I confirm that I have the same problem. It happens most of time when I use a lot of bandwidth. (video, simultaneous downloads etc)
My router is a TP-link TL-WR1043ND with WPA2 security with newest firmware. My laptop is a Packard Bell EasyNote TJ66 also with newest firmware. Other computers in my network (wired) don't have this problem. It seems that the problem must be found in Ubuntu. My laptop is dualboot and on the Mickeysoft-partition it has no problem with wireless. Another strange thing is, that on the router of my neighbours (also TP- link but without encryption) I don't have problems. -- wlan is unstable since lucid https://bugs.launchpad.net/bugs/575213 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
