I have 300mbps dl and 30 upload, but im only getting 4-7 upload speeds on my pc. my phone runs at the right amount so I bought a new NIC thinking it could be that, but im still only getting 4-7mbps upload. Could this be related to another hardware or software issue that im not aware of?
(Some assume that given a 30 Mbps upload speed advertised thru ISP that all servers worldwide will take data at those speeds, while they often cannot, as serving thousands of customers causes bandwidth caps to be invoked)
If you have a second machine in the house copy files between the devices. Best if both were on ethernet but it might show something even on wifi.
Watch the resource monitor tab for network. Be aware some values are in BYTES/sec and other are in BITS. What you want to see is if you get faster upload rates on your lan. It should help to determine what in your machine may be slowing it down.
