Bug Description
I used the Alternate Text Based Ubuntu 32bit 7.10 setup CD ROM.
I applied all the latest updates to 21 March 2008.
I chose English as the language, the first question asked during setup. The second question was:
Ubuntu suggested some English-language dominant countries; I picked Other then selected Germany.
Ubuntu SHOULD have added 'options mac80211 ieee80211_
It didn't. I could see with the top-right network icon (nm-applet 0.6.5) all nearby radios, but not connect to, an Open AP on channel 13.
This is a BUG.
Extended Background:
With a built-in MiniPCI radio, a PrismGT Fullmac 54mb/s ISL3880/90 card, the laptop (Sager/Clevo D500P) under Ubuntu could -see- all networks Ch1-13, but could only -connect- to those using channels 1 through 11. In Europe, the channel standards are officially 1,5,9,13; however, since as US so the rest of the world (esp Western Europe), sometimes for bad... 1,6,11 are very commonly used. Sometimes people have bought laptops -in Europe- from major manufacturers (Toshiba) assembled with incorrect radios sku'd for channels 1-11; the Intel 2200BG for example, and -cannot operate- on Channel 12,13 unless the firmware is modded (with linux :).
A open (public-access) AP WLAN operates near the laptop, on channel 13, placing radio signals farther outside of typical interference and traffic zones. In XP, (using the SMC 2802W drivers or others) I could not see the Ch13 AP at all, although many more distant radios (on 1-11) were visible. On Ubuntu 8.04 Hardy Heron, I could see Ch13 AP, however nm-applet (the applet on the top-right for networking) always got stuck attempting to connect (the spin of infinity / death) (21 March 2008).
I joined channel #prism54 on irc.freenode.net. Several pages of conversation took place while users 'linmax' and 'roadi' helped out. While I had 8.04 loaded and problems with the completely broken wireless/wired nm-applet. 'linmax' then tested several of his own fullmac radios on channels 13 and had no difficulties. I erased 8.04 and loaded 7.10. 'linmax' suggested putting 'options mac80211 ieee80211_
Prism54 is blacklisted in 8.04. However, prism54 was loaded simultaneously with p54pci and p54common in 7.10 (lsmod output). Prism54 was manually blacklisted in 7.10 as one of the first post-setup 7.10 configuration steps.
