The mystery -- actual upload actions remain fine (I upload large gigabyte size files for work, and its still fast, much faster than my old Comcast which was about 20mb/s) -- I can also play online games with no issues. MY laptop can connect with the wired connection and the speeds are fine.
Contacted support over the phone. Went through litany of tests, bypassing routers, checking light levels and pinging etc. they determined there was no issue on their end -- onsite tech support had the same findings. At this point I was comfortable with the idea it might be my machine/hardware/mobo -- I replaced the onboard network card with two different gigbit ethernet cards, issue remains with both. Cant load websites or videos in a timely manner, speedtests are still strange results. Tech support claims they cant help me further, and generally are confused as well. Im not convinced the low level support team knows sall that much beyond what they are taught to check for though in a line item list thats in front of them/
I cant think of anything else other than possible software conflictions/bugs -- Ive tried multiple browsers. Ive tried disabling various software on my machine such as cloud services, adobe cc, avast security etc. I cant fix the issue, im super confused and sonic will not help me. Im reaching out hoping someone has had a similar experience or some experience with hardware/software beyong my capabilities. Ive been using the service for about 6 months with no issues so far. Anyone can help?
