Hi all

I'm really hoping somebody might be able to help me with a problem I'm having trying to connect my Samsung Smart TV to the Internet.

I purchased the Samsung EH5300 yesterday and have connected it to my router (ZyXEL P-660HW-T1) via Ethernet. This works fine and picks up all the settings (ie: IP address, gateway etc) automatically and I can connect to the Internet fine.

The problem comes when I then connect any device to the router using Wi-Fi - this could be my iPad, iPhone, PC, laptop - anything will disconnect the wired TV connection immediately from the Internet but it DOES NOT disconnect it from the network. In other words, I can still see the TV in the list of devices on my router and still ping the IP from my PC. All the settings on the TV remain the same but when running the network test, it says it is connected to the network but not the Internet.

I have disconnected all cables, reset the router, turned everything off and on several times, placed the Ethernet cable in different ports on the router, manually input all the IP addresses etc but none of it is working.

I've no idea why on earth it is doing this so please does anybody have any ideas or suggestions of what I can try?

Thanks very much for any help!

Steve

can you post the ip settings on the TV

and an ipconfig /all from a working PC

is it only wireless thats the issue - if you connected another PC to the router by cable does that work ok

------------------------------------------------------------------------
ipconfig /all
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

We would like to see the results from an ipconfig /all - post back the results in a reply here.

This should also work for windows 8
Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box
(A new dialogue box - black with white font, will appear on screen ):

In the command prompt window that opens, type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

ipconfig /all > network.txt & network.txt

It will export the results into notepad and then automatically open the notepad and display on your screen.

Now all you need to do is copy and paste those results into a reply here
to do that:
From the notepad menu - choose Edit - Select all
all the text will now be highlighted
Next
From the notepad menu - choose Edit - Copy

Now go back to the forum - goto the reply and then right click in the reply box and paste the results.
The results from the notepad should now appear in the forum reply.

Thanks for your reply

Yes, wi-fi is working fine and always has. I have 1 ethernet cable plugged into my router for my VoIP phone which is working absolutely fine and the only other ethernet cable is the one for the TV.

I have just tried connecting the ethernet cable to my PC - everything worked. I then connected my iPhone to Wi-Fi and, as expected, it disconnected the Internet on the PC (but still connected to the actual network). So, I'm assuming there is a problem with the router setup/settings??

The IP settings on the TV are:

IP Address: 192.168.1.34
Subnet 255.255.255.0
Gateway 192.168.1.1
DNS 192.168.1.1

And here are the results from the ipconfig...

Yes, looks like an issue with the router
as its occurring on the PC and the TV when connected by Ethernet
we may try a factory reset on the ZyXEL P-660HW-T1
But need to make sure we know the settings, username and password etc , before doing that

with a pc when it disconnects would you do the following
ipconfig /all and three ping tests

------------------------------------------------------------------------
Ping Tests
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

Start> Run {search bar in Vista/W7}> type CMD to open a command prompt box
(A new dialogue box - black with white font, will appear on screen ):

For Windows 8
to open a Cmd Prompt or an Administrator Cmd prompt from the Desktop. Use Win + X and choose Command Prompt or Command Prompt (Admin) from the list.

Type the following command
Ping {then a space and then add the number that is shown against the item labelled "default gateway" shown in the results from the ipconfig /all}
Post back the results in a reply here
right click in the command prompt box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste

Type the following command
Ping google.com
Post back the results in a reply here
right click in the command prompt box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste

Type the following command
Ping 209.183.226.152
Post back the results in a reply here
right click in the command prompt box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste
Quote:
For your information only
these tests will check various stages of the connection, the first ping test, ping default gateway checks to see if you still have a connection to the router.
The next two Ping google.com & Ping 209.183.226.152 tests the connection to internet. google is to test by name and the ping test using a number is checking that a connection exists without DNS.
these tests then confirm if there is a dns issue on the connection.

Thanks for your help.

FYI, I have already reset the router to factory settings and unfortunately this hasn't fixed the issue.

Here are the results from the ipconfig /all and ping tests on a PC connected via Ethernet with a cable and working - until Wi-Fi is connected at which point Internet is disconnected.

You may try a firmware update on the router from the manufacturer's website.

Do the update using a wired connection only not wireless connection and please do not interupt the update as this may brick the router to do so.
