What is a 1394 Connection?

by boomerscout / August 22, 2006 11:22 PM PDT

Last week I posted a note about wireless connections and how I had logged onto what I thought might be the local library system's wifi site. I never did solve that problem, but now there is an icon on my bottom bar of two monitors that when I put the cursor over it, a popup appears that reads:

"1394 Connection
Speed: 400 Mbps
Status: Connected"

However, my browser doesn't seem to be running any faster than it did (does) under the AOL dialup. I don't know if I'm actually using the "1394" connection or not, and if not, how do I use it. Any thoughts on this issue? Thanks in advance for any light anyone can shed on this.

It's Firewire. . .

Similiar to USB, just another method of connecting peripherials. How is your modem connected? Have you added any hardware?

No, I haven't added anything recently.

The connection didn't show up until after I logged onto what I thought was the county library's wifi site.

Thanks for the information.

I just opened up my control panel to look and make sure of what I was getting ready to say first. It is a net adapter connection between two computers or it is a router connection to connect two computers. My daughter has a laptop and I have a regular computer. We purchased a router to connect her laptop to my computer so she would be able to access the internet without having to buy or get another modem box from the cable company.

I think that is all it is. You might want to see what other people say about it as well. If you would like to check your computer to see if that connection is active on your computer, go to your control panel and then Internet connections and it should be under that.

Hope this helps in some way!

if you've got firewire, you'll have a 1394 connection. firewire can be used to setup a network link between PCs but rarely is. still windows sees it as a potential network adapter and shows it as "connected" since its working properly. just ignore it.

Thanks. I don't think I have used firewire, but I'm really not sure WHAT it is. As is evident, I'm not knowledgeable on wifi connections.

Evidently, you are using a laptop computer with an internal WiFi adapter. It appears that your laptop's WiFi adapter is connected to your motherboard via an IEEE-1394 (FireWire or I-Link) internal port. The icon in your system tray are indicating that this adapter is now connected and active.

Wikipedia has a full definition of the IEEE-1394 serial bus interface at:

If you are connected to a network via the WiFi adapter then you should notice activity in the icon; otherwise it will just "be there" with no activity. If you have your laptop with you somewhere that you don't know has a WiFi network and you see activity in the icon, this indicates that there is an active WiFi network around you that your laptop is trying or has connected to.

Hope that helps!

Evidentally you like to look at wiki and presume what they write is completely accurate. I have the same 1394 Connection and have NEVER used a laptop! Nor do I use a system with an internal wireless connection. FAIL!

some general info
by ackmondual / August 25, 2006 3:38 AM PDT

Firewire was very common and commonly used on Mac computers until Apple announced they were going to use it anymore on their new comps about a year or 2 ago.

It's also the connection used to hookup camcorders/video cameras to PCs. One way it's preferred over USB 2.0 is it provides FULL power to electronic devices while providing data transfer. USB can also provide power, but the USB port needs to be supplied so, unlike some ports that just transfer data. Even if they do, the PC or laptop may not have enough juice to suffficiently power devices.

should be
''Apple announced they were NOT going to use it anymore''


As for the question.... Checking the motherboard or PC manufacturer's user manual will surely tell you that. Additionally, you could either look online for those specs or call tech support for that. Else, not sure it's possible just from looking it at physically, through one of Windows' screens, or even if there's a utility for this. I'm sure there's a utiltiy, but don't know of any by name.

How do you know if your USB can supply power...
by spiderwaui / February 10, 2007 10:39 AM PST
In reply to: re: some general info

Once you connect your gadget to your PC's USB you will see an icon in the right-bottom of icon tray. The icon say "Safely Remove Hardware.". USB always supply 5 volts of power to any gadget that support it. Some gadget do require more than 5 volts so, you will need an external power source. If you do a "Safely Remove Hardware" process and the icon disappears from the system tray, your PC is not supplying power to your gadget and you can remove your gadget safely.

USB Limitations
by xz4dxx / April 13, 2010 8:32 AM PDT

Only one point missing on the USB Power Supply - the specifications limit the current drain to 500 mA. PER POWERED PORT. This means you can only draw a maximum of 2.5watts of power (5v * 0.5A). If you are using an unpowered USB hub this is spread over all devices connected to the Hub.

This is obvious when you plug a device in to a USB socket to charge it. Either the port overloads or the device never fully charges. Some HTC phones pull 750 mA and some external "USB" disk drives pull 1A. The solution is either an external power supply or using a second USB socket for additional power only.

(NT) This is a 3-4 yearold question.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
