What if the speed LEDs on the VR2/VSI begin to flash?

• Determine if the battery charger is connected to the power base. When the battery charger is connected to the power base, a charger inhibit feature keeps the power chair from driving. This is indicated by the VR2/VSI speed
  LED(s) flashing.
• Determine if the charger harness fuse has blown. A blown charger fuse can cause the charger inhibit to
  activate.
• Determine if all controller connections are plugged into the power base properly. If the 3-pin charger
  inhibit connector is not plugged in properly, then the charger inhibit feature will activate.

Try resetting the Netgear and then configure it again.

To RESET the Netgear, power up the Netgear then press and hold the RESET button at the back of the router until all the LEDs flash. Connect a LAN cable from the Netgear to the LAN port on your computer, open a browser and enter the Netgear configuration URL -
http://192.168.0.1
The default login = admin
The default PW = password You can now change the default admin password and configure the wireless settings.
Go to the wireless configuration and set up the SSID and WPA or WPA2 encryption to protect your wireless network and Internet from unauthorized access.
Now apply these settings to the wireless card in your laptop/computer.

The ethernet switch maybe scanning the ports for connected computers.

I suggest that you factory default the switch in case some security settings or Vlan's/STP have been enabled. Turn off Spanning Tree Protocol (STP) if yiu can access the switch. Check that you ahve no loops in the cabling.

One LED is a Link light that will blink on activity.
The other shows link speed.
These boxes have AutoUplink negotiation so no crossover cables are required.
Test again with a standard straight though ethernet / CAT5 cable.

You probably have to buy another switch. However, before you try that - the eighth most right cable - switch that out to see if it was a cable problem. That's an easy thing to try before you buy another switch.

Hello, Good question..Phone line to DSL modem, Ethernet cable to WAN port on Router. If connecting a PC wired to Router, connect Ethernet cable from 1 of 4 LAN ports on Back of router to ethernet port on PC. This would be Physical connection...
It's always smart to set a restore point in case something goes wrong during installation of any program. For wireless connection from laptop or PC: install router software on computer. Reboot computer. In browser address bar enter 192.168.1.1. This brings up a window for user name and password. Enter "admin" for both. This allows you to change many settings including Changing SSID(Router Name), User name and password. Enabling WEP or WPA security. Hope this Helps, Good Luck..!!

What are the other ends of the cables connected to?
Are the other devices switched on?
Stupid question perhaps, but are any other LEDs on the router on?
Was it all working before or is this a new installation?

Arunk, When you say the electrical characteristics of the new A/C adaptor are the same as the old one did you check to ensure the amperage and the polarity of the power plug is the same as well?
