Hello Chas m, thank you for your reply. This is something I have been thinking about also. On Sunday I went into my service supplier (Plusnet) and checked on their speed indicator. Because a single speed check may not be truly indicative I looked at the speed history for my connection with the following results: download 0.4 MB/s and upload 47kB/s. As you say, using the internet for browsing, including video, is fine - quick and responsive, but the trouble may be the uploading side.
