Cannot connect ti Wi-Fi. Message says obtaining ip address but as soon as a remembered message on wi-fi network, wi-fi disconnects and starts scanning again. This process repeats itself but never connects to the wi-fi. I have followed samsung's advice by removing the sd card and battery but this has made no difference.

Turn on the Wi-Fi and connect to a network. Long press on the connected network and select Modify Network. On IP Settings drop down menu, select Static. Assign IP of your choice but leave other variable untouched.

Assuming you're trying to connect via wireless router. If you connect, but then aren't able to get to the Internet. I would something is wrong between the router to the modem to the wall (DSL/Cable modem) rather then your tablet device. You can connect your device to your router and you device will show it has a wifi connection, but beyond the router something may be amiss. Try seeing what you get from another device like computer or laptop. That might get you closer to your actual issue,

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.

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.

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.

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.

Wi-Fi settings determine whether iPhone uses local Wi-Fi networks to connect to the Internet.
Turn Wi-Fi on: Choose Wi-Fi and turn Wi-Fi on.
Join a Wi-Fi network: Choose Wi-Fi, wait a moment as iPhone detects networks in range, then select a network. If necessary, enter a password and tap Join (networks that require a password appear with a lock icon).
Once you join a Wi-Fi network manually, iPhone automatically joins it whenever the network is in range. If more than one previously used network is in range, iPhone joins the one last used. When iPhone is joined to a Wi-Fi network, the Wi-Fi icon in the status bar at the top of the screen shows signal strength. The more bars you see, the stronger the signal. Set iPhone to ask if you want to join a new network: Choose Wi-Fi and turn "Ask to Join Networks" on or off. Join a closed Wi-Fi network: To join a Wi-Fi network that isn't shown in the list of scanned networks, choose Wi-Fi > Other, then enter the network name. If the network requires a password, tap Security, tap the type of security the network uses, and enter the password. You must already know the network name, password, and security type to connect to a closed network. Some Wi-Fi networks may require you to enter or adjust additional settings, such as a client ID or static IP address. You can type it manually by login onto the Belkin's network page using the browser and by copying the static and dynamic IP address.

Hi, this issue is caused when message authentication code (MAC) address filtering is enabled on the Wi-Fi network, and the MAC address of the BlackBerry smartphone is not accepted.
To resolve this issue, add the MAC address of the BlackBerry smartphone to the accepted MAC address list for the Wi-Fi network.
I hope this information may help you to resolve the issue.
