What is the Error Code?

Usual causes of Internet Disconnection:
1. System is Cluttered by junk files, cache files and other unnecessary files.
2. More client-applications installed that needs server connection
3. Block by your own firewall application


Resolution:
1. Clear History Files, Cache Files, Cookies and Junk Files. You can use CCleaner Application or Advanced SystemCare Application for Mobile to clear History Files, Cache Files, Cookies and Junk Files and even optimize your mobile performance.

2. Temporarily remove client-applications installed that needs server connection.

3. Disable your own Firewall Application temporarily

4. Refresh Network connection by Disabling and Enabling it.
5. If you are connected to a Router, restart your Router if not, reset it.

These might help you.

If you have a combination modem/wireless router you should be able to connect your tablet to the internet. If not, you will need to either buy a wireless router that connects to your modem to broadcast the wireless signal or contact your service provider and get the combination modem/wireless router.

You have to re-connect wifi network within the phone. Go to system settings -> wifi -> choose your new SSID and type in passphrase.

Do other wireless laptops connect to your wireless router, and give good speeds? Do you have many wireless networks, other than your own, that show up when you try to connect? It could be interference from other wireless networks in your vicinity.

change the security type of router to WEP and password accordingly.
Now disconnect the samsung galaxy phone from internet and try to connect it back with new password. you will be able to access the internet.
It is resolved.

Lexmark just recently released the Lexmark Mobile Printing Application for use with Android devices, however, the application is supported only on most laser products and the very latest inkjets that are coming out for 2011(the Lexmark Pro715 and the Pro915 are the only models announced at this point.).

Try resetting the Internet sett on tab and connect again
