I just put it down to Abbotts 3rd world NBN infrastructure we got when he came into power. My area, we only have Satellite if your out of town or wireless if your in sighting distance to the NBN tower they erected on top of a hill over looking town. I've had shit/unreliable internet since I moved to Walpole. Have a neighbor who works from home who often has to go into town to use the CRC [community resource centre] internet to upload/download work stuff. Also only has 60gb limit on the satellite so when that's gone back into town again to carry on working.
I'm on wireless, just, have trees in the way, so I do get connection but not a good one. At least I do have unlimited download
3rd world African countries have managed to build better internet than Oz did.
