So, this AP is significantly bigger. It has 4 radios 1 = 2.4g, 1 = 5g (36-48), 1 = 5g (149-161), 1 = 6g. That is nice, but wish they would support UNII-2 and UNII-2e. It is pretty easy to setup in Omada, I just plugged it in and it adopted just like all other AP's. One thing I am finding quite irritating - the AP will not power the upper 5ghz radio nor 6ghz if it does not have full power (documented, it needs 60w aka POE++ or UPOE). So, the trouble is I have it powered with the power adapter included (wall wart), and the switch I am plugging into is a 802.3af Poe (not poe+). That means all radios are down (maybe 2g is up) but the device is just manageable with that power level. BUT....here is the issue. When you plug in the power again without a reboot, you need reboot the AP in order for the upper channel radios to comeback. Here is the scenario, if I unplug the power (wall) the PoE will keep the device reachable, but all radios are down (maybe 2g is up). In order to bring back 6Ghz, I must reboot the AP. In addition to being a giant annoyance, there isn't much notification that the radio isn't up (I noticed because it's in my house). So, if these were remote, and lost the power but had a lesser back up power connection (like default poe, or poe+), then their isn't much notice that your higher radios are down. I did get one message, but the other times I only knew because my phones were not connected at 6Ghz, and then discovered it was not broadcasting. Reboot? Problem solved. For now (until I get a full PoE++ switch or Injector) I've just disabled the PoE port so it give no power for that port. But that's a poor solution. The point of this rant is it should be more intelligent about bringing the radio back online if there is juice (power). If there was a reduced power incident (one to wall, one to poe or poe+), the radio should return after they have full power back without a reboot, I can only imagine power outages being an addition issue here if there is backup power (like PoE, or PoE+). I know, it's a bit of a niche situation, but still should be more properly dealt with. One more items of (I guess a plus?) interest. The power level is much higher (up to 28 dBm) than my EAP 245v3 AP's (tops out at 23dBm | fyi, every 3 dBm doubles your mW power in both negative and positive direction). So, to go from 23 to 28 would almost double twice the power levels. Meaning, the range is significantly higher, but I need to test with my ekahau sidekick before I have the numbers. Overall glad to get one and start getting used to it, but really angry that Microsoft is limiting the 6Ghz radio to try to force us to adopt Win11 - which is not really ready for prime time (I know some like it, but it's poorly made, so....Not having it...give us control features back, then we'll talk). For some devices, there is a potential work around, if you can use a Intel card (must be a 210 model), then must use a specific driver version and not update it. However, that is Windows discussion, not the TP-Link 690e HD. I don't care for the double 5GHz radios, if you are going to do that (for an enterprise/business device) then at least make both radios run both spectrums not one on UNII-1 (36-48) and one on UNII-3 (149-161)....and (again) it drives me SUPER CRAZY that TP-LINK WILL NOT ADD UNII-2 and UNII-2e in the US. WHY? WHY? WHY? (fyi, it appears Omada has the back off algorithm for DFS channels, aka UNII-2, so, they have the structure there....) WHY? WHY? WHY? WHY WON'T TP LINK USE UNII-2 and UNII-2e ????????? (Seriously, this isn't a new technology, or standard, and it HAS BEEN REDIFIED AT THIS POINT IN THE US!!!!!) This is a 3 star device rating at this point 1) because TP link refuses to use UNII-2 and UNII2e. At this price point it's EASY to get devices that do support those channels. Someone missed their mark in TP-Link's HQ. Also, a few other annoyances make this a really expensive version that has much better competitors (and I love the Omada/TP-Link setup, so that's hard to say). Lastly, mostly just to be pissy, I cannot find much discusison about the spacial streams (2x2, 3x3, or 4x4) so...this makes me wonder if it's not the lower of the 3. Because of these three things, OHH...and the annoying dual power thing, I'm giving this a 3 star rating (even though I've waited for these for like 2 year now). The sad thing about UNII-2 and UNII-2e is the radios that exist in nearly every 5GHz device are almost guarenteed to support UNII-2 AND UNII-2e right out of the box. It would be more expensive to find radios that didn't support it than ones that do. So, TP-Link is just being stubborn and intentionally blocking them due to a incorrectly perceived regulatory issue. But at this price point? two 5GHz channels (non overlapping) is simply not sufficient for the enterprise/business class. We need all of them. Again, someone at TP-Link HQ missed their mark. Anyway - price wise? probably very on the spendy side, I can purchase a ...
