If the mini is connected on the 5GHz signal try connecting on the 2.4GHz signal, it's slower but stronger.
If you haven't got 5G and 2.4G bands then you need to split your Wi-Fi network, instructions on how to do that are in link below, when you have selected Advanced Settings you will also need to select Wireless, Wireless Signal and click on Disable Channel Optimization at the bottom then click on Apply Changes.
Thanks roy247. I use the Hub 3 as a modem and TP Link Deco M9s to distribute around the house. Signal strength is excellent but I'll try turning off the 5GHz. Appreciate your help
Hi @benno17 thanks for posting and welcome back to our community.
Sorry to hear your recordings on your TV 360 buffer when accessing via your TV 360 mini. And for any inconvenience this may be causing you. Have you had opportunity to test the advice offered from roy247? If so, how are things going?
Yes I have tested the suggestion made by roy247 but without success. Interestingly the mini upstairs and thus farther away does not have the buffering issue
