why do you need to have wifi on a laptop computer
1433508
If you don't want to have your computer physically connected by wire to an internet connection, and you want to go on the Internet, you need wifi. That way you can use your computer and get on internet everywhere there is wifi. Doesn't make sense any more to get a laptop without wifi. Hope this clarifies.

It allows a wired connection anywhere it is plugged in. If plugged in to an Airport Express, then the Express would be an extended new WiFi connection. If plugged in the a portable laptop, then it would a much faster connection than a wireless connection expanding the existing network. So the answer to your question is that it can be both depending on what you connect to it.

Yes, provided you have your original wifi network on and feeding it. It just expands the range of your existing network. No computers need to be on.

No, you will need to add a wifi card to your computer. This will simply extend the range if your network connection. You need to get a network connection first. Check to make sure your wifi isn't turned off on your computer most computers built in the last five years org so have wifi capabilities. Your owners manual may help as well.

If your router has wireless capabilities, you need nothing else, unless you have a system laptop or desktop that does not have wireless software/hardware that allows it to search for the wireless signal from your router.

If your question is, do you need one? The answer is no, but you can use one to update firmware, and connect to all of the features that are available when you connect it to the internet (featured on the page). I've used these features rather infrequently, and therefore only plug it in occasionally. There isn't a "wifi" feature built in if that was your question also. Hope this helped!

It only needs to be plugged in to a computer during set up. After that it can be disconnected from the computer and moved to wherever it provides the best improvement in signal strength from your router.

AFAIK no wifi is needed. I have taken it to beach cottages and hotel rooms with no internet connection and it works fine.

It is it's own internet server. Once it is set up, it will have its own WIFI address. One uses the device by logging your phone, tablet on laptop computer onto it's WIFI address .

WiFi adapters come either preinstalled in the system and all you need to do is attach a small radio antenna to the back (included) or connect the USB dongle included in the box to the back of your computer. That will enable you to have and connect to any WiFi network within range. The drivers for the WiFi adapters are already installed. In your case, all you need is plug in the USB adapter, access your wireless router using the passcode that is set on it and you're good!

No. This will provide a computer with a wireless (WiFi) connection to a wireless router or access point.

Not necessary. All you have to do is be able to load the disk to your computer(that has WiFi) and plug in ANTENNA to any usb port. Wala! its working. That easy...

You don't need this device if you have access to WiFi. You don't need this device if your cell phone permits you to 'tether' other devices. In places where you have No WiFi, but where cell phone coverage, 3G/4G is available, and if your cell phone does not permit tethering, and if you have a device like a tablet or a laptop PC without a dongle, ....with which you want to access the internet, then this device is handy. It can serve multiple devices simultaneously. Of course, you need to install a sim chip with data service from the cell phone provider of your choice.
