This is a narrative rather than a review but if you are considering buying either router mentioned you may want to take a note of my experiences.
The Openreach modem that was supplied with my Plusnet FTTC broadband was fixed to the wall. Over the years this had caused a huge dust stain reaching right to the ceiling. Being in a corner it was only really apparent when we came to redecorate. I decided it was time to replace the two box solution with a combined modem router. Unlike ADSL routers VDSL routers are quite thin on the ground. I decided on an Asus AC-DSL68U as my Asus RT-AC55U had been reliable.
During the summer months I spend long periods away from home with just short returns on a monthly basis. During one return I decided to make this change the local Currys were out of stock of the Asus router but a quick search found me a Netgear D7000 on offer at Maplins so I got one of those instead.
It isn’t obvious from the picture but these are unusually large for routers being almost a foot wide. That with the 3 external antennas would certainly put me off having one on view as would the ridiculously bright LEDs. You can turn off most of the LEDs but the power LED remains on. None of this matters to me as the mess of router, SamKnows box, and Vonage VOIP box all live behind my sofa.
I connected it all up, found I had to use a backdated firmware for fixed local IPs to work, configured it and all seemed well. I had only been away from home a few days when it was obvious that my internet connection at home was down as no updates were made to my weathersat pictures page, my security cameras were inaccessible, and my VOIP phone wasn’t contactable. The phone was annoying as it forwards any landline calls to my mobile but my biggest fear was a power circuit trip which had happened once before and cost me a freezer full of food. My son M0XDK popped in and reported that a network switch seemed to have powered itself down and he had to power cycle everything to get it all working again. A few days later the failure repeated. I replaced the switch but the dropouts still repeated and I realised it must be the Netgear D7000. There were some posts in forums describing a very similar problem. The Netgear had to go.
As luck would happen Maplin had an offer on the Asus AC-DSL68u I had originally wanted and I bought one away from home. On my last return I found that the Netgear was still running and the local network was fine but the VDSL connection had lost sync and not automatically reconnected. The connection is specified as always on. Reconnecting it got everything going again but doing that from 100 miles away with no internet connection is a little difficult.
This is smaller and more vertical than the Netgear but as is obvious in the picture still has the three large antennas – these do help with WiFi range but are probably not appealing to wives. Certainly I would have problems getting away with one if it wasn’t behind the sofa.
Anyhow I went though the necessary config with the only issue being I couldn’t get it to support my D-Link provided dynamic DNS service. This is not a problem right now as Plusnet offer a fixed IP but could be later if I change ISP. I have continued to update the dynamic DNS to make sure it doesn’t lapse even though I don’t need it and will dig into getting the Asus to support it later.
So with it up and running I was reasonably happy although I did spot a connection drop. Overnight there were a couple more and the BT dynamic line management kicked in – the result being I now have an interleaved connection increasing latency from ~ 10ms to ~ 20ms and dropping sync from ~ 71Mbps to ~ 68Mbps. It has remained stable since and for me is no big deal although I suspect a gamer would be mortified with the increased latency. A bonus is that the upstream has increased from ~ 17Mbps to ~ 18Mbps.
A new firmware was released while I was at the van but I deferred installing it until reurning home today 16 Oct 2016 in case I lost the connection completely while away. Initial results indicate that Firmware Version:126.96.36.199.380_4026 has restored the downstream speed back to what it was on the Openreach modem and retained the better upstream. On the downside it is still interleaved for downstream. The reported interleave depth is less than it was although the depth reported is whacky enough for me to doubt its accuracy and the ping actually increased marginally.
At long last interleave was turned off today (9 February 2017). On checking the line stats to confirm what the big decrease in latency shown on the TBB monitor was indeed a return to fastpath I see there is another firmware update available.
I held off installing that for a while in case the DLM interpreted the drop in connection to be a problem using fastpath and my profile didn’t increase until after I installed the firmware update and rebooted the router. Now I’m at last on an 80/20 sync and a 77.4Mbps profile which is probably the best this line has ever been. It’s a great pity that Plusnet are apparently now being very sniffy about retaining past discounts. Looking at current broadband prices would see me returning to cable if my minimum term was up right now and Plusnet wouldn’t play ball on discounts.
