Wikidevi Notes[edit]

This device is Broadcom based. OEM Arcadyan. Not bundled with DD-WRT, but work has been completed to support the device, see this thread for the latest test build

On the OpenWrt wiki

Per the lspci dump, the BCM4360 in this device has the PCI ID of 14e4:43a2

Review on SmallNetBuilder, part 1 and part 2

10:6F:3F OUI
The Arcadyan model of the device may be WG9116AAC-J6.
"P/N: 141911620002J R01" (w/ an RoHS logo to the right) appears to be silkscreened on the main board.
"P/N: 141883320008J" is silkscreened on the BCM4360 wireless module.
The silkscreened manuf. date code is 1215 (third week of April, 9th to the 15th).
Default SSIDs appear to be BUFFALO-XXXXXX_A and BUFFALO-XXXXXX_G (upper case letters, LAN MAC is probably the MAC used for both)

On the DD-WRT forums, and another post with the initial test build

"P/N: 141911620002J R0A" is silkscreened on the main board, per the FCC photos.

.. and "P/N: 141883320000J REV:0A" is silkscreened on the BCM4331 wireless module in the same photos.

The BCM4331 wireless module uses 3x Skyworks (SiGe) SE2594L (Dual Band 802.11a/b/g/n Wireless LAN Front End). The BCM4360 wireless module uses 3x Skyworks (SiGe) SE5003L (5 GHz, 23dBm Power Amp w/ Power Detector).

Serial Recovery[edit]

USB Info[edit]

DD-WRT USB[edit]

The USB port is where you can connect an external USB hard drive or flash drive. Which can do a multitude of things. You can use in as a NAS, storage for a FTP server, use Optware to run external programs like torrent software, samba for sharing files to your network, share a USB printer with your network... The list of possibilities is long, it just takes a little research.

ProFTPd is included in most the newer builds of dd-wrt. Check the features chart to be sure.

Notes[edit]

jffs Issue in DD-WRT[edit]

This problem is caused by the firmware encountering an unmarked bad block during an erase operation while attempting to setup a JFFS2 filesystem on device /dev/mtd/4.

Most people will probably never experience this problem. The AC66U, the D1800H, and the Buffalo WLI-H4-D1300 Media Bridge use the same Samsung flash memory chip. In my case, 4 of my 5 D1800H's had the problem but my D1300 didn't. Neither of my AC66U's had the problem. One person on one of the AC66U threads reported having the problem; here's a link to his post.

If you have the problem, you will not be able to create or copy directories and files to /jffs. Here are some example error messages:(this list was shortened to save space - it can go on for several pages)

[email protected]:~# dmesg|grep jffs
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x05ee0020: 0xe952 instead
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x05ee0024: 0x0e6d instead
jffs2: Further such events for this erase block will not be printed
jffs2: Old JFFS2 bitmask found at 0x05efc7fc
jffs2: You cannot use older JFFS2 filesystems with newer kernels
jffs2: Cowardly refusing to erase blocks on filesystem with no valid JFFS2 nodes
jffs2: empty_blocks 379, bad_blocks 1, c->nr_blocks 760

Also the Status -> Router webpage will show that JFFS2 has no free space.

To fix this problem try the following at a command line prompt:

flash_erase -j /dev/mtd/4 0 0 && reboot

This command erases and marks bad any bad blocks encountered so that they can be "skipped" and formats the partition to JFFS2 specifications. I believe the firmware uses the mtd erase command which seems to fail at handling bad blocks. The flash_erase command needs to be run only once.
