I've been using Ubuntu for a few weeks now, and since then I've been unable to solve my wireless problem. Every time time I run some intense networking like DL and streaming my wireless crashes, or if I just give it enough time it crash as well. My only option is to reboot my computer. I've been trying a bunch of different solutions to no avail.
Here what I get when I run
iwconfig when it's still working :
lo no wireless extensions. wlan0 IEEE 802.11bgn ESSID:"freebox_ISPCGS" Mode:Managed Frequency:2.452 GHz Access Point: 00:24:D4:63:66:64 Bit Rate=72.2 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr=2347 B Fragment thr:off Power Management:off Link Quality=70/70 Signal level=-35 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 eth0 no wireless extensions.
MY computer is a Compaq Presario CQ56 with a RTL8191SEvA Wireless LAN Controller
