2860ac with Vodafone superfast, using Vodafone supplied username and password. Have tried v3.91 BT, and v3.91 vector 2 firmwares. Have left it connected for a few weeks.

Thanks.

What do your line stats look like?

Disconnections happen seemingly at random, roughly 2 times a day. Vodafone supplied router rarely drops connection.

Your stats show interleave depth 1, which suggests either some problems on the line or a result of the router dropping the connection too frequently. It's not clear how long this current connection, as exemplified by your stats, has been up, but in terms of error count, it all looks good.

Our Draytek frequently dropped the connection when our SNR was 3db. Increasing the SNR on your Draytek might help stabilise the situation, but at the cost of speed. I suggest raising the SNR to 6db at least as a temp measure. (Remember to save the setting, per Hornbyp's instructions.)

I'll repeat here what I said before: I don't think older Draytek routers (like 2860 or 2762 etc) are handling Huawei cabinets well, which you're clearly connected to. That's why your Vodafone, which has a newer Broadcom chipset, as opposed to an older Lantiq chipset on the above Draytek routers, is much better at being in sync.

The newer Lantiq chipsets (like the one in my Fritzbox 7530) are comparable to Broadcom ones.
