Problem still exists. It still looks and behaves the same. Signal strength is 15% and throughput is about 5.something Mbps. Instead of 54Mbps.

The chipset is now described as
[ 13.621424] usbcore: registered new interface driver rtl8187
[ 13.862659] phy0: hwaddr 00:15:af:07:e4:80, RTL8187vB (default) V1 + rtl8225z2

If it helps, "lsusb -vd 0bda:8187" reports it as:
