Monterey network issue came back in 12.6

[pshufd]

I had a network issue where the machine was up for a while (days to a week) and some websites just wouldn't load. I also saw this problem in Big Sur late 2021 so whatever it was was backported to Big Sur. The problem was fixed in 12.5 so I upgraded three of my systems but it returned in 12.6. It is a seriously odd problem - and maybe it's an address resolution or translation issue. Changing browsers or restarting them doesn't work. Any program fails on some websites. The only thing that fixes it is rebooting.

I haven't seen the problem in Big Sur though. So it sounds like one of the Monterey security fixes broke this again. My primary system has to be rebooted daily now which is a major pain in the neck. I'm going to add another system to my desktop so that rebooting the one system isn't as much of a pain and hopefully less running on it means that it won't have to be rebooted as often.

I really hope that it's fixed in Ventura.

Same here. iMac 2017 with 32GB RAM. Big sur was OK, but Monterey sometime stop seeing 5Gh wifi, or cable. Full reboot require to work again. I see it happens after 10-12 hours working time.

When this occurs what happens when you run speedtest?

Cable = wired ethernet? It still sees the 2Gh network?

I haven't run speed test. I don't know that I can get to it. YouTube works fine. And some websites load up instantly. The important ones, though, don't. When this happens, I usually need to get back up and running quickly. I just added another Mac to my desktop and I will run my web browser on that Mac so maybe whatever resource is hitting a limit will take longer to do so. It won't disturb so much rebooting the system running Monterey as well.

This happens to me whether I'm on wired or WiFi.

I've seen a strange behaviour in 12.5 and 6 where there is some issue about the renew of the DHCP lease. I've appeared to have solved my issue by statically defining the address for my MAC in my router.

I suspect that my issue is maybe DNR or maybe there's a cache which runs out of space.

I've tested with ping and traceroute (or whatever the macOS equivalents are) and I can definitely get to IP addresses directly - just not through web browsers and other programs using web addresses.

I assume you checked and do not have any "content blockers" running? I run into Ad blocking extensions causing problems with some sites. Some ad blockers work more like firewall for some programs.

I use Ublock Origin on Firefox. But it's well-tested and used and I use it the same way and on the same sites on multiple operating systems and it's only a problem on Monterey.

Strange thing, if i do manually TCP setup, everything is working but outlook stop getting connection, indicate error.
Outlook version 16.65. If i switch back to DHCP, outlook working fine

I haven't run speed test. I don't know that I can get to it.

It's on the app store or you can run it via Safari.

I meant that I don't know if I can reach the website to run it.

It likely won't happen very much again as I've moved all of my web browsing off the system and onto another machine not running Monterey.

Download the app from the app store using the Apple store app on your mac.

Ran into the problem last night and played around with ping and various browsers as it wasn't during the business day. I didn't find any more diagnostic information. A reboot fixed the problem. So about 10 days between seeing the problem on the M1 mini with 16 GB.

There's a speed test command in Terminal now…"networkQuality".

networkQuality -h

    USAGE: networkQuality [-C ] [-c] [-h] [-I ] [-s] [-v]
    -C: override Configuration URL
    -c: Produce computer-readable output
    -h: Show help (this message)
    -I: Bind test to interface (e.g., en0, pdp_ip0,…)
    -s: Run tests sequentially instead of parallel upload/download
    -v: Verbose output

I usually do:

networkQuality -sv

Seems fine as it indicates that up up and down is a bit more than what I am rated for.

I suppose you could try various DNS settings on both your computers and router to see if there's any difference in webpage loading or lagging issues.

It's not a performance issue. It's a connection issue.

Some web pages load instantly. The others fail. It's always the same set that work and the same set that fails.

It's not only web browsing but other applications connecting over the network.

People use DNS for content filtering…which demonstrates that it can have an effect on what loads and what doesn't.

I'm not saying that's the answer here but as an example I was in London on someone's home wifi and couldn't get a media file to send using Whatsapp on my iPhone…although messaging was working. I changed the DNS settings on my iPhone and media started working.

I can always go back to Big Sur as I don't see the problem there. I would like to give Ventura a try when it comes out but on an external drive. One other approach would be to go back to 12.5.1 as I didn't see the problem there.

 

[BrianBaughn]

Just for information…I use Firefox as my main browser with the uBlock Origin extension in Monterey 12.6 and don't have any issues with websites not loading. This is on a Mac Studio M1 Max via ethernet to a Linksys router running DD-WRT and a Arris modem connected to Xfinity cable internet.

This Mac is less than a month old and…for some reason…I don't remember why…I set its DNS to the Google ones…but I must have noticed something odd to make that change. My router has the OpenDNS DNS servers set and previously my Mac was getting DNS via the router.

 

[pshufd]

I'll look into doing that. I think that my son does that.

 

[pshufd]

I checked my DNS settings on one of my systems showing this problem and was surprised to see that it was set to one of the Google DNS servers so I did a reset to default and now there are two for IPV4 and two for IPV6. I'll check my other systems to see if they are similar. I do not recall setting this manually though my memory isn't the best these days.

 

[pshufd]

My M1 mini had the default DNS servers so I replaced them with Google and two other companies. We'll see if that makes a difference but it may take a week or two to find out.
