Hey Kjones22 - I have the same issue for the past month or so. The internet works majority of the time, but at specific times of the day, I get very low upload speeds. I'm a gamer, so it is very aggrevating when you get booted from you game every 15 mins or so because of the internet. Back in June, between 2pm and 4pm the internet would be sporadic, this month it is now 9pm to midnight or later. Help Desk personnel just want to send restarts and some techs seem they are being inconvenienced because it's just before lunch or time to go home. After losing services for 4 days (after a lightning storm) a tech did come out and get me back online, but the problems still persist. Just dont know what to do anymore. Paying big bucks each month for sub-par service is getting old. Hope your situation improves.
Well you could always take a look at the troubleshooting here:
