10 Most Frequently Asked Questions

Why does my ADSL or NBN VDSL constantly drop out?   [ 5 MOST COMMON REASONS ]

There are many causes of loss of sync on an NBN VDSL or standard ADSL service.
But with over two decades of working on DSL services under our belts, we have identified the five main causes of sync loss.

Unfiltered devices on the DSL line (Telephone or Alarm systems)

Remedy: Make sure all unfiltered devices are either removed from the DSL line or have an inline filter attached. In the case of back to base alarm systems, you may require the installation of a Central splitter for legacy ADSL. For NBN FTTN/FTTC, your monitoring company will be able to organise the installation of a cellular device to continue your monitoring.

Faulty joins in cables or faulty internal wiring

Wires twisted together in the roof, or corroded/poorly terminated wires at the socket are both a major cause of slow DSL and loss of connectivity.
Faulty cables can also be a cause, however in most cases, the terminations that join the cables are the culprit.
If you experience sync issues only at certain times, for example at dawn or dusk, the most common issue is temperature change, which will cause faulty joins to expand and contract due to temperature changes, resulting in loss of sync.

An eTechs technician can quickly identify these types of issues. We can normally locate and repair faulty joins or terminations within 30-60 minutes.

Faulty modem or patch leads and telephone adaptors.

Faulty modems are also a cause, however if your modem is faulty it is most likely to not connect at all, rather than have intermittent disconnections. If you have lost connectivity completely then one of the first steps to take is to try an alternate modem. If you can borrow a modem from a friend or neighbour for testing then it will save you the expense of buying one unnecessarily. Your service provider may also be able to send you a loan test modem.

Long patch leads should be avoided. We recommend a maximum length of 2m between your telephone outlet and the modem. Replacing the telephone cable should also be one of the first steps to take in troubleshooting disconnection issues

If you have an old style 600 series telephone outlet then you will need a telephone adaptor to connect your newer style RJ patch lead. These adaptors are cheaply made and are notorious for being faulty. Upgrading you socket to a newer style RJ socket would be the best solution.

Fault on the carrier line external to your property

Faults on the external Telstra/NBN line are also a common occurrence, however we find more faults with ADSL services due to the longer line length. Our testing shows that NBN FTTC and FTTN services have fewer external faults compared to ADSL, however we estimate that around 10% of speed and loss of sync issues that we have tested on NBN services are due to external factors and 90% being with internal customer cabling.

Your first port of call if you suspect an external fault should be your service provider. They will perform remote testing and may send one of their technicians to investigate further. Your service provider's technician, however, may not have the resources or expertise to effectively diagnose and resolve your issue which may leave you in limbo with slow or disconnecting Internet.

At this point you may wish to engage an eTechs technician to test the external carrier line for faults. eTechs have the necessary tools and experience to locate issues that could be affecting your service. eTechs have been working with Internet Service Providers since the introduction of ADSL in Australia and have developed the skills needed to help resolve ADSL and VDSL related issues.

Excessive cabling and sockets in your building.

NBN FTTC and FTTN are dramatically affected by excess cabling and sockets in your home.
Your service provider may also refer to this issue with your cabling as a “Bridge Tap”
In simple terms, If you have any more than one socket connected to your NBN VDSL line then the chances are you will not experience the throughput speed that your line is capable of, and may also experience intermittent loss of connectivity. It is recommended that all sockets be disconnected from the NBN line, leaving only one socket. This will ensure that your internal cabling is optimal. It is also recommended that the older style 600 series sockets be replaced with the newer RJ type. NBN will generally not attend a fault when a Bridge Tap is found inside the customer home (remote testing). They will ask that you have these removed to see if this is the cause of the issue.

Why is my NBN VDSL or ADSL so slow?

90% of sync speed issues are found to be inside customer premises

For NBN FTTN and FTTC services, we find that 90% of speed issues are related to customer Internal cabling. NBN services (VDSL) are dramatically affected by reflections from internal cables branching off (bridge Taps) to various sockets.

Even if your new home has the latest CAT6A-CAT8 cabling, your speed will be reduced if you have more than one socket connected, generally by a third, but we've seen as much as half the attainable speed by the time it gets to the socket.

Bridge Taps - Series Wiring

If your house cabling is wired in series (daisy chained from one socket to the next and so on) then the end socket will always be the best socket to use, and the only socket which will give you the full attainable speed. If you use the middle socket in a chain then you will most likely have speed issues and may wish to have your unused sockets removed.

Bridge Taps - Star Wiring

Star wiring is where cables are joined in one or more locations and each branch feeds a separate socket. These joins can be at the building's cable entry enclosure, or in the roof, most often both.

In this scenario you will always gain less sync speed at every socket due to signal reflections from unterminated cables at the unused sockets.

ADSL can also be affected by bridge taps, however not nearly as dramatically as VDSL.

It's not always bridge taps

Other issues affecting your service may be due to a faulty carrier line, faulty sockets, or poor joins in your internal cabling.

How can I speed up my NBN VDSL?

'Attainable' Sync Speed

You can check with your provider to see what sync speed they estimate is 'attainable' at your premises based on line length from the node.

