Internet problems

[Ray M]

Since I installed 10.2.5 I noticed some problems occurring with entourage
when I want to check my mail!

When the computer goes to sleep I have to restart it to be able to check my
mail!
My computer would connect to my isp but I'm unable to browse the net and
unable to connect to my smtp. Logging out then in won't resolve the problem
only a restart would do.
Does anyone has had the same problem?
Any solution?

Thanx
ray
