## Questions & Answers

**Q: Is the connector a separate channel? Or do you just use the att connection? Ie is there an Ext that you need to switch to in a remote area of the hous**
A: When I view my extender, as a device, on the gateway It states I have 5Ghz.  It says nothing about 2.4Ghz.
BUT, the device supports is a 2.4Ghz-only device, I am told.
I am running a bastardized network.  My ATT BBGW320-500 is setup to "pass thru" to a TP-Link Mesh AX3000 Router.  I renamed the ATT router to XXXX1 and the TP router is named the old ATT router SSID (XXXX6).  
The ATT extender is located inside, by a Concrete block wall that has my Solar Panel Controller immediately behind it. The Solar Panel Controller is the only device showing-up as connected to the ATT Router.  It still  shows a very weak signal to-from the controller.
The remainder of my home devices (17) show-up on the TP-Link Router and send/receive very strong signals.

**Q: Does this have 3 ports, are they all PoE?**
A: 2 2gig ethernet ports

**Q: Can you use 2 of these for two levels in home connected to the latest ATT router on 3rd floor using a wireless connection?**
A: Yes, I have three of them.  Two additional comments:  1) Use SmartHomeManager to find the weak spots in your home network and place them there and 2) do not overlap them too close together.  Basically your devices (such as a phone) looks for and uses the strongest signal it can find.  If you have two units too close together the devices will hop from one device to another because they both have strong signals and degrade, not improve your service.  I had to move one for this very reason.

**Q: Does the extender still work with the router profiles and downtime settings?**
A: No.  Mine was added as an extender (using the ATT SmartHome Ap) so it doesn't show up as a device that may associate to a profile (it provisions as Network Hardware).  I also have the 4920.  This doesnt show up as an extender once paired but it shows as a device so I may place it in a profile.  The ATT app will setup the 4920 and then say failed but you will find it in the device list and it will extend your network.  In all cases, i found it is best to run an ethernet cable to the extender to allow it to extend the network room to room (5Ghz coverage speeds drop rapidly for devices based on distance between sender/receiver and I didn't want to lose any channel space for the link between the gateway and the extender).  

At first I thought these were junk but then I read more and placed them within 10 feet of each other (and rebooting devices so they will show up as connected to these extenders...and it all started working.  I definitely prefer adding this version (model 4921) as an extender in the app as a hardware device because then I can see what devices connect to it.  

I never was able to reliably use the two ports to connect to end devices. I kept seeing the wireless link between the extender and gateway would intermitently drop even when only 10ft appart.  The computers didnt see it but it would create a lot of lag time.  For me using one port on the extender to tie back to the network was the solution (like strings of Christmas lights).

I am still reading up on the ports on the back and what mode the extender has to be in to work...and if that works for me.

Don't forget to log into the extender and set the admin password.

## Customer Reviews

### ⭐⭐⭐⭐⭐ works great
*by G***B on March 28, 2020*

I have used this booster and it does just like the other I have. This model was not available on the AT&T website. They still show the old model. I received my first one who came to my residence to help with the poor speed I was having with my old AT&T modem. The old one was out-of-date. The new one was better, but I had some dead spots in the house. He installed the Airties 4921 which he said the had just received on their service trucks. The installation went seamlessly. It connects to both GZs without a problem. It does not segregate the two speeds. The only issue I have with this product through Amazon is the price. Buying it off the AT&T truck was $39.99 and it was $70+ through the Amazon seller. Unfortunately, you won't find it on the AT&T website. Maybe later, but not when I checked. Try to have it installed by AT&T of the technician has one and will not charge you a service call.

### ⭐⭐⭐⭐⭐ This works and I don't have any dead spot upstairs
*by B***S on May 22, 2023*

I had to try a few times and finally used the wire and pressed the wps buttons on both and it connected with the smarh app. Took upstairs and after it connected and I rebooted the computers it attached to the extender.Now the TV will stream and the computer transfers files like it did when I had Comcast at my old house. The internet also works like it should with the service I have.Att was not any help. They said I could buy at the Att store and the store said no and I would have to pay the 10$ per month even if I bought the 4971 unit that they give to you when you buy monthly from them. What a joke. I bought the 4921 because it was better and faster than the 4920 that was about $100 less. I am glad I did.

### ⭐⭐⭐⭐ Couldn’t get the 2.4Ghz signal extended initially.  Does not support the guest channel.
*by S***N on June 14, 2021*

I couldn’t get the 2.4Ghz signal extended, nor the guest channel. The set-up appeared easy, however all the trouble shooting over shadowed the initial set-up time. The 5G signal within 20 feet of the extender was strong, but fell off quickly; this was still better than the TP- Link extender it replaced. I found that there was a long time when switching from the router to the extender; had to turn the WiFi on and off on my device to switch immediately.Update: After about a week, I noticed the mesh working almost seamlessly, the way it is supposed to. Apparently, there is some kind of adaption process, either with my devices or the extender. Anyway, it’s working like the previous one and 5G and 2.4 G are available and reasonably strong signals, so I upped my rating.
