How do I connect to the internet when I am not connected to home Wi-Fi connection? I get an error message even though it shows I have a 4G connection.

I assume you're using a secure Wifi connection with a password and it seems like that authentication is not working. You could try using an open wifi access point to eliminate the possibility of this authentication issue.

Hello Ricardo.
How are You? I Guess you need to
1- Check your wi-fi router model.
2- Check your wi-fi settings.
also please check how many devices are connected to your wi-fi at same time. because some routers can only support upto 5 device. you can check this in the settings and also routers manual.

Please let me know, once you done with it.

Regards

Okay, is this your mobile network (3G/4G) or your home network (Wi-Fi)? Is your service running? You should always be able to access the internet via Wi-Fi even if you don't pay your bill. Try updating your data profile. Are you paying for internet with your current plan? If not, upgrade your plan. These are just a few solutions to many reasons you cannot establish an internet connection.

Samsung Epic 4G Phone into a Wi-Fi Hotspot

The Samsung Epic 4G smart phone allows you to convert your phone into a Wi-Fi hotspot and connect up to five devices.
Such a set-up will keep you from running around searching for an area that offers free Wi-FI. If you're stuck in an airport or staying overnight at a hotel, you won't have to pay extra for Internet service.
You can connect your laptop or other media device to your phone's Wi-Fi network.

Press the "Home" button, which looks like the outline of a house, on the bottom of your Samsung Epic 4G phone.
Click the "Menu" button to the left of the "Home" button.

Click the "Settings" icon, which looks like a gray box with a spoke in the middle.


Scroll through the list and click "Wireless & Networks."


Press "4G" until a check mark appears, indicating the 4G network is enabled.


Click the "Home" button.
The 4G icon will appear to the left of your signal bars in the upper-right corner of your screen.
The separate sets of bars above the 4G logo indicate the strength of your 4G signal.
When the bars above the 4G logo are completely gray and the 4G logo is white, you have a weak signal.
When you are no longer receiving a 4G signal, your 4G logo will be gray and a 3G logo will appear, indicating that the 3G network is now enabled. If both of the logos disappear, you are not receiving any signal.
You must have either a 3G or a 4G signal to use your phone as a Wi-Fi hotspot.

Enable Sprint Hotspot
Press the "Applications" icon, a blue box with four whites squares in it, in the lower-right corner of your Samsung Epic 4G phone.

Press the "Sprint Hotspot" icon, which looks like a phone with two signal bars on the right side, until a check mark appears to the right of the icon, signaling the Spring hotspot function is enabled.
A pass-key allowing you to connect other devices to the phone's network will appear on the screen.
Write the pass-key down.


Enable Wi-Fi on your laptop or other device that you want to tether to your Samsung Epic 4G phone.


Search for the Wi-Fi network affiliated with your Samsung Epic 4G phone.
The name of the network will begin with "SPH-D700XXX."
To change the name of the Wi-Fi network affiliated with your Samsung Epic 4G phone, press the "Menu" button; the "Settings" icon; and "Device Name." Enter the new name for phone's Wi-Fi network.


Click the network affiliated with your Samsung Epic 4G phone on the device you want to tether to your phone'ss Wi-Fii network.
Enter the pass-key, and click "OK."
Your device will now be tethered to the Wi-Fi hotspot on your Samsung Epic 4G phone.

You need to have either a wi-fi or 3g/4g connection and a browser installed on your phone. No other setup is required

Hello,

You have to ocnnect your iphone to internet first , Follow below step to connect to internet

When you use any Internet enabled application, iPhone does the following in order until connected:

1. Connects over the last Wi-Fi network you used that's available.
2. If no Wi-Fi networks you've used are available, shows a list of Wi-Fi networks in range. Tap a network and, if necessary, enter the password to join. Networks that require a password show next to them.
3. If no Wi-Fi networks are available or you choose not to join any, iPhone connects over the cellular data network.

Note: You can be on a call and use Wi-Fi or 3G1 at the same time. Other cellular data networks are unavailable while you're on a call.
Wi-Fi

• Wi-Fi is often faster than cellular data networks. Wi-Fi networks cover limited areas. iPhone can join AirPort and other Wi-Fi networks at home, at work, or at Wi-Fi hot spots around the world.
  When iPhone is connected to a Wi-Fi network, the Wi-Fi icon in the status bar at the top of the screen shows connection strength. The more bars you see, the stronger the connection.
• To see all the Wi-Fi networks in range, from the Home screen choose Settings > Wi-Fi. Tap a network to join it.
• Many Wi-Fi networks can be used free of charge, and some require a fee. To join a Wi-Fi network at a hot spot where charges apply, in most cases you can open Safari to see a webpage that allows you to sign up for service.

For information about configuring Wi-Fi settings, see the "Wi-Fi" section of the iPhone User's Guide.
Note: iOS devices sold in China may use the term Wireless LAN (WLAN) instead of Wi-Fi. Not all China iPhone models support WLAN; see this article for more information.
Cellular data networks

• Cellular data networks allow Internet connectivity over the cellular network. Check your carrier's network coverage in your area for availability.
  You can tell iPhone is connected to the Internet over a cellular data network if you see , or in the status bar at the top of the screen.
  If you're outside your carrier's network, you may be able to use a cellular data network from another carrier. Roaming charges may apply.
  Note: If not on 3G, while iPhone is actively transferring data over the cellular data network-downloading a webpage, for example-you may not be able to receive calls. Incoming calls may go to voicemail.
  

I hope , after this , you will be able to connect to Internet....

Thanks
Sandeep
