bener:

 

Hio77 I think I get it, you've checked on your end...

 

It does seem a bit slower after I switched from VC MUX to LLC/SNAP

 

It's always been on the Draytek, the 2860 was installed at the same time as the VDSL connection. 

 

Thanks for you input. 

 

Do you think 1Mbps or less upload speed is acceptable for a VDSL connection with those line stats?

 

 

Previously a HG630 was on the line, Quite likely just to test an issue. i didn't dig into the case relating to when those tests were ran.

 

the line is syncing at 29/1.5 so on a speedtest you will probably see about 1.1 Upload given overhead.

 

If you are testing lower than that, Likely you need to look at other network usage on the connection.

 

 

 

Given the distance of the line, Yeah it's acceptable unfortunately, As noted i do feel the line could do more. but that seemed to be a combination of the modem and cabling used.

 

On a modem with a Broadcom chipset, you will probably do about 2mbit, and with SRA turned on that may crawl up a bit higher.

 

 

 


I personally have a line at home that's sitting on quite a long line, It sits at 21/0.9. Given it's distance It's acceptable.

@Hi077 and @Mattmannz, thanks for the suggestion, the upgraded firmware has improved download speed, but upload speed is still slow.

 

Current speedtest 30.72Mbps down, 1.09Mbps up.

 

Still seems pretty slow on upload.

 

If there is any other info I can provide that would help with any other suggestions please let me know!

@Hio77 thanks for looking into that - they will just have to live with it if it is based on the line length - at least we've gained a good 5Mbps in download speed.

 

If there was an HG630 on the line it must have been quite some time ago. Interesting that the chipset in the Draytek is slower than the Broadcom chipset in the HG630. I actually thought the Draytek was one of the best choices for VDSL connections! 

 

I'm guessing it's probably not worth swapping to a broadcom based modem just to squeeze out an extra 1Mbps upload - especially considering the Draytek is running a VPN.

 

I appreciate everybody's input on this one, the geekzone crew always delivers!

Personally i actually run NF4V's in bridge mode on all my VDSL lines

 

 

 

the chipset is very open to be played with, it pairs well with Chorus's choice of Line Cards and honestly is rock solid for a bridged link.

 

I'm not sure i would trust them to handle my vpns or Nat table requirements.

 

 

 

Your now vectored looking much better. Upstream still looks to be legging a little, but that's normal for Drayteks

 

 

 

 

 

The reason Drayteks are the chosen modem in the industry is, they are rock solid. They often prefer stability over raw bandwidth, which is what your after.

 

I would give the dslam a few nights to settle in, will keep an eye on it overnight for you though.

Thanks again @Hio77, there has definitely been an improvement. It may be taking a while to settle in as there have been a couple of outages since the upgrade, but I've rebooted the router now and it seems to be happy again.

 

I'll likely be back onsite in the morning so I can check their connection again and report back.

 

Definitely agree re: the Drayteks, I've used DV120's and 2860's for ADSL and VDSL that have been super reliable! I'll keep the NF4V in mind if someone wants to squeeze as much speed as they can out of a connection.

The Gotcha with ADSL is PPPoA, that's where the DV120's really shined, since they are just about the only PPPoA to PPPoE translation that actually works well..

 

With VDSL, it's all PTM so long as a modem bridges, any router could dial PPPoE through it. Makes life oh so much easier!

Yeah the DV120s can be magic on rural broadband lines!

That was another gz recommendation a few years back!

Just a quick update for @Hio77 - the speed has definitely increased but there seems to be some connectivity issues. 

 

The VOIP phones have been dropping out occasionally, and web pages do not resolve all the time - often it just stalls. I'm wondering if switching back to VC MUX (from LLC/SNAP) would make a difference here, as that's the only change that was made other than upgrading firmware...

I'm not in the office today, so somewhat limited.

 

 

 

Checking the test that was running overnight, upload bandwidth was maxed the whole time, this would without a doubt be the cause of your connectivity issues.

 

As mentioned earlier, I'd look into what's running on the network itself.

 

 

 

there were no drops, errors were quite limited which was my concern at first.

 

 

 

As to the upstream issues, looks like there may be a bridge tap on the line that's affecting US1.

 

While not ideal, there is very little that can be done to remove these typically.


 

noise seems slightly high too, is there a second line that runs along side this one?

Same problem exists when switched to VC/MUX - any suggestions from anyone? The connection is fast when it's working, but I get the 'took to long to respond' issue repeatedly with websites (NZ and International sites)

Thanks for getting back to me when out of office! There is a cloud backup on the NAS that could be maxing out the upload, I'll switch that onto a schedule. It was not affecting connectivity before I made these changes, but I'll make that change anyway.

 

I'm not sure how the physical line was installed so it's hard to say, I'll see if I can get any more information about that. 

 

Switching to VC MUX has had no noticeable affect either way.

The NAS had started an upload of a large file set so that could easily be the issue.

NAS is not uploading but connectivity issues are still there - the internet will just drop out randomly for a couple of minutes then come back up working fine.

Nothing on the Draktek data flow monitor is using much bandwidth either.

 

Edit: the connection seems to have settled in a bit. No dropouts for the last few hours.

@hio77 - sorry to resurrect this issue again, but the site in question has been experiencing internet outages since the firmware upgrade. 

 

Previously the VDSL connection was slower (~20/1Mbps) but very stable - zero reported outages over a long period of time. The connection is now faster (~30/1.2Mbps) but they have been experiencing connection loss for 2-5 minutes throughout the day. They have just called me again to say that the phones and internet are out for over five minutes currently.

 

I am just wondering if there is any assistance you could offer? I'm not sure what would solve the issue - I didn't take note of the version number of the previous firmware - I did back up the settings but the firmware was quite old so I hadn't thought I might need to roll back. 

 

Edit: there was nothing unusual on the data flow monitor last time I checked - the cloud backups are not running during the day.
