PPPOE WAN drops.Reboot needed to work again

[mrvanity]

Hello.
I am using the latest version of pfsense on a box that used to run pfsense again before two years.
The NIC's are INTEL Pro 100.
My WAN is connected to a vdsl router configured for bridge, and pfsense does the PPPOE connection.
Some days ago,before connecting the VDSL line i had a ADSL line again via bridge/pppoe.

The problem is the same in both cases.When i max out the connection, (via speedtest.net lets say) the wan interface drops. (red down arrow,with no IP)

I have read about apinger, and disabled the monitoring in WAN interface. (also created a cron job to restart it every 3 minutes)
Also i have read about the auto-negotiation setting to default, but in only appears in "normal interfaces"(when you configure the interface to be used as pppoe, there is not negotiation setting).

1. Is there a way to force the autonegotiation setting  via cli?
2. Do you think it might be something else ,that i have to look?

My regards
