I just replace my old router with an ASUS RT-N66U. The router says it supports up to 450Mbit/s on 2.4GHz and 5GHz. I know I cannot expect to exactly reach that speed because of overhead and interference, but I am not getting speeds even remotely close to that.
My computer has a TP-LINK TL-WDN4800 PCIe adapter which I bought in the past few months. I used the program
iperf as suggested by some other posts on superuser. On my PC, I run the command
iperf -c 192.168.1.7, and on an old headless PC connected to the router via ethernet, I ran
After doing a couple of runs, I get anywhere between 40Mbit/s and 50Mbit/s. I have a long ethernet cord that I used to connect my PC and router, and did the same test again. I got a solid 94.1Mbit/s to my headless PC.
I haven't seen any examples of what speeds other people get on their home networks. However, I feel like both the wireless and the wired speeds to my server are really slow. Is it possible I got a bad router? Is some other factor causing both tests to run slow? What can I do to find the cause of the slow speeds and fix it?
As suggested in the comments by Spiff, I was able to determine the speed of my headless PC's built-in ethernet port. It is running Ubuntu server, and after installing the package I used the command
ethtool eth0, and determined that the max speed it supports is 100Mbit/s (the
100baseT/Half 100baseT/Full standards). My PC with the wireless adapter supports
I can't say I am surprised about the server, it is a VERY old computer. So I should probably purchase a PCI/PCIe gigabit ethernet port. However, that doesn't explain why the wireless speeds are so low.
I will update this post when I find a system with a gigabit ethernet port to test
