How to Fix Wireless Connection Issues on Galaxy Tab 10 After Router Change?

It sounds like your tablet is having trouble connecting to the new network, even though other devices are connecting without issues. One thing you can try is to change the IP settings on your tablet. When you're connected to the network, tap and hold the network name until a menu appears, then select "Modify network." From there, look for the "IP settings" option. If it's currently set to DHCP, switch it to Static, but make sure you have the correct IP address, gateway, and DNS settings from your IT support. If that doesn't work, try restarting your tablet. Press and hold the Power button for about 10 seconds to restart it. After it powers back on, go to Settings, then Wireless & networks. Tap and hold the network you're trying to connect to and select "Forget network." After that, try reconnecting to the network. If you're still facing issues, it might be worth considering a factory reset of your tablet. This will erase all data, so make sure to back up your important files first. You can use Samsung Kies for the backup. Once you have it installed on your computer, connect your tablet, launch Kies, and follow the prompts to back up your data. After the backup is complete, you can reset your tablet by going to Settings, selecting Privacy, and then choosing Factory data reset. Once the reset is done, you can restore your data from Kies. Just connect your tablet again, go to the Backup/Restore tab, and follow the prompts to restore your files. If these steps don't resolve the issue, it could be that the network's security settings are incompatible with your tablet. In that case, you may need to consult with your IT department for further assistance.
