Connectivity option with quicker speeds compared to traditional Ethernet connections
Connectivity option with quicker speeds compared to traditional Ethernet connections
I relocated into a new residence and upgraded my internet via AT&T, offering speeds of 300 Mbps upstream and 300 Mbps downstream. I linked my mesh network (https://www.newegg.com/tp-link-deco-x60-...6ZPBWF7445) to it. Performed a brief speed test on my phone to the mesh and achieved 320 Mbps upload, 380 Mbps download. I was pleased until I ran a test on my desktop, which showed only 96 Mbps upload and 7 Mbps download. This setup is connected directly to the AT&T modem/router combo. I attempted to route it through the mesh’s LAN port, but performance remained unchanged. Even when manually setting both Ethernet ports on the router to full duplex at 1 Gbps, there was no improvement. My NAS device, also plugged into the same router, managed to transfer files at up to 120 MB/s (full 1 GB).
The same cable appears consistently across all tests. This makes it the most likely cause.
Open devmgmt.msc to identify the network interface card in use. Avoid using Windows driver updater; instead, visit the vendor’s site for the latest drivers. One client experienced crashes when drivers exceeded 800Mbps. If the device isn’t an Intel/Realtek NIC, verify other manufacturer tools and disable or remove them. Also dealt with a client whose "Killer" NIC limited performance to about 5-10Mbps, effectively throttling traffic until the software was turned off.
I tested it on my laptop and it functions well with a wired link. Likely the issue is with Windows 7.
