Installing a WLAN antenna 
Only the following routers support WLAN antennas: 
•  RT-MSR810-W 
•  RT-MSR810-W-LM 
•  RT-MSR810-W-DB 
•  RT-MSR810-W-LM-HK 
•  RT-MSR810-W-LM-GL 
You can install two WLAN antennas for the RT-MSR810-W, RT-MSR810-W-LM, RT-MSR810-W-
LM-HK, and RT-MSR810-W-LM-GL routers and four WLAN antennas for the RT-MSR810-W-DB 
router. 
To install a WLAN antenna: 
1.  Change the angle of the antenna orientation from vertical to horizontal. 
2.  Attach the antenna to the WLAN antenna port on the router. Do not over-tighten the antenna 
to avoid damage. 
For better signal receiving, change the antenna orientation to vertical.
