    Unhappy I tried the method by the guy two floors above me on the page

    I followed him, entering the DNS manually, still no luck. No the internet for wireless always disconnect and devices' network speed is ridiculously slow at some points. Need HElP!! C3150 archer right here.

    Select advanced tab
    Select internet wan interface tab
    Select editing of pppoa_0_38_1_d
    Expand 'advanced' at bottom of page
    Tick 'Use the following DNS Addresses'
    Enter your ISP's primory and secondary DNS servers

    e.g mine are: https://dnschecker.org/dns/United-Kingdom/TalkTalk

    Once DNS servers are entered the basic page setting will show 'Internet connected'.
    Good find
    Thanks

    I did this, didn't seem to make much difference.

    Hi guys, you may try the below steps and feedback to support@tp-link.com.
    1. Upgrade the firmware to the latest one and perform a reset.
    2. Ping 8.8.8.8 in cmd on a PC and check the results. Change the DNS server manually to 8.8.8.8 or ISP DNS servers.
    3. Check whether the web management page can still be logged in when the issue happen.
    4. Whether a restart to the modem will fix the issue temporarily.

    Send these information to support@tp-link.com, together with the screenshots of Status page, error message page and Network-->Internet page, System log and the status of lights when the issue happen. Engineers will help to analyze the problem.

    Done all that.

    1. Latest firmware installed
    2. Ping to Google DNS server (8.8.8.8) successful. I had just rebooted the Router though
    3. What do you mean by the web management page? If you mean the router admin then yes I can access that.When the issue is present I get the page as shown in post #7 of this thread.
    4. A restart usually fixes it temporarily

    When I get a moment I will send it to support@tp-link.com

    So I think I found the problem last night.

    I think the auto setup wizard is not working correctly.

    I went to the Status/Advanced setting of the router.
    At the bottom checking under DSL for the DSL modulation Type I found that for my TalkTalk connection it is ADSL_G.dmt.bis
    I then went to the Network/DSL Settings/Advanced setting
    I found that it was originally set to ADSL2+. I set the DSL Modulation type to the G.dmt setting

    When it was set to ADSL2+ I had already set it to ADSL2 to try and improve my SNR values. The SNR downstream (receiving data) was between 6.1 and 6.3 which is too low which I think was causing sync issues and therefore line drop. Now that I have set the modulation type my SNR downstream is above 12 and the line has not dropped. The SNR for both upstream and downstream should be above 10. Downstream is the most important.

    I am facing the same exact problem on a archer VR2600.
    I am a telecom network engineer in a domestic ISP and I am trying to debug this .... since tp-link has no clue whatsoever.
    I cannot yet determine the cause of the problem, only that it does NOT happen to all the xDSL lines. For example it happens on VDSL2 line over ALCATEL-LUCENT dslam but not over an ADTRAN dslam.Maybe there is a problem with the spectrum/channel profiles used by some ISPs.
    Furthnermore, even in the case where the problem appears when the tp-link is acting as modem + router, it does not occur when the tp-link is set to wireless router mode connecting it through Ethernet WAN to a external VDSL2 modem.

    Can anyone facing the problem post here the type of her/his broadband line ? (i.e. ADSL2+ Annex A or VDSL2 annex A)
    I will try to collect traces from both the ALCATEL and ADTRAN dslams and upload them to their support email.
