Ubuntu Hardy/Intrepid Intel3945 Wireless

Hi,

I have a laptop with an Intel3945 wireless.

From what I can tell in both hardy and Intrepid I can see my Linksys 802.11b WAP and connect.

The log on the wap shows a connection by the MAC address of the wireless. But the laptop doesn't see anything on the network that the wap is part of.

I defined the static IP, DNS and gateway on the laptop.

I have a windows machine working fine wit the the same wap.

Any ideas what bit I'm missing?

Thanks,

Mac

  1. All I can tell you is that IWL2945 is my favorite wireless chipset, and I have it in several Ubuntu machines and it works just fine with open or with WPA-PSK networks, I haven’t used WEP in quite some time and you shouldn’t either, it’s lame.

    Check general connectivity by using ping, traceroute etc and you should find something, but I don’t think it’s a general issue with the chipset, it’s a networking problem.

    Do an “iwconfig wlan0″ on the client to make sure it’s actually associated properly, and do an “ifconfig wlan0″ to make sure the IP stuff is set up right.

    Now, the incessant LED blinking when associated that started with Intrepid is quite annoything, but I’m getting that fixed by /sys/class/leds fiddling.

  2. Hey,

    I’m a student and unfortunately a lot of universities use WEP. I have had NO such luck getting it to work with the Intel Chipset. I am known as the IT man and source of knowledge for a lot of my peers and its embarrassing to admit that I can’t help them with getting their Ubuntu laptops working properly. I was wondering if anyone else out there has similar trouble.

    I know this is pretty vague but if there is someone truly willing to help I can provide a lot more detail with log files.

    Thanks.

  3. Hi I have the exact same problem to connect to my university wireless network. I have a Dell Laptop with Intel 3945 ABG card, on Interprid. Actualy i can connect to both WEP and WPA network but there is nothing on the network (can’t access internet!). I would appreciate if any one had some fix! That’s a mess on windows everything work fine !?! They use LEAP (well can’t remember but i think it’s this one) security, maybe that’s the problem? Thanks!

  4. I had this problem. I kept getting kernel freezes or dropped off college network which uses WPA-Enterprise. What was required is to update the driver. I didn’t do it myself but was told that was what fixed it.

  5. Hi

    I have a similar and strange problem on a HP nx7400/Intel3945 dual-boot system (WinXP/Ubuntu Intrepid). In WinXP, no wireless problems. In Ubuntu I can see several wireless networks in my neighborhood (Open/WAP/WEP/WEP2) but just not my own (Netgear FWH114P) router. I have changed encryption settings on the router, I have tried to manually connect to it, nothing works. I don’t use MAC address screening in the router

    Prior to upgrading to Intrepid I was running Ubuntu Hardy without any wireless problems(!). I have tied to boot Hardy off the live CD just to check but that didn’t for some reason work either.

  6. If you are in Europe and using a European only wifi channel (such as channel 12 or 13) note that Intrepid by default does not use these channels. It is US by default regardless of your region. You need to add the following line to /etc/modprobe.d/options :

    options cfg80211 ieee80211_regdom=”EU”

  7. Hi, I am in South Africa, using D-Link wireless, and I am having the same problem. I can see my neighbours’ wireless, several of them, but not my own. All other PCs in the house (several of them) can see it no problem, just not the one with the Intel3945 card. Has anyone solved this yet?

  8. Yeah, there seems to be a bug in intrepid’s wireless switch. I have had the the very same problem i.e: started with Heron -> upgraded to Intrepid.. then dead wireless.

    Check launchpad for your chipset issues. Don’t loose hope quite yet. Believe me.

    I only had to update ‘nm-applet’ and ‘network-manager’, kde users try ‘kdnetwork-manager’ or some similar update.

    God speed

  9. Gnusci,

    You said:

    Try installing the latest driver:

    http://ipw3945.sourceforge.net

    From the project website:

    Note, this project is deprecated. The development is switched to the iwlwifi project (no binary daemon required!).

    That website states:

    “The iwlwifi driver has been merged into mainline kernel since 2.6.24. If you are using kernels after this release, please use the intree (drivers/net/wireless/iwlwifi) driver directly. After 2.6.26 the intree driver iwlagn also supports the new 5100BG, 5100ABG, 5100AGN, 5300AGN and 5350AGN series hardwares.

    HTH anyone
