WIfi has no valid IP configuration

Hi everyone,

I've been without internet on my PC since Thursday. I've tried flushing the DNS, setting a manual DNS, renewing the IP and Winsock. I've even tried reinstalling the operating system, drivers and bios. My PC will connect to the network both wireless and wired but it won't connect to the internet. Everytime I do IP renew it says that it found an IP that is already in use. However my pool size goes up to 200. I'm really not sure what's causing this.

  • I had a look through the Mac address for the intel adapter and its always the same adress and random hardware addresses is turned off already. In the interest of testing things though I bought a TP link wireless adapter. Could it be worth changing the lease time to 30 minutes to cause leases to expire and then using the new network card to see it can assign an IP without munching through them?

  • You have given me some food for thought. The Pixel 7 is using random hardware addresses by default. However for some reason the lease time on the phone is only set to 1 hour. Could this be what is causing the issue maybe?

    I don't get why they have a hitron router business account by the landlord

    I think they its unfair for someone not to setup their own broadband under their name sure I get why this might be done say you rent but you leave with the contact still going where by the landlord can have it under their name if people move in or out but what if the person stops using the VM internet and uses 4G/5G and does not pay the landlord VM installed internet which is fair unless stated in rent you will pay for the landlord VM installed internet and then what if it goes wrong like we have here which would be a simple fix change RG function in Hitron to disable for modem mode just reset the Hitron and use the default log in

    The default username is cusadmin, and the default password is password or admin admin

  • Short version - turn off al WIFI repeaters around if you have any.

    Long version - not sure if that will help, but I've got the exact same problem, even the settings are same as other mentioned before in this post. I've noticed that the internet worked just fine on a WIFI extension (hub internet has no WIFIand "doesn't have a valid ip configuration", yet it works on the extension), so I tried setting up my own extension (in repeater mode, if it matters to anyone), and noticed the previous extension connection disappeared too. Eventually I've turned off the extensions and everything works fine directly from the hub.

  • This is the issue I've been facing for a month or so now, I was on a hub3 then upgraded to the 1GB so now on the Hub 5, same issues.

    Wifi and hardwired connections keep dropping manually, when I check the ip's of the status its "Unidentified network", then when you check the ip config its always duplicate and fails to connect.

    Really struggling here as if its not the wifi its the hardwired or both, even restarting the router doesnt cure some of the devices connecting.

    This morning my laptop (work) wont connect so in a few mins ill be calling VM as this needs to be sorted, any advice here would be appreciated as I don't have much faith in VM support these days, long gone are the good Blueyonder days.

  • To update this post as I feel its necessary.

    So yesterday after the VM technician came to my house, after explaining in great details what has been happening which seemed to be a lack of valid ip being assigned to each device connected to my Hub 5 and having unidentified network or duplicate ip showing.


    My self diagnosis was a failure of the DHCP on the router in some sorts. anyway, he changed the router and all was fine, then just now a little over 24 hours which ironically is the leave time set by the hub5 dhcp devices started to get the same issue.
    Out of interest instead of resetting the router (again) I decided to just change the lease time by 1 second, pressed apply and everything was fine once more, correctly allocated ip's were assigned to every device (I have a combination of hardwire and wifi).

    This tells me there is a 100% issue with these Hub5's and after reading more in this community and on the web in general this has been happening for a long time, I didn't want to have to resort to modem mode but I will however this still doesn't solve the issue for me and many others.
    @VirginMedia, can you not update your firmware? to correct these issues or any other technical fix for this,, I'm not sure how this can get escalated any further but this needs to be done.

    Soon as this has the same issue again I'll respond to this post, I updated my lease time to 7 days which is the limit and not the default 1 day. so I'm guessing this time next week I'll be making a post.

    Your support teams on the phones are shocking and the vm technician who attending my home also agreed and apologized but this doesn't solve the problem.

    Happy to hear anymore tips on this.
    Thanks

      Hi TedsMob2014 

      Thank you for taking the time to let us know what has happened at your side since the engineer visit and what you've noticed at your side. 

      We can certainly raise this through to the team at our side to investigate further and if needed, release a fix within a firmware update. Did the engineer advise that they would also raise this at their side to be investigated?

       

  • No, I think everything I told him went straight over his head to be honest. Still getting these issues, only recently upgraded my contract as I went for the 1GB and got a discount but soon as its over I'll be off to CityFibre after 25+ plus with you guys since Blueyonder 1st started.

    So unless this gets fixed which isnt a singular issue for just me, the time has come to give up.

      Sorry to hear this is still ongoing for you TedsMob2014 

      We haven't been able to locate you on the systems at our side.

      Can you advise which devices this is affecting and if you've any 3rd party set ups or made any changes to our routers default settings at all?

  • I’m having the very same problem for the second time after having my Hub 5 replaced just 4 months ago after months of not being listened to by Virgin. 

    My home security and heating devices still function fine on the main WiFi network, but a variety of Windows, Android and Apple devices do not - they connect but have no internet and generate “no valid ip configuration’ errors. The same thing happens with both WiFi and Ethernet connections, but the same devices work fine on the guest network. 

    @VirginMedia why have you still not fixed this issue with your Hub?

    @John_GS and @Carley_S can either of you help?

      Perhaps not quite the same.

      You have a domestic VM Hub 5, where as the OP in this thread had a business connection with Hitron Router, their config error was use of 149.122.122.122 as a DNS.

      Best to create your own new thread to avoid your question & discussions being lost.

    192.168.0.1  works as a DNS on a VM Hub 5, a Hitron could be the same.
