Topic: Netgear WNR100 v2

I just received a nice new WNR100 v2 and I've opened it up to find:

* a cpu covered by a heat sink
* 256Mb ram chip (32MB)
* Atheros ar9285-AL1A wi fi chip
* no byte wide flash
* a serial flash chip - 25L3205DM2I-12G (32Mb or 4MB)

I also found the Netgear Open source software page. Looks like I have a chance to get OpenWRT running on this router. :-) Has anyone already done it?

Re: Netgear WNR100 v2

No, as we don't have access to the board. The cpu should be an AR7240, so if you decide to add support for it, use the ar71xx target as a base.

Re: Netgear WNR100 v2

Thanks, that's what I hoped for, a little shove in the right direction. :-)

Re: Netgear WNR100 v2

It's probably the same hardware as Netgear WNR1000 v1, Trendnet TEW-632BRP and D-Link DIR-615 revision C1. These routers are all virtually identical based on the Atheros AP81 router platform with Atheros AR9102 WiFi chip (2x2 MIMO).

This router is probaby already running OpenWrt. Try login with Netgear Telnet Enable Utility.

http://www.myopenrouter.com/download/10 … e-Utility/

Working snapshots for this platform can be found here.

http://downloads.openwrt.org/snapshots/trunk/ar71xx/


You can probably download an image with ftpget and flash with mtd write like this example.

ftpget ftp.iasi.roedu.net /var/firmware /mirrors/openwrt.org/snapshots/trunk/ar71xx/openwrt-ar71xx-ap81-rootfs-squashfs.bin

mtd unlock mtd2

mtd write write /var/firmware mtd2


Maybe someone else can give you exact instructions how to upgrade your router.

Re: Netgear WNR100 v2

I have the same model (WNR1000 V2) and would like to make it as Wireless Bridge so that I can use for Sony Bravia TV.

what image are you using ? http://downloads.openwrt.org/kamikaze/7.09/

Do you think it works with version 8.09.2 ?

How can I install and config from windows machine. I tried telnetenable tool  but it didn't work.

Thank you for your help.

Right now I'm still on the stock firmware. I was hoping to get a backup copy of the firmware before I started but I've not found any yet. I'm hoping I can backup what's already on there first. THen attempt to compile the Netgera firmware (which is just OpenWRT 7.09 that I downloaded from the Netgear site). I don't want to just into this without some investigation first.

Do you think it works with version 8.09.2 ?

I haven't tried it yet but I don't if there is a version that will work with it.

telnetenable ???

Re: Netgear WNR100 v2

Please excuse my ignorance if I ask stupid questions. I'm still in the learning curve wink

I found the thread shows how to config Kamikaze in client mode and just wondering if the router is currently running  Kamikaze 7.09, then can we just change the config to make it a wireless bridge or we have to re-complied to get a new firmware?

https://forum.openwrt.org/viewtopic.php?pid=52024

Thanks!

Re: Netgear WNR100 v2

Any news on this. I have one of these devices. I've got to setup windows machine to enable telnet into it, but I would like to upgrade it to a newer version of OpenWRT

Re: Netgear WNR100 v2

So I have just received a brand new wnr1000v2 VC.

I do not know what the VC indicates but I can only find people relating it to Comcast. That is how I got mine, for free.

As posted previously the router has an ar7240 CPU. The wireless chipset shown on the fccid pictures and posted by the original is ar9285-AL1A which is confirmed from the bootlog as an AR9285.

I confirm that telnetenable works. I am not able to change the password with the passwd command. The passwd file is read only. I could not find a text editor installed ( tried vi, vim, nano, and pico).

I have tried building from trunk svn 21527(I think). I could not get it to build with ar71xx and madwifi. But that probably my fault and for another topic.

I had a successful build from the imagebuilder-ar71xx-for-linux using backfire 10.03. I do not know if this will work because I do not know how to make the .img headers so it can be installed from the web interface.

I am going to attempt to do a tftp on boot using the tftp.exe application I found on the dd-wrt website. The build is from the image builder with the default profile and packages kmod-ath9k, wpad-mini, and luci. I do not know which of the images would be preferred so I will probably pick on at random.

I assume that if this fails I will be able to restart to normal or tftp again with a firmware from the netgear website.

Worst comes to worst I can just call comcast and say it died. lol!

Re: Netgear WNR100 v2

Guess I will not be. All the images prepared by the image builder are for specific routers.

I am now stuck. Any suggestions on where to go?

Re: Netgear WNR100 v2

I also have a wnr1000v2-VC i'd like to update... has anyone cracked this yet?

Re: Netgear WNR100 v2

ncherry, any updates on this?

