    Re: Asus x501a rt3970 wireless chip problem (kernel panic)

    If you reinstalled and lsmod shows that you are using rt2800pci, then what does rt2860 have to do with anything? My question for you is, after you loaded the driver parameter above, what exactly is not working? Your original question says kernel panics under load. Do you have that now?
    when the wifi chip gets a little bit of load i get kernel panic ive tryed this with ubuntu 12.10 and linux mint 14.

    Re: Asus x501a rt3970 wireless chip problem (kernel panic)

    I when i tryed rt2860 the wifi was alot better and got really good signal but as soon as i got some load on it i got kernel panic. so i reinstalled ubuntu to get the 2800 back. I tryed this on linux mint as well but then i though there the same thing nearly. so if there was a way to use rt2860 with out the kernel panic that would be great. that way my wifi would be good and be fast and great signal

    Re: Asus x501a rt3970 wireless chip problem (kernel panic)

    The driver rt2860sta is an old driver; development stopped when your device and many others were included in rt2800pci. I know of no way to get that antique to work in newer kernels such as 3.5.xx.

    I have been trying to help you troubleshoot the driver you DO have, rt2800pci. I have asked you twice about its performance with a driver parameter and twice I have gotten a reference to how your wireless device performed with rt2860sta, which won't work and isn't available.

    If you'd like to troubleshoot what you do have and what does work, at least, so far, partially, I'd be happy to help. If you want to tell me again how great rt2860sta was in the old days except for the occasional kernel panic, then I can't help you.

    What is the problem? Slow? Unstable? Kernel panic? Is the driver iwlwifi?
    Code:
    lsmod | grep iwl
    There are several driver parameters that we can try to help performance.

    Re: Asus x501a rt3970 wireless chip problem (kernel panic)

    sorry i should of said, its unstable the speed all over the place. signal poor as well is a lot better in windows. could it be the router like i said

    Driver is iwlwifi

    Code:
    jonny@The-Doctor:~$ lsmod | grep iwliwldvm                241871  0
    mac80211              549638  1 iwldvm
    iwlwifi               161598  1 iwldvm
    cfg80211              206741  3 iwldvm,mac80211,iwlwifi

    Let's see if a driver parameter helps:
    Code:
    sudo modprobe -r iwlwifi
    sudo modprobe iwlwifi 11n_disable=1
    If it helps, we can write a file and make it persistent.

    no luck still the same. ive tryed this on the 3.7 kernel and 3.5

    is there away to update the driver ? (if thats worth doing)

    it it make any difference moving to 12.04 LTS?

    You could try the compat-wireless package; however...
    (if thats worth doing)
    No, in my opinion. I have two or three Intel cards around here and I am using iwlwifi right now and it's rock solid in every respect, with or without compat-wireless. I am beginning to think this is the answer:
    could this be the router?
    I'd set it to WPA2 only, not some mixed mode WPA and WPA2 and I'd provisionally try disabling N speeds. If I remember correctly, you've had three devices and two kernels with the same problem.
