Only connecting to PSN every other day...?

[Snorevette]

On Saturday my PS3 simply refused to connect to the internet even after I tried everything.
On Sunday I had no issues.
On Monday the problem started again.
Yesterday I could connect again.
Today I have the same problem...?

Does anybody have any idea about what is going on here?

Try to check your modem, the problem can be your internet.
