Windows 7: Network problems

Hi,
I am having too many problems in Network with Windows 7.
I had not these problems in XP, I believe.
For example, when a connection is being made, I cannot click on Network icon on task bar and many times that connection hangs and I have to restart.
Many times I cannot connect until I restart.
Anyone has the same problem?
Thanks.

Please fill out your system specs (see the link in my signature).

Also, please run an administrative ipconfig /all

Start > Search For "cmd" > Right Click cmd.exe > Run as Administrator > Type "ipconfig /all"

Have you tried updating your network card drivers?

If you would like answers that are anything but guesswork, we're going to need a lot more detail than this.... Adaptor settings, software in use, network settings etc.

Well, my network adapter is a Broadcom 400x 100/1000 integrated controller (I'm using a Dell Inspiron laptop).
There are no drivers for this card for Windows 7 x64 but the ones Windows installs itself (driver version: 4.60.0.1)
I use an Asus AM602 ADSL modem to connect to the Internet, I think I have to get used to this fact that Network Connections was better is XP.
At least here when a connection is being made you cannot open any other connection or click on Network Connections from taskbar, and the worst thing is that if connection goes time out, you cannot cancel it, even cancellation will cause it to get busy in the background...
