This problem still is around :(. I have tried Kubuntu 15.04/15.10 and
Netrunner 16 and the RTL8187 card is alive and finds the router (and
internet) right after login. But a few seconds later the connection is
dead although the network manager applet, iwconfig and my router's
clients list still show the  connection as being alive and good. But no
ping to the router is possible anymore.

The card is identified by lsusb as Bus 001 Device 002: ID 0bda:8187
Realtek Semiconductor Corp. RTL8187 Wireless Adapter & lsmod shows two
modules used by rtl8187: mac80211 and cfg80211 (Kernel 3.19).

  Hy!

  I have a notebook with an integrated rtl8187 based wifi.
  Now I switched to hardy, and I hoping if my wifi now works without ndiswrapper, because the driver is now in the mainline kernel...
  But my problem is still exists :S The link quality of the wifi connection is very poor... I mean, the driver reports the real connection srenght, but my connection LAGGS if I move away from my ap only about 4-5 meters, then if I ping the ap, I got 50% packet loss, and at about 8 meters, my connection unusable, when the driver reports 60% connection srenght... I'm sure my wifi works, because I tested it on window$ and with ndiswrapper, and with they, I got good results, but with ndiswrapper, other problems exists :S

  Thanks for your help!
  ...and sorry because my baad English!
