Bug Description
Ubuntu 11.10 Oneiric ocelot Desktop 64-AMD. Lenovo Ideapad s205
After blacklisting acer_wmi in /etc/modprobe.
But Network speed drops very fast and after1-2 minutes it is stable under 50-70Kb/s, and other devices on the wifi network looses their connection.
Bug #651778 is an older bug (unsolved) about R3090 but concerns RT3090 being unstable, it does not appear to be the same bug.
On Ubuntu forums there are several threads with different solutions: Installing older version of Markus Heberling's Ralink 3090 driver, install compat-wireless driver, but some solutions are not consistent for different users on the same hardware.
WORKAROUND: In Oneiric with kernel >= 3.0.0.13, blacklist acer_wmi , and use the rt2x00 drivers from https:/
Add to /etc/rc.local:
iwconfig wlan0 power off
WORKAROUND: In release prior to Precise, I installed this driver: https:/
It did not work with newer driver.
Blacklisted "acer_wmi" in /etc/modprobe.
Added "rt3090sta" to /etc/modules
Original source: http://
WORKAROUND: In Precise, once the Ralink driver is downloaded, unpack and edit the file ../common/cmm_wpa.c :
Code:
UCHAR PrimaryRsnie;
BOOLEAN bMixCipher = FALSE; // indicate the pairwise and group cipher are different
UCHAR p_offset;
- WPA_MIX_PAIR_CIPHER FlexibleCipher = MIX_CIPHER_NOTUSE; // it provide the more flexible cipher combination in WPA-WPA2 and TKIPAES mode
+ WPA_MIX_PAIR_CIPHER FlexibleCipher = WPA_TKIPAES_
then lastly in the file ../os/linux/
Code:
HAS_GREENAP_
#Support MAC80211 LINUX-only function
-HAS_CFG80211_
+HAS_CFG80211_
#Support RFKILL hardware block/unblock LINUX-only function
HAS_RFKILL_
Run "sudo make ; sudo make install", blacklist "acer_wmi" in /etc/modprobe.
It's helpful to blacklist rt2800pci so the system doesn't use this - it will use the new rt3090sta/rt2860 instead after a reboot...
