Network connection issues. LG Content store doesn't connect.


Recommended Posts

I did a refresh of my LG TV 3 days ago. Sold the old LG 47" 3D LED TV and bought new 55" LG Super UltraHD TV with WebOS. I believe, the biggest con of this new TV is WebOS. Its totally frustrating. Sorry for WebOS fans.

It isn't that smart and functional they way it looks. The problem I having since 3 days and being a network engineer, I am unable to solve a network issue myself which is even more frustrating for me.

Ok, let me explain the issue. The TV when installed was connected to LAN cable to my router which has direct internet connection. The TV works and none of the apps were working. Basically TV wasn't able to connect to internet via apps. If i open web browser, it was working fine with all webpages showing correctly.

I'll skip the part of contacting LG support which was useless. All troubleshooting steps like resetting, formatting, changing time zone, location, region was done but no luck. Finally I connected the TV via mobile hotspot and it just worked which gave me the clue that some ports are being blocked by my ISP or router.

My internet setup is this way. Internet cable from ISP -> ISP Modem (can do NAT and work as router) - WiFi Router (NAT, DHCP, etc) -> all LAN clients. I put my LG TV in DMZ, opened all ports, etc but no luck. Then I converted my ISP modem as router and connected the LG TV directly to it and it started working..!!!

My WiFi Router is TP-Link Archer C7 and I was using stock firmware. Thought it was creating issues and I installed DD-WRT, Open-WRT but no luck at all. The apps which were installed in TV when TV was connected directly to modem are still working fine. Youtube, Plex, Netflix, etc all are working but when I open LG Content Store, it just refuses to load.

I am not sure what wrong my TP-Link router is doing. There is something wrong with the LG TV content store. If it requires to open ports, then I would like to know which ones.

Sorry for the long port, may be my frustration of 3 days with no luck.!!

Hello guys As an experienced LG Oled TVs I can suggest one option to solve all kind of WebOs function. Since it’s computers I always  unplug the power cord from the wall for few seconds . Us

Ah yes after twenty years in the computer support industry myself it is amazing how many times the solutions of turning off/unplugging and turning back on again works.

Same issue here. I first noticed my issue when I tried to open Sling TV app. It required an update which tried to take me to the LG Content Store. Then I would get an error message that the LG Content Store is temporarily unavailable, try again later. This has been going on for a month with absolutely no help from LG Technical Support. Most other apps (Netflix , Amazon Video, etc.) all work fine. I was finally able to get into my router management and disable the firewall while I tried to update the Sling app. It worked long enough to update the app. But after a few minutes, I got the “temporarily unavailable “ message from the LG Content Store again. Very frustrating!

As crazy as this sounds try this, unplug your tv for a few minutes then plug it back in. I’m a computer repair tech and have years of experience in a variety of electronic troubleshooting. 

I was having this same issue when I ran across this fix that seemed so silly but it werked!!

Ah yes after twenty years in the computer support industry myself it is amazing how many times the solutions of turning off/unplugging and turning back on again works.

Well unfortunately the "unplug from power source" doesn't work for me. I live in South Africa we are currently having scheduled power outages  for +/-  3 hours daily even that prolonged period of "unplugging" doesn't work. What's even more strange/annoying is that the LG content store & all other apps won't work on a wired connection directly connected to my ISP modem/router on FTTH (using Google DNS) but NETFLIX works without a single glitch all the time.  I keep getting the "CHECK NETWORK CONNECTION (-118)" error message on the wired connection.

I'm almost convinced that the wired connection takes second preference to a wireless connection as I can access the content store & the rest of the apps via a cellular broadband connection (without using Google DNS) even though the wireless doesn't work at all on my primary ISP modem/router.  I have put the TV in the DMZ on my  primary wired ISP modem/router to avoid any firewall/port blocking issues to no avail I have even requested for a static public IP address from my ISP.

Is there any way to pull logs directly from the TV via SSH or something? BTW I also got +20 years tech experience but this is just mind boggling & highly frustrating!!

Well, besides the obvious like unplug the netwerk cable or switch it out, there could be a bad connector etc. Also unplugging and powering down are two different things. I’m pretty dumb but maybe there could possibly be enough power to keep the settings, ie:standby power? Perhaps? I would still unplug for 5-10 minutes just to be double sure and while you’re at it swap your netwerk cable out or at least check the fittings/connectors. Good luck!!

Finally this issue is solved for me, for resolution go through the below lines and follow:

I was frustrated for months with similar issue and blamed the ISP for the issue as certain preinstalled apps like youtube etc. worked fine, but LG content store was just not reachable. I had a Linksys E900 wireless router. To my surprise, changing my router made the content store reachable. With this I finally concluded it was my router that was the culprit and not LG or my ISP. I then factory reset my router settings, but it didn't work. What really worked for me was a setting on my router known as MTU (Maximum Transmission Unit Size of Data Packet). It was on Auto Mode and showed a value 1480. I then changed this value to manual mode and with a value 1470. Saved settings, restarted router and TADA it worked. Hope changing MTU size for you guys solves your problem as well. For Linksys routers this setting is under Basis Setup -> Setup Tab. The same setting for your make router if not linksys will be elsewhere, refer to the user guide of your manufacturer for more assistance on tweaking this setting.

