Just got my sweet new Fritzbox for my VDSL connection and I noticed my sync speed has dropped back from 18mbps to 16. Does anyone know if Snap cap this out at 18? Line stats below, but im not exactly phased.....more interested.

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

If you are posting regarding DSL speeds please check that

- you have reset your modem and router

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

- you are not being throttled by your ISP due to going over the monthly cap

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

- you read this topic and follow the instructions there.

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

- Your ISP and plan

- Type of connection (ADSL, ADSL2, VDSL)

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

- Your general location (or street)

- If you are rural or urban

- If you know your connection is to an exchange, cabinet or conklin

- If your connection is to a ULL or wholesale service

- If you have done an isolation test as per the link above

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

I recommend you read these two blog posts:

- Is your premises phone wiring impacting your broadband performance? (very technical)

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?

Just to note - this is still ADSL.

ISP's can't control the sync rate - this is negotiated between the modem and the ISAM linecard and can vary between different modems.

I have the exact same situation. I was using a Billion 7800n and syncing around 17.5-18mbps. Got the Fritzbox and now syncing at 16.4mbps. Not the end of the world, as I'm waiting on the transfer to VDSL. Here is my screenshot

Same here. After hearing so much about the Fritz!Box, I decided to grab one when switching to Snap VDSL. Still on ADSL, but the syn rate has dropped compared to the Thompson device I was using, which is actually VDSL capable. I'll have to plug the Thompson back in when VDSL is up to see how much of a difference there is with the sync rate.

the fritzbox's performance with adsl is generally worse than broadcom, which is meant to be slower than some other chipsets according to whirlpool forums. in nz broadcom seems to work well though.

vdsl performance doesn't seem to be an issue with them though, so i wouldn't worry, and would just do the vdsl thing.

This is something that I find quite interesting actually. The fritz!box 7390 has the same issue, but also with VDSL for me anyway.

I've got two 7390's both of which sync'd at a maximum of aproximately 36mb/s maybe 37 if I was lucky.

Then I tried another modem (innbox V50-U), and my sync has jumped up and become stable at 41mb/s?

ahh ok, could be the case. at those kinds of speeds it matters less though,.

How so? Dropping from roughly 18 mbps to 16, is an 11% hit to ADSL bandwidth. That is approximately the same margin as going from 41 to 36-37 on VDSL. For certain common use cases, such as browsing static web pages and watching low-res YouTube clips, one may not miss the overhead on VDSL, but for other uses, such as the ones VDSL opens up (higher resolution video, all of the uses of the upstream connection, etc.) you're still getting dinged.

you're not getting dinged nearly as much as you're dinged by chorus's conservative noise margin.

high resolution video works fine at 16 megabit. if you really care very strongly you can always use a diff modem.
