❖Connect your computer directly to your router or
broadband 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.
❖If you have enabled any security provisions (closed
system, MAC address filtering, Wired Equivalent Privacy
[WEP], etc.), 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.
The Windows® operating system wireless
management utility does not work.
If you are using an external Wi-Fi® adapter (a USB adapter,
or other variety), check if the adapter comes with its own
management utility. If it does, the utility may be disabling the
Windows® operating system wireless management utility, in
which case you must use the adapter's management utility.
If the documentation that accompanies the adapter does not
provide enough information to determine if this is the case,
contact that vendor's support group for further advice.
