Slow WAN SPEED on MX67

[nikovalchanov]

I have a problem that I can't solve.
I have a Meraki mx67. I am connected to Wan 1 of the internet with a speed of 600 mb. Everything is fine for a few days and then the speed drops to 80 mb. I do not receive a notification and until I restart the router the speed is low. I thought the problem was with the provider and it I called, they replaced all my equipment but the problem remained. Is there an option to automatically restart the device?

Do the event logs show anything around when the speed drop occurs? 

What troubleshooting have you done? 

Does the Dashboard throughput match the drop you're seeing on your device?

No, you could work something out using a scheduled api call.  

But it would be better to fix the issue, maybe firmware related?

What firmware version are you running?

Hi @nikovalchanov,

What is the link negotiation speed of WAN 1? If you hover around the WAN port it will show you the current speed. If the negotiation is downshifted to 100 Mbps for some reason you might see a drop in throughput, so I would start with tshooting Layer 1 first. Also, questions from @double_virgule will help isolate the issue further.
