This is really a last resort, to pick your brains before contacting Chorus.
Basically, switched to NOW (formerly Airnet) on a Naked DSL plan, using our old-faithful Dynalink RTA1025W, and got a 4Mbps speed increase, and nice little 16ms ping to Auckland (previously 35+).
Purchased a Netgear DGN3500 for gigabit and Wireless N capability, all seemed ok.
Moved computers into a different area of the house, and had the closest jackpoint wired up as the primary DSL port. DSL drop outs started, ping to Auckland raised permanently to 35ms+, can no longer stream 1080p without constant buffering pauses, and 40% of the time when surfing I am presented with "Page cannot be displayed" which is rectified and loads successfully after a retry.
Got some guys round to take the black cable, directly from the demark, underneath the house, directly into the closest jackpoint. All other jackpoints disconnected. Still dropping DSL ~10-15 times a day, and sometimes just PPP.
Figured it was the new DGN3500, so went back to the RTA1025W. Nope, still dropping, but not as much as it was with the DGN3500.
I have tried:
- Upgrading firmware on the DGN3500.
- Tried with and without filters (multiple).
- Changed BT to Router telephone cable.
- Changed Ethernet cable from CAT5E to CAT6 from PC's to Router.
- Updated and tweaked network adapter settings.
- Established ideal MTU, and set accordingly in the routers.
Here's the interesting thing... sometimes even the RTA1025W router won't respond, and provide me with an "error 400. Bad Request. No request found", and I even get "Page can not be displayed" on the DGN3500 - just when browsing their web interfaces.
So many factors, so many variables, it's labor weekend and I'm doing my head in, so I appreciate any feedback about anything else I've missed, before I go calling in Chorus to check their network.
