Hi there, I went to look in the settings, and found this but the field is blank. I've been using Wi-Fi since, but when connected via cable to the CBR40 I used the first of the four ports. (Though I tested on others.) I hope this info helps, not sure where else to look.

Do the wan statistics page when a device is plugged into the port

Here's the WAN info from the statistics:

Get the whole wan/lan. Trying to find out what the lan is showing up connected at while a device is plugged in. 

Thanks for being so patient, this is all new to me!

What ever is pluged into LAN port 1 is only connecting at 100Mpbs and not at 1000Mpbs. 

try replacing the cable with at least a cat 6 cable. And try it on different ports to see if its related to the port. 

Thanks for your help, I checked that I'm using a CAT6 cable and also tried different ports. Still the same.

when you switch ports, does the other port switch to 100mbps connection? 

do any devices connect at gigabit speeds under the statistics page?
