Drastically Slower Speed Running Starlink through Peplink Router

I have a performance dish on the roof of our RV. I have a Max BR1 mini that I use to integrate starlink and cellular into one connection. I am using all starlink cables and all are new. When I run a Speedtest with the starlink running through the peplink router, my speeds are in the 20-30 mbps. When I install the starlink router and don’t use the peplink router my speeds are in the 300 mbps range. I know the peplink will slow down the connection some, but this much? What can I check or are there settings I need to verify?

A peplink should NOT slow down a starlink connection. Please contact the partner you purchased from, as they likely know your scenario best. Otherwise, open a support ticket. One possibility is that the ethernet is not negotiating properly.

I have been working with them, but they don’t seem to know what to do. They tell me to check and make sure my cables are good. I do know that when I am running a starlink speed test it is different than the one I run on my phone through the peplink. But I cannot imagine it would be that significant.

Let me ask a different question. What is the best way (parts required I know) to connect from the data port on the performance dish power brick to the WAN port on the peplink router. I can’t use the starlink cord because it is way too long. So I picked up a shorter cord from Stargear (I think).

Why are you worried about length of the oem cable? Coil up the extra. Process of elimination. Swap in a different router with everything else the same and see if it’s the peplink or not. Assuming you are using zero wifi?
