let me spell it out - the levels on the SH can affect the quaility of the service - there is a range to the settings - outside that range and you have problems - you need a tech to sort it if thats the problem - level one support may or may not look at them - if they do they may or may not understand them - they have a belief that everything is wonderful in the world of VM and all problems are the users
so post the upstream and downstream levels
what other facts - its unreliable - what does that mean - wired or wireless - if its wireless then that your problem not VM's - they sell internet access to the modem WIRED - they provide wifi via the SH - if it works - great - if not - you solve it or come here and ask users [like me] for help
again a fact - which SH do you have
saying its crap or unreliable is meaningless - you want help or you dont - post facts and you will get help/input - continue down the route of VM are crap and you will get little to no input
