I'm having layer-2 problems with the wireless.
(I will have to go plugin at the terminal room to send this)
I tried most of Sunday to get online, but I never succeeded. It is
no better this morning. I am guessing on the noc email, I will send
this again once I get web to find out what the noc email is.
I am sending this in the hope that
It looks like there are just too many APs.
I am using an external orinoco 802.11b card "Lucent Technologies GOLD",
but I have similar experiences with cisco Aironet cards. (Yes, this is a
card from an ietf 40-something meeting). The driver/orinoco-firmware
combination does not let me get a list of APs (too old), while the cisco
one does, but the cisco one never sees any AP, even though it can get a
list of them.
I've never had problems with wireless, and I'm pretty kernel competent,
and the same cards were last used 2008-03-06. I'm running debian
"GNU/Linux" etch with a custom 2.6.20.6 kernel. I suspect that my cards
might need firmware upgrades to deal with some new-fangled mechanism, but I am
ignorant of what that might be.
(I am in the market for an external 802.11a card that has a sufficiently
enlightened policy about releasing details such that quality open source
drivers can be written. No binary blobs please. The last one I ran
overheated the internal radio, and destroyed my motherboard)
Sitting at one end of the breakfast area I get:
