Re: [DSL] Modem Poisoning
5100(b/a)? not absolutely sure, I'll check at lunch
The connection in the 40-60 range I don't know. 60-80 do die but it its sort of random. 200+ is guaranteed a quick death thats why I mentioned it. 24 is fairly stable.
I haven't done any testing with ACK prioritization on/off since I thought that PPPoE was the major resource consumer. I will start now test it too.
If the speedstreems are connection limited from ACK prioritization (and the limited resources that it consumes) Do ADSL modem cards (PCI?) have better performance since they can use the full system resources? Can the use the full pc system resources?
So if I offload the PPPoE and ACK prioritization, off the modem to a third box "PPPoE Server", and have the Modem in bridge mode, my problem might just go away? |

2 edits | Nope I checked again they say just "5100", no A or B seen on the back.
What is meant by the term Generic Firmware? I assuming you don't mean the original factory Firmware. I read many posts that mention it in passing. Do you really mean 3rd Party Firmware, or non-provider branded firmware.
I'm wondering if ACK p could be turned off via the CLI command?
•Note: I'm asking about Firmware, not for Firmware

The load balancer's nat table may be able to handle the many connections |

Reno, NV | Yes, normally these modems simply crash or reboot or drop sync when they have too many connections. |
