When I try to download something, for example from torrents, I see ping up (up to 500-800ms), slow speed (<1mbit/s) and packets lost. In windows its works fine, ping didnt up, download speed 14mbit/s. So if I want to download something, I need to reboot from ubuntu to windows, or wait for download at low speed in ubuntu. And it's not good=( Thanks, and sorry my bad english. laptop:~$ uname -a Linux mike-laptop 2.6.38-10-generic #44-Ubuntu SMP Thu Jun 2 21:32:22 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux laptop:~$ modprobe --show-depends rtl8187 insmod /lib/modules/2.6.38-10-generic/updates/drivers/misc/eeprom/eeprom_93cx6.ko insmod /lib/modules/2.6.38-10-generic/updates/net/wireless/cfg80211.ko insmod /lib/modules/2.6.38-10-generic/updates/net/mac80211/mac80211.ko insmod /lib/modules/2.6.38-10-generic/updates/drivers/net/wireless/rtl818x/rtl8187/rtl8187.ko laptop:~$ sudo lsusb -d 0bda:8187 Bus 001 Device 004: ID 0bda:8187 Realtek Semiconductor Corp.
