WUSB54G High-Gain antenna mod

    Sick and tired of crappy reception I altered my WUSB54G v2.0 (I know the "board" says 4.0 but the "device" is v2.0) to be easily attached to an external antanne via an SMA connector.

    I have got version 4 of this adaptor (says version 2 on the board), and the soldering for where the antenna is located has been removed but there is also another 'metal' material which cannot be removed or melted. Any ideas?

    Also, wheres a good place to get the items you used to mod yours - the cable used to connect to the SMA inside the adaptor and the high gain antenna?

    Thanks.

    A v4 adaptor is quite desirable because apparently its not a broadcom chipset, its supposedly Atheros or some other chipset that has open source drivers. Its listed in the OpenBSD 3.6 manpage as supported so thats where I get this idea from =D

    I'm going to need to see a high resolution image to know more about what you are seeing. You'll either need to locate a better image perhaps on the web ala Google, or take one yourself otherwise I just can't tell from the photo you uploaded.

    I guess it depends on where you live. I buy most of my parts from MRO Electronics in Vancouver, B.C. (Canada). There are a variety of on-line resellers that you can order from, but I really hate waiting, its nice to get something local.

    The cable I used and the SMA connector attached to it actually came from another device that someone ran over or dropped or otherwise rendered inoperable so I just shortened it and soldered it on, but one could easily make the same cable by purchasing the parts.

    The SMA adaptor I'm using is an RP-SMA attached to an unknown gauge of likely low-loss cable, its about as thick as the stuff inside of a WRT54G/GS used to attached to the second RP-TNC antenna jack.

    The black 7" antenna is the antenna that came with an early model Linksys 802.11b PCI card, sure wish they shipped those antennas these days... The 18 dBi directional waveguide antenna shown last is an antenna that I make and sell. Its similar in design to the pringles can style design only substantially larger and weather proof.

    Cheers,

    James

    i tried this mod but i could not get the wusb54g original antennas wire out.

    i could not unsolder it. i am using a coldheat maybe that is why, cant get my hands on a real solder iron :cry:

    Same, I'm having real trouble with this part. The solder has been removed but it is still awkward to work around with that other metal still there, it needs to be removed so that I can have clear contact with the tiny connection board.

    That is your problem. You will need a good 25 or 35 watt iron to get that ball to come undone. Cheap soldering irons are just that cheap, and also easy to find. I bought a 25 watt iron from Radio Shack for $9.99 CDN. I have a cold heat also, and I know it was more than that although I didn't pay for it, it was a gift, but its useless for desoldering, for that I have a desoldering iron =D

    Cheers,

    James

    Call me a 'ShackAddict' if you must, but in reality, almost all of the parts in the picture below were purchased from RadioShack because they were cheap, and they all work. A couple of them are missing tips because I've worn them out. The el cheapo $9.99 one I originally bought back in '98 when I was modding Sony PSX. I've been wanting a nice $300.00 Weller or other nice soldering station, but its just too hard to justify that cost when you can get "enough" out of a $10 iron.

    yeah cold heat is kinda stupid mine sticks too. the tip gets worn out quickly.

    Ground for the coax shield connection to a WUSB54GS

    Where are you connecting the shield of the coax to. I need to run my short piece of coax to a 19db gain antenna with a N connector. As soon as I find out I'll velcro the WUSB54GS on the back of the antenna with about 6 inches of coax.

    under the rubber feet there is a screw.

    Please, any notes on connecting the SMA cable? It's just one wire and ground, right?

    wire to SMC

    Hi,
    and is it possible to connect the wire of the original antenna to the SMC connection? I mean without touch the board.

    thanks a lot for your answer

    Hi all
    What type of cable is needed?

    My mod, the antenna/SMA connector was removed from a D-Link DWL-G510 that died.

    NOTE: ignore the empty hole. I was going to put the SMA connector here but the small cable would not reach properly.

    Coldheat irons that bad! Nearly bought one, an electronics chain store as they were selling loads off dirt cheap, 1/3rd the normal price, I know why now.
