We have recently had fibre laid in our area. Countless Broadband suppliers have made maildrops asking to be considered as our preferred internet supplier, with most if not all offering deals. Most (maybe all) offer a free modem.


We have Voip phones and when we installed them we needed a new modem and have a TP Link 300Mbps Wireless N ADSL 2+ modem router


Model TD-VG3631


Because we have a near new router which works well on copper lines, do we need a new router for fibre?

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:

Your current modem will work as one of the Ethernet Ports can be used as a WAN port (EWAN).


After a quick search it seems that that router also supports VLAN tagging, so should work with all flavours of UFB.


If you go with Bigpipe, they don't require VLAN tagging, so it should work fine with them.

100 megabit, and on ones when you use the lan port as a wan port there can be other congestion issues in the internal switch that make it not able to even get the full 100 meg each way.


If you go on the cheapest slowest fiber plan it will be fine, but a half decent one or better, it is a potential bottleneck.

And isn't the router offered by Vodafone, Spark, and BigPipe wireless AC as opposed to N? That would make it better than what you have anyway.
