Speed increase but speed unstable

Only been 2 days but I used to get a solid 160 meg, rarely down to about 130 in peak hours.

Since the upgrade its varying between 60-90 most of the time, when its working ok its more like 120 or so speedtests say but downloads are lower except at that rare time its almost at full speed.

Just wondering if it will get any better?

I can give stats of told how or needed.

What part of the country are you in? The speed upgrades seem to be coming before the backend capacity is increased, so you maybe seeing some issues with the utilization in your area.

I live Hamilton Lanarkshire.

Speeds are getting worse, it is hard to see if its just busy as during the night and around lunchtime it seems to almost max out but even then not constant, at most it fluctuates between 40-80 often 60 average.

Before was a almost solid 160 with a few dips to about 135 for a few minutes now and again but rarely lower.
