If any of you are looking for tested WiFi dongles which we know will work with the Raspberry Pi, check the [url=http://elinux.org/RaspberryPiBoardVerifiedPeripherals#USB_WiFi_Adapters]relevant bit of the wiki[/url].

ETA - I\'m pretty impressed that we\'ve managed to keep the forum going for as long as we did before having to block anybody, but sadly this fella\'s broken our run of good forum karma. I have plonked him (for great justice, according to his chosen user name).

Yay! For this day and age of the internet, that was a good run without any of \'those people\'. Now if only you could do the same for the rest of the WWW.

We must be pretty close to hitting the [url=http://en.wikipedia.org/wiki/Godwin%27s_law]Godwin\'s Law[/url] limit on the forum. Get your banstick ready Liz (or redirect them into the kill-and-smoke-a-poor-defenceless-piglet thread to be accidentally \'charcuteried\').

I\'m, thinking of something like one of these little cuties for the PI

We will have to ensure there\'s compatible Linux drivers for the chipset of choice before we buy,
but it shouldn\'t be a problem as wireless adapters have really great support on linux (possibly driven by the appeal of BackTrack ;)

That\'s a nice little dongle, but is it n only?

Chipset: rtl8192cu (Realtek)
Linux support: http://linuxwireless.org/en/users/Drivers/rtl819x
This driver is currently in staging tree and not included into mainline kernel. It was tested on Linux machines and confirmed to be working by Dealextreme buyers.
I can\'t find information regarding Master/AP (Access Point) mode. It looks like driver it supports cfg80211/nl80211.

I would probably go with this one: http://www.dealextreme.com/p/ultra-mini-nano-usb-2-0-802-11n-b-g-150mbps-wi-fi-wlan-wireless-network-adapter-black-71905

Chipset: rt5370 (Ralink)
Driver source can be downloaded from ralink support website (Windows/Mac/Linux).
This chipset *might* support more modes.

Just grepped source code of the latter, supported modes:
NL80211_IFTYPE_STATION
NL80211_IFTYPE_ADHOC
NL80211_IFTYPE_MONITOR

Full list of possible modes:
/include/linux/nl80211.h
765 * @NL80211_IFTYPE_ADHOC: independent BSS member
766 * @NL80211_IFTYPE_STATION: managed BSS member
767 * @NL80211_IFTYPE_AP: access point
768 * @NL80211_IFTYPE_AP_VLAN: VLAN interface for access points
769 * @NL80211_IFTYPE_WDS: wireless distribution interface
770 * @NL80211_IFTYPE_MONITOR: monitor interface receiving all frames
771 * @NL80211_IFTYPE_MESH_POINT: mesh point
772 * @NL80211_IFTYPE_MAX: highest interface type number currently defined

Well in that site (I don´t know if I can post links) there are the same dongles with 802.11 b/g/n 150Mbps

For 10$ with Ralink RT5370 chip: VID=148F, PID=5370. http://www.ralinktech.com/en/04_support/support.php?sn=500 (Windows, Linux and MacOS)

But I don´t know... I would use my alfa AWUS036H rtl8187L I´m addicted :/

It would be great when the boards come out if people could post here which wifi dongles they've found work with R-pi to save us having to hunt for chipset support on our favourite retailers sites.

Ok, since we're on the subject, maybe you guys can help point me in the right direction....

I recently stripped a Lexmark multifunction inkjet that had a wifi module as well. I pulled the module and it was just hooked up to a mini USB jack inside. I was hoping to use that module as a Wifi adaptor for the RPi, but I haven't been able to find out much of anything about the module, and I'm no Linux guru...

I believe (sorry, don't have it with me here at work) it the numbers on the module were Lexmark X2100 (I'll check when I get back home tonight.) No indication of chipset though.

Thoughts?

It may be better that the dongles found to work are posted to the wiki rather than the forum.

Forum for discussion, wiki for verified information seems like a good idea.

connect it to a linux box and see if it finds it.

If you dont have one set up use a knoppix live boot disk to boot any PC.

Wi-fi? Surely it should be Pi-fi, or Why-Pi!

I have another wired-only device in my living room, so I opted for a wifi access point/4-port switch, running in AP client mode. This seems to be working just fine, and might be a better option for anyone running several RPis.

I don't think I have tested any of those devices - it's someone trying to cash in I think.

I think this could work.

Thanks for the link to compatible Wi-Fi adapters/dongles!

Question...

I have an iPhone, and I want to use the HippoRemote app with the RPi for a virtual keyboard/mouse. HippoRemote does work on Linux, and should work as-is through screen sharing with one of compatible Wi-Fi usb adapters. My question is, in the absence of a router, can I configure the RPi to set up it's own network and connect with it through HippoRemote?

For a TESTED list of USB Wifi adapters, please see the Wiki - the ones on that linked page haven't been tested on an actual Raspi (but they might work).

Thanks, I certainly will. Any idea if I can do what I asked with a compatible Wi-Fi adapter?