If you're already achieving the maximum sync speed that's coming into your home or business, then there's really not a lot you can do.

If, however, you aren't getting the right speeds at your socket, then it's highly probable that your internal cabling is either faulty, or isn't optimised for VDSL.

Unless an NBN network fault is causing low sync speed, there's every chance of achieving the attainable speed at your socket. This is done by reconfiguring your existing cabling and re-terminating old or faulty joins.
In some cases it may be more economical to run a new cable from the building entry point to the socket.

Who can I call to help me fix my Internet problems?

Not all Cablers are the same

When it comes to ADSL or VDSL issues you should engage a licensed cabler who specialises in DSL technology.

Not all licenced cablers are able to recognise and diagnose issues affecting a DSL service.
The technician you engage should carry specialised test equipment to test the copper lines for potential faults, as well as the VDSL signal for DSLAM faults coming from the node.

Can you just use your electrician?

Many electricians are licensed to work on telephone lines so they can offer a full installation service for comms and electrical. But they're primarily electricians, not many carry the right instruments to test VDSL or copper telephony circuits.
They're generally not equipped to fault find VDSL issues. To really know what's going on with a fault you need to be able to analyse data streams, bandwidth, bit errors, channel loading, spectrum noise (background noise) etc, otherwise it's all guesswork.

What is the best setup for my home cabling to optimise NBN VDSL FTTC or FTTN speed?

Single line from entry point to socket

In terms of having the best speed possible from the NBN node to your modem, the optimal setup is to have one cable running from your building entry point to one socket in your house. This is due to the Bridge Tap effect.

90% of sync speed issues are found to be inside customer premises

For NBN FTTN and FTTC services, we find that 90% of speed issues are related to customer Internal cabling. NBN services (VDSL) are dramatically affected by reflections from internal cables branching off (bridge Taps) to various sockets.

Should I have a new internal cable installed for NBN FTTN or FTTC?

If your internal cabling is not damaged in any way, then in most cases you do not need to run a new cable.

Existing cables can normally be rewired to disconnect all unused sockets and cabling and connect the NBN service straight through to one socket. Any joins are re-terminated to ensure no hidden resistance faults exist.

This process will normally take between 30-60 min.

Some older types of cable should be replaced however. Some of the earliest cabling used by Telstra has very poor protection from the electrical noise found in your home wiring, which can cause packet loss and dropouts.

eTechs technicians can inspect and test your existing cabling to determine whether it can be reconfigured for optimum service. If not, a new line can be installed from building entry point to socket.

Why do my telephone sockets no longer work for telephone with NBN?

The way dial tone was generated before NBN

Prior to the NBN rollout, dial tone was generated at the local Telstra exchange, sent to your premises along copper cables in the street, and then appeared at each of your telephone sockets.

The way NBN dial tone works

This has drastically changed with NBN. NBN 'Landlines' are now generated by your modem as 'VoIP' services (Voice over Internet Protocol). So instead of plugging telephones into wall sockets, you now plug your handset into the back of your NBN modem's VoIP port to get dial tone. You can then make and receive calls as you did before.

To distribute multiple handsets throughout your premises, the easy solution is to use a 'base station' node cordless phone to plug into your modem. These usually come with satellite handsets which only require power to run, and talk to base station through a radio frequency. The satellite handsets can make and receive calls just as the base station unit. Dot the 'satellite' handsets around your home wherever you need a telephone.
This is likely to be the cheapest and most convenient solution to distributing handsets throughout your home.

What if I want my existing sockets to still work?

Some people would rather still use their existing wall phones and handsets, and this can be achieved with a minimal re-configuration of your existing telephone cabling.

eTechs technicians can rewire your existing cabling to feed the VoIP port of the modem back through to your existing sockets.
If no additional cabling is required, which is the case 90% of the time, this type of work normally takes around one hour, so can be comparable in price to purchasing new cordless handsets.

Should I install home network cables or use WiFi?

Why install Data Cabling?

The short answer – for reliability and speed.

But really, there's so much to ge gained from having data cabling available in your network, it makes a lot of sense to install at least some.

Free up Wi-Fi Bandwidth for other devices

Connecting as many of the devices in your network as possible by cable, frees up Wi-Fi bandwidth for the devices that solely rely on it, like phones, tablets, etc. This ensures everyone enjoys the most bandwidth available.

For gaming, video streaming, file transfer, generally all bandwidth hungry applications, cabled connections are really the best way to go

A good rule of thumb is to apply the adage ‘if it has a network port, use it’. Follow that as a guideline and you can't go too far wrong.
Data cabling can dependably deliver speeds up to 20x faster than Wi-Fi. Also, unlike Wi-Fi, it isn’t affected by interference from other networks, distance from the router, walls, or the number of users competing for signal bandwidth.

What else can you use data cabling for?

Structured cabling (data cable) has the ability to carry other services as well, not just LAN and Internet traffic. For instance, HDMI can be converted to stream over a CAT6, or CAT6A cable to distribute video throughout your home. Also VoIP, TV signals, audio, CCTV, and PoE (Power over Ethernet) are some other services.
