What is "limited or no connectivity" mesage mean when accessing a home wireless network?

I have a TW cable modem with a Linksys wireless router; frequently I get a message that indicates the signal strength is "excellent" but I cannot get online and the "limited or no connectivity" message appears in the wireless desktop application dialog. I can get on via a neighbor's unsecured network, but not my home network. what can I do?

1. there may be an outage in the area
2. Most often the problem with having a flaky network connection, even though the signal strength is "excellent", is because your wireless network is operating on the same channel as another nearby network, and the two are interfering with each other. On most devices, the default channel is 6, so that channel is frequently filled by neighbors who don't know enough to change the default setting. Despite what the other Answerers on here have indicated, Limited or No Connectivity has absolutely nothing to do with the wireless signal. You can get the same message on any hardwired network connection - it just means that your network connection is unable to initialize certain setup requirements, like negotiating with the other devices on the network and getting an address. Log in to your router and change the channel (should be under basic or wireless settings) to something at either end of the spectrum - 1, 2, 10 or 11 and see if that improves it.
3. that means that the conecction is weak, you can call your wireless network and ask for assistance, tahts what i did.
4. I had this problem with Belkin and had to call the company and get them to walk me through resetting my entire setup. After that, it fixed the problem. There was something wrong in my settings. Prepare to devote about an hour to fixing this, but it is really worth it not to have this problem. It's VERY aggravating.
5. your modem might be defective.
6. Maybe the router has settings blocking you out. Maybe the router is set to a lower power than your neighbors, the higher the power setting, the wider the frequency. Limited or no connectivity means your too far away to pick up a good signal.
7. i thing that mayeb ur ip or other information is wrong.....check that...rite clik on ur network icon in the taskbar..>status>properties>internet protocol(TCP\IP)>properties and then check ur ip info....ask ur service provider for ur exact IP and other info........
8. The problem is that although your wireless card is connecting to the router it is not getting an IP address from the router. This is probably because you have likely not entered the password required by your router on your wireless card during set up of the card .. fix that and it should solve the problem..
