Mick, There are stack of things that can affect the performance of your FTTN service:
Check this map to find out the estimated distance you are from your node along with a gestimate of the speed that should be achievable(Search for your address then click the dot).
NBN MTM Alpha
In your home:
Remedying old wiring can give possibly the biggest improvement, people have seen significant improvement in speed and reliability by doing the following:
- Before starting this process get a baseline of your modems sync speeds. This is the speed at which data can be transferred up/down with the current line quality. This information is available from the modems management console which you should be able to log into and retrieve. This speed should hopefully be close to what you got from the map above. If it is then your line quality is good - your attention will be more focused on reducing the dropouts.
- Disconnect wiring to all outlets other than the one your modem is connected to so you just have the single line running to your modems wall plug(no branches/joins)
- ideally have a new cat5/6 cable run from the lead-in (cable that comes from the street) to your modems location.
- Make sure the cable is kept away from power wiring
- Make sure the cable is not routed near fridges/washing machines/driers etc. The starting and stopping of motors will induce interference in cables run near them causing dropouts.
- make sure the modem has clean power - a surge protector can help with this
- Check your modems sync speeds again to see if you have achieved improvement - ideally your sync speed will be similar to that estimated on the map above
Once your internal wiring is in order, you can check if any further limitation is related to your connection (poor copper quality or distance) back to the node or is a limitation of your ISP:
- If your sync speed is significantly lower than what the map above estimates you should get then it is likely you have an issue with the line between your house and the node. Complain to your RSP so they can have NBN sort it out (good luck).
- If your sync speed exceeds your plan then then you should expect to get your full plan speed. Your RSP will limit your speed to the plan. (Use an online speed test tool to check your actual speeds)
- if you are getting much less than your plan and less than your sync speed then this points to an issue with your RSP. This will be most evident with slow downs in the evening when more people are online and things get busy. This happens because your RSP has oversold the bandwidth they have purchased from NBN for your locality (this is called CVC). I.E. they have bought capacity for 100 subscribers but sold it to 1000 - while not many are using it performance is fine, but when everyone is using it it is terrible. This is when you need to be looking for a new RSP and as much as people put them down, Telstra is one of the best performers (it's their customer service that lets them down), Aussie Broadband has an excellent reputation on all fronts.
- If your sync speed is lower than your plan speed eg plan speed is 100/40 but sync speed is 70/30 then this may well be due to the physical limitations of the line such as your distance from the node - nothing can be done about this.
Unfortunately with FTTN, users need to do everything they can to make sure their home wiring is in order. Getting a licensed cabler to do this is most effective. Once this is done it removes a factor that the RSP/NBN can blame on you.
In your particular case it looks like you need to sort wiring to stop the dropouts and change RSPs to get rid of the slowdowns. If the dropouts continue, there are steps that can be taken to see if the problem is internal or external but, that will be next.
Hope this helps a bit.
