Tip

How to set up internet on Samsung Jet


Ensure that you have the appropriate network key code needed to enable you to access a secure Wi-Fi network.


If you are connecting to a secure Wi-Fi network with MAC address restrictions, you will require pre-authorisation for the router. You will need to find your Samsung Jet's MAC (Media Access Control) address. This is a 12-character code which may be needed by the network controller to enable the phone to connect. See Getting the Samsung Jet's MAC address below.


You can get to the Wi-Fi application either via the main menu or using a homescreen Wi-Fi Widget.
  1. To get to the Wi-Fi application via the main menu, press the MENU button (either on the home screen or the hexagonal button beneath)
  2. In the main menu, swipe your finger sideways to go through the menu pages until you see the Wi-Fi icon. Press to select.
  3. The Wi-Fi application opens.
  4. Alternatively, to use the Wi-Fi Widget, from standby, press the home screen. The Widget toolbar opens up.
  5. Scroll down to find the Wi-Fi Widget icon. Press the Wi-Fi Widget. The Wi-Fi Widget will pop up on the main screen.
  6. Press the Wi-Fi Widget on the main part of the display to launch the Wi-Fi application. The Wi-Fi application opens.
  7. Once in the Wi-Fi screen, press the large Wi-Fi button in the middle of the screen to turn it on. Wi-Fi is activated and the button turns blue.
  8. Press SEARCH Nearby Wi-Fi access points (APs) will appear as small circles on the display, with their names next to them.
  9. Press the circle representing the Wi-Fi Netowrk you want to connect to. An options panel appears.
  10. You can press CONNECT to connect to the network or press ADD if you want to add it to a list of preferred networks for easy access later.
  11. You are taken into a settings menu for the Wi-Fi access point. If the Wi-Fi access point requires a network key code, scroll down to the Network Key panel. Press to select.
  12. The numberpad appears. Type in the network key code and press DONE. You are returned to the previous settings screen. Press SAVE
  13. A list of connections appears. Press the back arrow button
  14. If you initially pressed CONNECT, the phone will connect to the selected Wi-Fi network and a confirmation message will appear. The display now shows the new connection, illustrated by blue dots linking the circles onscreen (Figure 15).
  15. If you initially pressed ADD, you will be returned to the Wi-Fi screen. Press the circle representing the Wi-Fi network you want to connect to. A pop up panel appears.
  16. Press CONNECT. You will be connected and the connection illustrated onscreen.
Press the back button to return to the home screen.


  1. From the home screen press MENU to enter the main menu (Figure 1).
  2. In the main menu, press INTERNET
  3. Choose which browser option you want (Home, Enter URL, Bookmarks, etc.) (Figure 18) and press to select. If you press Home you will be taken to the pre-loaded home page.
  4. If required, use the numberpad to type in an URL or scroll a list to select bookmarks. When an URL is completed press GO. Alternatively press the bookmark you wish to access. You will taken to the web page requested.



  1. Activate Wi-Fi and press SEARCH, as before.
  2. When the Wi-Fi access point you want to connect to appears on the display (Figure 8), press it to select.
  3. A pop up options panel appears (Figure 9). Press DETAILS
  4. Details of the Wi-Fi access point appear onscreen.
  5. Scroll down by dragging your finger up the screen. Towards the bottom of the settings list, DEVICE MAC appears, with a string of 12 charactesr beneath (Figure 21). Each handset has an individual MAC address, and this panel will display your Samsung Jet's unique Mac address.
Make a note of the MAC address. You will need it if you want to use the Samsung Jet's Wi-Fi to access a secure Wi-Fi network using MAC address restrictions. This can be added into the wireless router settings access list.

Why does my moto G from US Cellular get poor signal now that I switch my plan from the $50 plan to the $60 plan



Cellular Signal Boosters / Repeaters

Your cellular carrier can provide you with a "signal booster" device that can repeat and boost a cellular signal you already get in your house. For example, if you consistently have one bar of coverage but no more at home, a booster can take that one bar and turn it into more bars. If you have one or two bars of coverage near a window but no coverage elsewhere in your home, a booster near that window can capture the signal and boost it, providing a strong signal throughout the rest of your home.
Some carriers offer such devices very inexpensively - $50 or maybe even free - especially if you're in an area where they know they know they have poor coverage. T-Mobile now offers such boosters for only a $25 deposit, which you can get back just by returning the booster to them.
Contact your carrier - or look at their website - to see just what they'll offer you and for how much.



