Fast speed, slow loading, broken websites

[X-Morgan]

Hi all, looking for help and advice.

Two weeks ago I noticed that my connection wasn't as stable. You kinda get used to how quickly pages load and notice anything out of the ordinary.

The biggest culprit was any speedtest results showing 200-220Mb, but pages like BBC News, Twitter, YouTube showing blank white pages and "establishing a secure connection" in Chrome. Once it was done it half-loaded a site with broken links as images.

It affected anything connected to the network (ethernet or Wi-Fi).

I assumed it would just resolve itself, but it didn't.

I would also get a lot of DNS style errors and "page failed to load" within Chrome or failed logins for anything using https. But if you left it on the error page, after about 60 seconds, it would load perfectly.

I've been backwards and forwards with tech support, however it's been no use as they just tried to sell me Wi-Fi Booster pods for some reason, or blame the fact that I'm running in modem mode (even though I told them that the issues persist even in router mode).

Yesterday I had an engineer out and he replaced my Superhub 2ac with a Superhub 3 and he said he went out to the signal box and tightened a few connections while he was there.

Power levels and other readings he said were now fine with the Hub 3 installed, but as the day went on, the issues were still there.

2 hours on Tech support yesterday and today have got me no closer other than being told "your connection is being monitored and will improve within 24 hours" but I've been told that about 6 times now over the last 2 weeks.

I checked these forums and noticed people having very similar issues (PSN, DNS, slow loading).

Any and all help is appreciated.

(Also, for info, I changed my DNS and the issue was still there)

If you need any details, please let me know.

Do a pinhole reset for a good 30 seconds.

Can you post some stats.
Go to 192.168.0.1, do not log in, click on the link "Check Router Status".
Copy and paste the Downstream, Upstream and Network Logs as text (not images). Mask any public IP address.

[X-Morgan]

Done the pinhole test twice now today when on call with Tech support and still having issues.

Ironically, just tried to reply and got a ERR_NAME_NOT_RESOLVED on Chrome. This was even after I flushed the DNS cache this morning.

Apart from possible noise on one of the upstream channels I'm not seeing much wrong. Can you try a different browser?

[X-Morgan]

It's not the browser that's the issue, it's just a symptom of an unknown larger issue which affects anything that's connected, be it WiFi or ethernet.

Just tried Twitter there on my phone and when it's on WiFi, it'll take 40-60 seconds to refresh the feed, and it refreshes instantly when it's on 4G/5G.

**Update - Error messages would flash up over the last two weeks that I couldn't see since they changed so fast, but I saw a DNS_PROBE_FINISHED_NXDOMAIN just 2 minutes ago**

[legacy1]

change DNS to 194.168.4.123, 194.168.8.123 or 1.1.1.1, 8.8.8.8, 9.9.9.9

[X-Morgan]

I've went through Virgin, Google and Cloudflare's DNS the past 2 weeks and still the same. Which surprised me.

[X-Morgan]

Still getting these errors and nothing requiring a login will load properly.

Getting lots of 'DNS PROBE FINISHED NXDOMAIN' errors, only for the page to load up 30 seconds later and pages half loading with broken thumbnails where images should be.

Superhub is still on router mode as tech support over the phone says it allows them to run tests, but I'm not holding my breath.

The browser error messages are symptoms currently affecting all chronium based browsers, Chrome being the main culprit. It's especially bad on the VM website.

I had a multitide of those errors on my previous PC which was sometimes fixed by clearing browsing data or using an incognito window.

I had also uninstalled and reinstalled the browsers however the issues kept reappearing. 

I've had no issues whatsover on the AIO PC that bought a couple of months leading to me to believe that the browser data was corrupt.
