Ran across this just a couple of days ago, a USB Wifi the size of a wireless mouse dongle for $13:

without a proper antenna, I wonder what sort of range you can get with one of those.

I have one here. Mine happens to be 802.11n and has a Broadcom BCM5800 inside it. On some equipment, it works better on a 10cm USB extension lead. Generally, the range is approximately equal to my Dell Latitude E6410 laptop.

Depending on your exact application, you could always try and make a signal booster - I came accross this design the other day, made from a beer can:

Nice, does it work well? My router is on the other side of the house, so to get a decent signal I have to get the antenna in just the right spot... might give the beer can thing a go.
Thank you

We have a pretty wireless-opaque house, and use a Pringles can-tenna to surprisingly good effect. http://en.wikipedia.org/wiki/Cantenna

Eben spent a year or so at an Intel research lab which was basically a giant Faraday cage, with a very high-bandwidth variation of the same thing pointing directly at his...reproductive system. We've yet to experiment and discover whether it did any lasting damage.

A cheap Deal EXtreme Wifi dongle could do the job. The real issue is to configure it.

Yep, dealextreme are a pain for that because they rarely specify chipsets, and change models on the fly w/o warning.

I just ordered a few from buyincoins.com to test:

http://www.buyincoins.com/deta.....-1644.html
http://www.buyincoins.com/deta.....-1916.html
They all support Linux (using realtek RTL8188CU chipset) and approx. 7 USD, including shipping.

Would it be worth it to try to validate and source a combo Wifi + Bluetooth dongle ? It looks like they could be cheap in quantity ($1-2 FOB on alibaba, $16 on Dealextreme), and be very handy especially for Model As. Possibly saving a hub, which is very convenient and helps cover the extra cost for BT instead of USB KBMS.

I wanted to pipe music wirelessly from my playroom into the garage. The garage has *loads* of iron in it and, as any Prattchet fan will know, "you can't magic iron".

The solution was a cantenna. In my case, it was made from a whiskey can. (I'm sure that I'd get a few dB over a *Pringle* can.) It works well but is *very* directional.

Regards,

Mark.

P.S. I have a use for the RasperryPi that will entail the need for long-range(ish) comms. Unfortunately, the 'Pi will need to be encased in 10mm steel plate and, thus, will be in a tiny Faraday cage. I'm hoping that a really *large* WiFi antenna on the back on my Defender will enable the range I need...

We've yet to experiment and discover whether it did any lasting damage. Cantenna units are fantastic, very directional but worth the effort. I wonder if it would be worth attaching a cantenna to a pair of continuoud rotation modded servo motors, then make it find the best signal for you?

If you check the wiki (there's a link in my sig) it has two wifi chipsets that have been tested and confirmed to work with the r-pi. Once you know the chip name that's works, a simple google search should help you discover whether or not your wifi dongles are compatible (at this point, I'm sure more and more chipsets will find their way onto the working list as time progresses ;) )

$8-$9 incl. shipping here http://s.dealextreme.com/searc.....o+usb+wifi

This is a good one, it's said to have out of the box support with most Linux distros aswell. It's built of the Ralink chipset 5370.

I will definetely go for this one! :)

I bought a few of the very small usb wifi dongles from dealextreme with the thought of using them with Raspi. My windows machines took them fine but the range is horrible. May be just good enough for my application. buyer beware.

eh, such things will naturally come about one the r-pi is in our hands ;) Right now they have enough on their plates to get it all finalized by the end of November deadline.