Re: Netgear WNR100 v2

I am also very much interested in getting this Netgear WNR1000 v2 to work as a bridge !!

Re: Netgear WNR100 v2

I'm thinking that if you just change the value in the file /module_name from WNR1000v2-VC to WNR1000v2 (or maybe WNR1000v2-NA) you should be able to get past the module name check and just use the firmware update page to upload WNR1000v2-V1.0.1.1NA.img

Unfortunately the squashfs filesystem on /dev/root is marked read-only and it's not a symbolic link to a writable file. I haven't been able to figure out how to use mtd to temporarily mark the filesystem read-write so that I can change the /module_name using cat. If anyone can explicitly spell out how this might be done, it would be very helpful.

My next step is to compile the 1.0.1.1 firmware but change its module name check to WNR1000v2-VC so that it uploads correctly.

Re: Netgear WNR100 v2

while looking things over earlier today, i noticed that the GPL firmware src on the netgear site has very few almost miniscule differences between the WNR1000v2-VC and the WNR1000v2. Most of which can probably be contributed to the software version differences.
           (downloaded both and looked through everything with winmerge)

The most notable difference is the addition of some files in the VC version, mainly custom configs, and patch files, and more importantly, the declaration of the module version / name in the makefile.. (I'm sure if i dig a little further, can figure out where and how to disable the rejection of non-VC firmware, doing this once, should allow us to flash a different version)
an easier example to get the latest netgear firmware for the WNR1000v2 on the VC version would be to download the GPL source for the normal v2, and simply tack on the " -VC " at the end of the module name declaration line here:
line#: 9
File Location:

WNR1000v2_V1.0.1.1_gpl_src/target/linux/wnr1000v2-2.6/image/Makefile

by doing so, you should be able to flash the device with normal WNR1000v2 firmware, and forgo the outdated VC version that doesn't seem to be actively developed anywhere.

now i haven't tried this as of yet, but worst case scenario, you'de have to send the router back to comcast as non-functional. If i remember right, i read somewhere that they will provide postage to ship it back.. or you could go to your local office and say " it stopped working, can i get an exchange "

Re: Netgear WNR100 v2

I am interested in trying to upgrade mine as well.. Let me know if you have any luck getting new fw on the VC version as I'm tired of having to reset router a few times each day because of disconnects.

Re: Netgear WNR100 v2

Can anyone build a firmware image for me from the following NETGEAR GPL source code?

NETGEAR WNR1000v2-VC: ftp://downloads.netgear.com/files/GPL/W … pl_src.zip

The recommended build environment is Ubuntu 8.04, but I have Ubuntu 10.10 64-Bit. I'm not sure if I'm experiencing the make errors because of the GCC version but it exits during the preparation stage. I've tried different GCC versions 4.1 and greater but none have shown a different outcome. I would appreciate it quite a lot, if someone would attempt it and then provide me their results. I'm wanting to revive my bricked router and hopefully work on building a firmware from the Atheros AP81 branch to test. Thanks for your help.

Re: Netgear WNR100 v2

I have acquired the WNR1000v2-VC V1.0.0.3NA firmware that can be used for recovery of these particular routers which were provided by Comcast. I attempted building the firmware in different Linux environments according to the instructions included with the GPL source code and it ended prematurely with GCC errors. After 3 weeks and 3 tiers of support, I received the firmware from Netgear. It took an "engineer" to provide me with the firmware which none of technical support could provide. This was the most horrible technical support provided by a company that I've ever experienced, especially for such a simple request of wanting the firmware for THEIR GPL source code.

I uploaded the firmware image at the DD-WRT forums. The subject for the thread is "NetGear WNR1000v2 Request".

DD-WRT: http://www.dd-wrt.com/phpBB2/viewtopic. … p;start=15

MultiUpload: http://www.multiupload.com/H3GJQCSE65

SpeedyShare: http://www.speedyshare.com/files/252260 … .0.3NA.zip

GENERAL WARNING: NETGEAR or COMCAST has modified the U-boot boot-loader and it will not boot any firmware images above V1.0.0.3 for the WNR1000v2. Hence, the added -VC to the model number. I know this because I was able to modify the header of the firmware image for V1.0.1.1 for upload to the router and it detected a corrupt kernel. According to NETGEAR technical support, the router hardware for the WNR1000v2-VC and WNR1000v2 are identical. So, if anyone has the U-Boot boot-loader for the WNR1000v2, then could you share it or retrieve a copy from your router? Also, once I have the U-Boot image then is there a way to change the boot-loader, other than JTAG? I don't believe this unit has the interface.

Re: Netgear WNR100 v2

Is there any update to this? I just found one of these routers in my closet and would like to put OpenWrt on it.

