Re: which fttc router.

As I said, it uses PTM, however, the basic difference is that VDSL2 still uses DMT, whereas Ethernet uses PAM. Remember this is not EFM, which is where you're getting confused.

Encapsulation of PTM packets still does not make the device a router. Nor does the modulation standard used bear any relevance - Ethernet does not only use PAM either, nor does it care.Optical and copper ethernet uses different modulation but none of that is at all relevant

Regardless of whether we agree on terminology on the definition of a router, EFM or PTM, the "device" performs drastically different functions depending on whether the WAN connection setting is set to "Route" or "Bridge". Like most other consumer routers, even those with ethernet ports on both sides of the connection, the routing functions drastically slow down throughput. That was the whole point of this discussion.

In bridge mode, it performs no IP layer operations whatsoever. That's the difference.

Unless you actually have your device set to "Route" instead of "Bridge", and have gotten much higher speeds, my point stands. The device is limited to around 60mbps in router mode.

Your device may be limited but I'm yet to see any data. However, mine is fine.
I suspect you don't have FTTC at all.

I have given you the data - in the form of the speeds attained in the different modes, i.e. the whole point of this discussion. What other data is relevant? Is data incorrect because I typed it instead of copying and pasting it from a canned speedtest page?

I also asked you exactly what settings you're using on your device, so I could compare if I had missed anything that would have caused the difference.

That's why I asked you for a link. You can type whatever you want, but it's hard to forge a link.

A link to what exactly?

Everything done by a person has to be typed up by someone at some stage.

A link to a speedtest result showing FTTC maxing out at 60 Mbps in router mode.

Here's a funny thing - when you're 100 miles away from Lancaster in router mode you get below 60, but when you're 150 miles away from Lancaster in bridge mode you get above 60.

I'd say it is related to your IP address rather than the mode.

Do we know if this is compatible with both types of fttc equipement. Have asked on their forums but no reply as yet.
