52 CHAPTER 4: TROUBLESHOOTING
Symptom Solution(s)
After you change the IP
address, after you restore a
backup configuration, or after
you reset the Ethernet
Adapter to factory defaults,
the Configuration
Management System stops
responding and you cannot
continue configuring the
Ethernet Adapter.
If you change the IP address and click Apply, you
cannot continue to configure the device using the old
IP address. Similarly, after you restore a backup
configuration or reset the Ethernet Adapter to factory
defaults, the IP address setting may be changed.
To recover from this situation and continue configuring
the Ethernet Adapter:
1 Close your browser.
2 Return to the Enterasys Networks Wireless
Infrastructure Device Manager and click Refresh.
3 Select the device and click Configure to start a new
configuration session and set its IP address.
The Ethernet Adapter cannot
associate with an access point.
■ Adjust the position of the Ethernet Adapter to
improve reception.
■ Launch the Ethernet Adapter Configuration
Management System and make sure the security
settings on the Ethernet Adapter match those on
the access point.
The Wireless Network Tree does
not appear in the Enterasys
Networks Wireless Infrastructure
Device Manager window.
Verify that you are using the correct network adapter.
In the device manager window, click Choose NIC.
Select the network adapter for the network you want
to scan, and click OK.
The Ethernet Adapter has a
yellow exclamation point (!)
next to it in the Wireless
Infrastructure Device
Manager.
The Ethernet Adapter is on a different subnet than the
computer attempting to configure it.
To recover from this situation and continue configuring
the Ethernet Adapter:
1 Close your browser.
2 Return to the Enterasys Networks Wireless
Infrastructure Device Manager and click Refresh.
3 Select the device and click Configure to start a new
configuration session.
4 Make sure the subnet address matches that of the
computer.
Two Ethernet Adapters cannot
communicate in ad-hoc mode.
■ Adjust the positions of the Ethernet Adapters to improve
reception.
■ To ensure correct operation in ad-hoc mode, the
settings on the two Ethernet Adapters must match
exactly. Launch the Ethernet Adapter Configuration
Management System and make sure that the
Wireless LAN Service Area, channel selections, Data
Preamble setting, and security setting are the same
on both Ethernet Adapters.
