New 4331 very slow and intermittent internet

[Jkad432]

Hello all,

 replaced a 2900 router with a new 4331 isr. Worked great for 5 days and then Became increasingly unresponsive. Reset to factory and started from scratch again and it works (local network works great) seeing some packet loss pinging external ip from an external network and it’s very slow loading web pages, I currently have the trial boost license. I have gotten the notice that I was approaching the license cap one time. Negotiation is set to auto.

any ideas what would be causing such slow speeds

Potential speed/duplex mismatch error.

This is a copper port.  The port configuration should be auto speed/auto duplex.
