    Hello all.

    After Virgin changed some settings on my router, it worked fine for a few days (the longest in a while) but then broke again.

    Virgin will replace my router free of charge, so that will be the next step. I will keep you posted.

    changing DNS server also requires you to clear DNS cache to prevent using old entries:

    Code:
    Clear-DnsClientCache
    To troubleshoot issue further consider resetting network in:
    Settings -> Network & Internet -> Network reset
    with 5 min to complete

    You can also log into router and adjust parameters: DNS etc..

    The issue is still present and Virgin keep fobbing me off when I call them (three times now).

    I will keep persisting.

    Apparently it has now been "passed to their IT team for monitoring and they will call back in 48 hours".

    I don't know about Virgin mobile on your side of the pond but whenever an ISP offers anything for free over here, it goes without saying, you also get another 2 year commitment on your contract.

    With the ever changing Wireless & Telecom business opportunities, I don't want to be tied to a specific ISP. My current wireless provider just bumped my speed from about 15 down / 1.5 up to 65 down / 22 up. I'd guess they're worried about the competition.

    I still don't want to start another 2 year commitment with them because Starlink is beginning beta testing in my area and should save lots of money and finally give me uncapped internet.

    So, if they do replace your router, will you have to sign-up for a longer commitment?

    No, thankfully.

    The the router has arrived and I've set it up from scratch.

    I will let you all know how it goes.

    Here's hoping this has fixed the problem.

    I am not especially surprised but a new router hasn't solved my problem.

    My PC is still occasionally losing DNS and my laptop is losing network connection during a daily backup.

    I will keep working at this.

    Next step is to go back to basics and switch off all devices apart from my router and test the backup, then just use my PC and router etc.

    otronics,

    Im following your dns trbl as I have same trbl loosing dns with a D-link 504t router/modem. I have two identical routers set up identical and both do the same. Ironically i have had this isp for many many years and never had a blip with the routers. The dropping dns started a year or so ago and i've yet to solve this other than rebooting the router. Good luck & hope you or others find something that I can use........

    Note to add: Also using Kaspersky anti-virus

    Hello.

    Interesting you have the same/similar problem.

    I've had some time tonight and gone through things and I have an update.

    I have three routers/repeaters:

    * The main Virgin Media router/modem (which has recently been replaced so this is not the issue).

    * A downstairs repeater (DHCP switched off).

    * An upstairs repeater (DHCP switched off).

    I switched off my two repeaters, ran my laptop backup several times and it worked with no network disconnection. Excellent.

    I have switched my downstairs repeater back on and all is still working.

    What I haven't done yet is switch back on my upstairs repeater. Any guesses? This is a D-Link router. How very interesting. It has been running for about four years without issue - in fact it's been very good.

    I will need several days/a week or maybe more to monitor things to see if this has cured my main problem (my PC 'losing DNS') and to see if my laptop backup continues to work as it should.

    I am certain Kaspersky anti-virus isn't the problem.

    - - - Updated - - -

    Edit: forgot I have switched off my VOIP router too (DHCP disabled again). I'm going to leave it off along with my D-Link repeater and switch these back on in stages over the coming days/weeks.

    My laptop backup problem is definitely solved - well, the cause found. That was my D-Link router playing up.

    My PC was working for days and yesterday lost DNS again.

    I've switched off my other repeater router to see if that makes any difference. I doubt it will.
