I've recently moved from fiber zone to ADSL zone, so trying to optimise the home network as much as possible.

I have a USG, US-860W and UAP-AC-PRO, so figured the Draytek 130 was the best option for a PPPOE -> PPPOA bridge modem.

The ADSL sync speed has dropped fairly significantly in terms of % from 14mbps down to 12mbps (even the Chorus website now shows Current Speed: 14mbps).

Is this expected?

Is the Huawei HG659b sync better as it's Broadcomm?

Are there any other tweaks I can make on the Draytek to get the sync higher?
