I am having trouble connecting my Peplink 30 to a Adtran Netvanta 3430. When I connect the 3430 to two different laptops or my NetGear router I get the full speed of my internet connection, 10Mbit up and 10MBbit down. When I connection it to my Peplink 30 I get various bad results, sometimes I get .5 Mbit down but 10 Mbit up, sometimes the opposite, sometime 4 Mbit down and 10 Mbit up, etc. Also, sometimes I get the WAN DNS health check failed message. I have tried many different cables, cross over cables, etc, different combinations of port speed settings, and have been unable to find any solution. I tried this on 5.3.12 and 5.4.6. I posted a related problem with not being able to change the port settings on 5.4.6 on a separate thread.
When I connect the 3430 to my NetGear router I see that it negotiates a port speed of 100Mbit Half. Could the Peplink 30 be having trouble with this kind of port connection? (Note I tried forcing the peplink port speed to this speed with no change).
One thing I have noticed is that the link LED on the 3430 is always green when connected to the peplink independent of the port speed I set it to. When the 3430 is connected to the NetGear router the link LED on the 3430 changes to orange. It looks like the peplink is not actually changing its port speeds…
Does anyone have any advice on how to handle this?
