I'm getting a solid 1Gbps from my Wi-Fi, but my TP-Link powerline Ethernet adapter is only providing around 120Mbps. Since my adapter is supposed to support 1Gbps, I'm wondering if there's a way to achieve higher speeds over Ethernet, or if this performance is typical?

Honestly, it’s pretty normal to see that kind of drop with powerline adapters. They're more of a last-resort solution for connectivity. Have you considered using MOCA adapters? They can make use of coaxial cables in your walls and usually provide much better performance for Ethernet.
Yeah, powerline adapters are definitely hit or miss! They might not give you the speeds you're hoping for, especially depending on your house layout and electrical systems. If you need solid speed, using a direct Cat5e or Cat6 cable is the way to go.
Powerline adapters can be pretty unreliable because their performance heavily depends on your home's electrical wiring, which you can’t really change. If you're looking for a better connection, I’d suggest considering more Wi-Fi extenders or switching to a mesh network. They can offer more consistent speeds compared to powerline adapters.
