Network no longer available. WLAN not working now?

I keep receiving this message from my phone when I try to connect to my home network. My situation may be different from yours, so there is no suresafe way to recover from this bad problem.

1. Is your phone software the latest?

My previous version was 04.4.5 RM-614 , 04-08-10. Yu can check yours by selecting Settings/Phone/Phone Updates from the Main Menu.
Now it outputs

V0 8.70.

If you have not done so, install the latest Nokia-Suite on your Windows OS. Google for Nokia_Suite_webinstaller.ALL. The current version is at 3.848.

After installing the Nokia Suite software, first be sure to full charge your phone! Attach a microusb cable to phone and computer. Then from Nokia Suite, select Tools/Software updates. The updating may take a lot of time as it will try to save or backup your messages, photos, contacts etc. then will update your phone software.

AVOID turning off or on your phone during this process and ignore any Windows warning about disconnection of phone. Your phone screen may go blank during this process more than once. Be patient, it may take more than 30 minutes for the whole backup and software updating process.

After Nokia_suite tells you it has finished, then it is SAFE to remove the USB cable from phone and computer. Turn on your phone
and it will feel perceptably faster. However I still get Network no longer available when trying to connect to the WLAN. Do not get mad at this stage.


:) Thank the Lord I still have an Android phone.
