3G Cisco Microcell DPH-154

3G Cisco Microcell DPH-154

I have been using a Cisco DPH-154 Microcell for about 4 years with no problem.  It was CAT5 connected directly to my Xfinity Cable/Modem (running DOCSIS 3.0) ethernet port.  I installed a new 3rd party gateway (Netgear CM1150V Cable/Modem) and connected the Microcell the same as before with an ethernet connection.  Now the Microcell will not register the internet signal from the new gateway.  I now have connected the Microcell directly into one of the internet ports on my Eero WiFi hub and the Microcell connects immediately and starts working.  However, I would prefer to run the Microcell directly from the new Netgear gateway.

 

My question is:  would the reason for no internet signal from the new Netgear gateway be that it runs the latest DOCSIS 3.1 instead of 3.0 which the Xfinity gateway was running?  Is it possible I need to change some setting on the new gateway or the Microcell?

 

Any information would be appreciated.

 

Thanks.

@OttoPylot  can confirm, but if I recall you have to re register the m-cell if you are using new hardware.

Please note the m-cell is on its way out.  If possible connect your phones using Wifi calling.

M-Cell

Thanks for that info, I'll try that.

I do have Wi-Fi Calling setup on my Galaxy S9 but the M-Cell always worked so well for me.

Thx again.

Re: M-Cell

@tralfamadore  - anytime you install a new router and/or gateway you need to check to make sure that it is setup to meet ALL of the MicroCell router requirements as given in my Tech Guide (see link in my sig line). A lot of routers come pre-configured with settings that are not compatible with the MicorCell's requirements so it is up to you to determine how to check and configure. AT&T Support, and us, can not help you because that is beyond what we are here for. Sounds harsh but we do not want to be responsible for messing around with a customer's  internet.

 

That being said, WiFi-C (WiFi Calling) is what AT&T, and us recommend now as @lizdance40  mentioned. Long story short, sales of the MicroCell were discontinued at the end of 2017 because the MicroCell has reached its EOL. The service itself will be discontinued as well as soon as AT&T begins to phase out their 3G network, which is going to happen not too far in the future. If you have a phone that is WiFi-C capable on AT&T's network then I would suggest using that exclusively now and disable the MicroCell (power it off). If you attempt to use WiFi-C within range of a MicroCell that it is registered to you may encounter call quality issues because the MicroCell will have issues deciding which signal to connect to, the MicroCell's 3G signal or your WiFi signal. If you need to leave the MicroCell on, then it is advisable to place your phone in Airplane Mode to disable its cellular radio so your phone can connect to the MicroCell.

Re: M-Cell

Thanks for the comprehensive info; I have decided to leave my setup as is, ie, M-Cell wired to my WiFi router which appears to work fine.  I'll use that until AT&T deletes it's 3G and then move on to WiFi-C.  Either works fine now, I don't seem to have call issues even though the phone is not in Airplane Mode.

 

Thanks again.

Re: M-Cell

@tralfamadore - yep. If it ain't broke, don't fix it Smiley Wink At least you have options and some answers.
