GS108Ev3 port issues
Prosafe GS108ev3 8 port having issues with two ports underperforming throughput. Six of the ports deliver 100+ Mbps while two ports only reach 20 Mbps. Looking at the prosafe utility shows none of the ports have limits set on them. Suggestions?

Kindly answer the questions below:
a. What LAN ports on the GS108Ev3 that only reaches 20Mbps? (For example: ports 5 and 8)
b. What is the behavior of the LED lights of the LAN ports on the GS108Ev3 that only reaches 20Mbps?
c. What type of ethernet cable are you using on the devices connected to the 2 LAN ports that only reach 20Mbps? Is it a CAT5e or CAT6 ethernet cable?
d. Have you tried changing the ethernet cable on the devices connected to the 2 LAN ports that only reach 20Mbps?
e. What are the devices connected to these 2 LAN ports that only reach 20Mbps? Kindly indicate the brand and model of the device.
f. Have you tried updating the software driver of the LAN card of the devices connected to these 2 LAN ports that only reach 20Mbps?

Hi SAH2016,
One more question, 6 ports deliver 100+ Mbps while 2 ports only reach 20 Mbps, how did you measure port forwarding performance? Kindly let's know if you use any addtional tools?

Wanted to re-rest after restoring switch to factory settings and restarting. I also tested multiple cables to ensure that was not causing inconsistencies. Additionally I performed all new tests with no other users on the network.
My complete layout is the following:
Netgear CM400 Cable Modem with Comcast service - tested speed suing Xfinity speed test; out of modem was 150Mbps for both IPv4 and v6
Apple Extreme - all ethernet ports showing performance of 150+ also.
Netgear Prosafe GS108Ev3 - In the same room as modem and Extreme.
PaKedge 55WPDE (5) switch - In the same room as modem and Extreme.
Used a Macbook and Dell laptop using Xfinity Speed test on all ports of Extreme, Netgear and PaKedge switches in the same room with no other cables attached other than to the Extreme and one laptop at a time. Additionally changed the ethernet cables to each switch to ensure that was not an issue.
All Netgear switch ports are now delivering 20-25 Mbps with both lights on when ethernet cable attached and IPv4 and IPv6
Pakedge switch delivers 150+ out of all ports. Checked end of remote connection to PaKedge switch and was also getting 150+ hard wired (Ethernet wire in walls to remote study, hard wired to Macbook and Dell, both saw 150+ Mbps).
I'm stumped.....any suggestions?
