Hello prandi and welcome to Linux!

First of all you shouldn't need to set and DNS or IP addresses as your router will do this automatically when you manage to connect to it.

Now to actually connect to your router… On the bottom right hand side of your taskbar you should see a network icon (I’m not sure what it looks like). Clicking it with hopefully display a similar dialog to:



The only difference being that it should list your router's name. Click on your router and it will ask you to enter your WEP key. Enter it and click okay and you should be connected

Give a shout if you have any problems

thanx!!!i tried to do the same earlier but after i enter the wep key,it say connecting to Utstarcom(my router) and then nothing!!!but sometime a get connection on network interface wlan0 failed(something of that sort),wats going on

I can't say without seeing the full error message but a common problem is that you are entering the wrong WEP key.

You may need to connect to the router using an Ethernet cable to find the correct WEP key but hopefully it will be written somewhere on the router itself though. Let me know if you need any help finding it

Sometimes iwconfig (the underlying wireless configuration program) can be finicky about router settings. I've found that it does actually matter if the router is in shared or open mode; it tends to connect easier if it's open.

its the same problem Connection on network interface wlan0 failed,,sometimes kde also reports crash,,and is in open mode,and wireless mode is infrastructure

I wonder then if interference is a factor. Do you have a lot of neighboring wifi's? Any on the same or worse, neighboring channels?

In the router settings, do you know if it is doing any kind of MAC filtering, and if so, make sure there are no typos. Make sure the DHCP server is on (that is what tells the computer how to configure itself to your router's network).

Can you post the full error message? Also when it happens can you post the output of:

tail /var/log/messages

If it is an interference problem i would recommend running netstumbler (netstumbler.com/downloads)in windows and see what other peoples routers in your area have there channels set to, the most common one is 1 and basically changed the channel on your router to one that is not used by any one else's router in your area.

hope this helps
i would recommend noting down this information as it helps to reduce wireless interference when connecting to your router

if you need any more help send us a PM

If the wireless is working, you don't need to run widows to see what channels neighboring wireless networks are using. Just run this command.

iwlist scan
