modem, by plugging a standard CAT5 Ethernet patch cable
(sold separately) into your computer's RJ45 Ethernet port. If
your connection problem disappears, the problem lies in the
Wi-Fi
® part of your network.

check the access point vendor's Web site for recent firmware
upgrades. Problems with WEP keys, in particular, are
frequently addressed in new firmware releases.
