RAX20 LAN ports are capped at 100mbs
Hello, my router (info pasted below) does not reliably give me full speed on the LAN ports specifically. I have 900+mb/s to the modem, and if I plug the ethernet cable (cat6) directly into the modem I get my full plan download speed of 500mb/s. If I then route the ethernet cable from modem > router, and plug my computer into the router I'll get 500mb/s once, and then 100mb/s afterwards. If I power cycle the router, I'll get 500mb/s again but then it reverts to 100mb/s. I've tried all 4 ports and the behavior is the same.

Be sure the ethernet drivers are up to date as well.
The RAX only supports up to 1Gb connection rates so you might set a manual connection rate on the adapter for 1Gb only.Please mark your thread as solved so others will know. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
