions but these appear to be resolved. Although Attitude Adjustment 12.09-rc1 does appear to run on this router it is extremely slow.
 +
 +Now officially Trunk and AA are not supported for this router
 +(from Attitude Adjustment announcement) "Lower end devices with only 16 MiB RAM will easily run out of Memory, for bcm47xx based devices is Backfire with brcm-2.4 recommended"​
 +Backfire 10.03.1 (suggested previous to my edit of this wiki) provides a more acceptable level of performance.
 +
 +The base trunk as of r36656 will OOM this router at boot time, even without wireless drivers loading (https://​dev.openwrt.org/​ticket/​13558)
 +
 +In any case the generic brcm47xx image should be used. The filename for that image will be something like openwrt-brcm47xx-squashfs.trx
 +
 +===== Upgrading OpenWrt =====
 +This device can be upgraded via LuCI.
 +
 +===== Switch Ports (for VLANs) =====
 +
 +Numbers 0-3 are Ports 1-4 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 5 is the internal connection to the router itself.
 +
 +^ Port             ^ Switch port   ^
 +| Internet (WAN)   | 4             |
 +| LAN 1            | 0             |
 +| LAN 2            | 1             |
 +| LAN 3            | 2             |
 +| LAN 4            | 3             |

 +==== Opening the case ====
 +
 +**Note:** This will void your warranty!
 +
 +  * Remove the Torx screw under the bottom label
 +  * Gently tear off the bottom cover
 +
 +==== Serial ====
 +
 +There is a serial port on the main circuit board which uses 3.3 Volt RS232 interface. Please make sure you have the correct equipment to interface to a 3.3V serial port.
 +
 +==== Buttons ====
 +
 +The Bufalo WHR-G54S has one push buttons (AOSS), one Reset Button and a toggle switch (used to toggle btween router and bridge mode when using the Buffalo original firmware).
 +The author has not tested these yet.
 +
 +===== Recovery =====
 +
 +During powerup the Router is configured as 192.168.11.1 for a few seconds and listens for a TFTP transfer. This can be used to re-load firmware.
 +
 +===== Known Problems =====
 +Enabling wireless on this device causes the realtime load average, wifi, and active connections graphs to stop working as well as causes multiple entries of the following in syslog 'Dec 21 23:14:02 BuffAP kern.err kernel: [ 401.460000] NOHZ: local_softirq_pending 08'
 +see [[https://​dev.openwrt.org/​ticket/​10651]]
 +
 +Additionally,​ trying to go into recovery mode presents you with a router that will not have networking
 +see [[https://​dev.openwrt.org/​ticket/​7502]]
 +
 +And, Finally, trunk builds as of 19 May 2013 (r36676) will cause OOM if you enable wireless using either the open or proprietary drivers.
 +No bug filed yet.
