Very strange problem with my Dell XPS M 1330. I am using Ubuntu 12.10, network hardware is:
09:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5906M Fast Ethernet PCI Express (rev 02)0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
wlan0 IEEE 802.11abg ESSID:"organ" Mode:Managed Frequency:2.412 GHz Access Point: 54:E6:FC:C1:E5:32 Bit Rate=54 Mb/s Tx-Power=15 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=52/70 Signal level=-58 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:208 Invalid misc:32 Missed beacon:0
lo no wireless extensions. eth0 no wireless extensions.
When I download torrents with Transmission, if the download speed of all active torrents exceeds 2 MB, the computer will shut down. I have no other network issues, everything else works fine. But still, I am paying for much higher download speed and it is frustrating that I cannot get it when downloading stuff.
Do I have to change the network adaptor or it may be a software issue?
Thanks & let me know if need additional information
