I have read this two times now ....

Me 3 times.
And I have a 4100 in front of my.
I've 4 igc0-1-2-3 interfaces, an ix2 and an ix3. The latter two are combo ports :
See here.

I presume the fix was : use WAN on igc0 and all the LANs on igc1, 2 and 3 - not using ix2 and ix3.

Yeah, I read that as using igc as WAN fixed it. In which case it's probably linking differently than ix to whatever is upstream. Potentially with or without flow-control.
You'd have to check the ifconfig output from each to know more.

@stephenw10 igc as WAN fixed it. What would cause this behaviour..?

ahxcjay

@gertjan correct. Once I removed ix from the ports used my line is at full speed on all uploads again! Amazing.

Thank you everyone!

I would think it must be something in the link negotiation there. I would check the ifconfig -vv output for each NIC to start with. It 'feels' like a flow control issue. You would see 'rxpause, txpause' in that output. It can be disabled (or enabled) on ix if it is that.

@stephenw10 great info. Thank you! I am so happy this is fixed as I love the product.

For the one and only 'ix' I use as a WAN to my 1Gbits/sec ISP router, I see :

ix3: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        description: WAN
        options=e138bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC,VLAN_HWFILTER,RXCSUM_IPV6,TXCSUM_IPV6>
        ether 90:ec:77:xx:39:2a
        inet6 fe80::92ec:77ff:fe29:392a%ix3 prefixlen 64 scopeid 0x8
        inet 192.168.10.5 netmask 0xffffff00 broadcast 192.168.10.255
        media: Ethernet autoselect (1000baseT <full-duplex,rxpause,txpause>)
        status: active
        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>

In short :

media: Ethernet autoselect (1000baseT <full-duplex,rxpause,txpause>)

for the port that is in use.

This is normal / not normal ?
Btw : I don't mind for now, as I have 23 Mbits/sec down and 2 Mbits/sec up for now.
Gbit fibre is coming at the end of the month.

We alle want to help, but it’s not very motivating when posts like yours just flame the product

Fair point, and I apologise. I was just so frustrated that I really really like the product, yet the upload speeds were killing my enjoyment of it. I asked the mods to change $subject to something more appropriate.

The problem is that google searches from people also finds this post, and some people only read headlines….

Understand, and that was in my thinking also, hence the request to change the $subject.

This post on the other hand, just earns the full respect of all of us

We can all make mistakes, especially when frustrated - but it takes a real man to own up to it, acknowledge a mistake was made and apologise.
If only all people showed this kind of respect instead of fleeing the “crime scene”, the Internet would be SO much a better place.

Thank you for responding and kudos to you
