Strange problem with Internet disconnection

All,

I hope that this post will induce some smart replies as I am really puzzled with this problem .

I was trying to help out a friend with his internet connection.
He is using a T-DSL 1500 line and a D-Link 624 WLAN router and one of them cheap Telekom TELDAT modems.

The problem is two-fold:
1. The Internet connection seems to disconnect every once in a while, sometimes as often as every hour (no relation to other line activity, i.e. incoming calls).
2. #1 would not be as serious, only that you must power-cycle the modem before you attempt to reconnect, or the user/pass will be rejected by the server. I had to set the Router to manually connect otherwise it tried endlessly to reconnect and Telekom would shut down the account due to repeated password failure (they block at 9 failed attempts, it seems). I had to power-cycle the modem before letting the router dial again, which is really strange.

As you can imagine, the above scenario results in my friend having to access the HTTP page for the router and connect thru there, manually, after resetting the modem upon every disonnection. This is really awkward.
Needs to be mentioned that this behavior was occurring even before installing the router (stand-alone modem configuration), and is now taking place regardless of whether he uses LAN or WLAN on the router.

I had a T-DSL line myslef for a year, before switching to Alice, and never experienced any disconnection other than the routine 24 hour IP re-issuing with both companies. Let alone, I never had to reset my modem to remedy rejected passwords :excl: .

My personal guess is that something is wrong with the modem, so I may try to replace that, but I still can't figure out howcome the modem passes on faulty user/pass to the network leading up to the account being blocked every time.

Any similar experiences or tips?

Thx,
Gil.

I would also say it was a fault with the modem. Have you tried a hard reset ie. back to factory setup then configuring all again...
Otherwise try and get another DSL Modem to try out...

@ gil b: I really could recommend bbulldog for computer problems !
He saved ours as well and brought it back to life. Thanks again, bbulldog

Hubbi, does bbulldog make house calls?
As I wrote, it's not even my PC so I don't have the opportunity to fiddle with it.
I was just trying to see if someone else experienced the same problem and offer a quick fix.
If nothing comes up over the next few days, I'll try to replace the modem.
Strange problem, though.

Thanks.

If it wasnt so far away then yes

I have the same kind of problem with mine, although I blame it on AOL. I get disconnected frequently and when I want to reconnect I can't. Sometimes the laptop won't even shut down.

Apparently, a lot of AOL users have this problem here and abroad.

So we see bthat AOL are every bit as bad as their reputation!

Why continue with the torture? There are enough providers out there.

At the time, AOL seemed a good option. I chatted to someone when I was back in the UK over Christmas and as soon as I mentioned the problem, the repsonse was get rid of AOL from your machine. He mentioned something about "Shell files", which rings a bell when my laptop crashes.

From the post above, If your provider is AOL, I would suggest that your modem or router is fine. We changed our router too and the same problem still occured.

My opinion, I would not recommend AOL even if it meant saving a few euros every month. I will now be looking for a new provider.

That is a problem you get with a provider's proprietary internet front end, typically AOL, but also the T-Online software can present the same problems with modem connections.

If you have a T-Online account, you can dispense with their software and log directly onto the server in the same manner as you would with another provider, which will cure the problem. I don't know that you can do that with AOL, I don't know if still you have to use their software to use their service with a DSL modem.

AOL have nowgone accross to Router/Modems so you dont have to install the software, so far as i have heard. If anyone asks me to check problems with internet and they have AOL i keep well away from it and tell them the same, change the provider!

Says it all I think

Has your friend tried the connection without the router, with a PC directly connecting out through the Teledat DSL modem? The PC needs to be setup to make the PPPoE connection, login, etc. With this setup, it may be easier to deduce the reason for the disconnections.

If using T-Online, there is a test program that you can use to check the line functionality, settings, speed, etc. I think this can be run from T-Online DSL-Manager but I am at work so I can't check.

I have a spare (and working) Teledat DSL Modem (with an Ethernet connection) and live in Griesheim near Darmstadt.

My friend had the Teledat connected to the line directly before I installed the router for him. However, he had the same problem then and was quite accustomed to pressing the on/off button on the back of the Teledat to resolve hiccups with the connection

To answer questions in previous posts, I never touch those apps from T-Online or AOL, so there was only a simple DUN connection with the Teledat earlier and now a PPPoE connection with the router.

I believe the T-Online software page is this Downloads but I couldn't find anything interesting there. My German skills are however nothing to be proud of

I should have a spare modem myself (got to dig it out of the cellar), which I intend to try at the lack of a better idea, but thanks for offering yours!.

ftp://software.t-online.de/pub/service/to...Manager_6.0.exe

This thing has a Verbindungstest to test connections...but it is in Deutsch.
Interestingly, it does not require the T-Online software or DSL drivers to work...

hello gil_b,

my setup at home is more or less the same - d-link 614+ instead of 624.
i am useing the "old" telekom dsl modem which is purely a modem that you then connect to your network-card or router/switch, this keeps the dsl-line permanently connected and that is the way it is supposed to be, the router will only connect/disconnect your actual account with t-online or whoever.
is that teledat thing also just a modem (e.g. teledat 302) or is a tel/isdn combination? if it's just a modem it should keep the dsl-line permanently
available if not the modem or line is faulty. a friend of mine had a similar problem
and in the end he just changed all network cales and that did the trick, one of the "old" ones must have been "paired" differently.
might be worth a try?
cld. you post the teledat model/type maybe i can make a suggestion then.

Thanks jg for posting the link
and thanks Charlie for the tips

charlie- the teledat is just a modem but I don't recall the model number

I guess I'll have to go thru the cables and modem to find out what's going on

BTW: while looking at the D-Link website for f/w updates, look what I found creeping up into the release notes (in red)...
This may not be the right f/w or model that my friend is using, but it blows my mind to see that these issues could potentially be resolved with a f/w update on the router of all things...
could it be that this is all related to some problems with the router?

V2.20cm (3.20cm)
Locks the WAN port to 10Mbps.
* Use only if having connection issues with your modem.

V2.30 (DI-614+ RevA only):
Fixed the DVC-1000 special entry in virtual server
Fixed PPPoE bug

I have a similar problem and used to spend ages swearing at the computer until I started using firefox and downloaded session saver. Now when the connection goes I can return to exactly where I was before. It doesn't address the root cause of the problem but it saves a lot of hassle when reconnecting.

hello gil_b,

if the problem also occured while you connected thru the modem directly, and is still doing the same thru the router then i don't really think a f/w update will help.
(a f/w update is still worth doing)

the dsl modems normally have 3 green lights showing if the dsl connection
is working - 1 is simply on/off, 1 shows if the network-cable is connected to a pc/router, and 1 is for availability of the dsl/line -this last one normally blinks
red for a while when first switched on until the modem has established a line -
try disconnecting the pc/router completly from the modem then restart the modem and wait for the line to connect, now wait and see if it disconnects whithout any pc/router interfering - if it still looses the connection then it is def. the modem/cable/line.

Ever since I bought a Cisco ISDN router I would never install any kind of dial-up software on my PC again. Buy yourself a box that does it for you and connect to it via ethernet or wireless. I now have a Linksys WAG354G HomeGateway down in the cellar. This acts as DSL modem, router, 4-port switch, wireless access point. Installed it in about 5 mins about 4 months ago and haven't touched it since. Can access wireless or wired in any room. No software installed on PC to screw things up. All you need is an enabled ethernet port or WLAN card.
