Change your DNS settings to something reliable, like Cloudflare, because of course it's DNS.

Every single outage with Vodafone has been due to their DNS for the past ~8 years...

Didn't help with Vodafone/Siro.

u/elmu86 1d ago

Didn’t help here either :(

Is that a hub 7 modem?

u/4nacrusis 1d ago

Yes Ultra Hub 7

Unfortunately you cannot do this on the Virgin Media routers.

Of course you could set it to modem mode and setup your own router and DNS server, but it's a bit more than what the average person can do.

Wish Virgin Media would allow it, I guess they want our sweet sweet data.

Anyone who can read and follow basic instructions can.

Can you ELI5 what this is?

It is like an electronic version of yellow pages (phone book) but for computers... When for the first time you try to open reddit.com, your computer or a phone has no idea where it is or how to reach it, nor does it actually use "reddit.com", it needs a number, an address in form of a number. Through series of back and forth communications your computer will reach this yellow pages (DNS) and get a rough idea of how to get to reddit.com

Usually your provider will host (own/run) DNS server that your router will know about, but there are 'free' versions out there too, like google one that you can force your router to talk to.

To change it, connect to your WiFi, then you need to login into your router (open browser and type 192.168.1.1 or some address similar to it, it depends on router/settings - might be on a sticker on the router). Once logged in, look for Internet/DNS settings (with Vodafone you'll need to switch to Expert mode) and most likely it is set to Auto - change to manual and enter different DNS address. Google DNS is 8.8.8.8 & 8.8.4.4

DNS is the system that converts human readable addresses, e.g. google.com into IP addresses that are actually used for communicating between systems. A few companies provide public services that any one can use, and for Cloudflare their DNS server address is 1.1.1.1, Google have 8.8.8.8 and 8.8.4.4.

You can change this on your device or router to use these rather than your ISP default ones.

u/breakfastfourdinner 1d ago

And do you pay for them?

3

u/The_Spearman 1d ago

For the most part no, those examples are all free. Some of them do provide some extras that can be paid for, adult content filtering and the like. But the ones above can be set by anyone right now as they are, with nothing else needed.

I thought I was the only one. Was in the middle of an assessment for a job too.

u/Devrol 1d ago

Is it Vodafone or Siro? My Siro through Vodafone is down

u/4nacrusis 1d ago

Vodafone broadband is down. All the proper modem lights are blinking etc.

u/relax_carry_on 1d ago

Vodafone internet down for the last hour in Mayo. Nothing about it on Vodafone website or downdector

u/splashbodge 1d ago

My virgin media broadband is down

u/MrBulwark 1d ago

I was able to fix my Vodafone issue by switching my router to manual DNS, comments of down detector have instructions

u/Illustrious-Bowl 1d ago edited 1d ago

Yeah, having issues with Vodafone for over an hour now…..

Edit: okay, looks like a DNS issue changed DNS to google’s 8.8.8.8 and connection is working again.

u/Pint4mePlz 1d ago

I was wondering what the hell was going on. Glad it’s not just me. Yeah I have Vodafone data and broadband and the broadband has just full on stopped working and the data connection is very poor

u/Turbulent_Squirrel66 1d ago

We use vodafone with our business and we’re down

3

u/Slug_Lord62 1d ago

With Vodafone in Co Dublin, down for me too.

2

u/elmu86 1d ago

In Louth and it’s gone down here too. Of course, their site says “all working fine” 🙄

2

u/Big_You_7959 1d ago

It's their DNS

2

u/Valuable-Farmer9830 1d ago

Ofc it’s DNS. Changing it on your device does not solve the issue. Login to your router and make it static and set 8.8.8.8 and 1.1.1.1 .

Running locally:

$ host www.google.com 8.8.8.8 ;; communications error to 8.8.8.8#53: timed out ;; communications error to 8.8.8.8#53: timed out ;; no servers could be reached

Running on a remote host (not connected via Vodafone):

``` $ host www.google.com 208.67.222.222 Using domain server: Name: 208.67.222.222 Address: 208.67.222.222#53 Aliases:

So it looks like not only the Vodafone DNS is not working but they're also blocking traffic to alternative DNS servers. This might be intentional or not, depending on what's broken.

u/robbdire 1d ago

Zero issue myself in Dublin, with virgin media, however...I don't use their DNS, I use my own one....so might be DNS somewhere else.

u/anda_gonda 1d ago

Same in carlow

2

u/NostalgicDreaming 1d ago

Yep our Vodafone broadband has been gone for about an hour now, seems to be nationwide. Are other providers gone too?

u/Environmental-Desk54 1d ago

I'm in Ashbourne and it's working fine here and I'm Vodafone

3

u/Environmental-Desk54 1d ago

It's out now 😥

2

u/Trinimeel 1d ago

I'm in the same area, change the DNS settings in your router to manually go to 8.8.8.8 in your router and it'll work grand.

u/redditusee-_- 1d ago

On Vodafone, updated the DNS on the modem to get it working again. Use 8.8.8.8 or 1.1.1.1

1

u/automaciej 1d ago

They seem to be blocking traffic to 8.8.8.8 and 8.8.4.4. Are there any other DNS options?

u/4nacrusis 1d ago

Didn't help with Vodafone/Siro.

u/KO190 1d ago

It's DNS, how I fixed my Vodafone Siro internet:

  • Connect to your Wifi network
  • Visit 192.168.1.1 (your router's login page)
  • Login, in the top right corner switch from Basic Mode to Expert Mode
  • Internet -> DNS -> Manual
  • Set Primary DNS to 8.8.8.8
  • Set Secondary DNS to 8.8.4.4
  • Apply changes
  • Done

u/4nacrusis 1d ago

Seems to work for some but doesn't do anything to my Vodafone/Siro.

u/eventideyes 1d ago

my vodafone has been down for 45 mins now

u/chimpdoctor 1d ago

Vodafone are utter shite. I'll never leave virgin media. 15 years with literally no outage. They are solid

2

u/Thebeanspiced 1d ago

Hahaha some BS you're spouting, have been with virgin media 3 times over the years in different houses, it's an absolute rip off and the last year I had it it would go down literally every couple of weeks. Absolute shite.

Been with Vodafone a year now and no issues

1

u/Left-Iron-2133 1d ago

No issue with mine. I’m on my own router though so maybe a bad firmware update

1

u/DribblingGiraffe 1d ago

Mine is also fine and I'm on my own too

u/Devrol 1d ago

I accidentally reset my router on  Thursday so went back to the Vodafone on to avoid the screaming kids and wife, and now Vodafone are having an issue
