R7800 customer query and introduction

  You have purchased a very powerful router. 

  Recommend you use your original antennas.  Longer antennas will give you a little bit more range but the longer they are the more directional they are.  Almost all antennas for use with routers are of a dipole type.  They radiate out in a doughnut or toroidal pattern.  The longer the antenna the flatter the pattern and the more difficult it is to get good reception.

  The best configuration for your router is the default that it comes with out of the box.  Any configurations that you do will most likely slow down your router.  QOS is especially bad at slowing down the router and should only be used with very slow connections like DSL at 5 Mbps.

  There are some configuration items you should definitely edit.

  First of all CHANGE THE PASSWORD from the default to a good one you can remember. (Not 1234, abcd, qwerty, or other common password)  YOU WILL GET HACKED IF YOU DON'T CHANGE IT.

  Second reserve all your IP addresses.  Turn on all your network devices, especially cell phones,  and open up a login window to your router.  Go to the Advanced tab and select Setup and LAN Setup under that.  Add each address one by one using the +Add button at the bottom of the screen.  I always click the apply button at the top of the screen when I finish adding all the addresses but that might not be required.

  Third I don't have any other routers around me so I turn off the play nicely with others setting of Enable 20/40 MHz Coexistence.  Under the Advanced tab select Advanced Setup then Wireless Settings.  Uncheck the Enable 20/40 MHz Coexistence box. (Second box from the top.)  This has helped to increase the throughput of my 2.4Ghz devices.

  If you need to open up any ports just remember that there is a cumulative performance hit for every instance.
