WAN bandwidth slow

[y2kw]

Hi,

When I connected directly to the router I get 800-900 Mbps, when I connect it through the OPN I get just 100-200Mbps.

The cables are CAT5E\6 the NIC is 1GB.

What else I should check? OPN config or anything else

What hardware are you running OPNsense on?

Are the WAN and/or LAN interfaces logging errors?

[y2kw]

Hyper-V
NIC- Intel PRO/1000 PT Desktop Adapter

Where I can see if there is errors?

[WN1X]

Interfaces-->Overview and check each interface (WAN and LAN).

Have you tried replacing the ethernet cables on both interfaces.

[y2kw]

No errors on both NICs

sure, at first.

it something related to OPN\Hyper v\Driver
but I don't know where to check and what

[y2kw]

Also change to another NIC at Virtual Switch Manager- still the same

I would research this from the hyper-v side and not OPNsense.
