Is the Linksys WCG200 router, (wireless-G "cable gateway), compatible with HSMM-MESH, can it be modified to be compatible, or did I just "blow" about $5.00 buying it?

It looks like it will be more work than what it's worth. However, it does look like a pretty nice piece of hardware!

I think it would still be worth trying.  You'd have to use a hex editor to change the first 4 bytes of one of the *.bin firmware files to be what the WCG200 looks for, but since linksys' website doesn't have any firmware posted, I can't even tell you unless I hooked up a jtag cable to the device to download the firmware from the WCG200.

HSMM-MESH won't work with the WCG200. It looks like even getting a compatible firmware loaded would be a LOT of work. There isn't any info I can find, like Flash size or CPU that would indicate anyone has even tried. OpenWRT has a long list of hardware, and it isn't listed. http://wiki.openwrt.org/toh/start#linksys

Barrie,

I actually printed the "shopping list" yesterday, (Sunday), and I didn't see it on that list either, KF5JIM's reply wasn't the best of news, but fortunately I am out less than $5.00 for the hardware, I bought it at a thrift store AND received a Veteran's discount! :) With the "shopping list" I guess to paraphrase the old song I won't get fooled again! At least I now have some spare parts for the junk box, (the two antennae and a 12V 1A "wall wart").

Paul, I guess it pays to keep the "shopping list" handy when you're out looking for the parts, ha ha. I guess on the "upside" I am now ahead two antennae and a 12V 1A "wall wart" for less than either of those items costs to acquire via e bay. :) I love it that, (most of), the local thrift stores give Veterans a 10% discount when we buy from them. Next shopping trip Tuesday, hoping to snag at least 1 of the right routers before I return home.

Where do I get hex editor software and a jtag cable? It may well be time to start getting more used devices made "available for use" as broadband hamnet equipment. I have looked all over Boise, over the last two days, trying to find a suitable unit, (including on Craigslist), it looks like most of the suitable units are either; still in service, already in the hands of other amateur radio operators for use as broadband hamnet equipment, or are in the local landfills, at least in the Boise, Idaho area. There were some Linksys routers, modems, etc. available, but none were the correct versions for broadband hamnet usage. I finally ended up buying a WRT54GS V3 from KJ6WJK on eBay today. I'll probably end up buying at least one more via eBay before I get my version 1 "G cable Gateway" flashed, if it can even be done.

Any hex editor will work. I like portableapps.com's hex editor Frhed because it's free and doesn't require installing (the "installer" just unzips the file).
http://portableapps.com/apps/development/frhed_portable

As for a jtag cable, I have two. I would only use this to force and/or delete the firmware (kernel) on the BIOS flash chip of a bricked router. I have one for a parallel port and one that uses USB. The parallel port one is used in the event the USB one fails (I have had this happen, but that was for a very corrupt router!). For the most part, you will want to use the USB jtag cable.
USB: http://www.diygadget.com/tiao-usb-multi-protocol-adapter-jtag-spi-i2c-serial.html
Parallel: http://www.diygadget.com/jtag-cables/universal-jtag-adapter-v2-wiggler-and-xilinx-platform-cable-compatible-debrick-routers-modems-and-more.html
Documentation: http://www.tiaowiki.com/w/Debrick_Wireless_Router_Using_TUMPA_and_zJTAG

This method is definitely not for the faint of heart, and make sure you know what you are doing before executing anything. It bring routers up from the grave into working condition again. I've purchased cheap bricked routers and used this to get them working again.

For making some non-compatible routers possibly compatible, see one of my previous posts: http://hsmm-mesh.org/hsmm-mesh-forums/view-postlist/forum-2-hardware/topic-257-wrt54g3g-st.html
This makes both the WRT54G3G-ST (W3GS) and WRT54G3G-AT (W3GA) compatible with BBHN eventhough a downloadable firmware does not exist. I currently have a WRT54G3G-ST running mesh just fine.

Let me know if you have any questions.

Paul, Thank you for all the information. I'll take a look, as soon as possible.