All the best Guys!!!

      [Check out the previous episode of the 2021 Tech Trends series ]
      The third and final installment of Beyond News’ 2021 Tech Trends series focuses on how LG products can make working and entertaining at home more enjoyable and fulfilling.
      Given the environment the world now finds itself in, devices and gadgets that offer better at-home productivity and entertainment solutions loomed large at this year’s CES. The biggest names in consumer tech offered up a multitude of innovations in their virtual showrooms geared toward making life better for the millions who now work and play primarily within the confines of their homes.
      As a consumer electronics company, LG has always had its finger on the pulse of what customers want and need. With its latest innovations in monitors, laptops and projectors, LG is helping consumers optimize their lives at home, whether they’re partaking in a marathon video conference call, wrapping up a class project, mashing the keys of their favorite MMORPG or kicking back with a blockbuster movie or bingeworthy show.

      A popular upgrade for working at home is a bigger monitor. LG UltraWide Monitor offers the best of two worlds, with an expansive 40-inch curved screen that displays more information so you can be even more productive, while also delivering a truly cinematic viewing experience once the work day is done. Boasting a Nano IPS display with 5K2K UltraWide (5,120 x 2,160) resolution and 21:9 aspect ratio, this multitasking powerhouse boasts 33 percent more screen real estate than a 16:9 aspect ratio sized monitor with picture quality that makes every movie and video more immersive to watch.

      While also ideal for getting work done, LG UltraGear gaming monitors really excel when there is some serious fun to be had, with its blazing speed, sharp and smooth image quality, futuristic design, and a multitude of gaming-specific features. LG’s UltraGear series offer an ultra-fast Nano IPS 1 millisecond Gray-to-Gray (GTG) response time and reduced input latency, ensuring seamless visuals and gameplay around. Most importantly, minimal screen-tearing and stuttering makes games look and feel more realistic so you can play your very best.

      For a more portable work option that can be easily transported from the living room to the dining room (and anywhere in between), one would do well to consider LG’s latest LG gram laptops. Available in 14-, 16- and 17-inch screen sizes, the 2021 gram models boast 16:10 aspect ratio displays that are perfect for laptop multitasking. Equipped with the latest Intel processors, speedy memory and responsive keyboards, LG grams deliver a performance befitting their sleek, premium designs.
      Stylish, slim and very lightweight, the 2021 LG grams feature narrower bezels that make it possible for these devices to feature screens larger than their svelte cases might indicate.

      Movie-going has been seriously curtailed in many countries due to social distancing measures. And while some might consider a TV, monitor or even a laptop adequate for movie night at home, real cinephiles would likely bristle at the prospect. LG’s new CineBeam 4K UHD Laser projector was designed for such consumers in mind, delivering an authentic movie theater-like experience that will please even ardent cinema buff.

      The advanced projector provides optimal image quality regardless of the brightness of the room, thanks to LG’s proprietary Brightness Optimizer technology. What’s more, this portable 11 kilogram unit can transform wall or ceiling into a “silver screen” so audiences will get great picture quality whether seated or lying down.

      With a wide range of choices to suit a wide variety of needs and preferences, LG’s latest innovations make it easy to work and have fun from the comforts of home.

      [Check out the first episode of the 2021 Tech Trends series .]
      This installment of Beyond News’ 2021 Tech Trends series focuses on how LG’s products are helping people stay healthier wherever they go.
      Staying healthy goes hand in hand with practicing good hygiene both inside and outside the home. And if CES 2021 is anything to go by, appliances and devices that promote better hygiene will be one of the major trends in consumer electronics this year and quite probably for the foreseeable future. Always responsive to the needs and concerns of its global customers, LG showcased several products and technologies at its virtual CES exhibit that are designed to boost hygiene and protect people’s wellbeing. Let’s take a look at some of the company’s latest health-centric innovations and how they can make life better.

      For anyone who feels that a conventional face mask just doesn’t do enough to keep them safe, or is too uncomfortable to wear on a daily basis, LG presents the revolutionary LG PuriCare Wearable Air Purifier. The innovative device uses two H13 HEPA filters to prevent up to 99 percent of harmful particles from entering the wearer’s respiratory system,1 and makes breathing easy (unlike your average face mask) with its DUAL Fans and the patented Respiratory Sensor, which syncs the fans with the user’s breathing cycle. And thanks to a design based on extensive facial analysis, the PuriCare Wearable Air Purifier also offers day-long comfort.

      The LG PuriCare Wearable is just one of the company’s growing lineup of premium air-care solutions, which also includes residential models and a handy portable option that is great for cars, cafés or even a baby’s stroller! Fast becoming a must-have item in the home and office, air purifiers can rid the indoor environment of fine dust particles and other airborne matter that can be detrimental to one’s health.

