Title:
Need support for WiMax cards management
Status in “network-manager” package in Ubuntu:
Incomplete
Bug description:
Binary package hint: network-manager
Currently network-manager does not provide support for WiMax cards available.
At the moment I am aware of at least two vendors providing WiMAX NICs: Intel
and Samsung. I have an Intel mini-PCI wireless card. Though there are both
firmware and kernel module in current 9.10 kernel so my device is properly
detected, they are not enough to start using the NIC.
I had to perform the following actions before i was able to connect:
1) Download official sources for `wimaxd` daemon and supplicant libraries
from an official Intel site http://linuxwimax.org
2) Build them, install them.
3) Get XML configuration files specific for my particular provider (taken
from CD distributive supplied for Windows)
4) As superuser run 'wimaxd; wimaxcu ron; wimaxcu connect network 15' to
connect to the provider ("Yota" brand)
The current issue is that this NIC can operate in only one mode at the
time: either WiFi or WiMAX, so I need to bring wlan0 down before
connecting to Wimax and vice-versa. And, while I use NM to manage
WiFi, this is inconvenient.
I am sure it would be great if all or at least part of this actions
can be done through some GUI configurator accessible from network-
manager.
Currently I plan to use some script (maybe incorporate it into my
ifupdown cfg) to switch between the NIC operation modes (taken from
http://icelord.net/wordpress/archives/1151):
STATE=`sudo wimaxcu status system| awk '{print $4}'`
if [ "$STATE" = "OFF." ]
then
beep
sudo iwconfig wlan0 tx off
sudo ifconfig wmx0 up
sleep 0.1s
sudo wimaxcu ron
sleep 2s
sudo wimaxcu connect network 15
sudo dhclient wmx0 &
else
beep
sleep 0.1s
beep
sleep 0.1s
bepp
sudo ifconfig wmx0 down
sudo wimaxcu roff
sleep 2s
sudo iwconfig wlan0 tx on
sleep 0.5s
sudo ifconfig wlan0 up
fi
Also, I am unaware what are the details of operation of Samsung WiMAX
NICs (they are sold as external USB deivces ) but I am sure that
madwimax project does support these cards in Linux.
So, some kind of plug in for network-manager is desirable. It should be able
to do the following things at least:
1) Detect Wimax cards
2) Detect that WiFi and WiMax cannot be used simultaneously.
3) Allow bringing interfaces up and down using proper backend utilities
(intel or madwimax)
