 |
|
OK, so after a few months of unprotected wifi, seing others come into range lately and some horror stories my boss told me at work i finally bothered my ass to secure my wirless router (A BT Voyager). I have a centrino laptop and have setup the following
in /etc/conf.d/net
| Code: |
modules=( "wpa_supplicant" )
wpa_supplicant_eth1="-Dipw"
wpa_timeout_ath0=60
iface_eth1="dhcp"
|
and in /etc/wpa_supplicant.conf
| Code: | ctrl_interface=/var/run/wpa_supplicant
network={
ssid="MYNetwork"
scan_ssid=1
proto=WPA
key_mgmt=WPA-PSK
psk=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
} |
i have the folling in my kernel autoload
| Code: | ipw2200
ieee80211_crypt_tkip
ieee80211_crypt_ccmp |
I have been reading various documentation but it most of what i find almost seems to assume you know what the hell you are doing. Maybe its just because its friday and my brain has been scrambled by my weekly exposure to Microsoft Products and AutoCAD Electricals Evil data backend but I am just not getting this at all.
My router is set to WPA-PSK with TKIP encryption only (has the option of AES or both). Anyone got the same setup care to share?

same here, i have been tinkering a bit with my ipw2200 and it really appears that you need a phd in cs to get it up and running..
No help from my part, sorry  |

It seems that the ipw2200 is becoming famous for being tricky to manage for all but the most experienced. I have been wrestling with mine on various distros for about a year now and can always get it to work eventually but never 100% especially with respect to automatic association with multiple APs.
I have been using iwconfig/wireless tools just lately and finally given up troubleshooting it with this approach so I will be trying wpa_supplicant this weekend myself. Just gotta work out how to do the switch without causing more trouble than I already have. I can always associate with my APs but it has to be by manually setting the /etc/conf.d/wireless file to specify the essid for one of my networks and leave it to auto associate for the other! I have tried all combinations I can think of and exhausted help at LinuxQs and here so I am going to follow the wpa_supp approach which will involve me losing my connection no doubt 
Are you both getting the firmware failures in messages? This is apparently fixed by handing the card some kind of hardware crypto initialisation string which I think you can only do with wpa_supplicant - anyway perhaps we can figure this card out and get our own phds

and yet despite all this my wifi networking is really working - just the auto association that I can detect as a problem - so go figure eh?

Which kernel and version of ipw do you use?
Try -Dwext as driver and set timeout to use eth1 instead of ath0

...ok - sounds good - was that (to me?) before moving to wpa_supp or after?
this is a hand rolled 2.6.15 so:

Don't bother reading through all of this - it's just a taste of what I have going on despite the fact that I am typing this via my ipw2200!!

Add hwcrypto=0 to the options line in /etc/modules.d/ipw2200
Hardware crypto is broken. That's what causes those firmware errors. |

I have heard about the hwcrypto flag fixing firmware errors but havn't been able to work out how to use it with the in kernel ipw2200 driver and wireless-tools/iwconfig setup.
I don't have any ipw2200 module...
| Code: |
geko modules.d # ls -al
total 24
drwxr-xr-x 2 root root 4096 Mar 2 19:38 .
drwxr-xr-x 59 root root 4096 Mar 5 08:22 ..

It looks like I will have to switch to wpa-supplicant to be able to use the genuine ipw2200 module and pass it this option...
Do I need to do anything complicated to switch from wireless tools to wpa-supp???
(I am very sorry Ninja and ctrl-alt-del to have hijacked this thread - I will ensure I report all my results here for the original posters to benefit)
we really need to get this wireless card sorted for the inexperienced - although I have learned everything I know about wireless because it didn't "just work" so...  mixed blessing me thinks.

I have switched to wpa_supplicant and added the hwcrypto=0 flag.
The configuration and subsequent association happened without any drama to my work network. I will monitor these firmware errors and see if they abate.
edit: association with my home network is fine and there is no more sign of the firmware errors - so this looks like a great solution...
seeing this though now:
| Code: |

Not sure why this is happening or who is responsible.
