I have just installed Chromium OS on an old 32bit Samsung N130 netbook. I used the latest 32bit image (60.0.3112.102) from Arnold the Bat.
Using the lscpi command , I found that it has the Realtek RTL8192E/RTL8192SE Wifi NIC which is listed as supported in the release notes.
When I try to switch the wifi on using the normal settings it just doesn't go on.
Having looked into this, I found that this chipset had given problems for people with this laptop before in other Linux distributions. I have encountered similar problems in the past trying to get Broadcom WiFi to work when installing Ubuntu or Debian on older Apple hardware and it could be fixed by installing an application to extract the firmware and install it e.g fwcutter
I know that Chromium OS is Gentoo-based and I do not know the best way to proceed to check if the right driver is installed and to make sure that the wifi can be activated. I have read that Gentoo is for more advanced users and I miss apt-get!
When I next get the chance, I will try installing Ubuntu, saving the /lib/firmware folder and then reinstall Chromium and merge the firmware folder with the Ubuntu one. It might work...
