Samsung smart tv cant find any network connections

Which security protocol are you using on your wireless network and what protocols are compatible with your smart TV?

Here is your manual. Given the symptoms, I would guess that your wireless network does not broadcast itself (hidden) and therefore you should follow the steps on pgs 160-161.

Hi Mate,

Did you fix this? I have the exact same problem

i also have this problem.
I can connect with a cable but not through an adapter.
Are the adapters faulty?

I also have internet connection prob. I use cable to connect to my router, but the gateway test failed. when I plug my cable to the laptop, the internet connection works fine.
can anyone help?

I'm not sure if this will help or not but this is what finally worked for me. after trying for hours to figure this out. I too have multiple clients connected to my router but since the router was outdated I upgraded to a new one.

Still the same issue. Finally I decided to set the IP settings in the TV manually then pressed ok. I then turned the TV off for about a minute turned it back on then checked the network status on the TV menu.

I'm not sure exactly what the problem was but it was very reluctant to let go of a wrongly acquired "obtain automatically" settings. Just setting the IP settings manually won't fix it either unless you turn off the TV wait a minute then back on.

Hope this helps someone.

I have the same problem on my samsung tv ua46eh5300 and wondering if you find any solutions. My smart tv won't find any Internet while my wirless is fine because I have access to the Internet from other devices my pc or I pad. However, still can not connect my tv to the Internet.

I had the same problem and couldn't find an answer, so I did some trial and error and got it working  
Firstly update the TV firmware, you can do this by going to Samsung's support page and downloading the firmware for your set.. or plug in a LAN cable (setting the network through LAN) pressing menu-support-software update on your remote. I downloaded onto my laptop, opened the file and saved it to a USB stick, then did the above update method clicking on the use USB option.

Once the firmware is updated try searching again (make sure the LAN cable is out, otherwise it just sticks to using it and wont search) and hopefully it works.
If not don't panic as mine still didn't either.. so I turned the tv off for 2 minutes, turned it back on and BAM
UP AND ONLINE THROUGH WIRELESS
