My only consolation is that this fault is not intermittent. :-( |

|

Here's what happened. I emerged a different (to my tried & tested rt2x00-9999 |
4 |
wireless driver). Then I uninstalled rt2x00-9999, but I couldn't get the new |
5 |
driver to work. So, I unmerged it, remerged rt2x00-9999 (this is a CVS |
6 |
package) and I have not been able to make it work ever since. I even |
7 |
recompiled the kernel in hope of getting it to work, but I can't get it to |
8 |
detect any Access Points: |

Would you perhaps know how I may be able to troubleshoot this thing before I |
75 |
lose my temper and throw it out of the window? |
76 |
|
77 |
PS. I might have un/plugged it during probing/scanning - could that have |
78 |
caused some physical damage? |
