Hi all

I bought a TP-Link Archer VR600 (can't link to the product as I'm new here) from PB Tech to replace the standard VDSL router provided by Spark.

Mainly to provide better WiFi, but I entertained a mild hope I'd get better D/L speeds overall.

Monitoring from Speednet and Usenet showed that the old router./modem would top out at 2.1 - 2.3 MB/s, which was great (as I'm rural).

After putting in the new router, I now see speeds of 1.7 MB/s max. Whilst this is first world problem, it vexes me.

I've gone to the extent of playing with MTU size to see if any improvement could be gained there, but 1492 seems the magic number.

So, basically looking for assistance to see what - if anything - can be changed.

There's a QoS option in the admin system which I'm guess picks up certain values from Spark; namely:

Max Upstream Rate: 1056kBps

Max Downstream Rate: 16853 kBps

The latter value seems to correspond to the max MB/s that I'm seeing now....but that the previous router managed to exceed.

Does firmware play a part? IE the Huawei is able to ignore the settings and max out based on absolute maximum speed as opposed to a derived value?

Any thoughts would be most welcome! Thanks!

use hg630 as modem, tp-link as router.

Yeah, with the router in bridge mode...I will try that but I begrudge having to use 2 devices (and give up precious plug space) :)

i suspect its due to the devices having different chipsets, which can give differing speeds.

it also could be the TP-link doesn't support vectoring or ginp?

@hio77 is the one to talk with about this.

Put quite simply, various modems can and do sync at different sync rates due to a number of different reasons. Depending on how many times you've been swapping out your modem and having your connection going up and down you'll also find ddDLM could have a negative impact reducing sync speed because it thinks your connection is unstable.

MTU is nothing at all to do with your speed - it needs to be set at 1500 (preferred) or 1492 but I'm pretty sure none of the TP-Link's support a 1500 byte PPPoE MTU.

Thanks for the responses; I've only swapped the router/modem once to actually replace the Huawei one...there's been no back and forth.

TBH, I'm no expert on any of this stuff; everything I talked about is from various Googlage.

So, it sounds like the options are;

use the original modem/router as a pure modem and see if that makes a difference

Suck it up, things work differently to other things

Thanks!

In your situation what i'd do is..

I'd put the HG659b in bridge mode

https://www.spark.co.nz/help/internet-data/equipment/huawei/hg659-gateway/setup-bridge-mode-huawei-hg659-hg659b/

Terminate PPPoE on your new device with the better wifi.

This will give you both worlds, Newer Wifi Kit that will preform a tad better and the rocksolid performance of the broadcom based chipset in the HG659b.

Don't read into the "Max Values" Read the "Current Rate" - That's what your synced at.

Steve has hit the nail on the head around device differences.

It's not 659b it's 630b

Vdsl is very sensitive. You sneeze and speeds change. My Vdsl speed got lower over time. You may find that putting it back on the huawei may not bring the speed back to the past. In that case blame your neighbours.

Many thanks for the reply - I'll give that a go over Xmas!

Much appreciated, all

Otherwise you can get another router to provide the VDSL service rather than the TPLink.

I've got an old Draytek 2760 VDSL router which doesn't include WiFi that I had at home which was rock solid.

Granted the HG659 I have got slightly better sync speed but the stability I had with the Draytek I never needed to reboot it apart from when I did upgrades.

Was planning to put it up on Trademe for $50 so happy to sell you that if you want it.
