I have a Fritz box 7530 and a 100 k line from October. Will that be enough to run 2 playstations and netflix without stuttering?
That's enough.
And a 100 k line

Already good but the network provider will only guarantee you from his server.
Assuming that the Netflix server only provides you with 1 k, then the 100 k does not use anything, i.e. You can't sue network operators for it. This also applies to the Playstations because they will have third servers
Thank you for the asterisk ;-)
