I experienced this issue on gentoo. I eventually figured out that it was caused by power management for the wireless device. Check whether your kernel was built with CONFIG_CFG80211_DEFAULT_PS. I can transfer data all night without the speed drop if I disable this option. As an alternative to rebuilding your kernel, there may be a boot option to disable power management, or you can try iwconfig wlan0 power off, but I get Operation not supported with iwconfig and I'm not sure why. -- iwl3945 slow down after some time to 100kbps, unload/load module return speed to 1.5mbps https://bugs.launchpad.net/bugs/340418 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

All this 'slowlyness' of certain netcards started with kernel 2.6.25 or 2.6.26. I have the same problem since with my rt2500 (Belkin PCMCIA). In the beginning of this problem, I could work around it for Puppy, Ubuntu and Mandriva. But when it came to kernel 2.6.28 that work-around didn't work any more. As you can see (read) the problem is been around for a long time now. And I can see that this bug is in progress. But that doesn't help those who are 'infected' by this bug. For what it's worth, I'll note the work-around again here.

I have the same problem using an apple airport express as AP. In my case the problem is clearly related to distance to the AP and signal strength.

evgheni, The thing that's weird is that, for me, the signal strength seems fine. It's consistently in the -70 to -60dBm range (40-50/70 in link quality). But yeah, it seems that the Intel driver is quite poor. Infact, I would almost say that I've had better luck with ndiswrapper.

Hi Nick, I had the same problem for at least two years. It appeared on Belkin and Netgear routers. The problem only appears when signal is quite low. Then the card scales down the speed and being unable to raise it back. Reconnecting usually helps for a few minutes, but then the same problem.

I think that everyone here that is having the issue should report which access point they are having the issue with and whether the problem can be replicated with a different access point. It seems that quite a few people that are having this issue (myself included) are using the Linksys WRT54GL router, and some have reported that the issue goes away when using a different access point. I'm using an Intel 3945ABG card in my Dell XPS m1330 in Karmic (Kernel 2.6.31-17-generic) and I'm having a similar issue. For the first 20-30 minutes after the connection is established, it works fine at a full 7mbit. However, after that point, it begins to degrade until I rmmod/modprobe iwl3945...and the cycle continues. I haven't noticed the issue with a Ubiquiti NS2L AP, so I'm starting to wonder if this is related to the WRT54GL. -- iwl3945 slow down after some time to 100kbps, unload/load module return speed to 1.5mbps https://bugs.launchpad.net/bugs/340418 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

None of the hints to improve the download/upload transfer rate in this thread actually helped me. What helped me was to replace my WLAN-router. I had a Linksys WRT54GL which did not give me a proper transfer rate. I complained to the salesman who gave me a new one (a new Linksys WRT54GL). With the new one I got exactly the same response. Then I bought a cheap DLINK-router just to test, and wow - it worked like anything. After a week I still have about 7Mbit/s download speed.
