LG UN 7350 PTA auto Wifi connection is takes approx. 4 minutes to WIFI router/hotspots


Recommended Posts

Hi All,

Purchased LG UN 7350PTA 43 inch tv 7 days back. 

Steps for reproduce

1. Configure TV WIFI with WIFI router

2. Turned off TV

3. Turned on TV

4. Takes approx. 4 minutes to auto connect WIFI, at that WIFI searching time, i did not even seen any WIFI name, it populated  all WIFI available after 4 minutes.

Contacted LG Customer care, He told it takes  4 minutes to connect WIFI. nowadays Mobile phone is takes approx. 30 seconds  to connect WIFI. 

Note: tried with mobile hotspots, it is same behavior. it could be SW issue from LG TV. Reset TV 2 times but no luck

@Vijay Kumbhani If you check your smart phone WiFi "bars" in the room where the TV is located  (NOT the phone network signal bars), does the strengh look "good" (i.e. all arc lines), or just a couple highlighted?

Is the TV using a 2.4GHz band, or a 5GHz band?  Which is the best/strongest signal in the TV room?  What channels are those bands using (log into the router, go to config -> WiFi -> advanced settings to check). If on defaults (say 1 and 100), change them to channel 8 for the 2.4GHz, and 36 for the 5GHz, and ensure that the SSID names are 8 characters or less, with NO special characters in the name.

The router make and model would be useful to know.

Hi 

Thanks for reply,  I given remote support to LG customer care executive. They said setting are fine and good. They said it takes approx. =~ 4 minutes to connect Wi-Fi, that answer is not valid.  explained LG customer care, can check wifi on your smartphone, it takes less than 1 minute to connect. 

I observed few things, One TV power on, I  went to Connection  -> WIFI Connection, it shows cursor stuck even didn't turned off WIFI at that time, I will need to wait approx. =~ 4 minutes after that I will change WIFI settings. I think, This is Web Os Bug.  

Is the TV using a 2.4GHz band, or a 5GHz band? 

I think 2.5 GHZ

Which is the best/strongest signal in the TV room?

strongest

BTW, attached Image

I think actually I found issue, it looks like web os SW issue.

Open Netflix on Tv after TV on. But Netflix is playing video after 30 seconds at that time Network WIFI option is in waiting for connect to internet. 

Rest of all apps except Netflix working.

Once Network WIFI option show connected to internet after that all apps work.

 

It looks like, rest of the all apps is checking network status of Web OS SDK.

@Vijay Kumbhani The picture does no really show us anything, other than the TV settings UI is waiting. Did you check with your smartphone as requested in my previous post, to see the strength of the WiFi arc/bars ICON at the top of your phone, when near the TV? Do you know if the 2.4Ghz and 5GHz WiFi bands are using the same SSID name, or have different names on your router? Some routers have them the same, which makes it difficult to know which band you various devices are connected to. The signal strength   by the TV would be useful to know . How far is the TV from the router by the way?

If you have a Windows 7 or 8.1, or Windows 10 laptop, download the excellent utility from NIRSOFT, called WiFiInfoView, that will give you details of ALL reachable WiFi routers and SSID names "near" you. Of course the strongest signals are going to be the ones from YOUR router, and even if the SSID names are the same for both bands, this utility will show your both, and the strength and quality of the signals for both bands. It is also useful to find if your neighbours routers are using the same channels, so you can check your router, log in and change the channels to ones with less interference (see my earlier post reproduced below for suggestions on that).

NOTE: the download link is about three-quarters of the way down the page. When downloaded, unzip the ZIP file into its own empty location, then double-click on the .EXE file inside your newly created folder for that program.

In case you missed it, here is my previous recommendation to follow, and suggested WiFi channel numbers to try. Also, if yo have a very old router, that could be your issue (e.g. an N600), so please post the make and model of your router).

@Vijay Kumbhani Are you saying that by changing the DNS server to  8.8.8.8 fixed your slow WiFi startup? 

If your router DNS service is set to that (8.8.8.8 primary with 4.4.4.4 as secondary DNS server), then the default in the TV would be to use the routers setting, that should use what the router is using anyway.

The automatic settings leave it to use your ISP DNS services, which is not always the most secure or safest thing to do.  If you are saying that the default setting in the TV is slow (and you have your router already set up for 8.8.8.8/4,4,4,4), but using 8.8.8.8 in the TV DIRECTLY (i.e. specifically defining it there) stops the slowness issue, then that is definitely a buggy situation with the LG TV WiFi  DNS usage and operation.  Unless of course you have some unusual or special advanced DNS settings in your router, or you have IPV6 services enabled, or an IPV6 server setup (not normally necessary for Home Networks).

