It can’t be in the description because it wasn’t designed that way.
The bonding proxy on the IB2 bundles two Internet channels using Distributed TCP, i.e. the IB2 distributes the TCP packets from a single client to both channels and incoming packets for a client can also arrive at the IB2 in parallel over both lines and are then reassembled by the proxy for the individual client.
The only known limitation for bonding is (at least it was when I had a booster myself) that it really only works with TCP traffic and not with UDP traffic (e.g. access from outside to a UDP-configured Open VPN server).
Had 50 MBit/sec copper + 50 MBit/sec LTE download for two years and never excluded any device from bonding (except the TV boxes, which are blocked by Swisscom by definition) and never had a problem with 100 MBit/sec download on a client as a direct individual download.
If this doesn’t work for you (e.g. for a normal speed test like CNLab), it’s not due to the bonding in general, but must be due to a local limitation.
By the way, you can easily see how many MBit/sec the booster actually delivers in the LAN diagnosis of the IB2’s expert menu during a long-running speed test, provided you have connected the booster to the IB2 via a LAN-Anschluss.
If you are really interested in reliable speed tests:
- Don’t use a browser but rather the CNLab test program installed locally under Windows (free download from the Internet)
- Always test with the PC connected directly to the IB2 via cable
