Question
Tyler is setting up a wireless network for his business that he runs out of his home. He has followed all the directions from the ISP as well as the wireless router manual. He does not have any encryption set and the SSID is being broadcast. On his laptop, he can pick up the wireless signal for short periods of time, but then the connection drops and the signal goes away. Eventually the wireless signal shows back up, but drops intermittently. What could be Tyler issue with his home wireless network?

Explanation
Standard 802.11b/g Wi-Fi operates on the 2.4 GHz frequency band. Many cordless phones also operate on 2.4 GHz, and when the phone is in use or even just active, it can cause significant radio frequency interference that disrupts the Wi-Fi signal. This matches the described symptom perfectly - the connection works intermittently and drops unpredictably, which is characteristic of an RF interference source sharing the same frequency band. CB radios (A) and satellite TV (C) operate on different frequencies and wouldn't cause this. Wired computers (D) do not emit wireless interference.
