Wireless home network again

For more than a month, husband is disabling the wireless home network. So, it ends up that all computers are wired to have an internet connection. He decided to disable the wireless, since there are so many intrusions in our wireless home network. It’s sort of internet threat for our personal records. But after he figured out how to hide our wireless home network, we are now using wireless internet again. To make everything safe, he keeps on monitoring it every morning (before going to work) to see if there are some intrusions and also when he will be home from work. So far, husband said there are no intrusions of our wireless home network presently!
