Why Is My Internet Upload Speed Stuck at 5 Mbps?

Asked by TechWizard99
I'm having some issues with my Verizon internet gateway. I'm on a gigabit connection, but my upload speeds are consistently around 5 Mbps, sometimes hitting 6 Mbps on my phone. My setup includes a Killer E2600 gigabit network switch, and I've even removed the problematic drivers from it. The connection quality at times is pretty poor, ranging from -90 to -110, which I suspect is due to the area. Downloads are around 80 Mbps, and I've already played with the settings in my network portal, ensuring we're on full duplex. I'm looking for tips to boost my upload speeds while waiting for Verizon to check the router. My fiancé and I are trying to game together, and we'd love to get that sorted out!

You really won't be able to achieve what you want on a 5G connection. It’s likely you'll need to upgrade to a more reliable internet package from a provider that offers cable or fiber to get better upload speeds.

First off, is your Verizon plan actually intended for gigabit speeds? Also, check what your PC's network adapter port speed is. If the router supports 1 Gbps but your adapter only negotiates 100 Mbps, you'll be limited that way. Mismatched speeds can stem from bad Ethernet cables or issues with the LAN ports or NIC card. Have you restarted your router yet? If it’s coaxial, make sure that connection is tight. Too many variables here, but those steps should be a start!

Honestly, if you’re relying on a 5G signal, don’t expect stellar upload speeds. Wired connections generally outperform cellular for gaming. Maybe look into local wired options for a better experience?
