Advent 4213 - No wifi

Description of problem:
No wifi is detected in Fedora 10 on the advent 4213 notebook.
Version-Release number of selected component (if applicable):
Latest from the repos.
[root@smallfry ~]# rpm -qa | grep kernel
[root@smallfry ~]# rpm -qa | grep Network
Steps to Reproduce:
1. Get a 4213
2. Install fc10
3. Update via yum
No wifi is picked up by NetworkManager
That wifi stations are shown in NetworkManager
Can you do the following, all as root?
service NetworkManager stop
killall -TERM wpa_supplicant
iwlist wlan0 scan
Does the last command show any output?
[luke@smallfry ~]$ sudo su -
[root@smallfry ~]# service NetworkManager stop
Stopping NetworkManager daemon: [ OK ]
[root@smallfry ~]# killall -TERM wpa_supplicant
[root@smallfry ~]# iwlist wlan0 scan
wlan0 Interface doesn't support scanning.
Ok, with NetworkManager and the supplicant *still* stopped, try (as root):
ifconfig wlan0 up
iwlist wlan0 scan
I forgot that for most devices, they need to be "up" first.
wlan0: unknown interface: No such device
What wifi devices does "iwconfig" report?
Doesn't pick any up;
lo no wireless extensions.
eth0 no wireless extensions.
pan0 no wireless extensions.
Ah, ok, misunderstood. The problem is that there is (as yet) no kernel driver for your hardware, which is a Realtek 8187SE 802.11b/g part.
Is there any plans to enable any of the wireless drivers in the staging part of the kernel tree? This would enable testing of both these drivers and the other fun driver in a lot of netbooks - the Ralink RT2860
No. These drivers are not of suitable quality, and kernel wireless people object to their inclusion in staging in the first place, since (at least in the case of ralink) the driver will *never* be officially accepted until it's completely rewritten anyway, since it doesn't use the kernel's standard 802.11 stack. Other staging drivers like at76_usb *do* use the standard 802.11 stack, so they are much more likely to be enabled.
Staging drivers are not of acceptable quality to be included in the mainstream Linux kernel, and thus we shouldn't be turning them on in Fedora at a whim either. Any panics or problems with staging or otherwise out-of-kernel drivers like ndiswrapper, nvidia, ati, etc are likely to be ignored, because they have not passed the kernel's quality acceptance bar and are not mainstream.
