Been with them for 3-4 weeks now. Here are some of my thoughts and experiences so far:
1. 6pm onwards I'm getting ~5mbps where I'm paying for 25 (I'm not even a downloader) so it's not like I'm abusing the network.
2. The routers they provide don't have dual band, so no 5Ghz wifi. Getting pathetic wireless speeds on 2.4GHz most probably due to overlapping channels, and there's absolutely nothing I can do about it. For such a hefty installation fee, you get very little out of it....
3. As per Greencom agreement, you don't have access to the routers they install. So setting up policies such as VPN, QoS, Bandwidth shaping, or even just troubleshooting is a no go. Vox gave me a router with all the bells and whistles i.e dual band, AC, DSL(not that i need it) and WAN ports, and the rights to configure the router however I please. From my discussion with the technician that "installed" the router, he made some condescending statement that people don't know anything about networking, and so they end up "breaking" things. This is most probably the reason why they prohibit access to the equipment. Sooooo i guess I'll have to get my own router, have them configure a route to mine, so that I can manage my own network.
4. Their support. I'm currently experiencing terrible download speeds in the afternoons (might be related to point 2). The issue is that they would ask you to do something like a speedtest, or whatever, via their ticket system. Then they don't interact with the tickets at night. So any normal person that works at office during the day, wont get to perform the tasks as requested until they get home, at which they won't be replying until the next day. Essentially, this means that your issues might stretch on for quite a while.
On the bright side, you get "unshaped" and uncapped at a great price. ¯\_(ツ)_/¯