Re: Netgear WNR100 v2

I'm sorry to bring up what appears to be a dead thread, but I've been trying to get OpenWRT on this router and I've made some progress I wanted to share. So first of all, I have the WNR1000v2-VC version that was handed out by comcast. I'm not sure what the differences are between the VC and normal version. Someone above me mentioned something about not being able to upgrade the firmware, but I downloaded v1.0.0.12 from netgear's site and was able to update to it. In any case, what I really want is OpenWRT running on this router. Towards that end, I've actually made some progress, and I have a WNR1000v2-VC-OpenWRT.img file you can upload through the router's web interface. It boots the OpenWRT kernel but right now I'm stuck trying to determine the correct boot arguments. But before I get to that part, let me tell you guys how to build the image file yourselves.

First, download and extract the GPL sources from netgear;s gpl source site. I used this toolchain http://www.downloads.netgear.com/files/ … l_src.zip. Now, I wasn't actually able to compile any kind of firmware with this toolchain, but that's not why we need it. The important parts are the programs in the 'tools' directory. Follow the build directions in the toolchain and make changes as needed (I had to make several, and unfortunately I didn't document some of them) until the mkimage and mksquashfs-lzma programs are built. That's all you need from this toolchain.

Next, checkout the latest OpenWRT attitude_adjustment toolchain from subversion. I configured the toolchain using the console based menu, but for brevity here's a tinypaste link to the configuration file I used http://tny.cz/04cc1b8b. Go ahead and build the images using "make". Now what we have to do is use the filesystem tools from netgear's toolchain to assemble an image containing the kernel and rootfs created by the OpenWRT toolchain. Here's a script I wrote to accomplish this. Make sure to update the NETGEAR and OPENWRT variables to point to the respective SDKs.

rm head.pad head_info.pad

# create the firmware image
cat header.bin rootfs.bin > firmware.bin
./appendsum firmware.bin ${MODULE_NAME}-OpenWRT.img

Please note that for right now the kernel load address (KERNEL_LOAD) is hardcoded into the script. I'm not sure if there's a way to auto-detect it, but I got that address from the output of the 'readelf -a vmlinux.elf' command. Once you run this script, you should have a file 'WNR1000v2-VC-OpenWRT.img'. You can upload that through the router's firmware upgrade page.

Now here's the part I'm stuck on. The kernel boots but can't find the the root partition. Here's a tinypaste link to my boot log http://tny.cz/3e8f1d20. Obviously, the boot arguments that worked for the netgear firmware aren't working for OpenWRT. I've tried to omit the root and rootfstype options hoping for some kind of auto-detect, but I get the same error (with block (0,0)). I've also tried guessing several variations, and no luck there either. Guys, we're like one step away from running OpenWRT on this router, and I could use your help.

Does anyone have any idea how we can find out the proper boot arguments to use? Also, if there's an OpenWRT developer reading this, I'd like to eventually update the OpenWRT image builder to make proper images for this board (hopefully without the outdated utilities from the netgear dsk), but I don't know how to go about doing that. Help!?

Re: Netgear WNR100 v2

Ok, well I've done some digging, and it seems there's more work to do than I first though. We need to add support for a new device following http://wiki.openwrt.org/doc/devel/add.new.device. My only gripe is that the page seems to be somewhat out of date. I picked the latest support revision I could find in subversion (https://dev.openwrt.org/changeset?sfp_e … sfph_mail=) and I'll be working off that to try and add support for this board. I've extracted some information about the router from uboot, namely the flash layout, so I'll start working to add support to the openwrt build system for this board. My first goal is to get the kernel to boot. Then I'll worry about all the nice hardware like ethernet interfaces, leds, and other things. Lastly, we'll have to add support for building firmware images for these kinds of boards. I've subscribed myself to this topic, so if anyone with development experience (in particular with this not-so-fully-documented-openwrt sdk), I would appreciate the help.

Here's some of my notes on the board's flash layout http://tny.cz/59e75343 and a work-in-progress mach file http://tny.cz/8d5d8064. Hopefully, this thread won't die again until we've added hardware support for this board smile.

Re: Netgear WNR100 v2

Have you m ade any further progress with the WNR1000 V2? I have one as well (from comcast) and would like to openwrt.

Thanks

Re: Netgear WNR100 v2

I don't see how something as complicated as the PS3 can be hacked to run custom firmware, but this POS router from Comcast is somehow bulletproof? Wish I was more l33t!

Re: Netgear WNR100 v2

I don't either. I have the v2 WNR1000. I ordered a Xilinx USB jtag cable that should be here tomorrow, but I'm not much of a hacker. neutral
