well i got the tv to connect to my wifi last night but when I got up this morning it was disconnected again and now it wont show any of the available networks. Very frustrating.
Regarding issue with 2019 RU7100 Series dropping WiFi connection overnight, the latest update I received is that Samsung engineers are aware of this and currently analyzing cause of the issue. Will keep you posted.
We just bought a new Samsung UDH 4K TV 7 series RU710D. We have standard in home WIFI (not xFi) and use the router provided by comcast (it's probably 1-2 years old). We bought the new TV yesterday and the set up process went fine. It connected to the WIFI and we were able to use the TV's smart features (ie. Netflix, Prime Video etc). However, after turning the TV off and then on again, the connection to WIFI was lost. We reset the network settings on the TV, "forgot" the network and re-joined, re-entered the WIFI password, and it still will not connect. The only way it will connect to the WIFI is if we do a hard rest of the router. We spoke to tech support at Samsung for about 20 minutes. He manually entered a DNS sever number and changed some settings on the TV, but with no luck. He said the issue is that the TV is being blocked by the router and thus cannot connect to WIFI. He recommended we call our ISP, which is Xfinity. A tech support agent was not very helpful and reset the modem, but we still cannot connect. Using the information from our Xfinity account online, we entered our IP address, Subnet Mask, Gateway and DNS server manually in the TV's network settings. This still did not work. All these numbers just zero out. The only number that remains is the TV's MAC address. Through online reading, it seems that the issue is that the router is blocking the TV's MAC address, thus preventing us from connecting. I've read some of the following work-arounds 1.) changing the name and channel numbers of the 5Ghz and 2.5Ghz modes, 2.) using sites online to remove MAC filtering and 3.) buying our own router.
Has anyone else had this same problem? We are at our wits end and don't know what to do. I don't understand how such sophisticated equipment and internet can have such a major issue with something as simple as connecting to a WIFI network. Our phones, computers and speakers are all connected fine. We challenged the TV by connecting to a mobile hotstop on my iPhone and it worked, so I know it's not an issue with the TV. Thus it has to be an issue with our WIFI and router, and not allowing the TV to connect. However, I just don't know at this point. I have posted this same question on Xfinity's community website as well.
Please help, sincerely an exhausted Xfinity/Samsung customer.
Experiencing the exact same problem for the same smart TV. Samsung 4K UHD 7100 series. Everyday it's going off the network. My wifi is also no more getting detected while doing a smart hub test. Should I return the TV?
