I was recently on Vivid 350 and constantly got this speed. I recently (2 weeks ago) changed my package to VVIP with Vivid 500. Initially I was getting above 500mbit and was very happy. I have been away from home and when I returned a few days ago I checked the speed again, I am no longer getting 500mbit. In fact its not what I would consider close enough to ignore. I know its not a guaranteed speed at peak times so I intentionally tested the speed at different times. Breakfast time, Lunch time, Dinner time, Evening and 3.30am. At none of these times did i get a maintained speed close to 500mbit. The speed peaks at 500mbit for a second then settles out and the average speed over the course of the speed check is not close. I have not changed my setup since installation. My WiFi is secure. I am using a wired Ethernet connection. No other devices are downloading or streaming. I have tried Edge, Opera, Chrome and IE browsers. I have tried various speed checkers including Ookla (as recommended and used by the engineer), Sam Knows (recommended by Which?), Fast.com (recommended by Netflix) and a few others. I have the latest windows updates, latest drivers. I am using a speed test server closest to my home, for example, the server used with Ookla is 6 miles away. I have also tried servers in other locations. I worked as an IT Engineer for 23 years so I do know enough to know that this is not a problem with my equipment. I am getting speeds between 250 mbits and 430mbits, No faster. I have screen shots of the speeds. I would appreciate it if someone can contact me regarding this and look into this for me, I refuse to pay £140 a month for speeds that are 20% to 30% slower than advertised and listed in my package. Thanks.
I have just checked the speeds again and three times in a row i received speeds of 550mbit plus so for now I will put this on hold, i have to go out anyway and away for a few days, thanks for the reply.
