Modem - General

I have just switched Internet, TV and Phone to Infinity from Verizon (also wireless but that it not relevant here). The Xfinity service team installed its proprietary modem-router into which they plugged my telephone cord into the back of the modem-router. The phone works fine as do the modem and router. I would like to buy a modem-router rather than rent the one that I have received dfrom Xfinity. But I want to be certain to buy the right modem-router -- one into which my voice telephone can also be plugged so that it also works. I would be most grateful for recommendations of the right model modem-router with voice phone plug for my application. If you need more information to respond, please let me know what I have left out. Many thanks. Peter

I purchased the modem from Best Buy because my modem was acting strangely. I did not get a chance to install the modem until after the bus by return policy expired. Best Buy recommended me reaching out to you about getting a refund because they were unable to refund or replace the modem. Please contact me at 484-651-7129. If you need to discuss this or please reply to this request and I will follow the steps that you provide. Best Buy told me that you would reimburse or replace the modem due to their return policy. The modem is an SB 8200 and was purchased on January 4, 2025 or $169 plus tax from Best Buy and wyomissing PA store number 580

I am using the default 2.4G SSID and password. How do I change them to my desired WiFi name and password?

I purchased my SB6121 from an authorized retailer (Staples). Recently while talking to my internet provider (Comcast), they claimed that it needed a firmware upgrade and asked me if I would allow them to do it. They did not tell me at the time that they would be stealing control of my personally owned hardware from me. After installing the firmware upgrade, they proceeded to tell me that there is a problem with the hardware and tried to sell me their modem. When I log into my modem (at IP 192.168.100.1), there is no longer a “Reset All Defaults” button. This is unacceptable and I want control of my hardware back. Is there a way I (or you) can roll back the hacked firmware they installed and return control of my hardware to me?

My husband reset the router to factory settings which is a TP link one and now our modem won’t work and our internet won’t connect. We have no WiFi connection through our internet service and Cox said we need the information from this modem provider

Change username and password on DG6450A/NA. I did it once but now I keep getting wrong user name/ password. I would like to change it on all my devices

Hello, Would like to reset the pwd for my wifi Thanks,

How can I change the original e-mail I used to register the App?

I never received a confirmation email for my order on the arris website story for an S34. After completing the order, I was shown a page with my order number, but never received an email. I tried to email the support address, but my email was not delivered for some reason.

I know this is a SB Board, but I have a CM8200A I am using (same as the SB8200 in some ways). My question is more about the Web Interface rather than the modem itself. I am use to LinkSys web interface with I find palatable. On the CM8200A Web Interface, I seem to be missing a “Clear” button for the event log and the status page. A clear button helps me to see exactly what is going on without having to look through the clutter (if I may). There are events dated 1969 which I understand is standard if the device does not have it’s clock set. On the bottom of the Status Page, the clock time seems to be 7 hours ahead of my local time. Possibly not getting a time signal from the ISP, don’t know. OK… enough of that. Now for the question… Is there any way (other than a factory reset) to clear the log and the status? Thanks in advance.

Hello. We have Centurylink DSL with a download of 17 MPBS. I am trying to use the following: Wireless Setup: Wireless Schedule Utilities: Web Activity Log Advanced setup: (No Secure WIFI) Access Scheduler; Service Blocking; Website Blocking (device) Century link modem router combos mess up using those features. For example, if I try to set the Access Scheduler on my daughter so she is cut off around 1 AM it causes all of the connected devices to be cut off. Also, the Web Activity Log is not good it contains jargon I can’t decipher and does not have a good history. Also, when I use the Wireless Schedule to turn off the entire wifi at lets say 12 midnight before it is even that time it cuts all connected devices off. Would anyone please know of a modem / router combo or a modem / router via bridge etc. that might achieve this? Thank you.

Hi there, I have xfinity and am looking to get a good modem/router combo that is not compatible with their 3D mapping. Can someone tell me what the best arris options are for gaming and downloads? Thank you!

I downloaded the app, followed the instructions, have centurylink all ready to go, yet it keeps freezing on the app when I try to use the WiFi the modem is supposed to to put out, and cannot use the app without the WiFi. What do I do

The model number and serial number do not match. I cant get anything done!

I was wondering why my wifi went out. I go and check my wifi box and came to see that only the power and the Downstream icon was blinking. I own a SBG7600AC2 and when I reseted the box, only the power, downstream, wifi, and signal appeared. I couldn’t figure out why the down and upstream couldn't get a signal. Please help me!

I have a new Qualcomm portable wifi unit. Desperately want to use it. But if I'm lucky enough to get through to 192.168.100.1. The text in the booklet that came with it, could only be ready with a very good magnifying glass. I can type in admin admin I know my SSID But I can't read the rest of the info to fill the boxes to set up my portable router. Can anyone help me, or do I need to forget this and get my money back???
