I'm having problems installing Gentoo (who would have thought, right :) ). I've been googling for the last day for a solution but to no avail.

I'm trying to install Gentoo using a USB wireless receiver for the internet side, but it isn't working properly. I was hoping some of the people here may be able to shed some light on it for me.

Some info:
Receiver: TP-Link WN821N
Driver: Atheros 9000 (ath9k)

Through dmesg, I've figured out that the device is at least detected:

Quote:

usb 1-1.4: New USB device found, idVendor=0cf3, idProduct=7015
usb 1-1.4: New USB device strings: Mfr=16, Product=32, SerialNumber=48
usb 1-1.4: Product: USB WLAN
usb 1-1.4: Manufacturer: ATHEROS
usb 1-1.4: SerialNumber: 12345


Here is some output from various programs:
dmesg: http://pastebin.com/gQr7k75w
lsmod: http://pastebin.com/w9QypKwE
ifconfig: http://pastebin.com/53DMd9Z4
iwconfig: http://pastebin.com/f823DV7g

I'm fairly certain this last one is redundant for my purposes as it's for PCI devices, but I saw it in one forum post so there's no harm in posting it;
lspci: http://pastebin.com/WbaWRnSp

The drivers are loaded (they came on the LiveCD), I made sure (modprobe ath9k) as well. I'm fairly certain I'm just missing something important, I hope my question isn't too dumb for you guys :)

Thanks for your time
- Dylan

I must thank you for providing lots of info. A lot of people just say "doesn't work" and then one must pull info out of them, which is tedious. But, dmesg output is not very hard to read. A quick search for ath9k, and you'd find this line:
Code:
usb 1-1.4: ath9k_htc: Failed to get firmware htc_7010.fw

That's the problem. Basically, the gentoo install cd doesn't contain any firmware. So if your device requires one (most wireless devices do), and you don't have a wired connection, the gentoo install cd is useless. Use something else to install gentoo, SystemRescueCD is usually recommended.

PS. The driver is not actually ath9k, that one is for pci devices. The usb driver is ath9k_htc.

Thank you for helping :)

I thought that wasn't the problem, I saw a forum post which said:

Quote:

If your driver is built in, the firmware must be built into the kernel too.
If your driver is a module, the firmware goes in /lib/modules

(from http://forums.gentoo.org/viewtopic-p-7205722.html)

I can make it to a wired connection, I'd just prefer to do it with a USB receiver because it saves me transporting my computer to the other side of the house, plus a challenge is always good. I guess it wasn't to be.

Again, thanks for taking the time to help me, may many Gentoo's be with you.

- Dylan.
