G18 | G20

QR code on device not working for set up

After a comcast outage, my G-18 started rebooting every 5-15 minutes.  I have opened a ticket with Xfinitity, but they seem to think the router software might have been updated and that might be the cause of the problem.  They then said that since it is not their router, they cannot help me.  I pointed them at https://arris.my.salesforce-sites.com/consumers/articles/knowledge/Upgrading-Firmware-on-Cable-Devices saying Xfinity as the DOCSIS operator would be updating the software, but they seem to disagree.  Which of you is right?Here is the thread: https://forums.xfinity.com/conversations/your-home-network/modem-keeps-rebooting/6936189899d8a96371b4e10eI have posted the software version, WAN status, and Event Logs from the G-18 user interface there.  Does anything stand out to you?I believe th

I just switched and updated to the G20 modem/router. I have been able to connect my phone to it but no other devices are able to connect.  When I look on the dashboard, it only shows my phone. The password is correct but it won't connect. How do I fix this? 

I installed a brand new G20.  Since then I've been having issues with location services on betting sites but only on my desktop.  Rebooting the gateway fixes the issues for a little bit of time but eventually the issue returns.  Its happens on multiple sites.  Sites like Google Maps are unaffected.  FYI I am not using the onboard WiFi radios - they are disabled - because the modem is in my basement and I have other APs that broadcast an existing WiFi network that I have been using for a long time. 

I put in admin and the password in the setup booklet and it is telling me it is wrong. How do I login to the modem?

Arris G20 combo. Can’t set up via app cause the app is rubbish and doesn’t work at all.  I can only get so far, and it fails when it wants me to log into the network using wifi when I AM LOGGED IN WITH Wi-Fi to THE NETWORK. Spent over 2 hours fighting and troubleshooting til I realized it’s rubbish and not to be used. However, when I reset everything and tried to log in to the web portal, I cannot do anything there either, as it wants an email and password I don’t have, and there is no option TO SET ONE UP.  The whole process is not user-friendly  at all when things fail or you get errors, you’re left out to dry.  I can’t do anything, all I want to do is change my network name and password from the default...But I can’t even log in anywhere or set up an account. 

Modem too slow

I finally was able to change password, after 30 minutes of trying, but need to change some settings of my G20. How can I do this?

I bought an ARRIS Model G20 Modem. and there is a problem when i went to activate the modem through Xfinity. after i gave them all the info i was able to connect to the internet, the problem is Xfinity cannot see my modem and when i’m on the Xfinity app it says i am off line. when i goto the web gui for my arris modem i goto Gateway > Hardware > System Hardware and scroll down and see this...Device Condition:Used….does this mean my modem is used…...i am wondering if someone had this modem before and had the same issue and ARRIS just checked it and then just repackaged it and shipped it to a retailer…...i was chatting with the xfinity guy for over an hour trying to get it them able to see it. they offered to send a tech out but i do not want to take time off of work if i don’t have to….has anyone ever had this issue or when you look in the web gui and goto the location i wrote above and does it say USED or New.

I have and Arris G20 moden/router where the Wi-Fi drops after about a hour of use on all my Samsung devices. They all show that the internet still connected,  but it really isn't connected because you can't use anything that's wifi or even do searches.  My Google (android) TV is not effected and stays connected. Am I missing some setting that then allows my samsung devices to stay connected, or is my new Arris not compatible with Samsung products. 

New G20 arrives this past Wednesday. Hook it up through Xfinity assistant.Thursday, all is well.Friday Intermittent connections issues. On the phone with Xfinity for hours, they’re sending a guy out on Monday.I’ve read the other forum posts, this is a common occurrence. Only, it’s Sunday right now and my G20 has been solid blue for the past couple hours. I just had to factory reset the gateway. On Wednesday I set up the G20 through the web app, then logged into the G20’s GUI interface separately using the Brave browser. Deciding I didn’t want an app to override my access to a G20 I had direct access to, I requested to have my app account deleted.  Incoming conjecture: deleting the app account interfered with local account management creating frequent modem reboots. For me the tell-tale sign the issue was with the G20 and not Xfinity was that when I logged into the GUI web access on Friday, “Wi-FI” was red-x’d out at the

