Maybe address bug with wg111v3 to linux driver rtl8187 (or kernel) implementation of AGC?
"The RTL8187B supports fast receiver Automatic Gain Control (AGC) and antenna diversity functions, and an adaptive transmit power control function to obtain better performance in the analog portions of the transceiver. It also has on-chip digital-to-analog converters and analog-to-digital converters for analog I and Q inputs and outputs, transmit TSSI and receiver RSSI inputs, and transmit and receiver AGC outputs. " quote is taken from the link http://www.realtek.com.tw/products/productsView.aspx?Langid=1&PNid=24&PFid=1&Level=6&Conn=5&ProdID=143 This part "adaptive transmit power control function to obtain better performance" i want to paraphrase "adaptive transmit power control function to make more trouble for linux users" :D -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/802902 Title: Realtek rtl8187b wireless chipset slow speed Status in The Linux Kernel: Invalid Status in “linux” package in Ubuntu: Fix Released Bug description: Hi, I have ubuntu 11.04, all updates, wifi chipset rtl8187B, kernel 2.6.38-10, and 14mbit/s internet connection. 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.
