    How to tell if ISP provider is causing lost connection

    How to tell if ISP provider is causing lost connection 8th Jan 17 at 9:36 PM
    My router keeps dropping the Internet connection for say 5-10 minutes several times a day. Is there any easy way to distinguish between a fault in the router, my telephone line and the ISP provider which is BT infinity.

    What I was thinking of is a piece of software which logs when I'm connected and disconnected. Is it logged somewhere on my computer if it is switched on? My neighbour who has also got the same contract could do the same and we could compare.logs.

    It seems to work without denial if I run it as an administrator, but refuses to write it to any directory without doing this.

    I've not noticed any dropped lines since I've started running this. I have noticed the problem often occurs often after a period of not using the computer for a few hours, but it can happen anytime.

    a nice free program that does similar the the bat file is PingInfoView from http://www.nirsoft.net..

    As I mentioned earlier, check those nic driver verions and get the latest from the manufacturer.

    it could also be a bad phone line.

    It's been some time since you gave me this programme to run. Over this month I've had the computer on continuously, and not deliberately disconnected so I've just posted these results. Yesterday had the most disconnections since the 4th March. The longest I've ever gone without a disconnection is around 3 days.

    Would a LAN up, ADSL down be sufficient proof that it is a BT problem (something upstream of my router connection)

    ISP time. Hope you do not have a long wait.

    They will probably do a line test. too. When something like this happened to me it was a bad line connection in the box and the terminals were loose. the swing swinging the cables cause the disconnects.

    I've shaken the box, it doesn't make any difference. It's the guys fiddling about in the substation I wonder about!

    I assume you've checked the cabling and the ADSL filter/etc?

    My connection was playing up a week or so back, turned out my GF had been messing with the wiring around the TV and had pushed the ADSL filter up against a power supply adaptor for a TV box, I swapped the filter and moved it away from that PSU and no more issues. Either the filter was faulty or it was picking up interference from the PSU it was next to.

    It's worth as well checking the phone line as soon as your BB drops out, just dial 1471 and see if you get a clear sounding line.

    The real test is to remove the backplate on the BT master socket and connect the modem/router directly without any extension lines or phones connected.



    Regarding the script your using, it's similar to one I did some years ago, for shutting down Torrenting programs if my connection dropped (which kills my VPN).

    It's got a slight flaw in that the router will sometimes ping back on behalf of the external site your trying to ping out to, meaning it'll return a non-error state and the script will assume there is no issue.

    My later script is designed to be called from other scripts so it would do no good to post here, but the primary difference is:

    ping -n 1 -w 200 %hostname%|Findstr /I /C:"timed out" /C:"unreachable" /C:"could not find host"
    and the errorlevel check would be


    if %errorlevel% neq 1 (
    connect error commands here
    )
    It looks for all the possible words that would suggest a connection error and can't be fooled by limitations of ping.exe

    Off topic, but you torrent client should have a feature in it where you only connect to the vpn interface. Both Qbittorrent and Utorrent have this. On qbittorrent look under Tools, Options, Advanced, Network interface = "any device" is the default but you should select vpn inteface

    Now I do have uTorrent 3.3.1, but I haven't updated since I heard the later versions had been laced with adware/malware and bitcoin miners.

    I used Utorrent about 3-4 years ago and it was there, but cant remember the version, but failrly sure after 3/4 years it was under advanced?? I moved to qbittorrent and was happy

    possibly this, but at the time it was only one box - net bind ip?


    Google found me this for net.bind_ip and it seems to be the originating page of the pic above.

    A few weeks ago I finally reported the problem to BT around 9.30am in the morning. Their fault checking software managed to identify a fault on my line. Around 11am on the same day I heard a ring at the door, it was the BT Engineer!

    He found a spurious voltage, which he eventually traced to somewhere in the cabling out in the street which should have been affecting others (it wasn't). However after finding my BT box was still dropping out he replaced that as well. Since it was theoretically an outside fault there was no charge. So very good service overall! The only downside was that he couldn't find and fix a longstanding fault in my upstairs line which he disengaged.

    There have been no problems with the Internet since, so fingers crossed.

    Haven't thoroughly read this thread, but when you say your upstairs line, do you mean line or extension? If it is extension it could have been part of the problem.

    If you desperately need that I would suggest you look in your local phone book or business directory for an independent telecoms engineer. There's quite a few of us around, and we are normally a lot cheaper than BT for internal cabling problems.

    Glad they finally managed to (hopefully) solve the problem for you.
