HP Tc4400 Troubleshooting - Page 14

Quick checklist ■ Be sure that no other electronics, such as a cordless phone, a fax machine, or a microwave, are in close proximity to the wireless router (access point). ■ Be sure that no large metal surfaces are near the sides of the wireless router (access point). ■ Be sure that the wireless router (access point) is placed as high as possible in the room, such as on top of a bookcase. ■ Check the wireless router (access point) functionality and configuration. ❏ Temporarily disable any wireless encryption to see if the computer will connect to the wireless network. If the computer connects to the wireless network when encryption is disabled, verify that the computer and the wireless router (access point) are using the same security settings (Network Authentication, Data Encryption, Network Key, and Key Index). ❏ Change the wireless channel on the wireless router (access point). Normally channels 3, 6, and 11 are the optimal channels because they do not overlap each other. However, if multiple networks are detected in close proximity, and more than one is using the same channel, there may be interference.