Femtocells / Microcells

A femtocell - or "microcell" - is a small, low-power cellular base station that connects to the cellular network via your broadband Internet connection. Essentially, it's a small cellular signal tower that will provide a signal in and near your home, connecting to the larger mobile network over your Internet connection. This makes it ideal for situations where you don't even have a signal bar of coverage you can boost at home. The only "catch" is that your Internet connection must have a high enough download speed. Different carriers require different minimum speeds, but you should be fine as long as you have a solid broadband connection.
Ask your cellular carrier if they offer this sort of product and find out how much it will cost you. As with boosters and repeaters, a femtocell may be available at a steep discount from your carrier in areas they know they have poor cellular service.
You can also buy them easily on Amazon or almost any decent tech store - for instance the one pictured below works for AT&T and supports LTE (though it is a bit pricey), or you can get one that supports Verizon, T-Mobile, AT&T, Sprint, Cricket, and many others, but you won't get LTE support. Of course, since you likely have Wi-Fi in your house, LTE isn't really a big deal and the 3G will work just fine for calls and texts.
Editor's Note: For the official How-To Geek office we got a Samsung microcell device directly through Verizon, which wasn't cheap, and doesn't work all that well. And since it only works for Verizon, any of the people who come by who use other carriers have zero signal, which is really annoying. If we could do it over again, we'd have started with this zBoost microcell that supports virtually every cell provider and has many different models and options to choose from depending on the size of the house. They even have an optional antenna you can install on your roof to give cell coverage everywhere around your house. It's the best choice, and cheaper than most carriers will offer you.



Wi-Fi Calling and SMS


Wi-Fi calling is a feature you might remember from some years ago, but it's coming back with a vengeance. At the moment, in the US, only T-Mobile offers Wi-Fi calling for both Android phones and the iPhone. Sprint only offers Wi-Fi calling for select Android phones. AT&T and Verizon have announced plans to activate Wi-Fi calling in 2015.
Essentially, WI-Fi calling allows your smartphone to receive and place calls and communicate via text messages over a Wi-Fi network. Your home probably has Wi-Fi, so Wi-FI calling will let you use your existing wireless router instead of needing a new, specialized device. You can just improve your Wi-Fi signal strength, and all your devices will benefit!
Wi-Fi calling works transparently. When your phone is on Wi-Fi and has a poor cellular signal, it will connect to the Wi-Fi network and your phone calls and text will be sent and arrive over the Wi-Fi network. When you leave the Wi-Fi network, your phones and calls will be sent over the cellular network as usual. This is all designed to hand-off automatically, so you could start a phone call on your Wi-Fi network and your phone would automatically hand off to the cellular network as you walk out the door, with no interruptions.



WI-FI calling will also work on other WI-Fi networks, so it's helpful if you ever end up in another place where you have a poor cellular signal but have Wi-Fi. To use this, you'll need to ensure your phone has Wi-Fi calling support and that it's enabled. Android phones from T-Mobile and Sprint will often include this feature, so look up how to enable it on your specific model of Android phone.
The iPhone 6 has built-in Wi-Fi calling, although it currently only functions on T-Mobile. AT&T and Verizon plan to support it in 2015. To enable this feature on an iPhone, open the Settings screen, tap Phone, tap Wi-Fi Calling, and activate it.

WI-Fi calling seems to be the future goal the industry - T-Mobile, especially - is pushing towards. With Wi-Fi calling integrated into your phone, you don't need to buy a specialized device. Your home Wi-Fi router works. And, when you go somewhere else where you have a poor signal, all they need is a Wi-Fi network and you'll be able to get a phone calls and SMS messages through it.

My wifi stop working,i dont know why???


