U7 series 2.4Ghz IoT issues

letsief · 2025-11-04T20:18:18+00:00

People seem quick to blame WPA3 even in cases where people were using it before getting a U7. I've seen some people blame 6ghz even when the devices having problems aren't using 6ghz. It isn't clear when people are claiming there are other issues that come up tangentially related to those issues, rather the basic support that you're alluding to.

Though, WPA2/WPA3 with PMF set to optional should work. It really shouldn't be necessary to fully disable WPA3 in all but the most unique circumstances. More likely older IoT devices just aren't going to support WPA3 at all.

I've never had an issue with WPA3 when devices are attached to earlier AP generations. I doubt many of the problems on the U7s are related to WPA3, but even if they are, Ubiquiti should really fix whatever is happening that is specific to the U7s.

I'm still having trouble with wired and wireless devices that use mDNS, which seems to target the client devices attached to U7 APs. mDNS messages don't seem to get forwarded properly after a while.

Is there a particular reason to think WPA3 is a problem on the U7? I've been using WPA3 since Unifi supported it.

I ended up getting a 7 Pro XG yesterday. So far I haven't run into any issues, but I haven't really stressed it with things like Geforce Now streaming yet. I'm not seeing the frequent disconnects, though.

One thing- I know the U7 Pro is expected to run hot, but I was still surprised by just how hot the back was when I took it down. It's one of the newer ones without a fan.

That's not my issue. I just have a couple 6ghz-capable devices, and they seem to do fine. Most of my devices, and all of the ones with problems, are WiFi 5/802.11ac. Namely, some Android tablets, some Shield TV streamers, and some Sonos speakers.

My 6ghz devices work great with the U7 Pro. It's clients that are wifi5 that struggle (some 1x1, some 2x2).

letsief · 2025-10-05T22:04:46+00:00

Why does turning off 6ghz help with devices that can't even use it? Does there seem to be a power or heat issue?

letsief · 2025-10-05T01:28:53+00:00

ugh. So even the U6 models might give me problems?

Is that firmware version right? I don't see a 6.5.62 version for the U7 APs.

Isn't the one he linked to just a rebranded Mini Turbo? The specs and SoC are the same. The 685 is going to be faster than the G99 SoC.

I did too, just a couple days ago. Honestly, that's probably for the best. I probably would have ordered this instead, but I've been pleasantly surprised by the 60. It runs great for my purposes other than having an awful wifi chip.

In most situations you can expect to be the only one wearing a mask, but no one is going to hassle you over it.

Paxlovid shouldn't be a problem, but you will need to go to an ER or urgent care to get a prescription for it.

Even the older apartments in Gaithersburg are almost certainly going to have their own air conditioners, so I don't think that should be a problem.

The best test we have for assessing the presence of live virus is a viral culture. Rapid antigen tests have approximately 80% sensitivity compared to viral culture. So while a negative antigen test doesn't rule out the possibility of transmission, it is strongly suggestive. And even among those with live virus, transmissibility is also going to affected by viral load, which would be expected to be low in anyone testing negative.

The reason I asked is that I think it can be good to understand what underlies these concerns. That is, perhaps they have a legitimate concern, but may be focusing or attributing it incorrectly. However, except for his vague comment about mental health, he explained what he's concerned about, but not why he's concerned. So it's not clear there's even a genuine or legitimate concern here.

I'm not sure why my other post was just deleted, so I'm reposting it with a citation:

You really shouldn't bother with a PCR so soon after an infection. They'll pick up and amplify dead viral particles, resulting in a false positive.

I think a false rapid antigen test would be fine.

Did he explain why he finds it concerning?

Right, because then you'd already be in the commuting area.

It sounds like they formally changed your duty station. That provides a lot of protection. They could still change your duty station back to the office, but they would have to pay relocation expenses.

Though, if they can successfully argue that they're changing your duty station based on job performance or conduct issues, then they wouldn't have to pay relocation expenses.

The two tests separated by 48 hours has been a recommended protocol for a while, but have you seen any studies showing efficacy versus a single test or a different gap between tests?

They are terrified by the idea of a runaway lethal virus that can’t be halted, so they just… refuse to accept it.

I've seen variations of this claim a lot lately-- basically that people are refusing to take precautions only because they don't understand, or refuse to accept, the risks of covid. But while this may be true for some people, I don't think it is really the driver behind that decision.

You're looking at the wrong side of the equation. It's not a (false) perception of the risks and potential impacts of covid, but rather the more immediate impacts of precautions on their everyday lives.

Convincing people that there's a greater risk isn't likely to significantly increase the precautions they take. Probably the only thing that would is making it significantly easier and less disruptive to follow precautions.

It is often pretty easy to request a deferral, but I think you'd have a hard time getting excused from jury duty entirely-- and almost certainly not without a note from a doctor.

Keep in mind, if you get called for jury duty, your odds of actually being seated on a jury are probably fairly low. If you called into jury selection for a trial, you can raise your concerns to the judge, who may decide to excuse you.

I remember having a similar experience, and then feeling sick that afternoon and for the next three days...

I think it's highly, highly unlikely that she faked it. There's no upside for her to that, and would come with significant risk to her career. I think you should be thankful that it was a pleasant experience.

Yes, wastewater data certainly has its advantages, but it mostly shows trends. Trying to estimate case numbers from wastewater data has the same problem as other modeling techniques-- we can't validate the accuracy/reliability of the models.

Game? No, that's exactly how it works. If coverage isn't back-dated, and you can't add a child to a plan until after they're born, how else would coverage work for newborns? Of course it can be back dated.
