Cisco Aironet AP PoE Injector Issues – Radios Disabled

Cisco Aironet AP’s disabled due to insufficient power

Cisco Aironet - PoE injector issues

Cisco Aironet AP’s were disabled due to insufficient power (problem with power negotiation from the PoE injector). System Power Settings (web interface) displayed a LOW_POWER_CLASSIC_NO_INJECTOR_CONFIGURED message. I accessed the console and issued ‘power inline negotation injector installed‘ but was told to verify that the required power injector was installed on a particular port.
“This condition occurs when the access point is powered from a power injector but is connected to a switch that supports CDP but cannot provide the full 15.4-W Power over Ethernet (PoE).” (network.allfaq.org)
Disabling CDP on the AP immediately resolved the issue:
no cdp run
Web Interface now displays:
Power State: FULL POWER
Power Source: NON_CISCO-NO_CDP_RECEIVED

Vista Wireless Adaptor Issues

Vista Wireless sucks. I’ve had intermittent wireless connectivity issues on my laptop (which now dual boots Ubuntu 9.04), and now I have friends and family complaining about the same problem.
Microsoft blames the DHCP BROADCAST flag, which was disabled in XP SP2, but is NOT disabled in Vista. Here is the M$ support KB entry, and here is a post with the regedit steps including screenshots.

Notes: Client’s router is a netgear WGR614v6 (firmware: V1.0.11_1.0.7NA), if this is really the issue, then setting a static IP should resolve the problem. Let’s try that and see if it helps… Also, the latest firmware for that router is 2.0.19_1.0.19, which I downloaded in case we want to try that next. Download and instructions can be found at kb.netgear.com

Update: Setting a static IP seems to have improved the situation, but not resolved it entirely. Now the issue appears only when coming out of sleep mode. A post by “Deke” on arstechnica.com explains:

I had this issue on my desktop after it returns from an S3 sleep state. You can do one of two things.

1. You can simply open an elevated command prompt and type ipconfig /renew each time,

or

2. You can automate the the above process:

Make a small batch file with a single line: ipconfig /renew

Put it in a folder somewhere (I used c:windowssystem32).

Open the task scheduler and create a new task. Make sure that you check “Run with highest privileges.”

Trigger should be set to “On workstation unlock of any user”.

Action is “Start a program”. Point it you your batch file.

Under the Conditions tab, make sure “Start the task only if the computer is on AC power” and “Stop if the computer switches to battery power” are both unchecked.

Lets give that go…
