[Need help with this tech problem]

Hi everyone i really need help with this cause i cant figure it out alone.

Here is my issue.  Last friday my internet company changed my modem cause the internet connection was slow and the modem was old.

I got a new modem now internet fly but i cant log in to sl again! When i try appears a sign that says there is a connection problem. Of course i re started de modem but i still cant log in. Im connected with pc at cable. I tryed notebook on wifi and got same problem.

Called internet company, service people came and didnt found any problem on connection. They say is sl problem.

i can connect to any website, and pc works well. I could log in 3 times for few moments today (wich is the stranger thing) when i was testing connection,  but when i log off and try again i cant pass the "connecting to region" phase on Firestorm. I try sl viewer and same thing.

I even try to log in in other virtuals worlds, like Metropolis metaversum, and everything works perfect. The only site i cant connect is sl. I made such a good friends around the world here whom i connect weekly and i really dont want to leave sl, but i cant figure this out and is very frustrating. Plus im not a computer expert so everything is more complicated.

If you have any idea how could i solve this problem i would be very grateful. Ty for reading.

Marian.
