Sharp TV LC-43LB481U disconnecting from wifi

I've had my Sharp LC-43LB481U TV for about 10 months and have had no issues, but lately, it frequently freezes and says that there is no Internet connection -- it is disconnecting itself from my Wifi as when this happens, I verify that other devices on the same network, SSID, band are still connected without error.  I either unplug the TV or restart it from within the settings menu and it reconnects and works ok for a day or so.  The TV software (Roku?) is up to date, and I have checked Sharp's support site and it says there is no firmware update.

 

I see this issue has been reported in various web sources over the years, but no resolutions.  Any ideas?

Re: Sharp TV LC-43LB481U disconnecting from wifi

Exactly the same story here. All other devices are fine, no new technology in the house to cause interference. Daily the tv drops the internet connection and can’t find it until I unplug the tv (just the tv... not the router/modem/computer/anything else) and plug it back in again. Just turning the tv off is not enough - it needs to be unplugged. The router is 15 feet away from the tv and all other devices are connected and stay connected so I don’t want to start monkeying with my router settings.  Anyone have a solution for this close-enough-to-new tv’s annoying problem?

Greetings, kabboroo –

 

Welcome to our community! Thank you for sharing your concerns with your 43” Sharp TV with us. It would drive me bonkers if my Sharp the ethernet connection regularly like that.

 

It appears that you’ve verified this as a possible known issue for this particular model. I’d highly recommend reaching out to Sharp to see how they may be able to assist you further with a long term solution. If you had purchased the TV within the last year they should be able to assist you further under your manufacturer’s warranty. You can give Sharp a call at (800) 237-4277.

Re: Sharp TV LC-43LB481U disconnecting from wifi

I have reached out to both Sharp and Best Buy and discovered that this model is a co-branded model or something - basically Sharp makes it specifically for Best Buy and so Best Buy handles the warranty on it.  They have a tech coming out next week to check out the TV...so help me if he/she tries to say there's nothing wrong with it! Tonight instead of just disconnecting, it shut itself off twice! 

 

I always used to buy Hitachi TVs and they'd last literally over a decade without any problems...guess what I'm buying next time around?

I've been having the same issue! I've had the tv for approximately the same amount of time and my router is right next to the unit. Please keep us updated because I'd love to know the resolution. If there is none, I guess my option is to never purchase a Sharp TV from Best Buy again!

Re: Sharp TV LC-43LB481U disconnecting from wifi

The TV is still under warranty - though it is a Sharp TV, it is a co-branded model with Best Buy and Best Buy handles the warranty.  They sent a Geek Squad tech out to swap the wifi card - we'll see.
