T25

My router’s ethernet port is only 10/100. Can I use the second ethernet port on the T25 to connect directly to my PC for faster speed? I would only use the router modem connection for Wi-Fi.

I currently have an old SurfBoard T25 which I use on Xfinity and is perhaps 8-10 years old and it’s a DOCSIS 3.0 modem has a theoretical max speed of 1gbps, recently due to changes in my plan I can get speeds up to 2gbps but I need a new modem with telephony to get it. Now apparently there is a new SurfBoard T25 which is DOCSIS 3.1 capable but the website description seems to contradict itself, this is the picture of the box:Which seems to claim that the max download speed is 2gbps, however on the product page here:Claims “Best for internet plans with up to 800 Mbps” which seems to conflict with what the actual box says. So what is that actual truth here and will this modem achieve up to 2Gbps

It is saying I have Internet but no connection how do I fix it?

T25 modem wants the password of the day for the advanced tab on the web management site. Even after doing a factory reset I can’t get a logon page for admin to change the default password. I also can’t get phone line 2 working for my second phone number.  All calls go to my 1st phone number even with 2 separate phone lines plugged in. Why are two ethernet ports offered if only one is functional? I use two different routers and right now only one can be used.

Xfinity told me to call Arris. T25 I bought and trying to pair with Nighthawk router RS100. Xfinity said Arris needs to activate bridge mode on my T25 modem. Can't I do that myself? And how do I do that?I have no internet access right now so need to use my phone. Missed 2 days of work coz of internet connection.

I receive daily calls from another Xfinity customer who has an X1 gateway.  I have an Arris T25.  When the calls are made to me, the caller’s ID shows up on my phone and TV screen, but when I answer the phone, I hear nothing.  The caller doesn’t hear me answer and says all he hears is the phone continuing to ring.  But I can call that same Xfinity customer without a problem and we both make and receive calls involving third parties.Anyone have similar experiences with the T25 and Xfinity and, if so, how was the issue fixed?  Seems like an Xfinity system issue rather than the modem, but I thought I would check.  Thanks.

New T25 connected a week or so ago lost internet connection then when reset only 1 of the 32 channels now working so can only connect 1 device at a time even with router.

T25:modem drops caller id after about one week of being online.  Only way to restore is to power cycle modem.

I have a 2-year-old Arris T25 modem.  Every two days between 9:30 am and 10:45 am, it reboots without any action by me. It’s been happening for weeks, and always two days between reboots, no more, no less. Is it the modem, or Xfinity?The event log always reads the same:PacketCable Events(Edited content with personal information) DOCSIS EventsFour minutes before the reboot(Edited content with personal information) Just before the reboot(Edited content with personal information) When I check the status, all parameters are within the proper range, but I don’t have a reading from the moment the modem reboots. I'm trying to decide whether to replace the modem with the Netgear CM2050V-100NAS, or call Xfinity. Thanks.

Can I delete the app from my phone once the modem is set up?

I’m using EERO mesh wifi which works GREAT. We have Comcast/Xfinity for internet and voice. We want a router to tie into the T25 for our devices.

Downstream power and snr look good but upstream is bad: I used to get all 5 upstream channels but about a month ago this is when I started having drops:Power is below spec.Is this a cable company issue or is the unit failing to output enough signal for the upstream?

Can the svg2482ac be used as a wireless router with a t25 modem?

I have a T25 modem and XFinity as my cable provider. Apparently I am not getting the internet speeds available because the firmware on my modem is not up to date. There is no information about the firmware version on the surfboard app that is connected to the device, and I'm also not able to log into the modem settings using the IP address and any browser. I just get an error message saying that that IP address cannot be accessed. Of course my warranty on the modem just ran out last month, and I do not want to pay $40 to access the surfboard customer service. Has anyone had this issue where they cannot locate the firmware version let alone log in to their account to update it?I am aware of the disputes between weather it is Xfinity or Arris that has the capacity to update the firmware. I was just on a very long phone call with Xfinity and they are insisting that it is nothing on their end to update the firmware. I have unplugged the modem several times to force a reset, but w

I bought a refurbished T25 but I can't add it to my ISP because it is still registered on someone else's account. Any ideas?

I just bought a new router Wi-Fi combo and it’s not working. I don’t see any green lights like it says

I recently purchased a used Arris T25, I later learned that there is no label, I know I can get the device information like serial number and Mac number if I can log onto the device, it appears to be connecting fine when I attach it to Xfinity coaxial cable, but Xfinity blocks use of the device until activation which requires Mac number.Is there any other way to get the information on this device?

T25 will not show up so I have no service. Xfinity says it's working but I can't find it to connect anything to it

I connected my T25 to Comcast finally and it’s working very well except that I do not have phone service yet. Do I need a separate connection with Comcast or how do I get the phone to work? 

My T25 is supposed to accommodate up to 800 MBPS. Xfinity assures that they’re providing 1000 MBPS, but I get  only 400 MBPS. Please advise.

i recent bought a Arris T25 cable modem pn 613587-003-00. The included power supply Ktec Ks051867 plug does not fit into the cable modem power input. I tried looking on the Arris support website for the model number of the ac adapter but could not find it. The ac adapter is 12V 2.5a so should work. Any help would be much appreciated.

Comcast provided me with two phone numbers. On my previous Arris modem they could configure the modem so both phone numbers were accessed thru one jack on the modem. Comcast claims this is not true on the T25. Must I use both jacks on the modem in order to have both phone numbers?

I purchased a T-25 at Best Buy on June 5, 2024 and successfully activated for Internet and phone service with my provider. Today I returned home and all of the lights were off on the modem and I didn't have Internet or phone service. I tried resetting use the button on back but nothing. Can you provide any other troubleshooting advice or instructions for repair/replace? Thanks

I received a used t25 modem from a realtor friend of mine. I do not have have access to the password, and I don't see it anywhere on the modem. Is there a way to reset it without having the old password? Thanks. 

what router to purchase that is compatible with the T25 modem
