Knetwork manager no WLAN, ifup working fine

English Network/Internet
#1

I am new to this specific forum - so Hello to everyone.

I have searched around a bit for a knetwork manager issue I am having on my opensuse 11.2 32 bit install. My wireless card is an

04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)

I am currently using the Broadcom wl driver

I am on the Internet with this machine as I am typing using the older “ifup” method. I am having great difficulty connecting to the Internet when I use knetwork manger though. The strange part is when I am connected to my router with knetwork manager, I can log into my Router, but I can not get to any web-page/ping any outside address.

so far the best (I was able to locate) advice I was able to get is located in this post. < Broadcom wireless, partchy internet - openSUSE Forums >

following a posted how to to disable IPV6 (I suspect this may be the issue??), I was unable to locate modprobe.conf, or modprobe.conf.local, even after I updated via updatdb. I gave a shot at entering in “disable_ipv6=1” into “menu.lst”. However, this did not solve my issue with knetwork manager.

any suggestions? If my network information is needed when I am “connected” utilizing knetwork manager, please let me know. Hoping there is something simple that I may have overlooked. . . Any experienced sugestions?

Please post the result of the following in a terminal

uname -a

rpm --query --all '*broadcom*'

su -

hwinfo --wlan

Sorry. Did not have the option to edit my above post. I have found the article to disable ipv6 at < CND0230W | collectNWData.sh Fehlermeldungen >

Folling the intrructions, rebooting and re-running the supplied script, ipv6 is still enabled. Wow, what a pain in the behind. Any other suggestions besides… What I am not sure how to do is "Insert the option ipv6.disable=1 during boot. ". I already added this line into Grub2. i have to assume this is not enough.

Problem fix
Attention: For OpenSuSE 11.2 see below.

Disable IPV6 mode in the OS:

Create /etc/modprobe.d/ipv6 and insert

install ipv6 /bin/true

Disable IPV6 mode in FireFox:

Invoke Firefox and insert about:config. Then insert following definition

network.dns.disableIPv6 boolean true

or just change false into true

For OpenSuSE 11.2:
Insert the option ipv6.disable=1 during boot. Then change /boot/grub/menu.lst to use the previous parameter in it’s boot option.

Wow, fast reply. thank you

I have found the ipv6 is still enabled, hmmph…

the following is still using “ifup”. I will update this post after I shut down this connection with the results from network manager.

Have you added the ipv6.disable to menu.lst? or Not?
You mention grub2, but SUSE uses grub legacy.

wlan seems active though.

su terminal

cat /boot/grub/menu.lst
#7

Yes it is in the Grub File. I may have mixed up Grub and Grub2 when typing. I have been Distro hopping a bit lately.

Heck, I never had this much issue with Knetwork manager even in opensuse 10.2.

I am beginning to wonder if I need to Recompile the kernel since I can not turn ipv6 off no matter what I do. I can not get to my Grub list right now since I am at work.

Acutually modifying menu.lst brought up another agravating point I am finding with 11.2. Kate or Kwrite will not run in “su” which is completely weird in 11.2. I had to use pico to Edit menu.lst since Kate and Kwrite will only run as my user ~ weird

#8

In a normal user terminal, then enter password when requested.

kdesu kwrite /boot/grub/menu.lst
#9

sicne opensuse 10.0, if I entered in su, then the root password I was able to use kate. for some reason why kate and kwrite keep crashing in 11.2.

I do appreciate your help. I am stating to believe this will probably not get corrected in opensuse 11.2

#10 
axel@VBox-112-64:~> su -
Passwort:
VBox-112-64:~ # kwrite

Works for me™.

And BTW:

Why do you want to disable ipv6, if your Network “works fine” with ifup?

Makes no sense at all.

#11

Honestly, My “Guess” is to disable IPV6 to get Knetwork manager working properly. So you proposed a good question!!

I can connect to my Router, But I can’t get to the Web [when using Network manager]. So this is really puzling me.

I found this person has the identicle issue, unfortuneatly no solution here either < knetworkmanager 4.4.1 does not connect properly • KDE Community Forums >

Hmm, I remember when Running Fedora a few Years back I had to use “su -” instead of just “su”. I guess this may have changed. Thanks for the suggestion, I am now itching to try it when I get home. Thank you I bet that’s it for my Kate/Kwrite issue :). Now for Network Manager, LOL

What is to correct? or a number of reasons, ipv6 is not built into the kernel,
not as a module. As a result, disabling it with YaST is not sufficient the way
it was in 11.1. Thus you need to add the “ipv6.disable=1” to the boot options
when GRUB is selecting the kernel (temporary), or edit /boot/grub/menu.lst
(permanent). You can do that edit with YaST => System => Boot Loader, or any
editor running as root. I use ‘vi /boot…’, but vi is likely not for you. You
should get used to this change as 11.3 will likely have ipv6 built in.

As to your problem connecting to the Internet, you likely have either the
routing problem and/or a problem with DHCP. Please post the output of

/sbin/route -n
cat /etc/resolv.conf
