Slow wired speeds - brand new flint 3

Hey, I've bought flint 3 and I have subpar wired speeds.
When connected directly modem to PC it's about 700Mb/s.
When through flint 3 it's about 300Mb/s. I didn't change any settings, flint 3 is on newest FW, both cables are 1000Mb/s.
Rebooting with cables unplugged did not help.

Hi,

  1. Please try to change the Flint3 Ethernet 2 to WAN mode and Ethernet 1 to LAN (reverse each other) and check again.

  2. How about the speed of Flint3 wireless network?

  3. Try to enable IPv6 function of Flint3

  4. Disable hardware acceleration (I saw you mentioned in reddit, ignore this)

  5. SSH to router, and execute:

opkg update
opkg install python3-speedtest-cli
speedtest-cli
  1. Flint3 switches to AP mode, PC wired connection to LAN port, how about the wired speed of PC?

Hi @bruce. I’m having the same issue as the OP. With all default configurations I get approx. 150 Mbps down on wired and wireless, but if I plug my PC directly into my modem I get my full speed of 300 Mbps. I tried the things you suggest and here’s the results:

  • Changing Ethernet2 to WAN and Ethernet1 to LAN: Flint3 was not even able to connect to the internet through my modem.
  • Flint 3 wireless speed is the same as wired
  • Enable IPv6: no change to speeds
  • Disable hardware acceleration: no change to speeds
  • speedtest-cli via SSH: 85 Mbps… even worse than on my PC through my browser
  • Switch Flint 3 to AP mode: 300 Mbps (full speed) through a wired connection to my PC but I cannot connect to WiFi at all

My Flint 3 is on firmware v. 4.8.3. My PC has a gigabit NIC (Intel 1219-V). All cables & patch panels in my house are Cat 6.

Any assistance you can provide would be greatly appreciated. Thanks.
