[GLLUG] Wifi router requirements for hosting Linux box on LAN

[James Roberts]

We normally expect to support ~ 10 simultaneous active users per typical 
mid-range WiFi box, maybe 30 connections in total. We would put in say 
1-10 boxes per floor, depending (in commercial premises - less in 
domestic, 2 cover my flat for example, each Cat6'd to the gigabit 
switch). But this is just for access email etc, NOT video or heavy 
streaming.

One client with heavy Spotify audio streaming for 30 users needs two 
fibre 80 Mbps just to support that :(

See:

For security we do NOT ever use permanent integrated wifi/router, AKA 
'single point of failure' ;)

We use fibre bridge supported by BT -

- pfsense on dedicated hardware

- then wifi network VLAN'd if necessary (usually not in this scenario).

For 250 simultaneous users - you will need better than 1 fibre connection.

So perhaps these specs are a bit overstated? How many actual 
simultaneous users?
