 |
|
Hi!
I'm in desperat need of an advice here. 
During boot my wireless tries to connect to my AP, but it fails, the error is something like:
| Code: | | Failed to connect to any wireless access points |
But after login it's enough to run dhcpcd ath0, and I'm all set, up and running. This is how my /conf.d/net looks like:
| Code: | modules=("iwconfig")
channel_ath0="11"
key_myESSID="[1] my_hex_key [1] enc open"
preferredonly=("myESSID")
#preferred_aps=("myESSID")
blacklist_aps=("NeighboursESSID1" "NeighboursESSID2")
config_ath0=("dhcp") |
and when I, after login runs: iwconfig
| Code: |
ath0 IEEE 802.11g ESSID:"myESSID"
Mode:Managed Frequency:2.462 GHz Access Point: 00:0F:B5:22:D0:88
Bit Rate:11 Mb/s Tx-Power:18 dBm Sensitivity=0/3
Retry:off RTS thr:off Fragment thr:off
Encryption key:my_hex_key Security mode:open
Power Management:off
Link Quality=28/94 Signal level=-67 dBm Noise level=-95 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
|
The thing is my wireless gets associated correctly, but it doesn't get the dhcp request completed, it seems to me.
Anyone who can tip me on this_
thanks

Are you using WPA or WEP?

trying doing this since your using WEP...create a script.
#!/bin/bash
modprobe (your module here, if you are using ndiswrapper, put ndiswrapper here)
iwconfig ath0 mode Managed
iwconfig ath0 key open (your key here)
iwconfig ath0 essid (your essid here)
dhcpcd ath0
save that file.
do a chmod +x (your file name here)
then at the command prompt type: ./(your file name)
Try that.

Yes, I know, I ran that script before, but I think I am so close, it ought to work the plain and simple way. I just don't understand why it doesn't work. Works fine on a DELL laptop (Intel PRO Wireless 3945), but not with madwifi (not the same card, or machine).
I've used the script, but this time around I was hoping to do without...

Hi martinm
Just checked, I'm using v. 2.0.5
dhcp works, just not during boot configuring my wireless nic, dhcp works for my wired nic. After login it's enough to do dhcpcd ath0, and I got an IP.
Aaaaarrghhh! This pisses me off. Maybe I just have to bite the dust. Can't get it all, it seems.

There's another thread here which might be helpful.
It has a post which points to a third thread...

Yes, that patch would be something... but the link to bugzilla turns out bad (dead or moved).

The URI has a typo, it should be https://bugs.gentoo.org/show_bug.cgi?id=143698, it had a "." added on after the final 8

Yes, wynn, that patch looks just right for me, I really think that one would be quite usefull. Yes, I can definetly see that patch as something very, very interesting, and actually the thing that we have been looking for.
Dare I be that bold, mr wynn, to come out straight forward and plea for some advice on how to use that patch, in a certain newbie kind of way?
Anyhow, thanks for pointing me the direction thus far...

I'll have another look at the patch â I seem to remember that there was more than one.
Unfortunately that "look" will have to wait, there is a database error message on bugs.gentoo.org at the moment.

Great!
Thanks, mate
This is my "last" problem, part from this Gentoo now runs just perfect, at least as far as I can tell.

If you were thinking of the "if_down_up_hack.patch" then all you have to do is to open /lib/rcscripts/net/iwconfig.sh in nano, search (^W) for "scanning" and you will be at this point | Code: | done < <(iwlist "${iface}" scan 2>/dev/null)
if ${error}; then
ewarn "${iface} does not support scanning" |
To add the patch, go to the blank line before "if ${error};" and add | Code: | # HUP the interface as some drivers/cards need it
interface_down ${iface}
interface_up ${iface} |
Is that what you wanted?

I'm glad you've got it working.
Time to change to wpa_supplicant now, isn't it?

And also causes major grief with other wireless drivers, so that madwifi only "fix" was removed.
But as I think about it, it may also have been caused by a long standing issue with dhcpcd. Basically versions 1 and 2 only sent 1 discover packet by default. So if it got lost over the wireless then tought.
With dhcpcd-3 we have a better approach were we re-send the request if we don't receive a valid DHCP packet every 3 seconds.
However, that had a new bug where we stopped listening after the first re-send - lol.
Anyway, I think all dhcpcd issues are now solved, so why not try out this tarball with the up/down hack removed.

Thanks for testing and getting back to me
