Good afternoon. First post here as I'm a complete gentoo noob.

I downloaded the Gentoo live environment iso and created a bootable USB (using dd), but my wireless "doesn't work". By "doesn't work" I mean it's not being detected at all -- it doesn't seem to know it exists (yes I tried net-setup). I have a Dell XPS 13 Ultrabook (about a year old - set to legacy BIOS boot not EFI), but replaced the Intel advanced card (non-free) with the Atheros AR9285 since the drivers are free software and the support for the card are in the mainline kernel. It works *far* more reliably than the Intel card on different distros (gentoo is the first it didn't work OTB), so I was surprised when it didn't work or even register at all.

I did some searching and found that the kernel module responsible for the card is ath9k -- so I issued 'modprobe ath9k' and got an error message "fatal" that the modprobe had failed because the module doesn't exist. I have installed Arch linux with luks+LVM so I feel like I'm capable of installing Gentoo properly with systemd for Gnome since it's my DE de choise.

My question is this:

Can I use *any* live USB to install gentoo? From my understanding, the first part of the install is completely distro-independent. If yes, what is your preferred distro to use to install gentoo on a modern PC (read: good wireless support, modern kernel (3.10+))?

Thanks in advance!

For the first part:

Yes, you can use any live-dvd/usb to install gentoo.
I usually use the Gentoo live dvd or usb.

However, Usually on a fresh install on a machine (laptop) I try to use a wired connection to avoid any wireless issues, and I install wireless later on...
Is there any reason that you need to do this wireless ? ( since usually, wifi support on live systems might sometimes be hard due to all kinds of laptops/chipsets in my experience).

Alex.

Yes, you can. I use a LiveCD of SystemRescueCd, which is based on Gentoo and has all the tools you need to make installation easy, including a DE (Xfce) with GUI Web browser (Midori) so that you can follow easily the Gentoo Handbook as you install Gentoo on your HDD.

If wired (from the previous suggestion) isn't an option, you can look at SystemRescueCd which contains quite some wireless modules and tools; a lot of people that can't get it to work using the typical installation medium, SystemRescueCd works for them.

Seems Fitzcarraldo posted the same suggestion a few seconds earlier, you can see this post as an extra vote for that then...

No, you can't use any liveCD/USB.
There is one limitation: the live system should be the same architecture that you planning to install. For example, if you planning to install x86_64 Gentoo, you have to boot with x86_64 live system. Otherwise you can't chroot into your installation environment.

For which reason?

Why is this a limitation?

Awesome. Thanks for the recommendation -- I'll give SystemRescueCD a shot. Unfortuantely, this laptop *only* has wifi... no ethernet, so I *must* use wifi for the initial setup. That's one of the reasons I changed wifi cards -- loading the iwlwifi firmware for my card was a PAIN in strictly free live media, and it was entirely unnecessary imo.

I appreciate the help and I'll do my best to contribute here if I can :)

I would also make sure to use a 64-bit media since it's unpredictable if there could / would be issues with that... I always just try to be conservative so thanks for the heads-up.

Thanks!
