OK, So the connection between the A6 and the Netgear switch is 1gbps (seen from the screenshots), between Netgear switch and your home server is 1gbps (you've confirmed), but you get under 100mbps...

Can you check your home server LAN settings to see what's the associated speed of the LAN card ?

Do you have a switch after the A6 device ? I can see that you have 3 wired clients connected on LAN1 @1gbps speed.

@ThatCamOp91 Can you post the following screenshot:

@Akash94 It could be due to a couple of reasons. Is your FW an EU version ? You should be able to see that on the sticker at the bottom. If it is, then upgrade with this FW to 1.3.6:...

If you use the original power adapter that should be fine. So you are with the 1.3.6 version now, right ? Have a hard reset - (Method 1) and see if there's any change. If the issue still persists...
