Wi-Fi Modems - General

I have a device model ARRIS VAP4641 (Hostname: VAP4641‑9cf2) with software version: 08.03.017.07.This device was originally provided by the ISP TIGO Guatemala, but it is now my personal property. I wish to use it as a WiFi access point or repeater in my home network.  I have accessed the web interface, but in the “Wireless Interface” section, the option shows *none*, preventing me from enabling the normal WiFi radios.I kindly request that you provide the compatible generic (retail) firmware for the VAP4641 model that allows reactivating the WiFi functions (2.4 GHz and 5 GHz) and configuring SSID/password, ideally version 08.02.xxx or equivalent “GA‑Generic.”Device information:- Model: VAP4641  - Current software version: 08.03.017.07 

Router not connecting to the internet. please help 

I’m looking for a combo modem and router to replace an ARRIS TG1672G that I have from Spectrum. They say I need to upgrade my equipment but no longer offer any combo devices. I need the combo due to very limited space on my desk. My Ooma Telo currently connects directly to the TG1672G with a ribbon style ethernet cable. I’ve looked at the G18, G20 and G34 “Wi-Fi Cable Modems” on the surfboard website but under “Digital Voice Service Capability” they all say “NO”. I interpret this as meaning I couldn’t use the Ooma Telo with any of them. Am I correct or just misunderstanding the terminology? I believe Ooma Telo varies from other VoIP services like Spectrum’s own service, I certainly don’t understand the technical aspects of either. If a moderator or other in the know person could clarify this for me it will be very much appreciated. Thank You!

I recently installed some Parental Controls and have seen multiple attempts to access blocked sites. I’m pretty sure it is NOT anyone in my household because I’ve been home alone while this happened.  Here are a few of the messages: What do they mean and should I change passwords on everything?US profile assignment change.

All 4 fail to light leds despite showing “active” on the admin screen. What an I do to fix? I have already done a factory reset to no avail

Hi, I am going to purchase either the G20 or the G34. From what I’ve read the G34 is the better one, but it’s $50 cheaper than the G20, so I’m confused as to why the pricing isn’t the other way round.  I don’t need the extra two Ethernet ports and my apartment is only 600 square feet, so the G20 would be better, but it’s $50 more.Can anyone explain why the G34 is cheaper? In simple terms as I find it hard to get my head around all the info 😊thank you in advance 

Good morning,I am using modem Arris DG3270AI am trying to change my Wi-Fi password by logging into the admin panel at 192.168.0.1, but I don’t know the login credentials. I already tried admin/admin and admin/password, but neither worked. Could you please tell me what the default account credentials you usually set up are? I already contacted my internet provider, and they told me I need to reach out to the manufacturer.

We have a TM822G router. we bought some cameras that we want to attach via static ip but the router’s dhcp settings is using the entire range and the lan sttings are all greyed-out. I tried resetting the router but the dhcp settings are still un modifiable. How can I change the settings?

I set up and activated  The ARRIS wifi cable modem and router. But the wifi is only  working with the ethernet cord. 

I am adding a VoIP phone and having trouble connecting by Wi-Fi or Ethernet.  The phone service provider gave me the following instructions, but I don’t see an address to log into. Where do I log in and are the instructions correct? The modem is an Arris 3635.Just to follow up regarding connecting your VoIP phone.  To rule out anything something else, please log into your router.  To do that, take a look at the back of your router and it should have the login web address, the username and the password.Once you have logged in, look for a tab labeled Advanced, NAT or Firewall.  Then look for SIP- ALG and/or SIP Helper.  Once you find it, disable it and make sure you click SAVE/APPLY.  Then reboot your router and your Yealink phone.If after a reboot, the phone is still not registering and it is displaying NO SERVICE, I would recommend that you call SparkLite customer service and advise them you need to disable SIP-ALG so you "can use a VoIP phone — it’s blocking SIP registration."

I just finished setting up my new router+modem and I can’t connect to my 5g internet even though I put in the correct password. I can connect my 2.4G internet though

Router password needs to be reset

Hi, I just recently switched internet providers (Access to Sasktel) and Sasktel gave me an Arris router. Now my google homes will no longer connect to the Wi-Fi. I have factory reset them and it keeps giving me the same messages. “Disable Access Point/AP Isolation and Enable UPnP.” I can find UPnP in the router settings and it is enabled however I can not find anything called Access Point or AP isolation. Where could I find this option or is it labeled as something else? Thanks.Model: NVG448BQ

Hello I tried accessing the management interface by entering 192.168.1.1 in my browser, but the system prompted me to enter a serial number. I entered the serial number on the device, but it kept saying it was incorrect. Yes, I tried using the default username and password, but the system still asked for the serial number. I used a paperclip to hold the reset button on the device for about 10 seconds until it restarted. Then, I tried logging in with the default username and password. The issue still persists after the reset. Please help me resolve this problem.
