Super Super Slow Internet Speeds

I had the lowerst speed internet available from Xfinity for 1 year.  Never had any issues with intenet speeds / uploads / downloads, etc.  Xfinity upgraded me to a higher plan as if they were doing me a favor.  Ever since the upgrade, i have had nothing but problems.  My internet speeds are painfully slow and my internet drops out at least 3 - 5 times per day during prime hours.  

Of course I called in and got the usual runaround / testing / boiler plate jargan.  All of sudden I might have connection issues and possible splitters in my line and possiblitiy of a bad router.  I had none of these issues when I had the slower plan.  My system worked perfect for a year without any problems.

Now I am paying for a service I am not happy with.  I am waisting time researching and troubleshooting.  I am wasting more time posting to a forum, in hopes the magic Xfinity wizard will fix my internet, but I digress. 

Come on Xfinity!
