I’ve noticed the following behavior on a Pepwave Surf Soho MK3 with firmware 8.1.2 and a few VLANs defined:
- Change a network port (or a few) to type “Access” from “Trunk - Any” and select a VLAN.
- At this point the download speed might seem to be the same.
- Reboot the router (sometimes this isn’t necessary, but one time it appeared to be fine until a reboot).
- Check the download speed.
At this point I see extremely slow download speeds from a computer connected to an access port - over 10x slower than with the port set to “Trunk - Any”. However, the upload speed is fine. I can only restore the download speed to this port by setting ALL of the ports back to “Trunk - Any”. I haven’t changed any of the speed settings for the network ports from the default of “Auto”.
