Internet connection guidelines
In order to achieve the best performance of your iTero scanner, ensure that the internet connection upload speed
is at least 1Mbps per scanner. Also, note that any additional devices connected to the internet in parallel to the
scanner may affect the scanner’s performance.

Firewall
Open the following port (in case of a firewall):

Wi-Fi tips
Wi-Fi routers allow you to access the internet system using a Wi-Fi connection from essentially any place within
the functional range of the wireless network. Nevertheless, the number, depth, and position of walls, ceilings, or
additional partitions that the wireless signals must travel through may limit the range and strength of the signal.
Normal signals vary, depending on the material types and background RF (radio frequency) noise in your home or
business.
l
Be sure to have a minimal number of walls and ceilings between the router and other network devices. Each
barrier can reduce the adapter’s range by 1-3 meters (3-9 feet).
l
Be sure to have a straight line, free of any partition, between network devices. Even a wall that seems rather thin
can block a signal of 1 meter (3 feet) if the wall angle is shifted by only 2 degrees. To achieve the best reception,
place all the devices so that the Wi-Fi signal travels straight through a wall or partition (instead of at an angle).
l
Construction materials make a difference. A solid metal door, or aluminum nails, can be very dense and may
have an adverse effect on a Wi-Fi signal. Try to position access points, wireless routers, and computers so that
the signal travels through drywalls or open doorways. Materials and objects such as glass, steel, metal, walls
with insulation, water tanks (aquariums), mirrors, file cabinets, brick, and concrete may reduce the wireless
signal.
l
Keep the scanner away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF
noise.
l
If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, remote lights, and
home security systems), the wireless connection may be severely degraded or entirely drop. The base of many
wireless devices transmits an RF signal, even if the device is not in use. Position any other wireless devices as
far as possible from the scanner and router.
l
In your area, there may be more than one active wireless network. Each network uses one or more channels. If
the channel is near your system channels, the communication may gradually decline. Ask your IT department to
check this, and if required, change the channel numbers used by your network.
