I wonder if anyone could help me understand something here?

Until a couple of months ago, I had a Netgear WNDRv2 router running a Kong build of dd-wrt from about 2016 or 2017 sometime (I think. I started around 2016 and upgraded it once or twice). It just died one day and refused to switch on properly anymore, so I've bought a new Netgear R7000 and I've installed a more recent Kong build on it.

On the old router I had been using the ad-blocking code from here (the bit further down) without any other modifications and it was pretty successful. I have tried to do the same on my new router and suddenly I'm getting adverts on YouTube constantly.

My confusion is that when I tried looking this up online, all I keep coming across is discussions and posts saying that it's not possible to block the Youtube adverts because they come from the same source as the videos themselves. Some of these comments go back years.

What I don't understand is how, if this is the case, my children had barely ever seen an advert on Youtube until I had to replace the router.

Could someone enlighten me?

hmm yep first make sure this script is working
than if needs add this command before the script
sleep 10
as well add the script in start-up instead of firewall
this lines are invalid remove them as those links are broiken

"http://jansal.googlecode.com/svn/trunk/adblock/hosts" \\
"http://adblock.gjtech.net/?format=hostfile" \\

i also noticed my very short scripts ware not working and D/L those host files to block ads so its either something to prevent it or updated ash/bash script that needs ad-script revoking or changing DL locations and ect....

also it might be a due to updated DNSmasq as there are reports in svn about ad-blocking problems with it...
https://svn.dd-wrt.com/ticket/6315

p.s. in fact this script above its working with those 2 lines removed, i test it also optimised it to save some space... but even thou its not executing all the links, although they are D/L
read hosts executes not all of them but only 3 very randomly and not more than 10000 ish
host names are added, so there must be a limit or something...wrong with DNSmasq i guess i ll post you a PM with this script i tried on the last Kong build 37845
just bear in mind this script need long time to load very long time...

ops you can fairly remove this line too

"http://someonewhocares.org/hosts/zero/hosts" \\

as it not executes it at all

Thanks for the pointers. I'll try to investigate those things properly later on in the week.

To return to my other point though, is it currently possible to block adverts on Youtube? Has the situation changed at all in the last few months?

It's not possible anymore. I have a modified version of the script, which is only 10 lines and it works. But for YouTube is not possible to block ads because as you just said the ads come from for example: www.youtube.com/n4u8jgttji?source=ads... , while the video comes from: www.youtube.com/n4u8jgttji?source=vp9... (this is a silly example but i think you get the point).

So as hosts file block per domain base, and not with regular expressions like adblockers extensions, then there's no way around it.

[SisyphusBond]

And this is a recent change, right? Because I definitely still had them blocked in early September.

[Alozaros]

Xeon2k8 in your case this script you posted blocks/uses 10k ish host names, and this one i've, does 64k from a single host domain...
sadly past sept i had 200k ish almost, with another very short script ...now not working and forced to use 64k one...instead

to be honest i use a combination of adblocking stuff like win 7 hosts, ad blocker on router level and one in my browser and it works ok no ads at all

[SisyphusBond]

Oh I get no adverts on all the laptops in my house already. That is covered by various browser extensions.

It is the Smart TV that my kids now watch YouTube on that is my concern here.

need a CONTENT blocker on the device itself to get rid of ads/tracking when the content comes from the same domain as the junk/tracking.

for domain blocking, id use, and do use, dnsmasq instead, much simpler to understand, does the same thing. assuming ur router isnt affected by https://svn.dd-wrt.com/ticket/6315

Hasn't YouTube changed the way it host's ads these days with them coming from the same address as the video you are watching so makes it harder to block via a host file
