I finally got around to upgrading my old linksys WRT54G

Wow, I am assuming this is an internet service provider since I don't think much else would need that kind of bandwidth.

How many people run through that thing ?.

That thing has to be good for at least 180,000+ residential subscribers.

Lets see....in its current configuration, it can support 140Gbps per slot, and there's 16 slots per chassis.
If we keep it simple and say that we'll use 50% for input and 50% for output, that's 2.24Tbps/2 =1.12Tbps of capacity.
If we follow the general rule that only 10% of the network users will be using the system at any given time, and we want to offer 50Mbps to each user....that's around 220,000 users per CSR3. If we wanted to get crazy and offer 100% guaranteed bandwidth to every user, we could support 22,400 users per chassis at 50Mbps to each user :-D

If you were offering 10Mbps service to each subscriber, you could see 1.1 million users per chassis, fully loaded.

Am I the only one that found irony in quoting the op only mentions a wrt54g?
