Home Learn Linux Linux Answers Audio/Video AM I having a driver issue b43, or something else?
  • What card (chipset) are you using? What driver and what firmware do you have installed. What is a network magic front end? Did you look in /var/log/messages or /var/log/dmesg and see if there are any errors pertaining to your wireless card?
    We need some more specific info in order to get some idea on how to diagnose your problem.

  • Network Magic is a Windows program. What are you using in Ubuntu? Are you having a problem only in Ubuntu or do it happen in Windows also?

  • Are you using ndiswrapper to wrap the driver? I have a PCMCIA card with a BCM43xx chipset, and it works great with ndiswrapper on an G network. Haven't tried it on an N network.

  • I would suggest checking your wireless access point logs and see if it is dropping the connection. Possibly try rebooting the router and see if it holds a connection. This is pretty vague and may not be a system/OS issue at all if the system works fine at another location.

  • I have had nothing but bad experiences with Broadcom in Linux. Just about every laptop I own came with a Broadcom chip. I can confirm switching to Atheros AR5B91 chip has fixed the problem on all of them, without extra drivers needed. Whether or not you can change the card depends on your warranty, and AR5B91 is a full card, so you have to have a slot for it. I get them for ~$15 on eBay.

  • This sounds to me like it's not a driver related issue at all, since the card works in another location. Please provide the model number of the card (lspci or lsub might help you identify the card). I am curious ot know if the card is capable of tuning the 5 Ghz band. Also, you said that your Access Point is 802.11n capable. what make and model is it? Do you know if it's capable of tunning to 5 Ghz?

    The rason for the line of questioning is that it sounds to me like you may be running into either a high ammount of noise or a high ammount of interference at your house. The 2.4 Ghz spectrum is generally pretty cluttered.

    actually, please provide the output of "iwlist scan" for me, too. That should help confirm or disuage some of my suspiscions.

  • Either there is a bug in the kernel driver for your wireless adapter or your adapter is faulty and needs replacing.
    Consider upgrading the Linux kernel using your distribution's software package manager or replace Ubuntu with Fedora 12, which has the new open Broadcom wireless firmware (openfwwf) Available. If your card is supported by openwwf, it will work right off the bat using Fedora 12.
