Uses Asus RT-N15U gigabit LAN only delivering 150 Mbit per second
Hi everyone, I'm facing some problems with my Asus RT-N15U router. It's quite an old model, bought around 2014. About two months ago, when I got home, the Wi-Fi worked fine in the morning but later tried to reconnect using my credentials. The ISP timed out. I’m on a Broadband PPPoE connection with a 1 Gbit fiber port. After resetting the router, everything seemed normal. Now, on the gigabit LAN port, I'm only getting about 150 Mbit. I don’t know why this is happening or if it’s related to the port itself. I’ve checked other ports and rebooted the router several times, but nothing changed. My motherboard is an Asus ROG Strix X570-E Gaming, using the gigabit port with Intel I211. I also tried connecting directly to the endpoint device, which worked perfectly. Could anyone help figure out what’s going on? Thanks for any advice!
Have you considered a Cat5e or faster Ethernet cable? Given the device launched in 2011 featuring a 550MHz processor, 64MB of memory, 8MB of flash storage, and WiFi 4, using it on a gigabit fiber connection seems unusual. It’s likely your RT-N15U struggles to keep up due to its limited CPU speed and insufficient RAM. If you needed a reason to upgrade, that’s the case.
It includes NAT acceleration (Broadcom FastNAT) that might have been turned off, though I'm skeptical it could handle Gigabit speeds even without it. Disabling it would likely cause issues, especially with a PPPoE connection that would struggle under the CPU load.
Hello everyone, regarding the new Cat5e cable, I didn’t switch to another one because I’ve already checked the issue with the optical terminal or endpoint device—it works perfectly. For testing internet speeds, I haven’t measured my local connection; I only used speedtest.net and my own speed tester (also via speedtest.net). I have an extra Asus RT-N56 cable on hand and could easily replace the N15 whenever needed. This might be a suitable upgrade. I’ll keep an eye out for Wi-Fi 6 or even Wi-Fi 7 options. The problem with my N15U is puzzling—its performance dropped suddenly, even though it was functioning well two months prior (it once handled over 95 MB/s and sometimes more than 100 from the ex-origin/EA app). Thanks a lot for your input; it’s really appreciated.
