8.4 Recovery Procedures
8.4.1 Soft Reset to Factory Defaults
Use this procedure to reset the network configuration values, including the Password, IP Address, and Subnet Mask. This
procedure resets configuration settings, but does not change the current device Image.
• To use this procedure, in the web interface navigate to MANAGEMENT > Reset to Factory.
• The DHCP Server gets the default IP address (169.254.128.132) for the device. You can change the IP address by using
Web Interface or CLI. If you do not have access to the HTTP or CLI interfaces, use Hard Reset to Factory Defaults
(Reload) procedure.
Clients connect at
legacy rates but not
higher rates
• Check the security modes.
– WEP and WPA-TKIP will make the unit to operate at legacy rates.
• Check the Channel bandwidth: Should be set to 40MHz
• Check the Operating mode: It should be either 802.11gn or 802.11an
VLAN Related Issues
Problem Solution
Verifying VLAN
Functionality on the
Device
The correct VLAN configuration can be verified by using ping command in both wired and
wireless hosts from both sides of the device and the network switch. Traffic can be “sniffed”
on the wired (ethernet), if configured. Bridge frames generated by wireless clients and
viewed on one of the backbones should contain IEEE 802.1Q compliant VLAN headers or
tags. The VLAN ID in the headers should correspond to one of the VLAN User IDs configured
for the device.
VLAN Workgroups The correct VLAN assignment can be verified by pinging the device to ensure connectivity, by
pinging the switch to ensure VLAN properties, and by pinging hosts past the switch to
confirm the switch is functional. Ultimately, traffic can be “sniffed” on the ethernet using
third-party packages. Most problems can be avoided by ensuring that 802.1Q compliant
VLAN tags containing the proper VLAN ID have been inserted in the bridged frames. The
VLAN ID in the header should correspond to the user’s assigned network name.
What if network
traffic is being
directed to a
non-existent host?
All sessions are disconnected, traffic is lost, and a Forced Reload is necessary.
• You can configure the switch to mimic the non-existent host.
I have just
configured the
Management ID and
now I can't manage
the device?
Check to ensure your password is correct. If your password is incorrect or all inbound
packets do NOT have the correct tag, then a Forced Reload is necessary.
– Ensure if the Ethernet PC, through which you are managing the AP device, belongs to
the same Management VLAN ID.
: The Forced Reload procedure disconnects all the users and resets all values
to factory defaults.
