Want to upgrade antennas on my router do I need to upgrade all 3 ?

[jamieuk23]

Hi my router has 3 antennas on it and my Wifi signal in a certain room is quite poor so am looking to upgrade the antennas. My question is do I need to fork out and replace all 3 antennas ? or do I only need to replace a certain one that controls the Wifi ?

My router is a DrayTek Vigor 2710n

Thanks!

802.11n uses MiMo (mulit-in, multi-out) to help coverage and bandwidth. So yes, you would need to upgrade all three to get best results.

There isn't "a certain one that controls the Wifi", all three are used.

Have you contacted DrayTek for their advice? I would expect them to be able to help or give advice.
