IT didnt work :-)

But now the netgear is also showing problem dropping packets and this
is what we got from the support team of the ISP.

=========

Attached is the screen shot when the laptop was directly connected to
the modem and tested. We are getting 2 Mbps upload and download
consistently without producing any packet drop to the ping request
given to DNS.

ISSUE : Mismatch in negotiation settings with modem and CPE.

CPE : Netgear WIFI Router with no option to manage negotiation settings.

ASMI52 Modem is set to Auto OFF 100F.

This mismatch will lead link to migrate to half duplex mode and making
issues in upload stream.

Advised Mr. Joby to migrate CPE that supports to manage negotiation settings.

=========================

So it is auto negotiation problem as Reyk suggested at first but how
to get rid of it in OpenBSD NIC?

thanks
