Slow wired connection to Raspberry Pi


  • Hi,

    I just got my AmpliFi HD Router and it's been very nice so far (a day). However, I noticed that wired connection to my Raspberry Pi (3B model) is significantly slower than with my old Netgear router.

    This is the speed with AmpliFi

    pi@rpi ~ %  speedtest
    Retrieving speedtest.net configuration...
    Retrieving speedtest.net server list...
    Selecting best server based on ping... 17.788 ms
    Testing download speed.....
    Download: 36.65 Mbit/s     
    Testing upload speed.......
    Upload: 11.68 Mbit/s
    

    And this is the speed with the old router.

    pi@rpi ~ %  speedtest
    Retrieving speedtest.net configuration...
    Retrieving speedtest.net server list...
    Selecting best server based on ping... 70.054 ms
    Testing download speed.....
    Download: 92.87 Mbit/s
    Testing upload speed.......
    Upload: 11.65 Mbit/s
    

    I have tried to use ethernet with my laptop on that same port, but laptop still can do ~120Mbps using either fast.com, or speedtest.net (that's also my Internet speed), so the issue is narrowed down to the router and the Raspberry Pi in particular. I also tried turning on Hardware NAT, and it didn't help.

    Can some one please shed some light over this issue? It's very strange to me.

    Thanks!
