    Hi,

    I have been using the TCL U50S7906 TV for several years, from the very beginning I have been using smart TV by connecting to the Internet via WiFi. A few days ago, the TV suddenly lost internet access. I am using a FRITZ!Box 7560 router.

    Resetting the TV to factory settings and restarting the router did not help.
    I did not factory reset the router, but I also never changed anything in it.

    The TV connects to the internet when I share the internet with my mobile phone.
    I checked that the TV has up-to-date software.

    Maybe someone had a similar problem with another TV and can help?

    Regards,
    obliterate

    Hi,

    Does anyone have an idea what else I could try.
    Since the last post I've tried the next things that didn't help:
    - reset the router to factory settings,
    - set the DNS servers in the router to google servers,
    - I changed the WIFI network channel to one that no other network in the area has. Here I use the inSSIDer program. I don't know exactly what to look for when choosing a channel. I tried to make other channels from neighboring networks have the most distant channel numbers.

    I'm out of ideas for now.

    Regards,

    I would contact the manufacturers - they usually have hotlines which are really helpful sometimes

    A bit of a dig, but I have the same on the U49S7606DS model. Maybe someone had an idea? For me, DVB-T started to tear, less on HD channels and more on SD.

    Switched to manual no effect. In addition, it works on ap from the phone just like its predecessors. It also works if I create a new SSID on the same AP, but unfortunately only for the first start of netflix ...

    Have you solved the problem? I've had the same problem for 4 days. TV Smart Samsung UE40KU6000, Huawei E 5576 mobile router. All possible resets carried out, including remote from Samsung. Manually set network, the operator claims that there is no problem on his part. The TV connects to the network but not to the internet. On another network there is no problem, the internet on other devices works. I have no idea what to do next, everything works, and I have a problem...

    Hello, this is a different TV TCL has a different system
    Try to check the time zone, time and date, is it set correctly, change the network name to a different one and the password, the router probably does not have a 5GHz frequency, if it is, change it to 2.4GHz or from the phone, how do you share the network, does it work?

    Thanks for the tips.
    A miracle happened! In desperation, I disconnected the TV completely in the router app and after a while I tried to pair them again. As if nothing had happened, the internet started working.
    Samsung should pay my salary 😁

    I had the same problem and noticed that others wrote about changing the date and time. I don`t know what it is, but it helped.

    Date and time, it worked. I struggled for 7 hours with the TCL 50C645. Thanks.

    The TCL TV did not automatically switch to daylight saving time. The effect, as written earlier in this thread, includes: Live network streams did not work. The archival ones worked. The WiFi connection status showed "limited connection". Setting the time zone to GMT+2, i.e. Central European summer, helped
