HN discussionI think the idea is that many wifi networks out there require registration/payment to use. They also do this in really, really weird ways because making stuff is hard. Some of these only work by capturing http requests and rewriting them to take you to their portal. Funnily enough, that and other methods often work very badly and so you might be left trying to visit a site getting timeouts. Maybe your browser visite…

HN discussionIts true that the specs are not symmetric in ADSL. The CO (Central Office) end is different from the CPE (Customer Premises Equipment) end, and two CPE devices cannot talk to each other. Among other things, the engineering work had to take into account that at the CO end a bunch of wires would come together and leak RF between each other. G.SHDSL is more common in a 1:1 configuration (although I think the ends may s…

HN discussionYou should follow Adrian Kennard's blog: http://www.revk.uk/ He's the CEO of AAISP, arguably the best and most transparent ISP in the UK (also quite a small one). On costs, there's also contracts with other ISPs (most lines are leased from other ISPs, not leased by the ISP itself), customer hardware (routers and other gadgets), marketing, support, subcontracts for personnel across the country, etc.
