Small WiFi adaptor

Sat Aug 11, 2012 12:40 pm

Does Raspberry Pi support a small WiFi adaptor, such as the one linked below?

Yes, it uses the RTL8188CU driver.

It mentions on the verified Peripherals page that this particular one needs to be plugged into a powered hub to work properly. Which is a shame because it's about the smallest wifi adaptor on the planet & it'd be nice to just plug it in and forget about it.

Does anyone know if that's still the case?

If you want a small dongle without having to use a powered USB hub, just get the Edimax EW7811Un or one of its clones and run MrEngman's installation script. Many people on this forum have reported using this device without a powered hub. I am using a clone of this device (AirLink101 AWLL5088) with a 1000 ma power supply and I have never had a power problem when connected to either of my two routers. It has the same chipset as the device listed by the OP (RTL8188CUS), so I am surprised that a user reports that it requires a powered usb hub; Possibly the manufacturer's implementation of this clone device requires more power, or something is different with the pi it was tested on (Poor power supply, high resistance cables, other high power drain devices, extremely high network traffic, audio related problem as reported by the user, etc.).

I would recommend the one i got, a ZyXEL one. Read all about it at http://blog.fagerbakke.net/2012/7/10/ra ... less!.aspx

I managed to get a wifi dongle working directly from the 2 USB slots on the RasPi.
With a dual USB cable I already got from a broken hard drive enclosure I had and one female/female adapter. Using the two slots are effectively pushing 300mA to the dongle. (!!!)

I found a cable for sale, no need for F/F adapter: http://www.shopaddonics.com/itemdesc.asp?ic=AA2USBPC

I got a tiny one off ebay for a few quid that works fine. It was recognised in the Pi but by the time I got round to setting it up I had a powered hub. It's rock solid in there, but I'll try it direct in the Pi tonight.

Just have to say that I connect to my raspi with VNC, so no need to have a keyboard and mouse... I know I'm using the 2 USB slots... The thing is that my raspi is powered from a lipo battery and solar charger. With a little sun and wifi signal, it is a completely power autonomous computer and it works 24/7.

Also running mrengman's compiled module 8192cu here for my Trendnet TEW-648UBM

Code: Select all

Bus 001 Device 004: ID 20f4:648b TRENDnet TEW-648UBM 802.11n 150Mbps Micro Wireless N Adapter [Realtek RTL8188CUS]

The built in kernel module "rtl8192cu" that shipped with raspbian seriously just hanged my machine and spammed dmesg with modprobe timeout failures. I blacklisted it as

Code: Select all

$ cat /etc/modprobe.d/rtl-blacklist.conf 
blacklist rtl8192cu
And after that added the 8192cu from 8192cu-20120726.tar.gz to /lib/modules/3.1.9+/kernel/drivers/net/wireless/
Then it started to load fine, and wpa_supplicant had no issues hooking me up on my 802.11n wifi

As for the card itself ... yes it's tiny, yes i just run it off the built in usb port of the raspberry, seems to work just fine from there.

I just bought the AusPi Technologies Raspberry Pi Wireless adapter. It works straight out of the box, without a powered HUB using the RTL8188S drivers.
I got it for the 2dBi antenna, so it's got better range than those micro USB ones.
