FWIW - IP Changes....

Hi Dee... I haven't done it for a couple months, but for a while I was moving 20-36Mb files via ftp protocol quite often (video on adding airhorns to motorcycles). I must have up & downloaded the files maybe 10-12 times, and I never had a disconnect.
I know you don't have a USB modem, but on the one system you have, have you run any online diagnostics, to check out error rates during this upload? That might shed some light on the problem if you had high error rates or retrys.

On IRC, forget it...I'll go through 50 IPs before the file is complete (nightmare), if someone is downloading from my FTP, they will go through several..... Only *ONE* time was I able to send a FULL large file to someone else (using FTP client) without a disconnect...

Btw 20-36MB is small for me (they are not the problem), so we are not quite in same ballpark. Try sending a 700MB file, and let me know how many times you disconnect? )

Btw , Tweak Tester II says fine....no packet loss, 100% efficiency...

If you are FastPath, then you might want to change to Interleave. Interleave has more error correction than Fast and will result in less dropped packets. I suspect that dropping IP's isn't so much the problem as a symptom of a marginal line issue which is causing your PPPoE tunnel to drop, thereby garnering you a new IP when it re-establishes.

How do I change? A request to Ameritech via phone?

That should to it

Hi Dee!

I may have been experiencing the same problem! Let me detail:

Yesterday a spider from search.aol.com started indexing my church's website (which I host). It banged away for a good bit, then I crashed and changed IPs. The one thing about a spider -- it's grabbing things at a high rate, and doesn't let up.

I'm suspecting the Linksys now -- my operating assumption is that it gets flooded with traffic (especially on the LAN to WAN link), it'll buffer for awhile, and then just fall apart.

I set IIS to max out bandwidth at 128Kb/s, and I'm going to beat on it today to see if it'll fix the problem. If my assumption is correct, I shouldn't be dropping my IP.

Anyway, if this turns out, I'll let you know!

I responded to an old posting of mine (5/28/01) on this issue, just to bring it to the top. See "Loss of Sync on large uploads"

Dee, you've passed over 2.3 GB of traffic since 7/25......stop trying to download *the* internet

hey If I could download the internet I would. hehe

Yeah well at least you seem to have the free time to

Dee, you can blame me for your line going down, but you're on interleave now...good luck.

It ain't the linky, i wouldn't have done it if the line stats were fine.

reply to toolkit
Ok, I hope I dont get flamed here. I have the same issues with the dropping of PPPOE connections...and basically getting a new IP address something like 8 times in an hour.
I am running a Linky as well, so I dont use that crap software that was given to me by ATech...but there are a few things in this thread I dont know about. Can someone point me in the right direction here?

What is Interleave, and why would I change to it? And from what am I changing from? Whats FastPath?

I have had the dropped IP address thing for a month now.
Never an issue before that, in fact my line was strong and fast. I have not been downloading anything huge...just typical email,surfing, and a little dev work of my servers.
I'll do an analysis of my traffic when I get in today...if my line is up

reply to Dennis
2.3GB? That is all? You sure that is right? I would have expected more like 5-6GB, LOL )

Ok, I'm on interleave now? Ok...I will try that out, and let you know how it goes....thanks dslknowitall )

reply to AS400Dave
AS400Dave, dslknowitall put me on interleave....hope that helps or works out problem. Thanks for the info, and let me know what happens with your changes

reply to toucansam$
touscansam, thanks much But, I am too lazy to dig for it since dslknowitall said Interleave may solve the problem. Was that your resolution? Or did you find a work around? Care to share "Cliff Notes" version of what happened in May?

thanks again

Dee

reply to PyroVolley
Pyro, I don't believe I know the difference either I am just trusting dslknowitall since he thinks being on Interleave may solve my problem with uploading and losing sync all the time..... I hope he's right

Maybe someone else will come along and explain pros and cons of both......

Dee

What is the difference between Interleave and Fast line profiles?
Interleave is a more robust, fault tolerant line shaping protocol. It has much more error checking than Fast and is packaged to be as impervious to noise as possible, at the cost of increased processing and latency. Fast is considered to be delay-sensative, yet noise tolerant. Fast data operates about 10 times faster than interleave data (2ms for fast, and 20ms for interleave), but will generate excessive CRC's if the line is even borderline in terms of "cleanness".

thanks dslknowitall In speed tests, Interleave is a little slower getting out the gate, but really no noticeable difference from Speakeasy or DSLR speed tests. I can deal with the higher pings if it means keeping sync during hefty uploads (smile).....

thanks again!
