Yes, go through the update WiFi in app, connect your phone/tablet directly to Dot. When it gives you the choice of which network to connect to, if your 5G is not showing click refresh list.
Thanks, I did that just good to know others are experiencing it so maybe it’s not my router at fault. I have an Asus rt-ac88u and its has a “smart connect” feature that is supposed to bump things that don’t need as much speed down to the 2.4ghz network but I have it turned off.
People on the Amazon forums are reporting an issue where if the dot is connected to a Bluetooth speaker, and the Bluetooth speaker goes to sleep, then the dot doesn’t work anymore. This is going to be a big problem in Europe, where energy conservation laws require that Bluetooth speakers have a minimum “one hour inactivity triggers sleep” protocol.
I connected the dot to a bluetooth speaker (bts) with an aux port and placed it on top of the kitchen cabinets. The bts has a feature to go into ‘Ready-mode’ after 1 hour of not sensing any signal from the bluetooth or aux sources. So, without a setting on the dot to ping the aux signal at a scheduled interval, I’m done. I now have to stand on a stool and touch the power button on the bts to hear the dot. Btw, this auto-sleep feature is required by certain EU laws to conserve energy, so, the bts manufacturers have no workaround to turn the auto-sleeping feature off. The dot should have had a setting to deal with this.
Also, Amazon support has verified that once you connect the dot via line out to an external speaker, all announcements come through the external speaker, which means if you turn off the external speaker you won’t hear anything from the dot. This is an issue with some people have connected them to home theater set ups which Power down when not in use.
That second point is interesting. I get notifications fine when my BT speaker is off. I have a light speaker in my bathroom, and the Dot is connected to that. When the light automatically comes on, the Dot will connect, beep, and continue what it was doing output wise, then when the light shuts off, there’s a few second delay and it starts outputting from the internal speaker.
Now if you have the Dot connected via 3.5mm, then that applies, as there is a physical circuit disconnect in the Dot that disables the internal speaker when a 3.5mm plug is inserted. Most likely as an impedance safety measure.
I’m thinking maybe you meant a wired external speaker for that comment?
Yes, thanks, I’ve updated my post to clarify. 
I guess I’ll see about the bt speaker shutting off situation. I just connected my one dot to a bt speaker I’m listening to while working outside. This same dot is wired via the 3.5mm jack to my receiver. This bt speaker powers off when nothing goes thru it after awhile. When that happens I’ll turn on the activity that connects it to my receiver and see what happens. I’m assuming the dot still “thinks” it’s connected to a bt speaker so that’s why there’s no output.
All, just a couple observations I’d thought I’d share…
I have 1 Echo and 6 new Echo Dots.
I setup my dots on my normal wifi network. My wifi network supports both 2.4ghz and 5ghz bands.
I use several of the Ubiquiti UAP AC PRO access points. I have band steering turned on which pushes devices capable of using the 5ghz band to the 5ghz band. This feature works perfect for my iPhone, tablest (iOS and Android), rokus, Macbooks. My 2.4ghz and 5ghz networks have the same name as band steering takes care of pushing them to the correct band (based on performance).
When I setup my dots, they all joined as 2.4ghz. After a couple attempts to get them on 5ghz I gave up can created a new 5ghz ssid just for devices I wanted to force to 5ghz and the same mfor 2.4ghz. This is important to me as I have over 70 wireless devices and my 2.4ghz band is getting crowded.
Once I connected them to the 5ghz network, everything was fine, except for a day later they were all back on the old SSID. After doing some research, the only way to remove the old SSID from the echo dot is to contact support, which I have not done yet. 
If I can get 6 devices off of my 2.4ghz band, I will. As a side note, my 1 year old Echo has been on the 5ghz network without being forced since I bought it (yea, I can’t guarantee it never switched over).
I don’t check in on my routers list that often but every time I have the echo has been in the 5ghz. I don’t have what Asus calls smart connect turned on (steering ) but my one dot just wants to be on the 2.4ghz so I guess I’ll leave it there.
Go to your Amazon Account page. Under Manage your Content and Devices, then Saved Wi-Fi Passwords, hit delete. Then deregister your device, and re-add it. That should force a reset of all memorized SSID’s.
This is completely unusable to me. I have three hubs, it only supports one! So I’d need a mix of ST virtual switches like I have now, shared to Alexa, as well as this skill setup for just one of the hubs. That’s a major PIA once you deviate from “standards.”
I hope they add support for multiple hubs soon. I’ll probably try it on the living room one, since it’s the only one we (rarely) watch cable on and might want to change channels.
Also they don’t support volume or play/pause yet.
This is typical Logitech work, half a**'d!

RE: wifi passwords…
Thanks, I try this when I get home from work.
Went to Best Buy today and seen the 2nd gen dot on the shelf.
Has anyone had the issue with their dot disconnecting from their bluetooth speaker and then reconnecting? After mine made the VERY loud bluetooth connecting noise at 2am I switched it to a wired setup once my heart did not feel like it was going to stop beating.
So I don’t have the option to remove my saved Amazon wifi networks under my account settings as the option is grayed out. I think it may be that I own a Kindle (says it can be changed there). In any case I found the best way to forget the wifi network on your Echo.
- Go into the wifi settings of your Amazon Echo app for that named echo device.
- Hold the ∅ button on your echo for 5 seconds. You will enter setup mode.
- Press the “Connect” button in your app
- All of the available wifi networks will be displayed. Select the one you want to remove.
- Select “Forget this Network”
- Select “Choose Another Network”
- Select the network you want to use.
- Select “Continue”
You should be good to go!
My house now has two Dots in addition to the Fire TV stick I had. The 1st Dot did not want to setup using the Amazon Alexa app they advise to use. I had to go to the website on my laptop instead. Once setup, I went through the typical turn on this or that and set the Nest to this while testing them. I also tested the voice remote of the fire stick next to a dot. When using the voice remote, the dot would wake with Alexa but after a one ring of blue lights it would turn off letting the voice remote take over. I even held the remote with the dot in between and got the same results. It would be nice if I could tell a dot to control the fire stick also. For me, music from the dots was fine. It’s not super loud or audiophile quality but I usually have music as background noise more than anything.
Just got my 2 dots. I used Gorilla construction adhesive and glued one of these to a blank light ‘plate’ I already had on the ceiling. https://imgur.com/gallery/REKNa
Also connected it to a small amplifier via 3.5mm to RCA and to a new in-ceiling speaker.
Really happy with the result and the range on the echo dot 2 seems great.
The only issue I found was that connected it via a 30 ft USB extension didn’t give the Dot enough power to fully boot, I had to re-arrange where it got power from (closer) and it was fine.
I stuck one of mine under my cabinets with some heavy duty double sided tape. I have those nice under cabinet receptacles that you can’t see so my kitchen dot is not visible at all. Works great.
My Alexa is weird. Sometimes she will find a light I have some times she won’t. I think I got my ex in Alexa form.
Alexa, back porch on
sorry I could find a device listed as back porch
Alexa, turn back porch on
ok
Alexa, turn back porch off
sorry I could find a device listed as back porch

Mine too. I had something called “patio lights” that it found every now and then. I changed it to “patio light” singular and it works fine. The plural caused a problem. Unless I said “the patio lights” it wouldn’t work. Odd.
I accidentally had “mail box” as two words. That wouldn’t work. I changed it to “mailbox” and it works fine. This I understand.
