I've owned my Roku Streambar since December 2020, in that time it's been great - up until now...
A week ago I went to stream something on it and it was unresponsive.
I checked the network connection and it was excellent (as it has been throughout my protracted efforts).
I have reset the Streambar back to box-new settings to no avail; I've done the same with my router (Huawei B535 232) - still no joy.
I understand that the Streambar is dual-band, even so I've tried it at 2.4 GHz, 5 GHz or both. I've tried changing the Wi-Fi channels but still nothing... and the connection remains excellent.
My two other devices, a recent iPhone and an ancient Samsung laptop have no such issues with the Wi-Fi, regardless of GHz or channel.
I did succeed in connecting my iPhone's hotspot to the Streambar and it streamed as it should, though with a 4GB monthly allowance that's not practical!
I should be writing my degree modules and have already spent at least six hours trying to fix this (Roku support didn't help). I just want to enjoy a glass of wine and an hour's viewing at the end of the day.
If it helps, I'm in the UK.
