My Toshiba Satellite L455-S5975 will not connect to my wireless internet. The only way i can get on the internet is by ethernet cable. It says that i am fully connected to the wireless internet but every time i try to get on an internet browser it will not load.

There are several things you can try. First, I would recommend resetting the router by unplugging the power cord than reconnecting. Many times, that solution works. Next, right click on the network connection icon in the lower right hand corner of the screen (normally it looks like two monitor screens). It should bring up a list of choices one of which is connect to internet. When you click on that, it should show all the wireless networks available in your area. Your wireless network should be listed too, show highlight that by left clicking on it, then, at the bottom of that screen, there should be a button that says "connect". Click on that, and you should be able to connect. When you were connected using an ethernet cable, were there any connectivity problems(e.g. losing your internet connection)? If so, you may have to upgrade the firmware to your wireless router. For that you would have to contact the manufacturer's technical support people and they can assist you with downloading the file. Good luck!
