I upgraded my wireless home network this weekend from an old Netgear 802.11b router to a shiny new Linksys WRT120N router sporting the latest 802.11n technology, and a much sleeker design.

The network speed difference is very noticeable and significantly faster on the newer router, and the units were on sale for only $39 at Fry's so it seemed like a steal of a deal... until I tried to install it.

I have Comcast internet at home with a standard-issue Motorola cable modem, and it turns out that Linksys routers don't naturally connect directly with these modems.

The Network Magic software that comes with Linksys routers failed on the first setup screen with an "Error 321", claiming it could not detect my ethernet network adapter. Apparently the Linksys routers require you to connect through a separate router that sits between the Comcast modem and the Linksys router (or at least that's what I found hidden somewhere in the documentation) - and in fact, it worked fine if I connected through my old Netgear router to the Comcast modem.

I was also able to connect directly from my computer to the Linksys router, which I was able to verify by running ipconfig and seeing the IP address assigned by the router. I was also able to log into the router's admin console screens by opening a web browser and entering the IP address of the router - http://192.168.1.1 using admin/admin for the username/password.

Question: My dell 8400 tower went down, replaced power supply and ..nothing. How can I get everything off the hard drive, install into another tower, or take it somewhere to download to external drive?

Answer: From what you've described, it sounds like your motherboard is probably fried. Since the Dell 8400 series run an old Pentium 4 processor, it's probably not worth bothering with trying to replace the motherboard and you're better off trying to get the data off the hard drive and replace the system altogether.

You have a couple options for doing this. You can hook up the hard drive as a slave drive in your new system, or you can use an IDE adapter that plugs into a USB port and treats your hard drive like an external USB drive.

Either way you'll need to remove the hard drive from your old system, which is easy to do. Remove the screws from the outer casing (some cases let you slide the side off without removing screws) and locate the hard drive. There will be a flat thin cable about 2 inches wide connecting it to the motherboard. Remove the screws holding the hard drive to your case (usually 2 on each side) and then remove all cables and power cords going into the hard drive.

IDE Adapter

The easiest way to get data from your old hard drive onto another desktop system or laptop is to connect it using an IDE adapter. The adapter will connect your hard drive with your other system's USB port, and will let you copy files over just like it was a USB flash drive.

Question: Suppose we have a networking in a LAB and i have total rights over all other systems on the LAN. Now how to change the wallpaper of the system which is there on the LAN???

Question: I have a computer with a 20GB drive and would like to install a 80GB drive that I have, as the 20GB drive has under 1GB remaining. Can I use imagining software to copy all Programs, files, and folders (including system files) from the old drive to this bigger drive, and make it be the startup drive? What would be the best software for me to use?

Answer: Yes, you can copy the contents of one hard drive to another, as long as the drive you're copying to is as large or larger than the old drive, and as long as you have the right software. You can even copy installed programs and the operating system over to the new drive, so you don't need to spend money on another Windows license or worry about re-installing programs.

Both hard drives will need to be connected to your motherboard using a standard IDE cable. Two hard drives can be connected with the same IDE cable - just make sure that the old drive (master) is connected to the first available connector slot, and the new drive (slave) is connected to the middle slot on the cable.

You'll need a software program to copy over the old hard drive's contents to the new hard drive, also known as "ghosting" or "disk imaging".

I'll discuss 2 disk imaging programs in this article - one that's both a ghosting program and a backup program, and another lighter-weight solution that only handles disk copying (and is more affordable too).

Norton Ghost

Norton Ghost is a well known and trusted program that will duplicate your old drive directly to another drive.

Norton's step-by-step wizards make it easy to copy the contents of your old drive to your new hard drive, even if you're not super technical or very good with computers.

I'm heading to Chicago tomorrow morning for another business trip, and really needed a way to stay connected with my family while I'm away.

Video chat sounded promising, and since my wife's laptop has a built-in web cam and I have a high quality web cam that clips onto my work laptop - I figured this might just be the solution.

With our laptops side-by-side, I tried AIM, Skype, and Sightspeed.

I wasn't able to get AIM or Skype working with my laptop's web cam, which is a 2 megapixel Creative Optia. It sits on top of my laptop and plugs into a usb port, and has a high quality auto-focus feature that makes video images look noticably better than standard 1.3 megapixel webcams.

I installed a free copy of Sightspeed on both computers and created accounts for my wife and myself. I wanted to make sure the software worked with our different webcams and computers before getting halfway across the nation.

Sightspeed lets you make video calls over the Internet so you can hear and see the person on the other end of the call.

Creating an account and downloading/installing the software only took about 2 minutes for each computer, and it automatically detected the microphones and web cams on each of our computers.

Starting a video chat was as simple as adding a contact and clicking the Start Video button next to the contact's account name in Sightspeed.
