Q: QuestionI have no Internet at my house I’m looking for something where I can use to hook up my computer and get Wi-Fi

Asked 3 years ago by Richardd.

• A:Answer Hello - this product is for Internet access - there is no Wi-Fi built in. Additionally, no modem or router will work without an internet connection. A router simply takes your internet connection and shares it throughout your home. Hope this helps..

Q: QuestionDoes this unit come with a phone jack? I’m currently renting a modem from Comcast and my phones goes through their modem.

Asked 3 years ago by D.

• A:Answer Yes it has two phone jacks (one for each line you subscribe from your cable company). Provisioning was not straight forward as Xfinity does the internet connection and then you need to call back to get the voice provisioned.

Q: QuestionI have Optimum Internet with voice 400 G service. Will this Arris T 25 modem work ? I will be using it with a eero router and 2 eero extenders

Asked 3 years ago by Anonymous.

• A:Answer Not sure but check with both manufacturers for compatibility. Eero has excellent tech support. I have deployed over 400 Erro 5's and Pro' 6, do not use the beacons and spend the money for the Pro 6, not just the regular 6. Best of luck !!

Q: QuestionHow does one quickly reestablish internet on this modem when there is a power outage? Multiple times I have had to call Xfinity and it has taken +45 minutes each time to get their service to recognize the internet portion. Phone resets just fine

Asked 4 years ago by dharris.

• A:Answer Try logging into your Xfinity account online from a cellphone and under your internet devices restart/reboot the router, that will send a signal from Xfinity's end of things without using the Xfinity mobile app. Another option, depending on how long your power tends to go out, perhaps invest in a small battery backup power supply called a UPS? Typically when the power goes out your internet will still work (because it's coming from the coax cable) so long as the modem and wifi router have power! A decent sized UPS is around $60-$70 and should last a day or so running a modem and router.
