Installing Gentoo with minimal cd issue

[lazykoala]

In this thread:

I successfully make wireless network work then I finished the installation of gentoo according to handbook's steps. (use genkernel all to configure kernel)

However, after I login to the new system. The wireless network module doesn't automatically load, worse is the module doesn't exist in /lib/modules/.../net/wireless folder, and lots of commands(which can be used in live cd) are not available: net-setup, wpa_passphrase and etc.

Anyone can help? Thanks.

I'm not too familiar with the genkernel setup, but the lack of commands I think is attributable to the fact that the live CD has a lot of general purpose programs, while the stage3 is much more bare, so you'd probably need to install those programs yourself. If you're in a position where you could plug in a network cable, you could do it that way, or you could chroot in and install them at that point.

You're going to need to follow the Gentoo Network Configuration portion of the Handbook. There's a section dedicated to wireless. Once you look at that, if you have any questions, just ask.

Thank you very much. I've read the network document. As I said in the other thread I mentioned above, my problem is NOT how to configure network, it is after installed the base system using stage3-tarball, my wireless adapter card can't be identified. I don't know how the live cd makes it work. I hope at least the new system can work like the minimal live cd, automatically identify the wireless adapter card.

Okay, although the network guide explains it, let me walk you through it. Could you post the output of

Thank you very much. The command lspci & lsusb are not avaible in my new system, and lots of other commands.

Now I'm using systemRescueCd to install gentoo again. It's a fantastic tool. I boot from GUI. The following is my system information:

The existing wireless usb adapter is very unstable. I bought a new one: TP-Link TL-WN721N

If the module for your network device does not exist this can be due to 2 things:
1) You (or genkernel) didn't specify it when you configured your kernel.
2) It is not compiled as a module but built into the kernel

If it is 1), you need to go to /usr/src/linux, make menuconfig, and look for your network device in Device Drivers → Network Devices → Wireless
If it is 2), you should find it marked with [*] and the driver will be built into the kernel. With 3.12.13 I had the problem with my Intel card that it would not load the firmware if it was built in, so I had to compile it as a module.

For your new TP-Link device you seem to need the ath9k_htc driver, according to this here: http://wireless.kernel.org/en/users/Devices/USB

Thank you very much Clad, it's very helpful. I'm now reinstalling my gentoo using new usb wireless network card.
And especially thank you for explaining the reasons why my system is not working.

You should not reinstall it, your first install was OK, you just had to add some packages. You do not need to reinstall for that.
