DrayTek Vigor 2820 and BT Infinity Connection Problems

Hi everyone,

We're having a few issues with BT Infinity when using a DrayTek Vigor 2820.

We stopped using the official BT Home Hub router when we started having endless port forwarding issues (which I don't really want to go in to here.. it's a long story!)

We did some reviews, and ended up purchasing a new DrayTek Vigor 2820 Fibre modem/router. It's connected to the BT Openreach VDSL fibre modem.

We seem to be getting random drops in connection, sometimes the cable modem drops which results in a log at BT's end showing the connection disconnect. Usually, the connection doesn't drop, it just appears to time out for around 2-5 seconds. If you're downloading, it cuts the download - so is quite annoying! Occasionally it does report a dropped connection at BT's end, but it's not often enough for them to s

I've looked into the logs on the DrayTek which don't show that much - lines of interest are below.

Any ideas anyone could suggest would be most appreciated!

Andy
