Not getting close to gigabit speeds.

Not getting close to gigabit speeds.

Switched from Blast! 250 to Gigabit a few days ago.  First day was the only day I got close to the 960ish and that was 790Mbps.  The next 2 days it dropped to about 300-500Mbps and hasnt been much higher since.  We had a storm following that and I started receiving a crazy high amount of correctable errors.   Had a tech come out and he added a splitter outside because he said my signal was a little hot, and he put in a ticket to maintenance to correct the errors. They came out about an hour later and replaced something a block away and since then the errors have stopped but I am still not getting close to the advertised speeds with no answers as to why.   

 

I have tried connecting directly to my desktop (which far exceeds required specs), factory resetting the modem, and obviously having a tech check.  None of which has helped.
