I can't log in. It keeps saying "There may be a problem with your internt connection or SL Grid!

Are you using one of your school computers? Then Second Life may very well be blocked by a firewall. It would only be normal that a school/university doesn't allow any program to run on their machines. You may want to discuss that with the tech person in charge where you study.

Quoting Rolig Loon:

 

Just because you can use a web browser and get e-mail, don't assume that your Internet connection is "working well."  It's just working well for those simple things.  SL demands a much more stable, strong connection than those things do.  The first suspect is the sim where you have tried to log on, so make sure to choose a quiet region such as Smith, if you still can't log in, it has to be your connection.  So, begin with the easy things: (1) Don't Use WIRELESS. Wireless connections are inherently less stable than direct cable connections and are more vulnerable to interference. Then, (2) Reboot your router. Unplug it from the power for a few minutes to let it clear its RAM. Then plug it back in and let it get a fresh hold on an IP address.  If those don't work either, see Nalates' blog for some other suggestions >>> http://blog.nalates.net/2011/10/26/troubleshoot-your-sl-connection/

Hello,

are you sitting behind a proxy? You have to enter the proxy settings in the viewer under Me->Preferences -> Network.

Best way to find out your proxy settings is to check the proxy settings in your webbrowser.

It would help to know what you and the computer tech have tried.

Have you worked through the remedies suggested in the articles on Login Failure and Using Second Life with a firewall,  particularly the section on Using Second Life from a closed network?

Second Life is a complex, graphic intense software which basically requires a computer that can catch up with todays games. Also you will need an internetconection that could also handle other online games or live video streams.

This means an office computer, used for email and simple programs, won't work well with Second Life.
