Now in beta for the international 7390's: ftp://service.avm.de/Beta/FRITZ!Box_7390_int./

I've been using this firmware for a few days now, and have been having daily line drops.
Bitswap isn't enabled anymore for downstream, and I wonder if this is the reason?
I'm either going to revert to the older firmware, or go back to using the openreach modem.

Can't you enable bitswap?

Immediate disike of the GUI you show. (I hadn't gone to it before my previous reply).

Since when has sync speed been synonymous with throughput? I'm surprised INP is off as well. (Assuming zero means off).

Not that I'm aware of. It was until I upgraded the firmware.

Doesn't the throughput equal the sync speed, between the modem and DSLAM, perhaps at a low enough layer?

Anyway IMP was 2.0 on ADSL, and has been 0 on VDSL2. It can be tweaked in the GUI.

Throughput is generally taken to mean data - in effect the maximum possible with a good speedtester. On any broadband there are substantial overheads (protocol control bits) to be subtracted from the sync speed.

How can it? The actual data (throughput) must be embedded within at least TCP/IP protocol info directing to which IP addy & port the data is being aimed at, yet more bits for the sync to carry.
