Hi Barry,
I now appreciate what you are saying in that you have both a fixed line ADSL service
and a wireless (guessing 3G) alternate service but both are flakey.
Is both the ADSL service and 3G service by the same provider (e.g. Telstra) or are
they different providers?
I hear what you are saying about the exchange and it could be that your wireless
connection goes back to the same exchange, but it would not surprise me if
they are handled entirely different at the exchange level. For example, your wireless
connection has to also communicate roaming data and so on across the network
so you would think where the ADSL network data and 3G network might get
multiplexed down the same fat pipe, it would be way at the back of the exchange
and that if it was congestion there, the whole local mobile phone network
would be dropping out as well.
So it probably is either two problems (i.e. a coincidence) or if they share the
same provider and the same account, a common configuration problem.
We have experienced ADSL outages where the DNS (servers) have gone offline now and
then. In our case the DNS (servers) are apparently up in Queensland. But when that happens
and you call the provider, they know instantly what is happening as everyone is experiencing it.
On one occasion we did experience outages that were configuration related at the
provider level. Somehow they had two different users contending with each other
by a configuration fault that might have been at the authentication level.
One thing I always find handy is to keep a list of known IP addresses.
Not all servers respond to pings but keep a list of your own gateways IP address,
your DNS IP addresses and that of say bunnings.com.au and a few others
both local and overseas.
Experiment before it goes out by entering the IP address for say bunnings in the
URL entry line of the browser (113.20.129.146). Does it resolve to Bunning's web site?
Try pinging the IP address and then try pinging bunnings.com.au
Try a few others and keep in mind that sometimes companies change their
IP addresses so don't count on the same IP address being valid a few months
later in all instances.
If it responds to the IP address but not to the URL, it will be a DNS issue.
Good luck! When it isn't a hard fault they are the worse to track down.
Best Regards
Gary
P.S.
Though the contents of the local exchange have no doubt been updated from
Mr Hamilton's day at Mt Kuring-Gai, dare say the copper cables
that run from the exchange to here are probably the same ones.
As I have posted on this forum before, I have some fragments as a souvenir that the Telstra
technician gave me last year to point out that they are falling apart and he
encouraged me to show anyone who wants to debate that the NBN FTTH approach
is not the best one.
He told me he was looking forward to re-training for fibre and saw it as a great opportunity.
