Flint 2 Slow and unstable internet

I am using a Flint 2 router as my main router. It is connected to an xfinity modem/router that is in bridge mode. I tried the router in most of the firmwares, v4.7.0 and the new beta one, but I was having huge internet issues, getting speeds less than 50mb/s via ethernet and wifi, and disconnecting issues.

I upgraded my firmware to the luci openwrt 24.10.0, and the ethernet speeds are much better, and i am not disconnecting anymore, but it is very unstable. I will be getting 800mb/s sometimes, 200 mb/s other times, and 40mb/s sometimes. It is also noticeable during gaming. Did anyone have issues like this, and does anyone know how I can fix this issue? could it be a setting I can change in openwrt? So far, I tried enabling software offloading, but it didnt do anything.

Hello,

Please PM me the issue syslog, to check if the WAN cable disconnects due to the 2.5Gbps network port compatibility.

When wireless is unstable, please try to test wireless with another client, for example an iPhone replaced with Android or laptop.

Thanks for your reply. I sent you the syslog. For more information, I am using ethernet. I noticed that when I restart my router, the internet speed gets back to normal (900 mb/s), but after around 3 minutes, it gets back to around 300 mb/s. I have my router connected to the isp modem (which is in bridge mode). I tried changing the dns server, restarting, resetting, enabled SQM, hardware acceleration, etc. Could the problem be something to do with the interface devices? LAN is set for br-lan ~ WAN is set for eth1 ~ wan6 is set for eth1. Do I have to adjust anything in there for the internet to be more normal and consistent?

Hello,

Is this the speedtest.net test result on wireless client?

When the wireless drops to 300Mbps, is there 900Mbps in wired?

  1. Please try uboot to flash GL firmware, op24 and stable firmware both ok.

  2. I saw in the log the LAN3 port re-connected. Did you manage it manually yourself?

  3. Please export the syslog logread.tar file, and PM me again.
