Hi there, i have common problem with this card:
i plug the usb tail, module loads automaticaly, networkmanager etablishes connection - everything goes well
but in a randrom time connection fails, and does not come back again until the module rtl8187 is reloaded.
i use latest stock arch kernel on x86_64 machine.
i`ve tried to solve this problem by solution posted in wiki - no result.
i`ve also tried compat-wireless-patched from aur - same stuff.
any help please?

It seems like a problem I had with Networkmanager, the wlan (eth is ok) contantly drops (every 10 minutes) since last kernel update, on every Wireless Lan... Is maybe this post similar?

I noticed that system logs doesn't report anything strange: after a disconnection I simply got nothing new i logs...:

PS: i use
04:00.0 Network controller: Intel Corporation WiFi Link 5100
08:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5784M Gigabit Ethernet PCIe (rev 10)
i.e. is not the same module but same kernel/arch/networkmanager stuff
In my honest opinion is a problem of networkmanager with the last kernel and not modules or so on... I should give a try to wicd.

Hm, but in my case onboard wireless card b43 with networkmanager and another wireless network works fine with no interruptions, and I`ve noticed that reconnection through rtl8187 fails untill i manualy reload module - this makes me blame the driver.
by the way

I`ve got that something makes rtl8187 drop the connection because of no probe response of the AP
but why? as i said b43 passeseverything well with different AP`s and rtl8187 breaks with every AP as well...
i`ve fond that it is most likely opendriver faulture and it is not fixed in any way besides ndiswraper..
i do not want to use ndiswraper so i diceded to make nonstandard solution:
i want to make a script which automaticaly makes rmmodrtl8187 && modprobe rtl8187 everytime when connection times out...
any help with this? i do not know how to make such thing. it should be a deamon to my mind? or can i use cpufreq on something like this as executor of command?

I starting to have the same problem... I'm use wpa_supplicant to connect to wifi... but this should work...
edit you rc.conf file to load the modules
MODULES=(mac80211 rtl8187)
sudo ifconfig wlan0 txpower 0
sudo ifconfig wlan0 rate 5.5M fixed
sudo wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf
sudo dhcpcd wlan0
adjusting rts and frag, is also optionally.. but i truelly believe the problem lies in the txpower, and rate..... .. atleast that was my problem.... try and let me know...
