For a few weeks, I've been finding that some sites aren't loading for me via my Orcon connection. Examples:

https://www.wikipedia.org/
http://www.engadget.com/

Do these fail for any other Orcon users?

I ask because I'm unable to access these sites via either my PC (Windows 10. Ethernet connection) or my cellphone (Android. Wifi on the same network). However when I flip over to mobile data on the phone, I can access the sites just fine.

Other sites (both https and http) all work fine. It's the same ones that reliably fail.

Chrome's error response is (failed) net::ERR_TIMED_OUT (timeline shows that it makes a 30 sec attempt with zero response, before returning this error message).

Before I contact Orcon, I wanted to check in with you guys, to see if you can think of any troubleshooting I should be doing. Maybe it's something I've done? I can't really figure out what would cause selective site access issues across 2 devices like this.

Here's what I've covered so far:

-- Tested in Chrome, FF, IE10 + Edge, Opera.
-- Nothing blocked in my hosts file.
-- I can ping wikipedia.org fine (188ms avg).
-- I can tracert wikipedia.org (final hop is to ipv6 address 2620:0:863:ed1a::1, which fails if I try to visit https://[2620:0:863:ed1a::1] directly via the browser.
-- I have had my Orcon modem powered off for a couple of hours, a couple of different times (in the hopes of being allocated to a different pool/connection).
-- I just noticed via ipconfig that I currently have an IPv6 IP address, which I think is new for me. Could there be an issue with the way some sites interact with this? I wouldn't imagine so, especially not for Wikipedia.
-- I have the shiny black Orcon Genius modem (on ADSL), which I don't think I can modify or update. So I haven't taken any action there.
-- I did have some vpn software that I used super rarely for logging into work, but I've uninstalled it to try and be 100% sure that Orcon is handling my traffic directly.
-- Have run a Malwarebytes scan, as well as a stock Windows Defender scan.

Big thanks in advance if you have any suggestions. :)

Have you tried using third-party DNS servers? I certainly don't suggest this as a permanent fix, but it's a relatively simple way to narrow down the problem.

No luck with the alternate DNS server sadly. I really felt like that was going to be the silver bullet.

I used Google's service:
8.8.8.8
8.8.8.4
2001:4860:4860::8888
2001:4860:4860::8844

First I tried via Orcons router interface (Advanced Settings -> 2. DNS/UPNP/DDNS) and rebooted the router. No change.

Then I updated Windows 10 via the networking properties, with the same IP addresses. Via cmd I ran ipconfig / flushdns. Still doesn't work though.

I've reverted back to ISP settings for now.

 Hmmm both those addresses work fine for me using Opera 35 stable 

 

 

 

can you take a look at the Advanced Setup / LAN and check the DNS address your router is using if it's anything other than 121.98.0.1 and 121.98.0.2 then change them to these

I have a section under Advanced Setting called "6. Local area network settings", but there's no place for DNS info there.

As above though, I do have a section "2. DNS/UPNP/DDNS", and changing up my dns servers there to the google ones, made no difference. Default is "Let my ISP manage the DNS server:"

I dropped the IPv4 Orcon DNS addresses that you suggested in there to try as well though, and it makes no difference (I first did a DNS flush from Windows cmd, and rebooted the router).

...and now I have a cricket that's gotten inside my house and is currently going mental with the cat in hot pursuit.

Pretty sure that these are the signs of the apocolypse. Pestilence, No internet, ... (well, 'no internet' just by itself is really all we need for a modern apocolypse).

Does anyone know a good gypsy or witch doctor?

I had problems a few weeks ago using DNS 8.8.8.8 i switched back to Orcon's DNS and that appeared to fix it.

Thanks everyone for your suggestions. You got me on the right path.

Final resolution was to do a factory reset on the router. I guess it must store some dns addresses there as well. Now that I've re-set, I can access those sites no problem.
