I have a T25 on Xfinity.I tried to logon to the modem at 192.168.100.1 and username “admin” password of “password” returns invalid credentials.I don’t remember changing it, but I probably did at some point.How do I reset the device to default username and password? I’m sure I’ll have to re-register it with Comcast/Xfinity for it to work again, but that’s no big deal.I need to get information off of it, and see if maybe there’s a firmware update available, etc.
I found that my T25 has the following firmware:Firmware Name: TS11.02.057.12_092820_711.PC20.03Firmware Build Time: Mon Sep 28 17:37:14 EDT 2020 Three years seems awfully old. I contacted Comcast, and they supposedly pushed a firmware update, but I didn’t see a change. Does anyone know what the latest firmware version is? Thanks.
reference: ARRIS SURFboard T25 DOCSIS 3.1 Gigabit Cable Modem bought from AmazonXfinity has not fixed or identified any issue on their end. I’ve spent two 3 hour sessions with their support computers, techs, and elevated support. Xfinity support confirms we have the latest firmware, and have reset the modem many times as have I. I’ve tried several phone systems that perform on other systems as they should. (panasonic and Vtech). I’m reaching out to see if this is an issue with the T25 itself, as I have really run out of things to try. Any help, direction would be greatly appreciated.
I have an Arris T25 router in place for a few years and suddenly, it seems that it is blocking traffic coming to my router on Port 21. I need to see my settings, but entering 192.168.86.1 into a browser simply tells me it’s ONLINE; it doesn’t show me my settings.Can you please tell me how to see my settings?Thank you.Len Jacobson
I need to change my WiFi password. The T25 was provided by my A/V contractor (so I wouldn’t have to rent from Xfinity). The Arris consumer care instructions says to access cable modem interface and that does not work (you get an error code, I’ve tried from a PC and an iPad). The Xfinity instructions do not work either. They say their instructions only work with Xfinity provided modems
I see 2 different T25’s with different specifications. Are there 2 versions? On older one and an updated one?I see one with “32 downstream x 8 upstream DOCSIS 3.0 channels, 2 downstream x 2 upstream OFDM DOCSIS 3.1 channels” & 2GB max speed, and another with “32 downstream x 8 upstream DOCSIS 3.1 bonded channels and 2 downstream x 2 upstream OFDM channels” with with up to 10GB speed, without any mention of the DOCSIS 3.0 spec.What’s the difference? Hardware, firmware, or something else? Thanks!
Here's my humorous situation. I'm not at home right now & I didn't take screenshots of my T25. I'm trying to find out the WiFi name & password so I can activate my Xfinity TV Flex box, landline & internet. I don't want to waste your time & no clue what the serial number is & whatnot. Left brochure w/ Arris customer service phone number at home. The other thing is I keep being misinformed what the proper Arris model is by Xfinity, Best Buy & Arris. Basically, I'm not the greatest techie, I need to at least verify the T25 will enable me to use my Xfinity Flex Box for my TV, my Xfinity landline & internet connection. I've purchased (3) Arris modems so far yet I keep jumping back & forth between Xfinity & Arris on the correct model. I can find out the Arris model I recently purchased from Amazon but I'd like to return it if the T25 serves my needs. I realize it's not your fault that I got stuck w/ (3) Arris modems so far. Rather humorous trying to sell m
I’ll try this subject again. The front panel leds on my T25 panel are so dim they almost appear to be non functioning. They only way I can confirm is the unequipped telephone line 2 is several shades of gray darker than line 1. They may have been that way from the beginning, but can’t ever remember seeing a lit LED be so dim in brightness. Just wanted to know if this is normal.
Sorry IFCR, not ICFR. Though I am having no issues, my ISP (Xfinity) was looking at my modem on their end and are stating:“that the IFCR is too high. It is fluctuating too much for the channel it is in” I sent them the info on the channels which they say is in spec, but wont provide me what they see that is leading them to be concernedAny help is appreciatedDownstream QAM DCID Freq Power SNR Modulation Octets Correcteds Uncorrectables Downstream 1 17 483.00 MHz 3.60 dBmV 40.37 dB 256QAM 1473955869 6 0 Downstream 2 1 387.00 MHz 3.70 dBmV 40.37 dB 256QAM 20811007 0 0 Downstream 3 2 393.00 MHz 3.70 dBmV 40.37 dB 256QAM 71266727 0 0 Downstream 4 3 399.00 MHz 3.80 dBmV 40.37 dB 256QAM 69689242 0 0 Downstream 5 4 405.00 MHz 3.70 dBmV 40.37 dB 256QAM 70025644 0 0 Downstream 6 5 411.00 MHz 3.70 dBmV 38.98 dB 256QAM 1457379349 32 0 Downstream 7 6 417.00 MHz 3.70 dBmV
I have been dealing with this issues for quite sometime. And comcast is trying to implicate that there is nothing wrong with the lines yet these error messages are very specific in what's happening. The tech arrived today to tell me that the lines are okay. But the presence of the error codes he could not tell me why they was showing other than the issue is on the modem. Which is a classic move for Comcast. I am asking the community if they have experience this phenomenon. What is the solution?
I am on my 3rd Arris T25 install in the past 3 weeks. Each install works, shows on the Xfinity app as connected, but randomly resets with loss of connection for 2 to 5 minutes each time.Can go several hours without a drop, then drop randomly between 5 minutes and 30 minutes between events.System was working perfectly with the Xfinity leased voice/wifi/cable modem. Nothing changed other than replacing their modem for the purchased T25 non WIFI unit, .I have always used my own WIFI router. This driving me nuts and no support from Comcast other than trying to send a tech for 100 bucks / visit to analyze my end.. As an engineer, replacing a perfectly working system/modem with another modem means my system is 100% normal, unless the spec on the Arris T25 is remarkably different from that of the Xfinity modem. As the T25 is approved for use by Xfinity, what the heck is going on?Thanks
