Wireless Connection at FI MU during TSD 2004

The detailed instructions for connecting conference participants' notebooks to the wireless network at FI MU are divide into

The Instructions for Windows OS

original Czech instructions for Windows OS can be found here

After plugging in an external wireless card, new icon indicating the connection will be displayed in the right bottom corner of the display.

network connection icon

After double clicking this icon, the dialog below will be opened. Now, you need to select the wireless network name wlan_fi and press the connect button. In case the wlan_fi network is not displayed in the list, you are probably in a place with a bad signal. Otherwise please contact the OC technicians.

network selection dialog

Now, you need to check correct network settings. Click with right mouse button the My Network Places icon and select the Properties item. Next click with right button the icon for wireless connection, e.g.

dhcp settings

Then select the Internet Protocol (TCP/IP) item and click the Properties button. Edit the newly opened dialog according to the example below (i.e. set 'Obtain an IP address automatically' and 'Obtain DNS server address automatically' through DHCP) and press the OK button.

dhcp settings

The check of correct IP address assigning can be done at the command line with running the command ipconfig. The assigned addresses are always in the range of 147.251.51.*.

IP address check

After successful processing of the previous steps, your access to Internet is opened now.

UTP cable connection

After connecting the cable, you need to check the correct network settings similarly as for the wireless card connection. The check of the correct IP address assigning is also the same as above. The problems with bad signal cannot happen here.

The Instructions for Linux OS

The Proxim Orinoco cards are too new for Linux to be installed without difficulties. If you are an experienced user, you may try to get it working with the madwifi project, but you would have to compile a new kernel module with binary parts included :-(.

UTP cable connection

Configuration: The IP address is assigned by the DHCP protocol. There are two DHCP clients in Linux - pump and dhcpcd. You can obtain an IP address with one of the following commands:

# /sbin/dhcpcd -d eth0


# /sbin/pump -i eth0

Functionality checking:The obtained IP address is displayed with ifconfig:

# /sbin/ifconfig eth0

eth0      Link encap:Ethernet  HWaddr 00:02:2D:1B:43:0A  
          inet addr:  Bcast:  Mask:
          RX packets:351430 errors:0 dropped:0 overruns:0 frame:0
          TX packets:371 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100 
          RX bytes:19014995 (18.1 Mb)  TX bytes:111468 (108.8 Kb)
          Interrupt:12 Base address:0x100 

Look at the inet addr whose value should start with 147.251.51.

Then check, if you can reach the router in the network 51:

# ping -n -c 3
PING ( from : 56(84) bytes of data.
64 bytes from icmp_seq=0 ttl=255 time=2.330 msec
64 bytes from icmp_seq=1 ttl=255 time=2.202 msec
64 bytes from icmp_seq=2 ttl=255 time=2.240 msec

--- ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max/mdev = 2.202/2.257/2.330/0.066 ms

And finally check, that DNS is working correctly. DHCP client should change the file /etc/resolv.conf to:

domain fi.muni.cz
search fi.muni.cz

Functionality checking: Try ping to some computer outside of FI MU network, e.g.:

# ping -c 3 ns.muni.cz
PING ns.muni.cz ( from : 56(84) bytes of data.
64 bytes from aragorn.ics.muni.cz ( icmp_seq=0 ttl=252 time=4.300 msec
64 bytes from aragorn.ics.muni.cz ( icmp_seq=1 ttl=252 time=2.607 msec
64 bytes from aragorn.ics.muni.cz ( icmp_seq=2 ttl=252 time=2.116 msec

--- ns.muni.cz ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max/mdev = 2.116/3.007/4.300/0.937 ms

Now, the network connection should be fully functional. Run your favourite browser and try your favourite WWW page or so.
