Re: High Performance 3300 series said by tranle:said by GoBG:A little.. nothing game changing as I remember. I just looked up the CPU on both the 2200 and the 3300 and they're the same. I guess the "High Performance" Netopia/Motorola mention is more to do with software. ... It has to be more that just software because I am currently using a firmware for the 2247NWG-VGx on my 3347NWG-VGx. Just because the newer version has dsl line statistics entries that the older version did not have. Is that safe? To swap different series firmware like that? Would it work on the 2246N-VGx?
So the firmware in the 2247NWG is more up to date than 3347NWG? |

I have been using the nta774r1.bin in my 3347NWGvx since around 02/08/2008. It does somehow check that it is compatible with your hardware, because I did try a firmware that was not an ntaXXX.bin and it would not take it.
I had reported some bug on nta760r4.bin but netopia never bother putting out a new version on their website. |

What's your SNR Margin are like? |

Post your stats davidg.
One thing I notice is the netgear broadcom modem I tested had upstream SNR margin at 16db. This tells me the broadcom chipset handles line noise better.
But the 3347 does have broadcom switch integrated with Texas Instruments chipset..»wiki.openwrt.org/Hardware/Netopia
Perhaps this is the reason for the higher upstream you posted, tranle. I don't believe the 2246N-VGx has the integrated broadcom switch. |

i had to put my 3547 back online. for some reason teh 3347 keeps locking up every night and requires a HARD restart to correct. i ain't got time to play with it right now, so i am just using the 3547 until i get time to see what the problem is. the 3547 is getting slightly slower thruput due to teh reduced SNR, but i can deal with it for now.

2 edits | The 3347 I have is fine so far... but I hate seeing the word "interleave" on my stats,  even though I don't believe i'm on it do to my first hop stats.
You won't believe what I went through to get fastpath from my small telco. It took over a year and a call to the ceo.
The 3347 does have better upstream SNR numbers than my old 2246. Decision Decisions Decisions
If only I could flash the 3347 with a Vgx firmware.. I think that would solve it. The bellsouth firmware what's causing this I bet. |

I see the 3347nwg-006 added a few feet to my loop length.
Since its the same hardware..(minus the bellsouth firmware) the stats are pretty much the same.
What we learn?
The 3300 series with the integrated broadcom chip has better upstream s/n margins than the 2200 series |
