Cannot Add or Activate a 2nd Pro Wifi Extender

I have been trying for 3 days to get a 2nd pro wifi extender added to my home network.

There is a X8 Gateway modem

There is a Pro Wifi Extender, lets call it #1, with a serial number ending in 72.

It is online and showing in my Xfinity app. I can see it in my Xfinity app and it is showing as connected to my network. 

I was able to add it through the Xfinity App under "add More devices."

I picked up a second Xfinity Pro Wifi Extender, lets call it #2, ending in 19 to cover the other side of the house/basement.
I go into Services tab to add it, and select pro wifi extender.
I get a message that says I already have an extender active.


No matter how many support people I speak to, and try to explain i am activating/adding a 2ND ADDITIONAL PRO EXTENDER, no one seems to be able to help me solve this.

The only way I can get it to stop blinking white slowly is to ethernet it into my actual modem (which then tethers it 5 feet from the modem itself, and thus makes it useless.


How can i actually add my second extender to my account/network so that I have

1. 1 Xfinity Gateway X8 covering the living room

2. Wifi Pro Extender 1 covering the upstairs bedrooms

3. Wifi Pro Extender 2 covering the kitchen and basement underneath it.

Note, both Pro Extenders are in the next room over and no closer then 20 feet to the gateway itself, and are both placed by window.

Hey there, Joshb1! Thanks for reaching out to our XFINITY Community forum. I know how vital it is to have a strong Internet connection throughout every corner of your home. Not to worry! You have reached the right team to assist with this matter.
Please check whether the first one is fully online, then try the "Add a Device" option from the "Connect" tab instead of the initial setup menu to add the second extender. Let us know if this helps!

Hi, I have the same problem and, as the other users said, when you tab on the pro wifi extender, the app shows a message saying "you already have an extender active", or something like that.

All of you customer service people are terrible. He has explained his issue and you all keep saying the same thing. The picture he posted is of the result from following your steps. The service tab add new devices doesn’t works you are a bunch of brain dead bots.  We are canceling our service because of this issue. Not worth the headaches.

From my understanding, you can not add a second “pro” WiFi extender for some odd reason. If you’re wanting to expand your WiFi range, you have to use 1 pro extender, and you can use up to 2 “pod” extenders. I’m going through the same thing right now because i accidentally got sent a second Gateway and Pro extender and figured connecting two “pro” extenders shouldn’t have been an issue. In your case, if your local xfinity store knew you were buying two “pro” extenders, they should have known you can’t connect two of them. I honestly feel like none of the in store or cell workers know a single thing about what they’re selling at this point…. In your case, I would try to go refund your second pro extender and swap for two extender “pods”

Greetings, @user_s2iv4v! I hope your week has been treating you well. Thanks so much for taking a moment out of your busy day to leave a post on our community forum about Xfinity Pro service. You have definitely come to the right place for assistance.

 

I believe that @user_15d0cf provided an excellent description of the Xfinity Pro equipment. There are actually two different pieces of equipment involved.

 

The primary piece of equipment is the Xfinity Pro WiFi Extender (https://www.xfinity.com/support/articles/storm-ready), which is the larger device that also provides a cellular backup in the event of a signal or power loss. You can only add one Xfinity Pro WiFi Extender to your account.

 

The other piece of equipment is the Xfinity WiFi Extender, formerly known as the WiFi Boost Pod or xFi Pod (https://www.xfinity.com/support/articles/xfi-pods-faqs). These extenders do not provide a cellular backup, but they do extend your WiFi signal from the gateway, or from your Xfinity Pro WiFi Extender, if the gateway is offline. You can activate multiple Xfinity WiFi Extenders on the account, and they work with or without the larger Xfinity Pro WiFi Extender.

 

You can find more details about what is included with Xfinity Pro on our support site here: https://www.xfinity.com/hub/internet/xfinity-pro. It will always start out with one primary Xfinity Pro WiFi Extender. Once that is activated, a WiFi health check will be performed to determine if you need additional Xfinity WiFi Extenders. If the health check confirms a weak signal in your home, you can receive up to two additional Xfinity WiFi Extenders to help strengthen that signal.

 

Please let me know if you are having issues activating any equipment, or if you have any questions about your options. Our amazing community is always ready to help, 24 hours a day, 7 days a week.

From https://www.xfinity.com/hub/internet/home-network-wifi-extenders#:~:text=After%20performing%20a,no%20additional%20cost.

Xfinity Pro customers may qualify to receive up to two WiFi Extendersfrom Xfinity at no additional cost. Makes it sound like 2 are able to be used

I apologize, I think there was a misunderstanding due to there being two types of equipment mentioned in XfinityJamesC's response. The larger primary unit is the Xfinity Pro WiFi Extender, of which an account can only have one active at a time.
The other piece of equipment mentioned is our smaller standard WiFi Extender, and a customer may indeed qualify to receive up to two with Xfinity Pro, as mentioned in the article you shared.
