Upgraded internet but now getting slower speeds than before
Yesterday I upgraded my speed from 600 to 1200. Before the upgrade O was averaging between 600-700 mbps, and now averaging 200-250ish. I've talked to multiple customer service reps with no luck. I've restarted the gateways several time in the 2 days and no luck. I've tested the wifi using 4 different devices all with roughly the same slower speeds. Any suggestions?

What equipment are you using? Rented gateway, own modem + router, or own combo cable modem/WiFi router? What models?
If you're using equipment that isn't approved for 1200 you can get results like this. Comcast will only approve modems and combo units that have a 2.5Gb ethernet port for 1200. If your device isn't approved it won't be configured correctly for 1200 and will basically end up in limp mode. If you're using a DOCSIS 3.1 device that only has 1Gb ethernet ports and is approved for the 900 plan a 1200 plan likely won't get you 900.
If you're renting equipment I'd go ahead and have them swap out your gateway. It's pretty much the first thing Comcast wants to try.
This kind of thing can happen with equipment that supports 1200. I have a buggy MikroTik RB5009 router that did exactly what you're describing when I upgraded from 600 to 1200. 1Gb devices connected through the 10Gb port on the router (with a switch or two in between) would get ~250, so I had to rearrange my network a bit so all 1Gb or slower devices were connected through a 1Gb port on the RB5009. Now I get ~1400 on 2.5Gb and 10Gb hosts and ~900 on 1Gb hosts. WiFi maybe 600, but that's because of my cheap APs & all my WiFi clients being WiFi5/802.11ac. I'm guessing this isn't your particular problem, but things like this can happen. On that note, I should check for a RouterOS and firmware upgrade. Maybe MikroTik will figure out how to fix it.
