How do I fix my Toshiba laptop when it says I have no connectivity?
I have a Toshiba laptop that has been going on the internet wirelessly fine. But a few weeks ago, it randomly stopped connecting. the wi-fi switch is turned on, and my other devices such as my home computer and ipod can both connect perfectly. the security settings are also the same. I have been trying to figure it out, and It says I am connected to the router but cant connect to the actual internet beacause my laptop has "limited or no connectivity". Please Help!!!!!!!

If your computer connects to the network through a broadband router , resetting (powering off and on) the router may resolve the issue. If not using a broadband router, or if resetting your router only temporarily resolves the issue and the error message re-appears later, continue to the following steps. If connecting to your network using Wi-Fi and using wireless security, your WEP or other security key may not be set properly. Check the wireless security configuration on your computer's network adapter and update if it necessary. If connecting to your network using an Ethernet cable, your cable may have failed. Temporarily replace your network cable with a new one to determine whether this resolves the issue. If using a broadband router and DHCP on your network, check your computer's IP address to verify it is valid and not a private address that starts with 169.254. An invalid address of the form 169.254.x.x signifies your computer's inability to obtain a usable IP address from your router. To resolve DHCP configuration problems, proceed to the following steps. Reboot your computer, router (if present) and broadband modem together, then re-test your connection. If your connection remains non-functional, run the Windows Network Repair utility on your computer. If your connection remains non-functional, update your router settings to change from dynamic to static IP address configuration, and set an IP address on the computer appropriately. If your connection remains non-functional, unplug your router and connect the computer directly to your broadband modem. If this configuration is functional, contact the manufacturer of your router for additional support. If your computer is connecting to your network directly through a broadband modem, or if your Internet access remains non-functional after following the instructions above, contact your Internet provider for support.

Try to reset your router. Try to disable your wifi adapter and re enable it again. Turn your wifi (laptop) off then on Restart your computer. Uninstall wifi driver then reinstall it again If after trying those things didn;t solve your problem then your wifi adapter is the culprit itself. Bring it to a computer shop and have it replaced.