Hi!  I have a new Arris G20 Surfboard Wi-Fi Cable Modem, I have been able to add all of my phones and laptops to the Wi-Fi, but not my HP Envy 4500 printer.  I get the message your HP printer is unable to connect to your wireless router, and that I must add the MAC address of my printer to the list of permitted devices for my wireless router.  How do I do that?  Melanie

I'm trying to set up this Surfboard Modem/Router - I got it activated and am on the internet. I go through the setup process in Surfboard Central and get to the registration part (meaning I logged into the internet, connected my SSID, and then the next step), I get the above error. If I troubleshoot, it tells me to relaunch the app and try again, then to restart the gateway and try again. I’ve done all of these many times at this point and get the same issue at the same point over and over. It tells me to call support… I have called the number a dozen times and it disconnected right away - nobody even picks up even though I’m in the support period. I can’t register the device to access what I’m sure is a warranty of some kind to be able to access live chat support. Like… it should NOT be this hard and I should be able to talk to someone to be able to access the device I now own. It’s not like this was cheap.  The only thing I can think is that when you la

I raced home. I had ten minutes of pushing live chat. Live chat was open. Kept pushing while nothing happened for ten minutes. Now it’s closed and I still don’t have WiFi for my dogs automatic feeder. Needed set up help. This garbage is going back tomorrow. I don’t have time for their nonsense. I work 13 hours on eastern time. They should have put that on the listing. Not convenient for eastern customers. I’m already over it.

I recently factory reset my g20 router (I've done it many times before) but instead of seeing the generic "E09-G20" device name listed on the public wifi list to restart the router setup process, I saw a bunch of wifi names like "wave_10" or "wave_11", etc.  I figured that it must've been my Arris, and I was able to successfully login to one of them to restart the process of changing my Arris interface settings on the website. I successfully set up my 2.4ghz and 5ghz channels, and on the network list on the website, I successfully disabled the other random wifi channels named "wave", etc. However, on the public wifi broadcasting list, visible on my phone or desktop computer, I still see two channels named "wave_22 and "wave_44". They aren't listed on my Arris router homepage, and the interface website only shows my 2.4ghz and 5ghz networks as being active. However, it appears that anybody can connect to these two random wifi channels that are being broadcast to the pub

I have spectrum cable and it will not connecr to tvs i contacted them and they say it working on there end

A week ago my G20 started to reboot itself every 3 to 5 minuets . I contacted My ISP Comcast about it and they checked the signal and it was sending the proper 600 megs I am supposed to receive , but then in about three min the modem would reboot itself and reconnect again for about three to five minuets I cannot use this modem like this I would like a refund or replacement unit.     thank you.

I installed an Arris G-20. After about a week it started cycling through reboots to connect.  It won’t stay connected.  Xfinity says the device is faulty. 

I’m not understanding the instructions for  installing 

Hi my company now wants everyone on video for teams calls which can sometimes be 30+ people.My internet is struggling with this many videos feeds. Is there a quality of service setting for the G18 device so I can prioritize teams over other apps?Or do you recommend a different device? Please help! Thanks!

I’m trying to connect our G18 router/modem to our Spectrum service. Everything is plugged in, solid blue light is on. But when we go to connect to the Wi-Fi there are 40+ different wifi names called “wave_(1-40+)”. The Wi-Fi works once connected to one of the names but how can we make it just one and get it password protected? 

My new (< 60 days) G20 died.  No LED lights when plugged in at all.  I want to return for a replacement.    Need RMA.Surfboard.com is less than user friendly as the link for live chat suggest the surfboard community.  

Used an IP address to activate my ARRIS surfboard Wi-Fi cable modem G20 and now my chrome browser will not return...or I should say I don’t know how to back out of the IP situation. It is creating an inability for Wi-Fi calling and Chrome interface is no longer available. I am not a techy by any means, age 78, so excuse me if some of my terms are out of whack! ARRIS did warn me that there would possibly be consequences but I had no choice but to continue...much to my demise
