Reduce interference in a wireless network
The following tips will help reduce the chances for interference in a wireless network:
●
Keep the wireless devices away from large metal objects, such as filing cabinets,
and other electromagnetic devices, such as microwaves and cordless telephones,
as these objects can disrupt radio signals.
●
Keep the wireless devices away from large masonry structures and other building
structures as these objects can absorb radio waves and lower signal strength.
●
For an infrastructure network, position the WAP in a central location in line of sight
with the wireless devices on the network.
●
Keep all wireless devices on the network within range of one another.
A personal software firewall is blocking communication between the printer and
the computer
The personal software firewall is a security program that protects a computer from
intrusion. However, the personal firewall might block communication between the
computer and the printer.
If you cannot communicate with the printer, try disabling the personal firewall. If you are
still unable to communicate with the printer, then re-enable the firewall.
If disabling the firewall allows you to communicate with the printer, you might want to
assign the printer a static IP address and then re-enable the firewall. To assign the printer
a static IP address, see the Setup guide that came with the printer.
The wireless access point filters MAC addresses
MAC filtering is a security feature in which a
is configured
(also called "hardware addresses") of devices that are
allowed to gain access to the network through the WAP.
If the WAP does not have the hardware address of a device attempting to access the
network, the WAP denies the device access to the network.
If the WAP filters MAC addresses, then the printer's MAC address must be added to the
WAP's list of accepted MAC addresses.
