Maximum number of concurrent connections on Uverse 2wire

I have a question about the 2Wire Uverse Router and it's ability to handle several hundred people on a wireless infrastructure.

We are a church and pay for the highest speed business class Uverse and we have an HP MSM760 Wireless controller setup with 8-10 MSM 410 Wireless access points. During the week the speed of the network is fine getting around 12mb/down 1.5mb/up most of the time. But what we find is on Sundays when church is in session and people are using their portable devices on the WiFi for looking at the Bible and other things the speed comes to a grinding halt and no web browsing can occur.
how many concurrent connections can the Uverse 2Wire router handle?
Anyone have experience with this?

The 2wire can allow access to 253 devices
I would determine if the problem is a lan issue or web access issue



Need a business-class router, not a 2wire residential gateway.

The 2wire can allow access to 253 devices

To be more precise, the 2wire can allocate 253 IP addresses, but that does NOT mean that 253 devices may concurrently browse the web. 2wire devices have a small Network Address Translation table of only 1024 sessions. Whenever a device talks to the internet, several of the NAT sessions will be tied up for some seconds or minutes, depending on the type of traffic.

1024 NAT sessions was fine 5-7 years ago, but these days a single web page request may touch a dozen servers (images, videos, tracking cookies, ads, DNS, etc.), and each server connection requires its own NAT session. Multiply that with dozens of concurrent users, and everything grinds to a halt because the 2wire is unable to keep track of all the simultaneous connections.

There is not much you can do about this 2wire limitation. Even placing another router in DMZ may not not help much, because the 2wire's DMZ implementation still tracks NAT sessions.
