My MBP loses it's wireless signal and the pages just freeze. If I turn off wifi and turn it back on it will work again for a while, but then stop. This only happens sometimes. My phone, iPad, and other MacBook Air seem to work fine. I brought it to Apple and they let it run overnight and said they had no issues. Could it be a problem with my home network, even though all of the other devices are fine? I have it with me at work today to see if it has the same problems. Is there any program that I can run while here to see if it drops the signal, or just use it like I normally do at home and see if the issue happens. Thanks in advance for any suggestions.
