Problem: Article: Some models may require you to reboot the system before the changes take effect. Connect a computer, phone, or tablet to the same network as your Smart TV to test whether the network is working properly. If you're unable to browse the web on the network, the issue may be with your router or ISP.  Try rebooting your Wi-Fi router/access point, as that often resolves network issues. If you're having trouble getting online using any device on the network, contact your ISP for help. If your Wi-Fi router has any sort of MAC filtering set up, you may need to manually add the TV's MAC address to allow it internet access. Here's how to find the MAC address of your Smart TV:  Open the Settings menu on the TV. Select About this TV or Contact Samsung (the option varies by model). Scroll down to find the MAC address, which looks like 6 pairs of letters and/or numbers separated by hyphens (-). If your network is performing fine but your TV isn't able to connect, it could be because of the distance between the TV and the wireless access point. If possible, put both devices in the same room with a clear line-of-sight (no walls or tall furniture between the two). Samsung recommends placing the router within 50 feet of the Smart TV, but the closer the better.  If it's not possible to move closer to the access point, try using a Wi-Fi extender to boost the signal. If you're in an apartment or condo, neighboring units could be using devices that impact your wireless performance. Moving the TV and/or router away from shared walls could help. If the wireless connection isn't working, you can connect your TV to the router with an Ethernet cable. Here's how:  Insert one end of the cable into the port on the back or side of your TV, and another into an available LAN port on your router/access point. Press the Menu or Home button your remote and select Network. Select Network Settings. Select Network Type. Select Wired. Select Connect. If the issue isn't with your internet provider, you may need to update your TV. Since the TV isn't online, you'll need a computer with internet access and a USB flash drive to download the update.  Go https://www.samsung.com/us/support/downloads on a computer. Select your TV model. Download the latest firmware update to a USB drive. Connect the drive to your TV. Press the Home or Menu button on your remote and select Support. Select Software Update and then Update Now. Select USB and follow the on-screen instructions to apply the update.
Summary: Turn your Smart TV off and then back on. Make sure your Wi-Fi network is online and working properly. Check your Wi-Fi router settings. Move the wireless access point closer to the TV. Try a wired network connection. Update the firmware on your TV.

In one sentence, describe what the following article is about: Your doctor may recommend that you do a prenatal screening for cystic fibrosis if the disorder runs in your family or if you are a carrier of the defective gene that causes it. The test is usually very accurate and can tell you if your baby’s genes are normal or if they are at risk of developing cystic fibrosis. However, taking this test is a very personal decision that you should discuss carefully with your doctor and your significant other, if they’re involved. Talk about the pros and cons with your doctor and educate yourself before you decide to have a test done. Your doctor will put a needle into your abdominal wall and then into your uterus. They will extract a small amount of fluid from the amniotic sac, which is the sac that is around your baby. This test can be done at your doctor’s office and should not be painful for you. Another prenatal test involves the doctor threading a thin tube into your vagina and cervix until it reaches the placenta. They will then suck out a sample of the placenta for testing. The suction used will be gentle and should not be painful or uncomfortable for you.
Summary:
Consider a prenatal test if you are pregnant and genetically prone to cystic fibrosis. Consider allowing your doctor to remove fluid from your amniotic sac. Talk with your doctor about taking a sample of your placenta.
