Hi,

I updated my turris installation from 3.11.26 through Foris experimental update.

Apart from other glitches the main problem which made me go back to TOS 3.11 is that WAN Speed dropped from ~600Mbit to ~13Mbit on TOS 5.x

I have checked /etc/config/network but couldn't see anything suspicious. I also the only special setup here's the 3g and ncm interfaces apart from this I have a very simple config. Not vlan's nothing just plain DHCP on wan side.

Here's the 3.11 config:

config interface 'loopback'
        option ifname 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config globals 'globals'
        option ula_prefix 'fda6:7fef:b222::/48'

config interface 'lan'
        option ifname 'eth0 eth2'
        option force_link '1'
        option type 'bridge'
        option proto 'static'

I also check ifconfig, cpu load etc. everything seems completely normal.

Also when checking eth2 with ethtool, I get this output: Settings for eth2:

I have absolutely no idea why WAN is so slow after updating from 3.11.26 to 5.1.4.