      LG PuriCare 360° Air Purifier boasts a distinctive 360-degree design and powerful fan that enables the device to send out fresh, filtered air in every direction and to all parts of the room. A great option for those who share their abode with furry friends, the LG PuriCare Pet eliminates pet-related odors up to 55 percent more effectively than the standard LG PuriCare 360° model.2 With its specialized Pet Mode, it can draw in pet hair, as well as dust and other microscopic particles as small as 0.01 micrometers in size thanks to HEPA Filter3, to help keep the home free of sneeze- and itch-inducing allergens.

      And then there is the PuriCare Mini Air Purifier, a model that provides supreme portability with a size and weight equivalent to that of a plastic, 500 milliliter bottle of water. Fitting easily on a desk, table or car seat, PuriCare Mini can refresh the user’s immediate environment for up to eight hours on a single charge and also collects dust from the air to ease allergy-related problems.4 What’s more, the Bluetooth-enabled device lets users monitor the quality of the air around them via the LG ThinQ app for smartphone.

      In conjunction with effective air purification, a high-quality vacuum cleaner is essential to creating a healthy, hygienic place to live. Making its debut at CES 2021, LG’s latest cordless stick vacuum, the CordZeroThinQ A9 Kompressor+, comes with a brand-new charging station that automatically empties the vacuum’s dustbin. This outstanding feature saves users from a messy job and prevents dust from escaping back into the environment.
      Another excellent feature of the new CordZero model is its ability to transform from vacuum to mop (and back again) with its easy-change cleaning attachments. With the Power Mop attached, LG’s multifunctional cleaning solution sucks in dust while wetting and cleaning the floor. Conveniently, water is automatically dispensed into the mop head to keep it from getting dry, thereby ensuring optimal results and minimizing fuss for the user.
       
      LG even provides a way to remove germs and bacteria as well as allergens5 from clothes while simultaneously delivering that freshly dry-cleaned look without any expensive, time-consuming trips to an actual dry cleaner. Introducing the amazing LG Styler.
      From jackets to dresses, from business shirts to pants and winter coats, LG Styler can refresh and revitalize all kinds of clothing as well as items like teddy bears and backpacks. The Styler uses LG’s TrueSteam® technology to ensure the hygiene of users’ garments, and moving hangers to shake out any unsightly wrinkles. It also has the Pants Press feature built into its door, which creates a sharp pants crease that helps users look good and frees them from the hassle of ironing.

      Assisting consumers and their loved ones to stay healthy both inside and outside the home, the latest solutions from LG deliver impressive hygiene benefits and peace of mind. And during these trying times, those are two things that can really mean a lot.
      Stay tuned for future installments of TECH TRENDS here at LG Beyond News.

      Hi everyone. I have a LG 49U67V TV. 
      I updated my internet connection to  fiber 100Mbps. My new router  uses both 2.4 & 5.0GHz frequencies. With my mobile phone I check my Internet speed with fast.com and it is 100Mbps. My TV connected also via WiFi in the same network can't reach with fast.com more than 12Mbps. What is the problem? Does my TV not support higher speeds? 
      If I change the router settings to transmit only in the 2.4GHz frequency, would something change? Would I loose speed in other devices such us my laptop and phones? 
      No can't connect via cable to the router. And I'm afraid to pay 50€ or more for a power connection 
      I tried something else. I connected my  tplink WiFi range extender and then via ethernet cable my TV to this range extender. The problem here is that also the range extender can't reach more than 15 Mbps of speed. I tried to conect my phone to the extender and the result was the same the extender did not achieve more than 15Mbps in fast.com. So the extender had also issues achieving the speed of the ne router

      Hello,
      I would like to know, if there are any cloud gaming services currently available on lg Web os? Like Google stadia, geforce now or Xbox game pass ?

      For those who get frequent WiFi connection drop-outs, I picked this bit of useful info from another forum. Note that this may well apply to many other LG models than the C9, as they often use common WiFi internal cards/modules:
      "Network/Ethernet/Wi-Fi
      Problem: C9 [or other models] will lose the wireless connection and you have to reconnect daily (but wired is stable);
      Conditions: TV is connected to a 5GHz router;
      Cause:           (1) the router may be unstable on the 5GHz band [possibly too far from router]; (2) the router has the 5GHz band set on a higher channel - over 100;
      Resolution: (1) change the TV to the 2.4GHz band
                                (2) set the channel [in the ROUTER advanced WiFi settings]!! for the 5GHz band below 100 (ex. 40-50) - [channel 36 is often OK]."

      I am in the process of moving my WiFi to a 4G carrier. I was testing the 4G modem and needed to move back to the Broadband modem for a day - I found that the BB password was not kept on the LGWEBOS TV.  Similarly when I moved back to the $G modem I had to re-enter that. This TV is the only device that I have which does not remember passwords
      Is there a way of placing a support ticket for a change to the OS
