 |
|
Hello gentoo community, I have an issue. My old hard drive decided to die on me so I had to reinstall gentoo on another hard drive. For some reason I cannot get wifi working on my new install I think I must be missing something in the kernel config but I don't know what it could be. I followed the gentoo wiki to install wifi here is my info.

<3 ... to use iwconfig (net-wireless/wireless-tools), and wicd, you need to have CONFIG_CFG80211_WEXT=y. Both use the old wireless extentions (WEXT), and it looks like the compatibility layer (CFG80211_WEXT) isn't enabled.
| Code: | | # zgrep WEXT /proc/config.gz |

Does the Intel Corporation Centrino Wireless-N 1000 really need WEXT? |

charles ... its not the iwlwifi driver, its CFG80211. CFG80211_WEXT is a compatibility layer ... so that tools still using the (now depreciated) WEXT (like wireless-tools, wcid, etc) can still function. If you use net-wireless/iw and have nothing that explictly expects to use wireless-tools (ie, x11-misc/i3status, app-admin/conky ... and probably others), then there is no need to enable CFG80211_WEXT.
