I have a Sony Vaio SVE1512B1EW and have connected it to my wireless. Works absolutely fine. However recently whenever I turn on my laptop the Internet will work for 2 minutes and then not work, even though it says its connected at full bar signal. When this happened again I tried the Internet on a different laptop and found that it is not the wireless! What will I do? It's telling me there's a connection but not working? Help please!!!
