Need guide in repair network connection

ikky · March 8, 2011, 1:05pm

Hi all,

I have been installed 2 booting system (XP and Suse linux), and I have been configurated the Xp wireless connection too (Because the MAC address is collision with other user). It works…But, the problem is the linux network connection wont working even network connection status “automatic connected”. Detail problem is MAC address is collision with other MAC address, so from google I got information about changes the mac address. I tried the way (change the networks connection with static IP address), but, it wont solve my problem. The message I got, such as :

From sudo /usr/sbin/iwlist scan [ESSID:“ABCDF” (sample)]

For add on information, I used gnome mode, my notebook is ACER aspire 4770G and wireless intel link 5100 AGN driver.

After following thread “Getting yourwireless work”, I am sure I got a wrong way, but I dont have idea what it is. Is there someone have an advice or other user guide to repair MAC address in open suse linux enterprise v11?

Thank you alot…

Your driver is in place:

04:00.0 Network controller [0280]: Intel Corporation WiFi Link 5100 [8086:4232] 
    Kernel driver in use: iwlagn 
    Kernel modules: iwlagn

You say much about MAC addresses, but the only importance really is if you use access control, which allows access by MAC.

Perhaps the writer of the wireless guide will offer advice

Thank you for the information caf4926…

I wrote all information above, because I am little frustated. lol! lol! lol!

Okay, I am waiting the guide. Once more, thank you alot sir…

I think you’re confusing two terms… ‘MAC address’ and ‘IP Address’.

Typically with wireless networking you want the wireless router to assign your ip address, so there would be no need to change it.
The MAC address is built into your hardware and under normal circumstances wouldn’t be changed.

Go into YAST, select network card, and set it to use network manager (instead of traditional method, ifup).
Your DHCP server (wireless router) won’t assign the same IP Address to two different network cards. It can tell they are different because they have unique MAC Addresses.

Hi rodhuffaker,

Thank you for reply and I am Sorry that I make you confusing about MAC address and IP Address.
Btw, continuing my problem…Maybe this information gives you explanation clearly about my problem. I have change other IP address into own in windows from Network connection → Properties → Internet protocol (TCP/IP) → properties.Result, it work… But, I am not too familiar in suse linux. Is the setup same as windows?And, do you have a guide or advice?

Hmm… I have followed your instruction about YAST → Network card, but I cant find any word with “network card” even I tried using search option. Is network card same function with Internet protocol (TCP/IP) → properties?

Hmm… I have tried change the setup with static IP Address, it didnt worked. I put back into the default setup, it didnt worked too. 2 things that confused me are (first time) i guess the main problem just ip address (because I used other ip address). Then, from “ping -c 5 123.456.7.8” I know that I connect with wireless, but from “ping -5 66.70.73.150” I saw that i have not permission to browse internet (because linux read a collision ip address).

Hello all…

Is there someone know how to repair a collision IP address and check IP address in linux? From windows, I just go to command prompt and write ipconfig/all to check mine. Is it same as in linux? I mean, I just go to terminal and write the right command… If yes, can someone help with "what is the command to check ip address? Thank you…

/sbin/ifconfig

If you set up the interface to use DHCP, then there will be no IP collisions.
Static IP addresses seems to be a little complicated for your level of
experience. Not only will you avoid assigning of duplicate addresses, but the
network mask, the route settings, and the nameserver will be correct.
