Bug description:
Binary package hint: network-manager
1) The release
Ubuntu version: Ubuntu 9.04 Jaunty Release: 9.04 64 BITS
2) The version of the package you are using
Package affected : network-manager 0.7.1~rc4.1.cf199a964-0ubuntu2
3) What you expected to happen
Estable connection.
If I kill NetworkManager and connect manually to the network using iwconfig
, the problem dissapear.
4)What happened instead
Frecuently signal gets interrupted, but not complety disconnected.
I guess it is related with the background network scanning but not sure. I
can notice while copying files on local network, watchins streaming movies or
with the ping command.
Approximatly each 90-120 seconds , a 5-8 seconds lag is generated.
--> Hardware :
Dell Wireless card 1515
Atheros AR928X chipset
#lspci | grep Atheros
06:00.0 Network controller: Atheros Communications Inc. AR928X Wireless
Network Adapter (PCI-Express) (rev 01)
--> Drivers :
Im not sure. Clean Ubuntu 9.04 installation detected my card, but could
not connect to networks until I installed
linux-backports-modules-jaunty-generic .
