|Your Smart phone and iPad must be close enough to the router such that they're getting a strong enough wireless connection to the router. The Smart phone's and iPad's wireless network adapter may require a stronger wireless connection than your computer's wireless network adapter (if that's what you're using) does. |
On the other hand, a friend of mine had a Belkin n150 model that became defective. The network ports on it no longer worked properly. It was covered by it's one year ? warranty, he sent it away, they replaced it and shipped it to him for free, and the same model now works fine.
