Hi @kmmotahar ,
Sorry to hear you had some stife with your internet over the weekend. Did you take a look at http://agl.com.au/telcostatus to see if there were any outages affecting your local area?
Otherwise, your best bet is probably going to be to get in touch with support and walk through the troubleshooting process with them. If there's issues with your connectivity they should be able to clarify the cause.
