Internet Keeps going offline for a few mins - NB, Problem has returned - Page 12

Well, the engineer came... take a quick look at the power, said it was OK, and then said he couldn't do any more.

NTLs system upgrade this weekend means that he couldn't try a new cable modem... so overall, that was a complete waste of time.

Now, my downstream signal level, as reported by DocsDiag, is currently -4.3dBmV . As far as I'm concerned, this is *too low*. But how can you argue with a man who's job it is to test that?

The SNR is also a bit too low at 26.6 . Furthermore, I'm getting uncorrectable codewords at a rate of 100 a minute.

It's just a bit annoying that when the system upgrades are done, I'm going to have to ring NTL again and get another engineer out to try a new modem.

As I've said in another thread, this has started yet again. So may as well resurrect this thred also.

Never stopped for me. Aparently there's something in the range of 70% packet loss on my line.

I was ment to have another engineer out on thursday. Did he turn up? not a chance...

Earliest time I can do again is *next* thursday. All the while i'm paying for a faulty line.

Just lost my connection for a few minutes... Stockton-on-Tees

(has been happening noticably for around a week now) - rebooting the cable modem seems to sort it for a while.

Kinda funny but, its back but not as bad as before.
Current symptoms

1. all downloads seem to drop and restart after 40 or seconds, http and ftp
2. online games dont disconnect me, but sporadic spikes occur, (no data , then all of a sudden everything on screen goes crazy till it settles (as it dosnt d/c me i have abused these spikes

)
3. Very often web pages refuse to load depsite page refreshes, then for a few mins its ok , then back to a "waiting for website blah blah blah msg"
4. If i try a different web proxy I get no connection at all. (is there some sort of auto block on specifying other proxies?)
5. Certain sites seem to have given up alltogether, i.e geocities hosted, and a few cd burning related sites like afterdawn and cdfreaks ( is this a filter?)
6. Streaming media never plays smoothly, even on 128kbps settings, (i have 750 kbps) to many reconnects to make it worth watching

all the time, cable modem connection light stays on, and the data light seems to flash a hell of alot.
Yes I have virus and adware scanned, all clean
Yes all Windows updates are applied.
And yes same setup that works fine, 60% of the time, then gets these rather annoying service problems.
And No ,not called cs yet, I was kinda hoping it would resolve automagically as before.

Nopcode...

I'm getting some of this in the Reading area .... in particular I am finding your number 4 'proxy' a real issue. For some reason some of them will refuse to work at all - this is a new problem since I used to be able to put any NTL proxy in from one end of the country to the other and would get results.

Anyone else seen this specific issue ?

Yesterday it was alright, played online games for a good couple of hours and not one freeze. Then just had a 20 minute session and it froze 3 times again. A couple or three times while its been like this since friday, I noticed it froze the moment I pressed the mouse button to fire. Now that is some amzing coincidence or something to do with upstream traffic as far as I can tell. Doubt it is my pc or software as it is this thread is testament to the number of people it affects, and also I've reinstalled windows to try and get rid. Will ring cs in the morning. What really annoys me is that we are no nearer knowing what the hell is causing this in the first place, and why does it magically fix itself? To me this is looking very much like the service in my area is becomming oversubscribed. Well whats the point even having the service if it can't be used for what I want most, which is online games. Losing hope here.

ntl have changed the format of (some of) the proxy names. It could be that the ones you are trying are now in the new format.

List of "old style" proxy addresses:

Nah, that's alright sir, -4.3 is workable.

That on the other hand is a bit dicey and will be the source of your codeword issues and probably the packet loss too

. However I have a feeling that the SNR on your upstream is actually far worse and is probably the source of your problems, either SNR or return power issue.

Yeah, most likely. I should have an engineer coming out tomorrow... hopefully he'll be able to do more than the last time. I think it's probably the modem to be honest... it's an ancient terayon.

Its been abyssmal in Scunthorpe tonight for me. What I seem to have noticed via playing CoD, is that when the problems occurs, which was a good every 3-4 minutes tonight, all upstream traffic completely stops and downstream traffics slows to an absolute crawl. That info of any use? Old Terajet210 modem here also.

Some problems to consider are:-

a) you have a virus or spyware on your system
b) you may have interference from your firewall
c) your modem has problems.

Try the pcpistop site and/or the symantec online scan which will test your machine and may provide a few clues as to what's going wrong.

nopcode · 24-09-2004, 00:14

funnily enough, i have a terrajet too

No viruses found, problems even when firewall is disabled, (using msconfig to disable too)

I heard from time to time they push newer firmwares out for modems, could this be related? either its not being recieved properly (causing reinits) or maybe we need one? lol

btw. I tried other new proxies as mentioned earlier, pages load faster, but still get the "freezes" and have to refresh almost every other page to get it to display
