Network link is down
Since the Spectralink handsets do not have an LED indicating network LINK status like many
networking devices, link failures are indicated with a message.
The ‘Network link is down’ message will be shown on the screen whenever the handset is not in
the menu system and will persist until the link problem is resolved. Call related functions and the
softkeys and line keys are disabled when the network is down; however the menu system
works.
Check the top left corner of the 84-Series display to determine if the AP signal strength bars
have a red X across them.
If there is a red X, the handset is not connected to an AP.
Has the handset connected to the WLAN before or is this the first failure of this kind? Is the AP
operational?
Ensure the handset is configured properly for the WLAN (SSID, security, RF radio and
channels,
If there is no red X then the handset has connected to an AP.
This means the handset and AP agree for SSID, wireless security, RF radio and channels, etc.
Does the handset have an IP address?
If DHCP is enabled then it must supply an IP address to the handset.
If DHCP is disabled, then the handset will have a static IP address assigned.
Check handset for an IP address at
Settings> Status> Network> TCPIP Parameters
Can it ping the boot server, SIP server or another 84-Series handset?
The Ping function is at:
Settings> Status> Diagnostics> Network> Ping
. Enter IP address
and press Start.
Did the handset download configuration files when it booted?
Check
Settings> Status> Platform> Configuration
scroll down to see file names and
parameters loaded from each one
