Troubleshooting

The target access 
point is not detected

If the machine or your computer cannot communicate with the target 
access point, follow the procedure below.

1 Ensure that the access point is on and then click [Update] in the 

[Access Points] dialog box.

2 If the access point is still not detected, move your machine closer 

to the access point and remove possible obstructions, then click 
[Update].

3 Ensure that your computer can communicate with the access point.

For details, see “Checking if the computer and the machine (access 
point) can communicate with each other” in the Network Guide.
4 Unplug the access point from the power outlet and plug it in, then 

click [Update].

z Using your access point’s utility software, check if your access point 

is set to the stealth mode, i.e., set not to broadcast its SSID, or is set 
to reject clients whose SSID is set to ANY. If so, click [Manual Setup] 
and enter the access point’s SSID in [SSID]. For details, see 

“The 

[Access Points] dialog box is displayed during setup” on page 61

.

z The wireless channel to be used may be limited depending on 

wireless network devices installed in the computer. Confirm the 
wireless channels available for the network device. For details, refer 
to the manual provided with your computer or your wireless network 
device.
Make sure that the channel set to the access point is valid to 
communicate with the computer, confirmed above. If not, change 
the channel set to the access point.

z Some access points are capable of automatically switching between 

wireless channels. This machine may not be able to connect an 
access point if its channel is set to automatic or the equivalent, or to 
a channel outside of the range 1 to 11. Configure the access point to 
use any channel between 1 and 11.

z Make sure that there is no barrier or obstacle between the access 

point and the machine.

Cannot connect to the 
target access point 

z Confirm the network name/SSID of the target access point and set the 

machine to use the identical network name/SSID. If the network name/
SSID is different in the machine and the access point, the machine 
cannot connect to the access point. For details, see 

“The [Access Points] 

dialog box is displayed during setup” on page 61

.

This machine does not support WPA-Enterprise or WPA2-Enterprise. 
When you select an access point set to use WPA-Enterprise or WPA2-
Enterprise, it is grayed out and cannot be set up.

z Make sure that the machine and the access point can communicate with 

each other under this setting. When encryption is set to the access point, 
set up the encryption of the machine to match the settings of the access 
point. If the WEP/WPA/WPA2 (encryption key) is different in the machine 
and the access point, the machine cannot communicate with the access 
point. For details, see 

“How to set a WEP/WPA key” on page 59
