Wireless Installation Considerations
The  DIR-620S  device lets you access your network using a wireless connection from  virtually 
anywhere within the operating range of your wireless network. Keep in mind, however, that the 
number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass 
through,   may   limit   the   range.   Typical   ranges   vary   depending   on   the   types   of   materials   and 
background   RF   noise   in   your   home   or   office.   To   maximize   your   wireless   range,   follow   the 
guidelines below.
1. Keep the number of walls and ceilings between the  DIR-620S  device and other network 
devices to a minimum – each wall or ceiling can reduce your wireless network range by 3-
90 feet (1-30 meters).
2. Be aware of the direct line between network devices. Place your devices so that the signal 
travels straight through a wall or ceiling (instead of at an angle) for better reception.
3. Building materials make a difference. A solid metal door or aluminum studs may have a 
negative  effect   on  your wireless range.   Try to position   your   router,   access   points,   and 
computers so  that  the  signal  passes  through   drywalls  or   open doorways. Materials  and 
objects such as glass, steel, metal, walls with insulation, water (fish tanks), mirrors, file 
cabinets, brick, and concrete will degrade your wireless signal.
4. Keep your router away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances 
that generate RF noise.
5. If you are using 2.4 GHz cordless phones or X-10 equipment (wireless devices such as 
ceiling fans, lights, and home  security systems), your wireless  connection may degrade 
dramatically or drop completely. Make sure your 2.4 GHz phone base is as far away from 
your wireless devices as possible. Note, that the base transmits a signal even if the phone in 
not in use.
