Broadband Router System

ADSL drop-outs can be caused by:

1. Internet Service Provider: Lack of ability to connect to

(a) Authentication servers, which periodically validate the subscriber's username and

password

(b) Default gateway (through which access to all Internet services must pass) or

www.google.com, and related IP addresses, e.g., 74.125.31.104)

2. The relevant telco/s providing the exchange hardware and copper phone lines

(a) Problems with the exchange ADSL hardware

(b) Poor quality or excessively long phone lines.

3. Subscriber infrastructure

(a) Damaged in-house phone lines

(b) Conflicting in-house phone-attached hardware

The analysis of these causes is as follows:

1. F-Tel have claimed, during episodes of drop-out, that “everything is OK” at their end.

This cannot be regarded as definitive, but it is likely that the problem rests elsewhere.

2. Telco problems tend not to be intermittent:

(a) problems with ADSL hardware tend to cause permanent ADSL disconnections

until resolved, and

(b) phone line quality and length problems would be evident at all times, resulting in

poor speeds or constant (as proposed to intermittent) drop-outs.

(a) Usually damaged phone lines show up through phone as well as ADSL problems;

however, the phone system is VoIP, and does not rely on the PSTN lines into the

house except via the ADSL. Therefore this is a candidate; only an inspection by a

phone technician would identify this.
