Is initiating a WiFi connection more sensitive than simply keeping an existing connection running?

I’m on the fringe of Wi-Fi and cannot connect. Why, when I can get closer, I
can connect and when I return to the same spot, already connected, it stays
online at that spot? The place where I could not connect now works if it’s
already connected when I move there?

matters.

Connecting to WiFi

So, I believe that the actual process of establishing a Wi-Fi connection is,
in fact, more complex than simply using an existing connection.

I believe that the hardware actually has to do some interesting detection of
what frequencies are in use, and negotiate how to set up the connection, and so
forth. So it doesn’t surprise me that you may be able to take a solid
connection when you are closer to the access point – and then move to an area
where you wouldn’t be able to initiate a connection, but you would
still be able to use the connection you initiated.

Sharing Wifi

Now, the concern I have is that the right solution to this problem is to get
yourself another Wi-Fi hotspot. Get yourself coverage closer to the area in
which you are trying to connect in the first place.

Remember that Wi-Fi is yours… you need to have Wi-Fi from your own
internet connection.

If what you’re talking about is that you’re too far away from the coffee
shop that’s offering free Wi-Fi – that’s bad. You’re using their Wi-Fi
without their permission. They usually require that you come in and at least
have a cup of coffee and use the Wi-Fi on site.

If you’re actually within range of somebody else’s Wi-Fi and are using it
without their permission, that’s not something you should be doing.

On the other hand, if this is a Wi-Fi access point that you’ve set up on
your own internet connection at your home, or in your business, then the right
solution is to set up another wireless access point closer to where you want to
make the connection.

  1. I had the same problem with my WiFi at home. It turned out to be an interference with my neighbor’s and changing the router’s frequency channel did the trick.

  2. Here’s a simple fix that may solve WLAN signal strength issues for some: My TRENDnet Wireless-N router, located on one end of the 1st floor of our home, has 3 antennas. I selected it in the hope it would provide a good signal at the far end of the floor above. Though better than my previous router, the signal was borderline. So I took three small styrofoam cups and punched a hole in the bottom of each so they would slip down over the antennas, which then stick up just beyond the lip of each cup. I cut aluminum foil strips and taped them to line 180 degrees of the inside wall of each cup. Once the cups were in place, with their antennas centered, I rotated each cup so the foil was positioned to act as a reflector, directing the signal toward the far end of the house. The WLAN signal was then *much* stronger there! Problem solved in minutes, with just a few pennies worth of cups and foil. It saved the cost and hassle of installing a repeater or a hardwired system.