Solutions to Common Android WI-Fi ProblemsFriends of mine who use an Android come over to me usually with problems related to their devices' Wi-Fi connectivity. Moreover, it's not a single isolated issue. There are all kinds of them they bring up. I usually fix their problem after few troubleshoots but today while I was fixing a problem on my device, I realized that it could happen to any one - even to my readers on Guiding Tech. Hence we are going to discuss four of the most common Android Wi-Fi problems and see the probable causes and solutions to them.
Android Cannot Scan a Wi-Fi Network Reason
There may be two reasons as to why your Android cannot scan a network automatically. The first reason may be that the network you are trying to connect to could be Ad-Hoc in nature. As most of the Android phones are not configured to work on Ad-Hoc networks but on access points, they don't scan them.
The second reason may be that the Wi-Fi network you are trying to connect to might be hidden for security reasons.
Solution
By default, Android does not support Ad-Hoc Wi-Fi network but many developers patch the wpa_supplicant file on Android in order for them to work. If you do a quick Google search you will be able to find if there's a fix available for your device but the fix can only be performed on a rooted phone. Furthermore, don't forget to back up your original wpa_supplicant file if at all your phones goes into foreclose or boot loops.
ad55c1b5-6c69-4c6f-bbc4-42d71b214047.png
If the problem is with the hidden network, you can try to add the network manually. In Android Wi-Fi settings open menu and tap to add a network manually. You must enter the correct SSID and authentication type and password in order to connect to the network. If both the credentials are correct, the Android phone will be able to connect to the network.
Wi-Fi Keeps Disconnecting Frequently Reason
The most obvious reason for the problem may be with the Wi-Fi Sleep Policy which disconnects your Wi-Fi every time your Android goes to sleep to save your battery's juice.
Solution
To manage Wi-Fi Sleep Policy, open Advance Wi-Fi settings on Android and tap the option Keep Wi-Fi on during sleep. Here, check the option Always to enjoy an uninterrupted connectivity, but you will have to compensate it with your battery life.
75ca1d6c-6a65-4f45-a239-1e913ecb07bc.png
If you are using any third-party app to save your battery, check if it's controlling your Wi-Fi and other radio services and configure accordingly.
Obtaining IP Address Infinite Loop Reason
I don't know the exact reason behind this, but it might be a bug in Android. I have seen many people getting this problem, and it gets kind of annoying when the problem does not gets fixed even after restarting the device.
Solution
First of all, you must restart your Wi-Fi router and see if that helps. Many people say that resetting the phone to factory state works but that's not an appropriate solution. Wi-Fi Fixer is an amazing Android app that can help you here. The app resets your Wi-Fi system files (same as when you reinstall the Wi-Fi drivers in Windows, or you disable and enable the Wi-Fi adapter) and services and helps you to connect to the network and obtain the IP address.

    wifi-fixer.png If you know the range of IP address the router is broadcasting, you may configure your Android to use static IP address while connecting to the network.
    Can't Connect to Internet using Wi-Fi Reasons
    There may be several reasons as to why you are not able to connect to the internet even when you are connected to the Wi-Fi. The reasons may be:
    • The router is not broadcasting internet services.
    • The IP address or the gateway is wrong.
    • Problem with the DNS settings.
    Solutions
    You may use another device to check if the router is actually broadcasting internet. Also you can configure the IP address, the gateway and DNS manually to connect as their might be problems with DHCP.
    Conclusion These are pretty much most of the Android problems one might encounter on his device and the probable solution one can try to fix the problem. I don't guarantee that you will fix the problem but it's a good start nonetheless. And most of the solutions should work actually.

I have a blackberry 8120 on pay as u go but i carn't use the internet how do i do it


If its on Orange and has the new software version on it which I'm guessing it does as the new version was out over a year ago then the only way you can access the internet is via wi fi.
For some reason Orange decided it was more usual for Blackberry owners to connect to a network other than a mobile network. You will also find that you cannot send mms messages for the same reason.
There is a way of going back to the old software on the phone but you will have to do a lot of googling to find out.

Sorry!

Connections problems


I had that problem in the beginning with my iTouch.
Have you checked your IP address?
Try opening settings, then open Wi-Fi, then touch the blue circle with the arrow in it that's next to your Wi-Fi router's name.
Once you're looking at a screen with your network's name at the top and your iTouch's IP address in the middle, scroll to the bottom of the page and touch "Renew Lease", then confirm by doing it again on the popup.
Now, scroll back to the top of the page and wait a moment. You should see the IP address go blank and then a new number should appear.
Hopefully you're online, check by opening App Store or Safari.
If not...
Turn off your iTouch competely (hold the lock/power button until the "slide to power off" slider pops up, then slide it).
Next, turn off your Wi-Fi router and modem.
Wait 5 full minutes.
Turn on your modem, wait 2 full minutes.
Turn on your Wi-Fi router, wait 2 full minutes.
Turn on your iTouch.
If all that doesn't work, call Apple Care... 1.800.692.7753
If you have any questions, please feel free to call me.
