The upload speed to the network stays normal (about 1Mbit/s) so this direction works quite well. What is worse is that if one loads data from the Internet with this slow download rate, ALL other computers in the local network are blocked - those machines are not able to down/upload anything. Reproducible: Always Steps to Reproduce: 1.Connect to the Router using KNetworkmanager. 2.Try to download something from the internet. 3.Watch the download rate going down to a maximum of 60 KByte and see all other computers internet connections stalled. Actual Results: Very low download rate, but still a working connection to the router. Expected Results: Normal download rate of at least the 20Mbit/s and no violaton of the network operations of other computers in the local network. Current kernel version is 3.1.10-1.9-desktop. The module used by the rt3090 are rt2800pci, rt2800lib, rt2x00usb and rt2x00lib. Disabling the hardware encryption (which is a feature of the rt2800pci module) does not better the situation (nothing conspicious in the dmesg log). Changing the router settings does not change the situation. (e.g. changing from WPA2-PSK [AES] or WPA-PSK [TKIP] + WPA2-PSK [AES]) Only possible solution so far: Download rt3090 and compile proprietary driver - it works. (of course blacklist all mentioned rt2xxx modules) Also, using the compat-wireless-kmp-desktop package does not change a thing. I do not know if this is already fixed with newer kernels, this seems to be the same issue as is reported here: http://rt2x00.serialmonkey.com/pipermail/users_rt2x00.serialmonkey.com/2011-... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
