I always get a bit confused when configuring or setting up a LAN on XP. Maybe on win7, too.
There's the wireless network. That's a Lan, surely?
The wireless network is a LAN, and is considered by many users as a Wireless LAN because it runs the same way as the standard LAN, only wireless.
To be honest, in this year its kinda pointless to setup a LAN manually through XP as the method is a lot more difficult then what Windows 7 has now. I don't see a purpose to setup a LAN on my machines, as they all run Windows 7 and higher, I can simply setup a Homegroup, which links all the computers to one network and provides options for what you would like to share
My confusion arises because there's apparently two LANs but the computer never talks about this, never puts it that way.
And there's the Microsoft Lan that I might be trying to set up. More often I'm having problems with it and keep getting directed to Lan setup pages via control panel.
Like just today I couldn't access the workgroup and I kept getting to pages wanting me to create a lan or join a lan or configure a lan or something.
To answer these points as best as I can. Windows XP only had early wireless support at the time if I'm not mistaken (in fact, I think it was the first OS to intergrate full wireless networking support without 3rd party software, which would have had to be used in 98/98SE/2000 .etc), and many computers who had previously upgraded only used LAN and/or Dial Up. Wireless networking didn't really have much of a part in the networking world then as it does now. My old Packard Bell EasyNote R1004 laptop from years ago (I still have it), around late 2005 to early 2006 was running the internet through the phone line, although it had a wifi card for wireless networking alongside standard LAN, but the wifi was not used until later in the year when we got our first Internet Service Provider.
I don't know what you mean about Microsoft LAN, as I've never heard of it. If you want to set up a LAN network, its best to run a ethernet cable from a router into the computer and that usually works out the box. The only time I would have thought you would need to use the LAN setup is if you needed to connect to a business network and have full access to services such as server storage.
Don't get me wrong, I use Workgroups on all of my household's computers by giving them the same name. I don't really notice anything different unless I use Homegroup so its probably harder to use and most likely obsolete. If you are getting to pages to create a LAN network, join a LAN network or configure a LAN network, then you may have incorrectly configured your network settings.
All of what I said is my theory, not fact. The way it may work may be different to what I've said above, but either way, I hope it helps
