I was skeptical, but a fan does seem to help

So BTW I get a B66 and N71 and here is the current data.

I just got 75 down and 25 up.

Also I need the mesh of the Google Wifi but it does seem to slow things down. For instance if I turn on the can wifi that will be a bit faster like 90ish vs 75 ish. Same goes for wired most of my rooms are wired for ethernet (previous owner put 2 in every room except for the room the can is in now) so if I take a wired connection it will also be 90 ish. So it should not really matter but the Google Wifi does seem to add a performance hit. I am just noting this as when I test I always test on the same setup so I am getting consistent results.

I was really thinking of getting that external ant not sure if it is worth it as if this can stay stable at these speeds it will run my home as is.
