>Description:
Realtek 802.11n WLAN Adapter, RTL8188CUS stop working with high rf input. The usb adapter ENUWI-1X45 works without the external antenna , but when the antenna is connected, the led freeze (light on) and lost the connection.In 6.0_RC2 work good but have less sensitivity like in the comment: http://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=47723

--------------------------------

dmesg
urtwn0 at uhub1 port 1
urtwn0: Realtek 802.11n WLAN Adapter, rev 2.00/2.00, addr 2
urtwn0: MAC/BB RTL8188CUS, RF 6052 1T1R, address fc:8f:xx:xx:xx:xx
urtwn0: 1 rx pipe, 2 tx pipes
urtwn0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
urtwn0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps

--------------------------------

With the realtek binary works with and without antenna in windows and linux , so its not hw or mechanical issue.



>How-To-Repeat:
Attach the usb adapter with no antenna (works), and then connect the antenna (instantly stop working).
>Fix:
