I received my 166 from Broadband buyer today - it was replacing a 130 and I have stats from both. I think my line is pretty good anyway, so only saw a minor improvement.

@Craig

I've noticed that in Online Status --> Physical Connection it's got Google's DNS servers, 8.8.8.8 as Router Primary DNS and 8.8.4.4 as Router Secondary DNS...

Can you delete them or change them?

Thanks.

Are you asking if you can change DNS servers on a Draytek?  :D

Having never touched a 166 even I can answer that.

Yes.

It may be funny, but I've checked all the settings, and those Google addresses are nowhere...

Are they hard-coded perhaps?

There's nowhere to manually choose DNS servers?? or changing them has no effect?

That would be very odd indeed. Understatement.

Yes, there is (of course)

or changing them has no effect?
Exactly, DNS servers fields are blank/empty, so I thought it must take those Google addresses from somewhere in the firmware which is not actually displayed in the GUI ??

That would be very odd indeed. Understatement.
It is odd indeed... hopefully someone who actually owns the unit can shed some light on this...

I've recorded a quick click-through of the 166 web interface. I can't see anywhere to change the DNS settings shown on the Online Status > Physical Connection screen. I've even included a view of my router DHCP config - showing that these don't match.

I do have a theory though. Googles DNS servers might be the default, and when the device is operating in Bridge Mode the DNS servers are probably ignored as they're configured on the device initiating the PPPoE connection.

Hi

I just purchased one of these.
I’ll link below to the full operating manual, dns is mentioned on page 53 if it helps. In modem mode the DNS will be reliant on your routers dns selection.

Hi, can you test the baby jumbo frame support please. You will need to set MTU to 1500 (1508).

Linux command:
ping -c4 -M do -s 1472 1.1.1.1


Windows command:
ping -f -l 1472 1.1.1.1

Thanks,  ;D

Perfect! Thanks very much  ;D

Was it ever confirmed what chipset brand/model is being used?

Got one yesterday and have twice now had periods of 10% packet loss that were only resolved by restarting the modem.



1st one was at around 5pm the 2nd at 4am. Both times my connection was almost idle when it started & the error count for the line showed 0 both up & down.

Running 4.1.1_BT firmware on VDSL2 rather than G.fast

After 24 hours up I ended up with my ping doubled from 7ms to 14ms and losing 7Mbps from a already lacklustre 51Mbps (due to crosstalk I used to get 63Mbps) Also upstream is all over the place on the 166 with a constant bufferbloat for me of F on Thinkbroadband and spikes up to 312ms on upload too. Ive put my old ECI modem back on today and will be sending the 166 back, I'll await improvements if they come in the future but streaming UHD I need all the throughput I can get with background tasks running and Video chat is bad with upstream on this router on VDSL2 if something starts downloading in the background, of you get a few emails with images in etc, its really needs some work.

I am using my 166 in VDSL mode and haven't experienced the issues @Killhippie and @omegapoint are reporting. I've attached screenshots from the thinkbroadband tester - is there any chance you might have got a defective unit?
