Wired or Wireless?
Wireless is more expensive, so you need to consider do you actually need wireless connection. Basically if you move around with your device then you will need a wireless connection, otherwise stick to your wired connection.

Latency can occur using wired and wireless, however it happens more so with wireless, if it happens with a wired connection then it is probably a problem with your broadband. Bandwidth is how much giga bits you can download per second.
