Wifi antenna aiming

Does it make a difference if I adjust the three antennas on my wifi router? There are a couple of areas of weak signals in my split-level house. Is it just a hit-or-miss experiment of moving the antenna orientation, or is there a method?

Ideally you want the router centrally located. But if you cant, you want to point the antenna towards you computer appliances. But that will only marginally help if you're having troubles getting signal to all floors. You may want to look at a signal booster. There are serval ways of doing that.

"stick" looking antennas do not radiate out the ends. Do not aim the tip of the antenna where you want a signal. Align the antenna 90 degrees to where you want good reception. In the image below the antenna is vertical through the center of the doughnut with no signal straight out the top and all the energy sent out in a doughnut around the antenna.

Download a Wi-Fi signal strength app onto your phone or tablet.
Then use that to set the antenna and router location and orientation.

Often it is what is between the router and the location re: ducting, wall etc.

You're correct about the signal radiating radially as opposed to vertically from the antenna tip. But aiming the antenna towards your intended appliances will aim that "donut" to the direction you want.
I've got an extender with three rotating antennae. Aiming those antennae makes a very definite difference between getting a signal and not getting any signal.

Signal strength is influenced primarily by distance, environment (walls and ceilings, for example), and interference from other devices. Ideally you want to place the router in a place that minimizes the impact of these factors. Moving the router even a few feet horizontal or vertical could have a substantial impact.

Beyond that, other changes (except boosters) will have a minimal impact.

When all is said and done.... it's pretty much trial and error.

Split-level homes can be tough when it comes to wi-fi. If it's a big problem, look into Powerline Adapters. They work better than typical wifi-repeaters, imo. https://www.google.com/url?sa=t&rct=...v3y_wQTFHVjXJ0
