Wireless network setup 

•  

Check whether firewall software (V3 or Norton) is blocking the 
communication. 

If the computer and the machine are connected on the same network and it 
cannot be found when searching, firewall software might be blocking the 
communication. Refer to the user's guide for the software to turn it off and 
try searching for the machine again. 

•  

Check whether the machine's IP address is allocated correctly. You can 
check the IP address by printing the network configuration report. 

•  

Check whether the access point (or wireless router) has a configured 
security (password). If it has a password, refer to the access point (or wireless 
router) administrator. 

•  

Check the machine's IP address. Reinstall the machine driver and change the 
settings to connect to the machine on the network. Due to the 
characteristics of DHCP, the allocated IP address could change if the 
machine is not used for a long time or if the access point has been reset. 

Register the product's MAC address when you confogure the DHCP server 
on the access point (or wireless router). Then you can always use the IP 
address that is set with the MAC address. You can identify the Mac address 
of your machine by printing a network configuration report. 

•  

Check the wireless environment. You might not be able to connect to the 
network in the infrastructure environment where you need to type in a 
user's information before connecting to the access point (or wireless router). 

•  

This machine only supports IEEE 802.11 b/g/n and Wi-Fi. Other wireless 
communication types (e.g., Bluetooth) are not supported. 

•  

When using the ad hoc mode, in operating systems such as Windows Vista, 
you might need to set the wireless connection setting every time you use 
the wireless machine. 

•  

You cannot use infrastructure mode and ad hoc mode at the same time for 
Dell wireless network machines. 

•  

The machine is within the range of the wireless network. 

•  

The machine is located away from obstacles that could block the wireless 
signal. 

Remove any large metal objects between the access point (or wireless
router) and the machine. 

Make sure the machine and wireless access point (or wireless router) are not 
separated by poles, walls, or support columns containing metal or concrete. 

•  

The machine is located away from other electronic devices that may 
interfere with the wireless signal. 

Many devices can interfere with the wireless signal, including a microwave
oven and some Bluetooth devices. 

•  

Whenever the configuration of your access point (or wireless router) 
changes, you must do the product's wireless network setup again. 

•  

If Wi-Fi Direct is ON, this machine only supports IEEE 802.11 b/g. 

•  

If the access point is set to work with the 802.11n standard only, it may 
notconnect to your machine.
