High Performance 3300 series in Netopia/Cayman

GoBG : Crap! My ISP has turn on interleave again......at a Depth of 352 on the downstream, with a 10ms delay

My first trace-route hop is over 50ms :(

The line is set where the DSL modem will sync at the highest possible speed.. which will in-turn enable interleave because of the line noise. And then the Dslam will lower the speeds to my 3meg plan.

It took me a year to get on fastpath after trying to explain what is was to my small ISP... and now its gone in a blink of and eye. :(

Here the stats on the 3347nwg-006

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

GoBG : After having these 3347 modems I can say for a fact they have a higher sustainable speed and better noise margins than the 2200 series.

$60 Including S/H, I probably could have gotten it cheaper. This was my offer to him. I needed to sweeten the pot for him to bite. The 5(bulk) for $200 adds up to $40 each.

Good luck ;)

I am looking for the covad 3347MWG-T (vgx)(California)
or the 3346N-002(i think all are generic netopia interface)

Re: High Performance 3300 series

Fri, 06 Feb 2009 17:58:00 EDT

GoBG : I sold the 3347nwg-006 prematurely, thinking the 3347nwg-VGx was an original, not a Covad. But I manage to buy another 3347nwg-006 on Ebay for $9 today :) Ebay is amazing!

After all this i'm making a profit!

Re: High Performance 3300 series

Thu, 05 Feb 2009 22:44:05 EDT

GoBG : I sold the other 2 3347 modems. I still want a 3347nwg with Netopia interface. The Covad is fine but I cant tweak or look at my online stats on it. So my adventure continues.

Re: High Performance 3300 series

Thu, 05 Feb 2009 19:00:24 EDT

GoBG : I got the 3347NWG-VGx today. It turn out to be a Covad modal.. blah!!

But I manage to update it with nta7.7.4r1 firmware. Everything works. It shows fastpath ;) But I hate covad interface. No advance options.

Re: High Performance 3300 series

Sun, 01 Feb 2009 11:35:17 EDT

GoBG : Update!

I puchased the 3347NWG-VGx from a guy that was selling them in bulk. Its was hard but he finally let one go!

Re: High Performance 3300 series

Sun, 01 Feb 2009 08:49:24 EDT

GoBG : I also won the 3347w-006 from a auction I bid on the other day.. figuring I would be out bid.

After learning it's not VGx base..and can't be updated do to its out of date wireless spec. I didn't want it. but you know how these auction things goes... you live by your rep.

I'm going to have a house full of modems next week.

Just bought the 3347nwg-006 off Ebay for $28 :)

Re: High Performance 3300 series

Fri, 30 Jan 2009 19:29:04 EDT

GoBG : I notice the 3347wg firmware starts with nl750

This worries me... It may not accept nta firmwares like the 3347-02-1006L. It had a firmware that begin with nwta and wouldn't accept anything else.

It seems I'd be better off just getting a 3347nwg-006... I know "but its bellsouth" The 3347nwg-006 is the only one I know for a fact that will accept nta firmwares and the bellsouth GUI can be disabled by turning off auto config via telnet.

Re: High Performance 3300 series

Thu, 29 Jan 2009 22:55:42 EDT

GoBG : I think I will bite the bullet and buy another 3347 modem..I won the 3347-02-1006L on ebay for $5 so i'm not upset, only disappointed I cant get rid of the bellsouth firmware.

I see a used 3347WG for $40. I don't believe 3347WG's has any ISP interfaces.

Re: High Performance 3300 series

Thu, 29 Jan 2009 16:42:50 EDT

GoBG : 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.

Re: High Performance 3300 series

Thu, 29 Jan 2009 12:45:49 EDT

dgilbert : 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.

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 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.

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?

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.

I originally tried netgear because my Dslam use broadcom equip which the netgear has a broadcom chipset. I read its good to have matching equip with your ISP. Netopia/Motorola uses Texas Instruments. But their new 7000 series uses broadcom, its VDSL though.

I sync at higher speeds over the 2246N.

A lot or a little? What do your line stats look like?

Assuming you are connecting in ADSL2 mode rather then ADSL newer protocol allows finer grain control over low level modem overhead. It is common to see small differences in sync rate.

If prior modem or DSLAM line card only supported ADSL and now both ends support ADSL2 connection will use new spec. It provides slightly better performance over long circuits.

Unless margin is low sync rate should not be affected by modem. Sync rate is set at DSLAM based on service plan ordered.

Router processing power does come into play with high speed connections as NAT requires a lot of housekeeping and large NAT table memory is important for P2P users.

GoBG : For the most part that's true but I once tried the netgear DG834GT and I sync at higher speeds over the 2246N. The modem chipset does effect line condition stats as well.

This was one of the reasons I asked does the 3300 use higher performing processors over the 2200.

Re: High Performance 3300 series

Sun, 11 Jan 2009 14:17:49 EDT

GoBG : Thanks for the replies guys. I have a 2246N-VGx(lastest firmware) right now and was wanting to know if I would get any real world benefit if I were to move of up to the 3300 series.. i'm talking better Noise margins and Attenuation.

3300 looks like a big ole hefty modem/router lol that would seem pretty stable and powerful.

I can get the 3347wg for $45 and wondering should get it.

jimbopalmer : AT&T (nee' BellSouth) gives business customers a 3347NWG that can be a IPSEC VPN end point. If you are a multi location business that can be a desirable feature. (I use 4 of them as spokes to a VVPN hub)

dgilbert : just a few more features. sync speed is going to be determined by the DSL you have and line conditions. goto netopia.com and compare the model you have to the 3300 you desire.

GoBG : Netopia/Motorola don't go into detail what this means over the 2200 series..

Other than added GUI features what does the 3300 bring to the table in terms of actual bandwidth performance? Do they sync at a higher speed? Better processors?
