Connecting Netbook on to schools network.

September 27, 2011 at 11:57:34
Specs: Windows 7
My daughter has recently got a Levnovo netbook for use at home and school. We have allocated a fixed ip address at home for safety using wireless. But she cannot connect to the wireless network at school without changing the netbook each day to turn DHCP back on. Can you help? The school says I have done something wrong?

Thanks

I'm a little confused as to what safety you think there is in assigning a fixed IP address. What is the reason for this?

The instructions I see to number of the issues around networking on this forum as regards wireless and I quote from a thread related to the issue "For small networks like a home network, you can add some extra protection by turning off the DHCP, or automatic IP addressing, feature of the router and manually assigning static IP addresses. "
I do not intend to turn off static ip addresssing on my home network as it has been very reliable and robust for me.

I "For small networks like a home network, you can add some extra protection by turning off the DHCP, or automatic IP addressing, feature of the router and manually assigning static IP addresses. "

Whoever wrote that was talking rubbish. It will do absolutely nothing at all for security. Not the slightest.

If you must have static addressing at home and DHCP at school then you can set up different profiles. You daughter will then be prompted for which profile to use every time she boots. I dont know how you do that in Windows 7 but in Windows XP it comes under system properties.

Thanks for the reply, I especially like "whoever wrote that was talking rubbish."

I like the idea of a different profile, sounds like it could work, I will have a look,

Thanks

I suppose that it could conceivably be argued that not using DHCP makes it marginally harder for someone to gain access to your wireless network (although that would be a pretty poor argument IMO), so there is a very, very small grain of truth in what you have read. But it's really not that difficult for anyone with any knowledge to work out what IP address range your router is using and set their computer to use a static address in that range.

The real answer to securing your wireless connection is to use encryption (WPA if you want it to be effective) and to switch on the MAC filtering option on your router which allows only network devices that you have authorized to connect to the router. These two measures make it much more difficult for a potential attacker.

Thanks for everyones help. I have found and installed a little program called mobilenetswitch. This alters the ip addressing system whenever I logon to either home with fixed ip or school using dhcp .
