You may have to give us some examples :)

Also am I correct in understanding that you say your TV uses Getflix but everything else uses, I presume, your router as DNS.  So your ISP servers, or similar.

Are you by chance blocking some Google DNS sites with static routes? Perhaps thats causing an issue.  Or do you do any blocking at the port level? I ask because I use Pihole and only allow that to do upstream DNS queries on my network. Everything else has port 53 blocked.

removed static routing that that doesn't seem to be the issue!

[s]Yes all Google DNS are blocked by the static routing.

But it's only my new laptop that has problems, my 2 other computers are fine.

Examples are hard as it's not the whole site but only one or 2 particular pages here and there.

Oh yes I recall now my wife's phone can't access one amazon page but my old computers can.[/s]

and now it'can't open my facebook page (auto login) but on a different browser without auto login it opens facebook.com

ok lol i've removed the static routings and the laptop is still not playing ball! let me restart ...

old computers

- custom desktop unbranded asus motherboard, windows 10 pro, up to date

- 6 year old dell running windows 10 pro - not up to date because it is unable to update/stuck at updates since about a year now

new computer dell inspiron 15 7000 running latest windows 10 homw

very weird

that one website is not important, it is ea game forum login. I can access the forum but just cannot log in.

"this site can't be reached. error connection reset" ERR_CONNECTION_RESET

Wild guess, some kind of ipv6 something, somewhere, somehow ?

Sounds like a Classic MTU issue.

Have you played with any Router network settings like changing the MTU/MSS/Changed Firewalling rules to block ICMP?

I have now brought the same device to work, connected to work wifi, and the same thing!

So it's not (just) my home ISP, not my home router, but I'm guessing it's the laptop itself.

ALso note I have tried different browsers both at home and work.

I'll try to go around the settings to see if maybe I've disabled something in windows 10 perhaps. But why that one page ....

billgates:

 

Uninstall any 3rd party firewall or AV software that has come pre-installed on the laptop and then try again.

 

You are a legend.

Yes the innocent looking traffic prioritizing service called "SmartByte" is the cause of all my trouble.

Not only does everything load, they now load instantly as opposed to a big delay before things happen.

It is getting uninstalled right now.

The first thing I do when I buy from dell/lenovo etc, is to reinstall the OS --- solves all the crapware issues.
