Fortunately, Virgin has been on our street for years. Just switched to a new company called GRAIN now I have similar issues.
Google assistant went south and a number of sites are hard to access. Even though we are on a 1g up and down. Watching a steaming service is touch and go... The sky box cannot get netflix, but the TV does Huh? Go figure.. Prime video and disney work great... I wish I knew networking, there is definately a change in some protocol or other.. It all worked seamlessly on Virgin but they went far too expensive.