      LG Continues to Push the Limits of Future Mobility with Advanced ADAS Technology

      SEOUL, Nov. 25, 2021 — LG Electronics (LG) and Mercedes-Benz AG were named joint winners this week at the annual AutoSens Awards, a global celebration of autonomous driving and advanced driver assistance systems (ADAS).
      Every year the AutoSens conference recognizes companies for innovations in six categories of which LG was nominated in two: 2020 Vision Award and Hardware Development of the Year. The 2020 Vision Award was bestowed to LG and Mercedes-Benz in recognition of their influence, sustainability, contribution to the industry and inspiration to future technologies. The Hardware Development of the Year award was given to LG for successfully commercializing its front multipurpose camera technology beyond the concept stage. LG and Mercedes-Benz have been on ADAS camera technology for the past seven years, seeing the fruits of their labor commercialized in the new sedan which launched last month.
      First started in 2015, the AutoSens Awards celebrates the best innovations and innovators in ADAS and autonomous vehicle technology. Every year, representatives from automakers, suppliers, research labs and academia take part in AutoSens online communities, conferences and training modules, exhibition events and workshops to better understand the fast-growing autonomous vehicle industry, which could not exist without ADAS technology.
      Dr. Park Young-kyung, a Vision AI expert at LG, and Dr. Benjamin Marx of Mercedes-Benz’ multi-purpose camera team accepted the award and delivered a speech where they described the rewarding experience of working together for many years to develop a camera solution that improved real-life safety and met the strict European NCAP safety requirements. The state-of-the-art technology developed by the two companies is capable of taking advantage of deep learning and multi radar sensors to deliver significantly more environmental data to the central processing unit for analysis. More data results in better analysis and greater safety.
      “Demonstration value to our automotive customers is the ultimate reward for LG,” said Dr. Kim Jin-yong, president of the LG Vehicle component Solutions Company. “Being honored together with Mercedes-Benz is very meaningful to LG as we strive to contribute toward innovation in future mobility.”

      Hi
      I've got an LG Smart TV 43UM  7400PLB and am looking to buy an external hard drive so I can pause live TV and record programs. I'm currently using a much smaller capacity USB which can't pause live TV and will soon be full. 
      I've read on various forums that certain hard drives won't work or that I'll need to buy a certain connecting cable. 
      I was thinking of buying a Seagate 2TB drive, (STGX2000400) which is around £55.
      Can anyone recommend one or confirm that the Seagate one will be okay.
      Thanks.

      Good evening.
       
      I have a LG 43UK6950PLB, a few years old.
      Suddenly yesterday most things stopped working. 
      The apps just freeze and won't load,
      The remote cursor has disappeared,
      If selecting a different input, it won't load that input and just freezes. 
      Wifi isn't connected, however it can find my router in the menu, just won't connect. 
      I've carried out a reset, unplugging, and turning off standby mode etc to no avail.
      Any help appreciated, thank you.

      Hi, 
       
      I was tying to change the settings on our LG TV to enable it for HD channel reception. We found instructions on the net to configure the "area option" in the hidden menu, however, they did not work. So, we thought that we need to change the country group to be able to receive the HD channels. Although we could not change the "country group code" from 20 to an arbitrary number, we change it to 10. After that, we have not been able to change it anymore. It is struck there. I know this is ridiculous, but an LG TV expert who is working in LG customer services told us that I could not change it either and we need to replace the IC. I shocked why with a simple change in one of the TV parameters, everything is got complicated. 
       
      In details, here is the picture of the parameters currently set on the LG TV with the model number of 49LH549V-TD: 
       

       
      Please tell me why I could not set the "country group code" to 20 once again? It is gray meaning that is unchangeable. Any ideas will be appreciated.
       
      Best regards 
      Alizadeh

      LG's webOS 6.0 smart TVs have a new UI, NFC-equipped remote
      The new smart TV software from LG also has more voice commands for use with Alexa or Google Assistant

      Seven years after introducing webOS as the platform for its Smart TV lineup, LG is introducing version 6.0 with a new look and feel for its 2021 4K and 8K TVs. The old blade lineup of apps is gone, with a more modern tile-based layout. LG Home Entertainment president Park Hyoung-sei calls this “the most significant update since we first introduced webOS in 2014.”

      An upgraded version of its ThinQ AI has more voice command control than ever whether you’re using Google Assistant or Amazon Alexa. For traditional control, this year’s edition of its Magic Remote is a bit more standard than some of the previous versions, but also includes NFC for the first time, which allows users to share content from phone to TV (and back) simply by tapping it.
      The new software includes Magic Explorer, which can pull up related content about actors, locations and items of interest for “select broadcast channels, while Next Picks analyzes viewing preferences to suggest things you might like. There’s no word on opt-in or opt-out preferences for these settings, but we’ll ask about them as the show progresses next week. It’s also unclear whether the updates will extend to older TVs in LG’s lineup, one way or another, the old HP software platform is still rolling on, powering new OLEDs and LCDs for another year.
