We are sorry to hear you have been experiencing issues with the speeds of your STB and buttons on your remote jamming. We would like to find out some more information in regards to the issue with your box. Are you able to confirm;
Which box you currently have?
How is the box connected (cable or WiFi)?
Do you have any other boxes in the property? If so are you experiencing this issue with any others?
Are you only experiencing speed problems when using apps?
Apps like Netflix and YouTube are slow to load up and the remote control buttons jam or speed across/down. Certain films like Bandersnatch could not load, I wasn’t bothered then, but now it just jams regularly when restarting and sometimes it just switches off. I only have this box. Internet speed seems fine.
