 |
|
So I've been having a problem when using a wireless connection with the ipw3945 drivers.
If I'm doing a lengthy scp (like copying a cd image) to another computer (like my desktop) there's a really high chance that partway during the transfer, the ETA turns into "- stalled -" and then eventually times out. After that, my wireless connection completely fails to do anything, even pinging. And then when I try to do a modprobe -r ipw3945 to try and restart my wireless connection, there's a very high chance that it stalls, to the point where a CTRL-c can't stop it. I have to then CTRL-z to suspend then kill -9 the process. But even then, i still have several instances of ipw3945d running as well as the modprobe removal command, and no attempt at killing those processes succeed, at which point the only solution is to reboot my machine.
So what the heck is happening? |

Have you reset your router ?
What is the status of your AP when you run :

| Do you have any problem when you only surf the net or when you do a emerge --sync for exemple ? |

I had the same type of problem, at first I thought it had something to do with mounting a windows share with cifs so i started using smb.
At the same time I changed to iwlwifi-1.2.22 (a change in kernel config is required for this) and I have not had this problem since.
So, not sure what caused it exactly but iwlwifi and smb have solved it for me. |

@d2_racing: I'll check iwlist scan the next time it happens. As far as I can tell, it only really happens when I'm doing a lengthy scp, as otherwise I'm generally not doing something that is a continual stream of data.
@bosele: After reading your post, the idea of trying out iwlwifi sounded interesting but the package is masked. Is there a particular reason why this is masked (other than the generic description provided in the package.mask file)? |

I don't really know. Older kernels require a kernel patch maybe?
http://gentoo-wiki.com/HARDWARE_ipw3945 mentions a rate scaling problem (and workaround which i haven't used since my last install, with no ill effects)
Anyway it is quite stable here ~amd64. |

Can you post your emerge --info plz.
Maybe you are right, you should upgrade to kernel 2.6.23 if you have an older kernel. |

Yes, it works pretty well with a IPW3945ABG with a WEP and a WPA....but with the new IPW4965, that's an another thing. |

| Why are you using a i486 instead of a i686 ? |

| You have the latest kernel...so the problem is not a patch thing. |
