My computer got a weird problem. I am using broad band provided by my school.
My PC was assigned an IP address automatively by DHCP. When things are right,
the IP address should be 160.***.***.***. However, quite frequently, the IP I
got is 192.***.***.*** and it is not working (I cannot go anywhere on internet
). At the same time, my wife's apple has no problem using the same network (
two outlet from one internet switch). Windows cannot detect any problem with
the connection. Does anybody have

so post ur 192 here
192.168.0.xx
Are you using wireless or wired conncetion via a router?
Probably your laptop picked up a wirelss signal from some other place (which
is not working.) So disable your wireless first.

so ur network structure is: the switch connects to the internet port, and u
r connecting computers through the switch?
If this is correct, the problem may be: that internet port can only assign
one ip; so if you need to connect more than one computers at the same time, u
need a router instead of a switch.

A switch. But I don't think that is the reason because the same thing happens
even I connect my computer directly through the internet port without using a
switch.

You are right about my network structure but I don't think that is the reason
because the weird IP thing only happens once a week no matter how many
computers are linked to the switch. I tried linking my PC to the internet port
directly when the weird thing happens and it did not solve the problem.

I cannot set a static IP by my own without authorization from my school. It is
going to conflict with others unless I never turn off my computer.
