Well, thanks for all the information!
But i've 'managed' to fix the problem.
My hub is broken, but very strange, 'cause i've a few linux/windows pc's on that hub, and those pc's work well.
Anyway, i did put the solaris straight into the router, and the problem was fixed.
Very strange, but it did help
.
Now i'm installing alot of things..
Cheers
