USB wifi dongle and retropie

IanDaemon

What model Pi are you using? Wifi may be built-in thus not needing a dongle.

Why the double topics?

Donkbot

oops, my mistake, didn't see topic appear so reposted. Can remove now

I have a raspebery 2 i think, thats whats written on the board

Does this help?

IanDaemon

Sounds like you could use dmesg | more to check things out, but then you still have to configure the dongle.

Donkbot

Thanks, I'll have a go, presumeably there is a way of accessing the linux CLI from retropie

IanDaemon

The terminal? Just press F4 or "quit 'emulation station'" if you're using that. Where are you?

Exit to command line/terminal.

Although the vendor page says there's no Linux support, it looks like it's using the RTL 8821CU chipset, so it might work by installing the driver from https://github.com/brektrou/rtl8821CU.

I exited emustation and dropped into a CLI. entered "dmesg | more " and it returned Command not found

I'm in the UK

@mitu

Really? just checked the amazon page where I bought it and your right, that'll teach me not to read the specs carefully

So im assuming a supported dongle would be pretty much plug & play?

You need to leave spaces around the pipe character (|).

If it's supported by the Linux kernel, then yes.

Thought I has done that, anyway working now.

Looks like the device is being recognised, I can see:

usb 1-1.2: new high-speed USB device number 6 using dwc_otg
usb 1-1.2: New USB device found, idVendor-Obda, idProduct=c811, bcdDevice= 2.00
usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-1.2: Product: 802.11ac NIC
usb 1-1.2: Manufacturer: Realtek
usb 1-1.2: SerialNumber: 123456

Do I still need to install I a driver I wonder? That guide seems to go straight onto configuring the wifi (which I thought could be done through retropie-config)

Donkbot

Also, that driver on githib doesn't appear to have any releases. Am I going to have to build the project first?

There are installation instructions (using dkms) on the project page - there's no need for a 'release'.
