Solution
Make sure your computer or network device are turned
on. Also make sure that you can access the internet and
other devices on the same network from the devices you
are trying to connect to your product.
If you still cannot connect to your product, turn off your
router or access point, wait about 10 seconds, and turn it
on again. Download and install your product software
again to reset your network settings.
Make sure other devices on the network are turned on and
do the following:
• If your product's Obtain IP Address setting is set to
Manual, check the IP address, subnet mask, and
default gateway addresses on the network connection
report to see if they are correct. If not, correct the
settings.
• If DHCP is enabled, set your product's Obtain IP
Address setting to Auto. If you want to use the DHCP-
assigned address as a static address, set the Obtain IP
Address setting to Manual, enter the product's IP
address as listed on the network connection report, and
set the subnet mask to 255.255.255.0.
If you still cannot connect to your product, turn off your
router or access point, wait about 10 seconds, and turn it
on again.
If you set your product's TCP/IP Setup setting to Manual,
check that the default gateway address listed on the
network connection report is correct. Also turn on the
device that is set as the default gateway.
