If the SH4 works similarly to the older hubs, only one Ethernet port is available in modem mode. It would be pretty awesome if they allowed lag groups in modem mode on the new hub to get around that issue but I’m not getting my hopes up. I still have to wait for gig1 to come to my area too though so no opportunities to play with it for a while.
Erm, ok just tried it in modem only mode and it worked with all 3 connections...
All 3 were seeing different traffic levels going across it and with 2 disabled it speedtests hit the expected 930 or so. Enabling the other two pushed it back up to the max 1.1Gbps or so. I put 3 connections in as in testing with just 2 it tended to stick to one connection.
I know the behaviour of the SH3 is only one port, however I wonder if this is really the case. Not sure how my new router is presenting itself as it has a single IP address across all 3 connections in all cases either a 192.168.1.x address or the public IP address in modem only mode.
More testing to follow as I want to check my new routers firewall is working as expected.
The Mikrotik router config establishes the bond between the 3 and gives out the same MAC address to each port in both router and modem only mode.
Random round-robin is configured on the bond and during a speedtest typically you can see the bandwidth split between 2 of the 3 connections usually with around 2/3 to 1/3 split. This varies but in normal use you can see different levels of traffic going through each of the bonded ports in the router menus.
One of the issues I see is the default Gigabit Ethernet has a potential frame throughput of 81000 per second and therefore a high throughput for actual data (about 118 MB/s), giving efficiency of 94%, or 940Mbps. So in your case with a round robin each port will only get approx 940mbs.
