I guess the question is what exactly we can do with 7 Mbps. Right now on the 5 Mbps package I can get full speed for well seeded torrents. But try downloading a single file from Microsoft downloads or iTunes app store and I'll be lucky if I get even 2 Mbps. Not sure where the problem is (i.e. Nayatel back end, or PIE or Nayatel local servers that service various sectors) but it's definitely not at Microsoft or Apple's end. This didn't used to be like this. I could previously get a single connection file downloading from MS at full speed but for the past weeks/months this doesn't happen. If you call their tech support, it's completely useless and they will try to get you to download multiple files from different sites simultaneously. In that scenario, yes you will get your bandwidths worth. Also 5 Mbps connection is useless for YouTube HD and I'm pretty sure 7 Mbps will be too. Most HD files just don't stream properly and stay stuck there, and for this one I suspect the fault lies at PIE not Nayatel.
So 7 Mbps is only useful if you are downloading lots of well seeded torrents or you are willing and/or able to use a download manager (not possible with stuff like iTunes). And it's quite unfortunate that they are obsessed with sticking at 1 Mbps for daytime no matter what. Here's what the Nayatel package will probably look like five years from now:
1 Mbps daytime
100 Mbps 8 pm to 8 am and Sundays
