    Thought I'd post some pics of my WRT54GS v.2 now that I'm done (are we ever really done?) modding it. All told it cost about $30 for the mods. Time wise.....well....it took a lot of time. I'm anal about attention to detail. Like the small pieces of heat shrink on the internal wiring connections. Anyway, maybe someone can learn by looking and/or get the balls to tackle it like I did.

    They're not cheap and you can get better performance for less dosh.

    Edit : Forgot to say that mod looks absolutely awesome! Do you honestly need extra cooling on a Linksys router (e.g.: my WAG354G) for it to remain stable?

    Well I'm no wireless expert but the Linksys antennas are rated at 5 Dbi for £30, if you look on Broadband Buyer's indoor antennas section there's cheaper antennas that have a higher Dbi rating.

    I got them at Walmart. They're the Linksys 7db High Gain Antennas. They were about $40.

    If you overclock it and crank up the radio output you do. Without extra cooling, OC'ing alone will barbecue it. I've got this one OC'd to 252. At 264 it started acting weird so I cranked it back down.

    Also, the statement that these antennas only come with SMA connectors is incorrect. Mine have TNC connectors to match the WRT.

    Serial port?

    What can be done with it?

    Just out of interest, how did you make up the cable with the IDC connector? Or did you "borrow" it from something else? :wink:

    A proper crimp tool is a bit expensive... Some people have used the IDC cables used for serial ports on old PC's, but these only have 9 wires and pin 10 is not connected which is needed for a Ground. I'm not sure if you could just use the one Ground though (pin 9)

    If anyone's interested in the end I took apart an old IDE cable, pulled off 10 wires in a bunch (the end with the red pin 1)and I put them in a female 10pin IDC header I bought at lunchtime. I just re-used the bits where the IDE header had "pinched" the cable to line up on the new header, and then just pushed the header together and it all seems ok. Continuity on all the wires is ok, and I checked there wasn't any between ajacent wires.

    The only problem is I clamped the wires round the wrong way (doh!), so I'll have to make sure I flip the male header correctly when I solder it onto JP1..

    I made it from "scratch". I make and sell JTAG cables with the IDC connectors, so I invested in a crimper. It was only about $30 from Action Electronics. I had the ribbon cable and a lot of the pins (I have a proper pin crimper too) and connectors already from my JTAG project. I normally use 12 pin IDC connectors for the JTAG cables, so I just ordered a handful of 10 pin IDC's when I ordered my 12 pin ones from Action.

    As to the poster that asked what could be done with the Serial Port. I really don't know yet!! It was a fun project. I can go into my router without telneting in......run commands from there. I can also watch it boot....that's kind of cool watching it load all the stuff. If I brick it, I don't need JTAG to recover it unless I really hose it. If I just need to clear the NVRAM, I can do that via the Serial Port.

    I'm adding a micro SD card next. I want to run a small FTP server using VSFTPD and while I could use my smbshare (on a 37gb hard drive), I want it to be independent from my PC. I have the micro SD card reader and a few cards....up to about 256MB so that should be plenty of room. I'll post pics of that when I'm done.

    Where did you get the serial ports for the mod? I will be using the WRT for a simiar tank project that was featured in ROBOT magazine. I will be using the serial mod for a GPS unit so that I can see the tank on my laptop, also might makeit easier to program some basic autonomous code for it using the GPS module.( I hope)

    I use the AD233BK from CompSys.

    The tutorials are here for the dual port and here for the single port. I did the single port.

    Not sure if this is Kosher or not....if not, the Mods will fix it. For those of you who liked the modded router featured here, it's for sale. I have it listed on ebay for far less than I have into it. I have a couple new projects going, so it was time to move this one along. It still works flawlessly and all mods work as expected. Later.
