Model: ER7206 (TL-ER7206)  
Hardware Version: V1
Firmware Version: latest

(To the admin who took down this post, why?!?!)

 

My ER-7206 constantly switches the primary WAN connection to a cable modem (300mbits, 7ms latency) from my fiber WAN connection (1gbps, 2ms latency). No matter which ports I configure them on (SFP, WAN, WAN/LAN1, etc.) the router WILL NOT stay on the fiber connection.  Even when I set things up for Backup link (Fiber primary, cable modem as back-up) it will *still* switch even though nothing is wrong with the Fiber connection.  Can tp-link please fix this?  Its a pretty ridiculous bug not to be able to set this up and have it be reliable as this is the simplest base use case for a multi-wan router.

  @ehubb,

I don't think youre post was taken down, you may have posted it to another community such as our global EN community, as they appear almost identical.

 

Since you seem to have done some troubleshooting already, have you come across anything that you think would be the cause or be causing the switch to the Cable connection?

 

Is there anything special that you have experienced with your fiber connection that may cause the router to lose WAN access? and it simply doesn't switch back?

 

Lastly, what are the details of your ONT and provider, so I can see if there are any known issues.
