Re: My Gigabit Internet is HALF speed

Your downstream being in the 20’s is too high to start. Your modem shouldn’t be running through that amp. Try adding a splitter before the amp to feed the modem, or bypass the amp, see what happens. You also didn’t note your modem model.

Re: My Gigabit Internet is HALF speed

I was getting similar results, even though the line speed was tested and good. I discovered two things holding me back. First, I was connected into a gigabit PCI adapter, so I upgraded to a PCIe adapter and was getting around 450Mbps (up from 260, the rough limit of PCI).  Next, I isolated one of the shields in my antivirus, in particular the web shield, that was majorly limiting my perfomance. I disabled that (I really just need the file shield/protection) and my speeds are around 800Mbps during peak periods.
