RT-AC86U 384.16 Hi, I updated to the latest Merlin firmware this morning (about 9 am) and since doing so my NE CRC count has gone up to 326598 over 5 hours. ...

[Mrk26]

Not bad now, let’s see how will looks like tomorrow.

These don’t looking promising, unfortunately..

I think is worth to check how modem will perform on test socket before you report fault to BT.

I will plug modem into test socket first thing tomorrow morning and see how it goes.

SNR has increased by 1 db

When I need to how do I reset SNR to default?

Try:

• Switch on router.
• For at least 10 seconds, press the Factory Reset button
• Device is automatically restarted.
• Default settings have been restored.

Never tried this myself but should bring DrayTeK 130 back to how it was when it first was plugged in.

The only issue with re-tweaking the modem, is that when BT check your line, it is best to have modem at default incase they decide to check what stats your modem is reporting, highly unlikely, but it has happened with me when I had my Fritz!Box as I had a line branching problem which Fritz!Box identified, BT underground  works team then dug up the  road and sorted my connection
