I've VDSL at home and just have the modem plugged in sans filter, for where I live I think I get great speeds but was wondering if there is anything else I could squeeze out of it :-)
Edit : Bah, copy n paste got wrecked, will try pictures :

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?

BarTender: With a VDSL installation you shouldn't be using an inline filter. A professionally installed master filter which means you you can only use the VDSL modem in the dedicated outlet.
You should open a case with your ISP and say you need a master filter properly installed.

Hmmm ... I thought the splitter/filter just prevented the xDSL from interfering with your phone line (which is why I was curious about the comments of having one improving speeds) ? I don't have a phone line (gone VOIP) so have the modem plugged straight into the socket, no splitter/filter at all.
Not the right approach ? Couldn't find much in Snaps website about the subject.

So you are with snap and they didn't put a master filter in when you got connected?
How long have you had vdsl with them?

The main purpose of the filter is to isolate internal wiring. Since most homes are wired in parallel each jackpoint past that causes reflections. You can't put a figure on it - it could be anything from no difference up to a 30Mbps + gain and will depend entirely on your wiring.
If you want a good run down read my pretty extensive blog post on the issue.
Mark: I'll go hunt the blog down.
Wiring here is Chorus -> house -> modem.
The other jack points in the house have an air gap between them and the main jack point ... I got it separated just in case I did get a filter put in, so the output of the filter would go to the phone jacks, or I could always plug the analog connection of the Fritz Box there so I can run some analog phones.

If each jackpoint is connected in a star configuration from the wiring coming into the house then you should disconnect all jackpoints apart from the one that you plug your modem into. This should be done back at where the wire comes into your house. If it's wired in a series then often running a new cable from where the cable comes into your house to the dedicated jackpoint will improve things.
The primary reason to have a master filter / splitter is to split the POTS Voice service from the DSL Service. If you don't have POTS then you just need to make sure you have a single direct cable from the street to the jackpoint you are using your modem in.. And you are done.
