My broadband went down last Wednesday at 2.45am.  Since then I have spoken with 10 different techies at Vodafonre and spent 6 hours on the phone trying to fix my connection -90% of that time was spent waiting for calls to be answered.  My router gives me a green stable ADSL light (Dynalink) but I can't authenticate.  Router constantly says establishing.  I've been told it's a tunnelling issue?, and had this fixed.  I've been told it's a port issue and had this fixed three times.  Each time I get ~2 hours worth of connection before it goes out again.  It's now nearly a week.  I've bought a new Linksys router -same issues.  Vodafone have twice told me a technician will be sent out to fix things up -no one has turned up.  My wife's stayed home from work waiting on an assurance someone will be out.  I was down most of Sunday (like everyone else) but only got my connection re established for a couple of hours last night.  I'm now really wild, but don't seem to be able to convince Vodafone to fix the problem properly.  The last tech told me I'd have to pay $81 for someone to come out and fix the problem.  Been an IHUG customer for 10 years and never had this put on me before.  Rung telecom and they've done line checks.  All OK.  Tried three different PCs on two different routers -same problem.  Have you experts got any ideas or advice?  Don't tell me to change my ISP -I'm already considereing this, but until e mail portability comes in I'm not keen.  Thanks.
