    Cudy Switches; do they pass VLAN tags like tp-link do ?

    I think the conventional wisdom on that is "it depends". The manufacturers don't specify this behavior, so it might or might not do what you want. I wouldn't assume it's consistent across all switches from the same manufacturer. It's possible that it might even vary from one batch to the next...

    Replacing Asus XT8 setup

    Makes sense. We tend to look down our noses at wireless backhaul around here, because its performance is worse than wired backhaul, but it can certainly be better than nothing. A well-placed third XT8 might alleviate your coverage problems quite a bit. (Wireless backhaul between two XT8s can...

    Using Ubiquiti Airmax Omni 5G (AMO-5G) antennas with currently available APs?

    While we're on the subject ... I can't believe that 6GHz-band support matters for what you want to do, but there might still be reasons to shell out for the U7 Pro Outdoor instead of the non-Pro model. See this current thread on the UI forum for some relevant discussion.

    Replacing Asus XT8 setup

    If you don't have adequate coverage now, it's very unlikely that replacing the two XT8s with two other devices will fix it. Wifi range is largely limited by the laws of physics and the legal restrictions on transmit power. A plan that's much more likely to succeed is to get another AP...

    Using Ubiquiti Airmax Omni 5G (AMO-5G) antennas with currently available APs?

    Ah. So I'm betting that the main thing to pay attention to in those specs is "Maximum TX Power: 27 dBm". The Swiss Army Knife AP (UK-Ultra) looks pretty sad by comparison at max 20 dBm. So even assuming that the UK-Ultra works with your sector antennas, it will be 7dB lower power and hence...

    Using Ubiquiti Airmax Omni 5G (AMO-5G) antennas with currently available APs?

    Are those existing APs really UniFi, or are they from the UISP (Airmax) product line? AFAIK, the UniFi line doesn't really intend to replace every use-case that UISP supports, which is why Ubiquiti is still selling UISP products. You might need to buy some newer UISP APs instead of converting...

    Why are AP transmit powers higher than device transmit powers? What is the design intent?

    I did a little more research on my recollection that there might be regulatory limits, and confirmed that for the 6GHz band: clients are restricted to Tx power at most 6dB less than the AP they are connected to. You can find that in official FCC documents here or here. I did not find anything...

    Why are AP transmit powers higher than device transmit powers? What is the design intent?

    Right. I made the same point in different words today over in the Ubiquiti forums: if you've only got one AP, you might as well set it on max Tx power. The clients might be able to reach it or not, but they have no alternative, and reducing the Tx power won't improve anything. But as soon as...

    Why are AP transmit powers higher than device transmit powers? What is the design intent?

    APs generally have better antennas than clients, simply because there's more space for an antenna. So that allows them to "hear" the clients better, and that allows for a difference in Tx power without changing available throughput. Beyond that, I think there may be regulatory requirements...

    Struggling with "default" VLAN on D-Link DGS-1100-24V2

    Hmm, I'm quite befuddled by the terminology being used here. As far as I've ever heard, "native VLAN" and "untagged VLAN" mean the same thing, namely the VLAN ID that's deemed to be associated with packets on that port that don't have any VLAN ID in their headers. (wikipedia, for instance...

    Is Unifi worth the upgrade?

    You'd think an ethernet cable would be a fairly foolproof bit of kit, but I've had them fail too...

    Is Unifi worth the upgrade?

    Yeah, you can use a non-UniFi switch if you wish. The only expected consequences of that are that you can't use the UniFi controller to manage the switch (e.g. to set up VLANs on it) and the controller will probably not have a good idea of the network topology. I really doubt that your...

    Best way to protect from lightning strikes?

    Yeah, I've lost equipment to nearby lightning strikes too. For a point-blank strike, that's something that only insurance will help with. But as several upthread responses hinted at, you should hire a well-qualified electrician to look over the grounding connections and surge suppressors in...

    Is Unifi worth the upgrade?

    SFP-to-RJ45 modules are essentially full-on ethernet switches crammed into an unreasonably small amount of space with typically a very poor heat-dissipation situation, since the SFP cage standard is meant for fiber-optic modules that have very low power requirements. In consequence, they will...
