Problem connecting Samsung TV to wi-fi via repeater

by vellasta / July 4, 2012 7:20 PM PDT

I have posted this in the Samsung manufacturer's forum, but not sure if that's the right place so i'm posting it here as well....

I have this strange problem connecting my Samsung tv to my network. Let me state the facts...

A. TV is a Samsung LCD C750 2010 model.
B. I am using the Samsung wi-fi dedicated dongle
C. My modem/router (2 in 1) is a Thomson Technicolor TG582n

Now,

1. With repeater switched off, the TV can see the wireless network, but the signal is very very low. Still, when it manages to catch the signal, I run the network test on the TV and the 4 steps run successfully. Internet apps work, however they soon fail due to very low signal.

2. I recently bought an Xbox, placed just next to the TV, and it simply wouldn't detect the signal... so I bought an Edimax EW-7416APn which I have configured as a Universal Repeater.

3. The Xbox now works perfectly fine, and indeed all my other wireless devices like laptops, mobiles etc.. are working perfectly with the new Edimax repeater - the strongest possible signal, full networking and internet functionality.

4. Then I thought, now that I have a repeater, why not try connecting the TV again through it. So I browse for networks, find my homenetwork in the list (showing an excellent signal, now that it is being detected from the repeater), select it, and enter the pass phrase.

5. I run a network test on the TV and:

MAC Address test: passes

IP/DNS test: passes

Gateway ping: FAILS


The TV has acquired an IP, so there is communication with the repeater and indeed with the router which has provided the TV with an IP address. I can even ping that IP address from my laptop (which is connected via cable directly to the router) - so definitely, there is some kind of communication between the TV and the router and the TV is indeed on the network. However, I've tried millions of combinations and the network test simply fails on the Gateway Ping.

I have tried with/without security, changing channels and a number of other settings, but to no avail. I have tried manual settings on the TV... setting a fixed IP just outside my DHCP range (192.168.1.251), subnet mask 255.255.255.0, and gateway and DNS server IPs to those of my router (192.168.1.254).

Since the TV connects fine (when it manages to do so due to weak signal) to my router, I tend to point my finger at my Edimax repeater.
However, since all other devices are happily connected to the repeater, I then tend to point my finger at the TV!
Or perhaps at the combination of both!

Any idea what I else I could try?

P.S. using cable is out of the question and moving the modem/router to bring it closer to the TV is out of the question too, due to my home layout.

Did you try to change the SSID of your network? It's possible the IP-address of the router is somehow stored with the network data in the TV. Changing the SSID is - in effect - the same as selling the TV to somebody else who connects it to his own existing wireless network. That should be supported by the TV, somehow.

Another option might be to reset the TV to factory conditions, somehow. Then even your SSID is considered new. But I would wait with that until someone more knowledgeable with this TV joins the discussion.

Thanks for the reply.

I haven't tried a different SSID for the simple reason that I'd like my other network devices (laptops, mobiles) to switch seamlessly between the router and repeater as i move around the house while remaining on the same connection. i read somewhere that when using the Edimax in repeater mode, i should assign the same SSID as my main network in order to appear as one. Will there be issues if I assign a different name?

Still what you said makes sense and I will try it out in order to exhaust as many possibilities as I can.

Note that the gateway address was, and still is, the address of my router, i.e. 192.168.1.254, so it shouldn't be a problem if it remembers the old gateway address. Am i making sense here? (shouldn't the gateway address always be set to that of the router that has access to the internet?)

Samsung Smart TV

Hi,

I also have a Samsung Smart TV however mine has built in wi-fi, i have also tried connecting it to the network using a wi-fi range extender and the TV didn't seem to like this.

I have tested two wi-fi extenders and no joy, in the end i bought a a Belkin AC1200 wireless router as it has the most coverage and the tv is now fine. Another option would be to use a powerline network extender which uses your home powerline to extend the network then you could use ethernet cable instead of wi-fi dongle.
