Using the "cat /proc/mtd" display my Netgear wndr3700 doesn't show an ART partition, probably related to my trying Openwrt software. Accordingly, there are no wireless tabs in my DD-wrt menus, and the wireless leds are not on.

From the openwrt forums I have the ART binary file, but I need the commands to install it.

The openwrt forum says "place your art partition dump into /tmp, and then: "mtd -r write /tmp/art.backup art"

I know nothing about Unix so I think I need the commands to place the art partition into /tmp (per the above). Do I have to create the ART partiion first?

In summary, please give me all the commands I need to restore the ART partition.

I use Windows and have TFTP, and Telnet. I can log into dd-wrt using telnet.

Thanks

The ART area is not defined as partition in dd-wrt, hence it can not be deleted neither can it be written from within dd-wrt.

Flash back openwrt on the router and repair it there, then flash dd-wrt again if that is what you want to use.

According to some openwrt forum postings openwrt needs to be patched to allow write access, but dd-wrt does not need a patch. So one poster said he flashed dd-wrt and then restored the ART partition and wifi started working immediately. Unfortunately, he did not post enough specific commands for someone with no Linux knowledge (like me).

Thank you.

I found this post in the DD-WRT forum and it sounds like it would fix my problem.

http://www.dd-wrt.com/phpBB2/viewtopic.php?t=164731&postdays=0&postorder=asc&start=15

According to the post the applicable wireless partition can be one of several names (including ART). In my case, I see that it's "board_config", not "ART" as I previously thought.

The post says:

"Use WinSCP to transfer the file via scp to routers /tmp folder.
telnet into the router and issue the cmds:

mtd unlock partionname
mtd write -f /tmp/filename partitionname"


I understand the telnet stuff, but I have no clue what WinSCP is or how to use it to transfer the file to the /tmp folder.

Any guidance will be appreciated.

Thanks
Frank
