J!, see previous posts, the problem usually shows up with high transfer speeds over wireless. If your AP is g, 1.2MBps takes approximately half the net available bandwidth, so it's bound to cause the problem.
narnie, I followed the hint about the .30 kernel. I don't recall all the packages that I had to manually install with dpkg, but the only ones apart from the recognizable kernel packages were virtualbox and nvidia modules. Everything else continued to work OK. I'm sorry to tell that the 2.6.30-10 kernel didn't help at all, either with standard /sys parameters or with the "iwconfig wlan0 power on" trick, on both 2.4 and 5.7 GHz APs. I did notice though an improvement on speed on large file transfers (while the connection is on, of course:-)): from the usual appalling high 2s to low 3s MBps to 4--5 MBps, sometimes also up to 5--6 MBps. Another benefit of the new kernel, as it looks so far, is the robustness of suspend-to-ram. So far the machine (D830 with Nvidia Quadro NVS140) has always woken up from suspend, whereas with the original 9.04 kernel it wouldn't about 30--50% of the attempts. This alone might justify the hassle. -- [Jaunty] Intel wireless 3945ABG is unstable and disconnects frequently https://bugs.launchpad.net/bugs/348204 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
