Samsung Smart TV not connected to Xfinity Wifi
My Samsung Smart TV won’t connect to my Xfinity Wifi. I just moved and have Xfinity Wifi only. The Samsung TV sees the wifi but won’t connect to it.. and yes, the password is correct. I’ve gone through a complete reset of the Samsung TV with Samsung Cust Suppt and still not working. Any advice from Xfinity forums? All other smart devices have connected fine. I’m at a loss.

This depends on the specific model of TV, and the radio in it. Look up the model number of the TV and see what WiFi standards it can speak. It also depends the specific model gateway you are using.
More on WiFi Standards: https://www.lifewire.com/wireless-standards-802-11a-802-11b-g-n-and-802-11ac-816553
Can you change WiFi "standards" on Xfinity gear? Maybe, with the phone app. Perhaps you can downshift to 802.11 b/g/n (Separate 2.4 and 5G signals):
https://www.xfinity.com/support/articles/xfi-advanced-settings Results are mixed. You can't change settings if you have Xfinity pods attached.

Another real common one -- if your TV and gateway are speaking the same WiFi standard, is the authentication. Another little default setting arbitrarily decided for you on newer Xfinity gateways is the encryption. Default is now WPA3. Many devices can't do that and only have WPA2 capability.
Both are still considered secure at this time, but the migration path is there. Newer gear you buy will use WPA3, but you'll have a mix for quite some time. Years likely, unless an exploit is uncovered like with WEP.
I don't know if you can change WPA2/WPA3 by logging into the gateways these days. It probably has to be set from the phone app now too. Look for Wireless Security settings.
This is why specific model numbers become important. Radios and what you are trying to connect to. Both have to agree on what is acceptable to negotiate communication.

Is there a fix for this yet? My samsung 7 series no longer connects to my xfinity box. I have had 4 coversations with xfinity support and no fix yet. I suspect concadt broke something here and wont admit it.

I recently started having this same issue. Every device connects to Wifi except my Samsung TV. I spent hours on the phone with Xfinity and Samsung and everyone is clueless. My TV says it’s connected to the internet but when I go to Any App on the TV I get an error message stating wifi is unstable or just an error message. Wifi on my TV was working fine until I recently upgraded my Xfinity plan. At this point I’m going to cancel the plan and go back to my internet only plan. I’ve had Xfinity for years and have had this TV for a year and half with no problems. It’s crazy that no one at Xfinity knows what to do. It’s so annoying and I am beyond frustrated.

If you have a 4K television, trying to watch 4k on You Tube, etc. is asking a lot for Wi-Fi only. Many devices can cause RF interference and block the signal. The tv needs to be connect to a gateway with an ethernet cable.
