 Posted: Fri Feb 25, 2005 5:54 am Post subject: Wireless Won't Start Up Correctly (ipw2100) |
 |
|
I have both net.eth0 and net.eth1 in my /etc/init.d. They are both
pointing to net.lo. From what I've read, this is correct. It seems
to work correctly on boot, as well. First, net.eth0 is checked. If
that fails, then net.eth1 tries to start.
Here's the problem. For eth1 to appear, I first need to modprobe
ipw2100. I do this by putting it in my /etc/conf.d/local.start file.
Unfortunately, not only does this enable eth1, it also does some other
stuff, like running dhcp on it.
When it comes time to check net.eth0, if it is plugged in, dhcp will
also be run on that as well. When I boot into gnome, both eth0 and
eth1 are running dhcp, and both have IPs, and it conflicts. My
internet doesn't work. To get my internet to work, I have to do
/etc/init.d/net.eth1 stop.
If net.eth0 is not plugged in, however, net.eth1 then tries to start.
However, I get an error stating that "dhcp is already enabled on
eth1". This is because of the modprobe ipw2100 step. Since that
fails and eth0 isn't connected either, my internet refuses to work
there too.
It's still kinda fuzzy, and I'm not sure how it all works. I think
it'd be a good idea to post it somewhere and see if anyone replies. |

Ok,
First of all there's a bunch of scripts to handle modprobing on startup.
| Code: | | echo ipw2100 > /etc/modules.autoload.d/kernel-2.6 |
And remove your modprobe line from local.start
Next edit /etc/conf.d/net to reflect your setup and stop dhcpcd starting against each card. |

Okay, I changed ipw2100 from local to kernel-2.6 and things still didn't seem to work.
I do have two lines in my /etc/conf.d/net dhcpcd_eth0="-t 10" and dhcpcd_eth1="-t 10" to have a timeout set on the my cards. Should this be removed?
Thanks for your help. |

Ninja,
All your ethernet network devices (e.g. the ipw2100 card) should use an init script other than net.lo. If you dont have a "real" net.eth0 script (in stead of a link) use mine I will post it at the end of the message (it is the default gentoo net.eth0)
| Code: | ls -al /etc/init.d/net.eth*
-rwxr-xr-x 1 root root 9776 Apr 3 23:05 net.eth0
lrwxrwxrwx 1 root root 8 Apr 4 03:37 net.eth1 -> net.eth0
|
These are configured in the /etc/conf.d/net file (you did this according to you dhcp comment) => be sure that you not have enabled a static ip as well.
Furthermore: every network card needs a specific driver in order to function properly. These drivers will be loaded on startup if you put them in the kernel-2.6 file as mentioned earlier. This means for your wireless card the ipw2100 module, but for any other card you will ALSO need to put the module in this file. the order in which the modules are loaded will also be the order in which the ethernet devices are numbered:
in the kernel-2.6 file:
ipw2100 this will be eth0
e100 (my other networkcard) this will be eth1
Good luck, hope you get it working!
