Do you have 1609 gateway firmware update yet and how is it working for you?

I have been having terrible speed issues for almost a month and I don't know if it's the 1609 update but it was around that time things started getting bad. I've spent so much time on this and the only thing that got my speeds up to normal was when I took the sim from the LTE model they sent me to try and put it in the trashcan, my speeds instantly went back to normal. 2 days later my speeds are back to 5mbps. My speeds when I first got this service (for 5 months) were around 180mbps down so I know good speeds are possible. Has anyone found a fix for this? These are now my normal speeds.
