I have been having constant connection issues when playing online gaming on my PC. I use a Ethernet connection, my ping bounces upto 300+ constantly, I get non stop packet loss, lag and rubber banding issue. I am on the M200 package and pay a lot of money and its getting frustrating not being able to play online games.
I have been having the exact same issue recently!! it started after Vrigin said they was doing some "Performance" work in the area.... -_-.... at that time i had no internet for a week, and now is frustratingly bad with all the things you mentioned. i have over 380mb download and 26 upload. before the work done by them i had the same download and about 45 upload! they keep sending me engineers out to no avail as they keep telling me they are gonna do a re-wire from the outside box to my house. but only the 5th engineer that came out actuall booked that in for me. if its not sorted soon ill be leaving thats for sure
