I have a new HP Pavilion touchsmart laptop and right out of the box my wifi connected no problem. A few days and updates later here I am: I recently have a laptop with Windows 8. I did some windows updates and updated to windows 8.1 and now whenever I turn on my laptop, the initial wireless connection is showing "limited". Now I have googled and researched as many solutions as I can and I have already turned off the power management where my computer can "turn off wireless adapter device" if it is idol, that is not the problem. When I troubleshoot, it says the problem is with the adapter or access point and that the ip config is not evident. Now here's the weird part, I can walk into the room where my router is and it will connect immediately, then I can walk away into any other room in my home and it holds the connection without any problem. Second weird part, when using this computer at school, I have no problem connecting at all, and the router is not in my classroom.

The distance for a connection depends on the frequency that the router is using and the power output that the router is sending to its antennas.
So you can get the situation where your laptop can see the router because the router has a good signal can not send a signal to the router because the laptops wireless device is not sending a max power signal to its antenna. BY walking the laptop closer to the router you get the connection both ways and you get an IP address set up and you can send and see the internet. When you walk the computer further away, the connection starts to get transmission errors and automatically starts dropping the speed of the connection to the point that it will stay connected but my only do a very low/slow transmit data rate.
for most people you want to go into control panel, find the power management settings, find your wireless device, and tell your wireless device to use full performance when you are connected to line current (AC power). You can have it do this when you are on battery power but people forget to make the change and tend to shorten the battery life too much.

there are also environmental factors to consider, metal will absorb wireless signal. This includes the wire mesh in some walls that have stucco texture.
also, the higher frequency wireless signals don't bounce around corners as well as the lower frequency signals. IE higher frequency signal the more line of sight you need to have your laptop to your router.

my router can not send a good signal 8 feet thru a stucco wall to my xbox in another room. I use a $30 ethernet over electrical device route my ethernet from my router to a wall outlet, run the signals over the copper electrical wire to a second ethernet over electrical device in the other room.

(I could have put another router in that room on the same device if I wanted a fast connection, it work pretty well to get a fast connection (better than wireless) to a device where you don't want to run a physical cable.
