Wireless Router limited or no connectivity issue

I have a netgear wireless router that is working when I got one pc wired to it.
When I put in a usb wireless fob into a pc , the tray icon detects the netgear router, so I enter my password and got connected.

Now the other tray Icon ( the little pc monitor with the wireless signal) connects but says limited or no connectivity.

I've tried uninstalling everything, also re-entered the IP address , but still it I doesnt see any wireless connectivity?

Try to connect netgear wireless router WGR614 to dataone broadband router MT841 router within the BSNL broadband forums, part of the DSL Broadband Service Providers category......Check if it supports

First check the router settings if you have you logged.
Usually you will find an address like 192.168.0.x. Look up your router and log into it and make sure that DHCP is turned on.
If DHCP is turned off then it is acting like an access point and only the wired computer will get an ip address.

Maybe because the DHCP server on your Netgear router doesn't have enough IP adresses available?
Check the configuration of the router.

Try renaming your pc and see if this helps and increase the range of IP addresses the DHCP server in your router can allocate.
