At my new house my housemates have signed us up with iPrimus because they have unlimited ADSL for $80 + bonus bill credit with no contract. However, it's awful. The router will randomly kick some devices off the network for a while, I have random slowdowns and currently I'm trying to watch a twitch stream while my housemate watches netflix and twitch just won't even load.
NBN isn't available in our area yet, nor is cable. What's a better deal than what we've got but will actually RELIABLY work?
So you're having router problems AND ISP problems? How can you distinguish which is which? Replace your shitty router first before going to the hassle of swapping ISPs.
