I have a quick update.
My setup before netduma was using the 2 in 1 modem/router from comcast.
My setup after netduma is with the netduma as the router, with comcast 2in1 as the modem.
Before netduma, I had never had problems with my upload speed slowing down or being capped.
After netduma, My upload speed keeps capping at 2mb/s until I factory reset my netduma and do all of the settings again.
I thought it could have been comcasts equipment that had been messing up, but it wasn't until after I did a normal reset on the comcast modem like last time to check if it was the problem, I was still capped. Then I factory reset the netduma and ran through the proper setup (like last time), and my speeds returned again.
all signs are pointing to the netduma right now, I'm not an expert or anything but if factory resetting to get my speeds back is the only solution how isn't it the netduma?
