Wireless Range
Range should not be a problem in most homes or small offices. If you experience low or no signal
strength in some areas, consider positioning the Router in a location between the WLAN devices
that maintains a roughly equal straight-line distance to all devices that need to access the Router
through the wireless interface.
SSID
Wireless networks use an SSID (Service Set Identifier) to allow wireless devices to roam within the
range of the network. Wireless devices that wish to communicate with each other must use the same
SSID. Several access points can be set up using the same SSID so that wireless stations can move
from one location to another without losing connection to the wireless network. The M505N
operates in Infrastructure mode. It controls network access on the wireless interface in its broadcast
area. It will allow access to the wireless network to devices using the correct SSID after a
negotiation process takes place.
By default the M505N broadcasts its SSID so that any wireless station in range can learn the SSID
and ask permission to associate with it. Many wireless adapters are able to survey or scan the
wireless environment for access points. An access point in Infrastructure mode allows wireless
devices to survey that network and select an access point with which to associate. You may disable
SSID broadcasting in the web manager’s wireless menu.
Radio channels
The 802.11b/g/n standard allows several WLAN networks using different radio channels to be
co-located. The M505N supports multiple radio channels and is able to select the best radio channel
at each startup. You can choose to set the channels automatically or manually.
The different channels overlap. To avoid interference with another access point, make sure that the
separation (in terms of frequency) is as high as possible. It is recommended to keep at least 3
channels between 2 different access points.
The M505N supports all channels allowed for wireless networking. However, depending on local
regulations, the number of channels actually allowed to be used may be additionally restricted, as
shown in the table below.
