This could be caused by a faulty ADSL module within the Vigor router - however if it is a new connection it is most likely that the new connection was not setup correctly. Please check the Router Configurator's "Online Status" page, and look at the ADSL...
Please see the ADSL troubleshooting notes here. Note that curerently (April 2006) Telstra does not provide ADSL2 through its DSLAMs so your phone line will have to be disconnected from the Telstra DSLAm and connected to your ISP's DSLAM ... and thus...
Your Vigor 2700 or 2800 uses an ADSL2/2+ modem chipset capable of communication at up to 24Mbps over a standard copper phone line. At the telephone exchange your phone line is connected to a DSLAM; which is effectively a group of ADSL modems in one ...
DrayTek routers are pre-configured to the maximum packet size of 1492 bytes (being 1500 bytes less IP headers). However some ISPs use other maximum packet sizes - most noticable TSN with 1400 or Chilli with 1500.  To change the MTU to 1400 : With ol...
Check the Vigor router's Online Status page. Starting from the bottom of the page, look at the ADSL STATUS section. If the data is in red, such as below, then the modem cannot detect an ADSL signal on the phone line. There are several possibilities, ...
Yes ... though there are a few considerations: Vigor 2700 and Vigor 2800 models use ADSL2 modem chipsets, and so will be able to work at up to 24Mbps (ADSL2+) when connected to an ADSL2 DSLAM and on an ADSL2/2+ ISP plan.   Note that ADSL2/2+ issue...
If the ADSL Status is green (with State = SHOWTIME) the ADSL modem can 'hear' the ADSL signal. If the WAN Status section data is red, then the problem is with the PPPoE/PPPoA connection. In our experience the most common problem here is that the userna...
For the Draytek ADSL1 modem/router units, which includes Vigor 2500/V/We, 2600/V/G/VG/Ge/plus: All the Draytek models specified above support the G.DMT modulation (ADSL1 standard), so provided that the ADSL2/2+ ISP also support G.DMT modulation, then ...

Because ADSL2 (max 12Mbps) and ADSL2+ (24Mbps) operate at much higher speeds, they are more prone to interference and noise on the phone line than ADSL1. Unfortunately debugging ADSL2/2+ synchronisation and drop-out problems is very much an arcane a...
Unfortunately ADSL2/2+ is still more of an art than a sciience, with most suggestions being "try this..." or "try that ...". So how can you know whether there is and improvement ? Fortunately most of the information can be inferred from the Online Stat...
