Summary: driver picks first AP in scan list

Initial Comment:
I have a minor but serious problem...
My second neighbour also have a wireless network
and I&#039;m still in range...
The problem is: the driver seems to start a AP scan,
and find HIS first!
Since reinit isn&#039;t working, the card sync to HIS AP and
won&#039;t let me to switch to mine...

My solution is: put a few cds to block the signal of my
friend AP so it pick mine instead...

Here is all the bugs I got
- 0.2.0pre7 and CVS dosen&#039;t work on 2.4.25 (unresolved
symbols), non-pre worked fine, but worked fine on 2.6.4
- eject the card ooups the kernel
- can&#039;t change anything: once initialised don&#039;t touch
or bye bye connection
- slower than in xp (under 50% of xp speed)

ok, problem is back
and I have dmesg logs :/

I'll paste here the most important part and attach the
complete output

======== wrong AP ========
acx100_process_probe_response: found and registered station
0: ESSID "default" on channel 6, BSSID 00 80 C8 23 61 BD,
Access Point/22Mbps, Caps 0x0041, SIR 29,
SNR 0.
Radio scan found 1 stations in this area.
<Scan Table> 0: SSID="default",CH=6,SIR=29,SNR=0
peer_cap 0x41, needed_cap 0x01
ESSID doesn't match: "default" (station), "4565" (config)

now I block the signal with cds

======== good ap, less than 4 feet away ========
acx100_process_probe_response: found and registered station
0: ESSID "4565" on channel 6, BSSID 00 40 05 55 19 93,
Access Point/22Mbps, Caps 0x0041, SIR 90, SNR 0.
Radio scan found 1 stations in this area.

also, I get...
Tx error occurred (error 0x20)!! (maybe distance too high? -
change 'iwconfig txpower XXX')

iwconfig call is:
iwconfig wlan0 essid 4565 channel 6 mode managed

aw, what a bad report I did... that's what happend when you
write things at 6am (before you go to sleep, not when you
wake up)
anyway

My setup:
- DLink DI-614+ (wireless router, 802.11b+, 22mbps)
   - channel 1/6/11 (currently 11, all do the same thing)
   - essid changed to "4565"
   - WAP disabled (couln't make it work under linux)
- DLink DWL-650+
   - Running under Gentoo
   - kernel 2.6.4 / 2.4.25

other AP should be a SMC something (I have no confirmation
yet that it's his, but I beleive so..)
on channel 6 with ESSID: default

what seems to happend is: the card do a scan, find his AP,
then connect to his, then the driver try to change the
parameters... and that's where the problem begin...

then it lost the signal

I'll try to reproduce it and I'll post the dmesg result
right now I seems to be unable to get my friend's AP signal
(disabled my AP, don't get any signal now... that's what
happend when you are on the border line...)

yes, xp use 4X, if I get time and if I'm bored then I'll
reput XP on my lappy
(6 gig isn't enought for 2 os) and I'll do benchmarking
(idea on how to do it the best is always welcome, as I
beleive copying files isn't the best way, but should be good
enought)

another post is comming asap with better log...

Please provide a more detailed description.
I don't have any setup information from you, I don't have
any information about his AP, and no logs provided. My
crystal ball is broken today ;-)

I'd actually go as far as saying that if you had done a
proper log analysis you'd have known why it picked his and
not yours...
(such as having specified the wrong ESSID or so...)

Is that really pre7 or a plus_fixes version of it?
And what does non-pre mean? We've been using pre quite long
now...
- card eject may still oops the kernel in case of running
traffic (proper hardware management is difficult)
- I have to do more tests about that one - we probably
sometimes don't act the way we're supposed to on parameter
change...
- hmm, is that with 4X mode enabled in XP or not?
  if it's much slower with 22Mbps or 11Mbps STANDARD mode in
Linux than in XP, then I should try to debug it
I don't have any reference numbers here unfortunately, since
I NEVER EVER use XP...

Sorry for these problems, it's almost a one man show
currently, and a wireless driver is not exactly child's play :-

I forgot, I was unable to set an encription key, lost the
connection
(it then say something like out of range, can't find AP....)
