Thank-you.

20 Mbps is quite an overhead!

I sync at 330 Mbps and get about 293 Mbps throughput in the best case. So, ignoring IP profiles, I get about 0.89% of the sync rate.

If you're getting about 141 Mbps, then using 0.89% would sorta match up.

It's certainly a large overhead, I would agree.

My G.fast are much similiar to Robbie 160/30 as Openreach test kit say max data rate are 210/29 compare to him 223/31 and my real throughput speed is 151/27.8 with TalkTalk Business (this test run direct to ethernet 2.5Gbps) from TP Link WAN port 1Gbp connected to Openreach Gfast Modem 1Gbp lan port via samknows speed test.

My gfast line attenuation are 38.0dB SNR at 4.0dB (downstream) no interleaved

- Wait for the Vigor 166 v2 - Vapourware?

Old thread, but the Vigor 166 definitely exists and I think it's the only one that's ever shipped in the UK; the v2 supports 212Mhz which Openreach say they will never support in the UK as it interferes with other services (crosstalk etc.)

There's a dedicated thread on these forums to reviewing the vigor 166.
So far everyone with the vigor 166 has a v1 and not a v2.

Seeing as OpenReach don't use frequencies above 106MHz it makes little difference to own a v1 or v2 in the UK.

I've been playing with a GEN2 model from Germany & can report that here in the UK it's performance is just the same as the GEN1.
In fact they even share the same firmware (as of v4.1.1 - currently running V4.2.3)
Incidentally, for anyone with an EU GEN1 or GEN2 model, DrayTek in Germany now has a dedicated BETA firmware page here:
