Getting disconnected from server

I am using an Arduino Uno rev 3 with a WiFi shield to connect to a server that's being hosted on my computer. However, at random times the connection is dropped for no reason. Does anyone know why this might be happening?

(This is my first time using these forums, so if I need to provide any other information please let me know and I will be happy to do so.)

Presumably it's not happening for no reason.

The most likely explanation would be that the WiFi link is dropping out due to signal loss or interference.
