As far as I understand, the DIR-825 has two antennas: one is labeled as 2.4 Ghz and the other one as a 5 Ghz antenna. My question is: how does the router achieve 802.11n speeds? What if I used the 5 Ghz bando only? will I still get high speeds? Will the router use both antennas?
The problem here is that I need to use the 5 Ghz band (only) and get 802.11n speeds. But something tells me that the DIR-825 router achieves N speeds thanks to the fact that it uses both 2.4 and 5 Ghz bands (and using both antennas) at the same time.
If this is the case, is there any other D-Link N router that would let me get N speeds by using the 5 Ghz band only?
The router uses 2 dual band antennas, each antenna is capable of 2.4 and 5 Ghz, each antenna is labeled 2.4/5 Ghz.
If you want to use 5 Ghz only, simply turn off the 2.4 Ghz radio in the software.
I currently have my 5 Ghz radio turned off, no sense in causing RF pollution if you don't need to!
I believe the only option for 5 Ghz is "N".
They recommend that you use D-Link cards for 100% compatibility and maximum speed.
