@Sunshine 

Thanks for the reply.

 

Answers are:

 

FIRST I do save the log file(s), but there are so many messages about the IGMP  issue that the log files are filled within minutes, and so the data about disconnection is lost.

If the details about the disconnection were present I could live with the IGMP messages. There needs to ba an "Exclude IGMP messages" option.

 

1. I believe that all devices lose their Internet connection at the time of router disconnection, BUT, because the System "DSL Down" message is never captured (see above) I do not know the exact time that the router disconnects. (EDIT: The "DSL Down" message is never captured when the IGMP message problem is present. Otherwise it is captured.)

 

2. Generally I have not seen any difference in the LEDs, but the router is in a cupboard with the rest of the network stuff, and is not in clear vew.

 

3. The router reconnects automatically, usually after a very short time. When it disconnects in the absence of the IGMP issue it often reports.

    Here is an extract from the Log, at a time when the IGMP issue was not present, and all messages were being recorded properly:

      2023-05-14 00:53:33 [5] System: DSL Link Down
      2023-05-14 00:53:36 [6] PPP: Terminating on signal 15
      2023-05-14 00:53:36 [6] PPP: Connect time 821.5 minutes.

      2023-05-14 00:53:38 [5] System: DSL Training
      2023-05-14 00:53:40 [6] PPP: Terminating on signal 15
      2023-05-14 00:53:43 [5] PPP: Connection terminated.
      2023-05-14 00:53:43 [5] PPP: Release PPP unit success
      2023-05-14 00:53:43 [5] PPP: Modem hangup
      2023-05-14 00:53:59 [5] System: DSL Link Up us/ds 0/32398 kbps Type 64/65B PTM Annex B

You can also see that the speed is quite a lot lower than my contracted maximum speed (56Mbps) but I am taking that up withy my ISP.

The reconnections since April have shown a marked decrease in speed:

      20230419:04:23.47 DSL LINK UP               at 44974 kbps

      20230422:05:51:00 DSL LINK UP               at 44780 kbps

      20230424:03:07:00 DSL LINK UP               at 39999 kbps

     20230425:02:11:15 DSL LINK UP               at 34999 kbps

     20230514:03:40:35 DSL LINK UP               at 32398 kbps

     20230515:03:25:11 DSL LINK UP               at 29999 kbps

(NB.: these figures have been copied from the log files into a report which I am producing to send to my ISP. But I guarantee that they are

exactly the data shown in the log after the disconnection and automatic reconnection.)

 

4. I will do that: I do not however reboot the router routinely because it automatically reconnects.

Note that messages logged preceding and following the disconnections are completely normal and I have therefore not included any.

I never reboot the router after a disconnection, as reconnection seems to be automatic and quick - as shown in the above log extracts.

I will do that. I did wonder, however whether a router reboot clears the IGMP issue, as after a reboot that ceased. It will restart again at some point, however.

 

5. My ISP is PlusNet.. The connection details are: VDSL2, Annex Auto, PPoE.

    In case you are interested, here is the status current report:

	Upstream	Downstream
Current Rate (kbps)	9630	29999
Max Rate (kbps)	9615	55959
SNR Margin (dB)	6.4	12.2
Line Attenuation (dB)	6	18.4
Errors (pkts)	57	0

 

Thanks for your help! Sorry its a long reply!

Hi, when checking the system logs, you could save the log file, even though there are many logs about the IGMP Warnings, you are still able to check all the other logs to monitor the internet connection.

 

Besides, regarding the daily disconnection, please help to confirm the following details:

1. Will all client devices lose internet at the same time including wireless and wired client devices, or only random wireless client devices disconnect?

2. Is there any changes on the LED when the issue happens? especially DSL and Internet LED

3. When the issue happens, will it recover automatically in a few seconds or minutes? or it only recovers after a reboot?

4. When the issue happens next time, please don't reboot the modem, login the web interface, share with us screenshots of Advanced->Status page and the system log file.

5. May I know who the ISP is? and is it ADSL or VDSL line?

Thanks for the suggestion of installing a Syslog manager.

Unfortunately this would not resolve the basic issue.

 

FEEDBACK (provided fot the attention of TP-Link designers)

As an experienced user, and previously a professional web and software designer,

I find that the logging support of the VR2100 incomplete and unsatisfactory.

Rather than make a series of extensive comments on the Logging system, might I

suggest that a designer examines the System Logs of a Netgear Router such as

the VWNR1000v3.

Its reporting of remote connections, and most other activity is far more accessible

and complete than that of the VR2100. Furthermore it does not require the

purchase of additional software to complete missing functionality in viewing the logs.

There are other improvements which could be made but I suspect that designers

operated under the old adage:

"Just like a book, software is never completed, merely abandoned."

 

You may close this thread as I cannot quite see that the issues which I have raised

will be resolved, but I do thank you for your prompt replies and attention.
