G18 | G20

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?

Modem too slow

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 top, as were the 2.4GHz and 5GHz radios (under “Primary Home”).

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 launch the app, it says you have t

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 public. If these two

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

how to activate g20 modem

I am unable to connect my printer to the wifi network. I just installed a G18 Surfboard and my printer is a Canon Pixma MG6821. The network shows up and is functioning on my computer. But when I try to connect the printer, it doesn’t ask for the password and then fails to connect. When I try to connect to other networks, it asks for a password. Any idea of how to fix this?

I am having this issue too and looking for a solution.

I just got a new G18 Surfboard Wifi Modem but I am only getting 20 Mbs on speed tests when I am paying Optimum for 300 mbs. I have called their tech support and they are getting normal speeds on their end. They recommended I contact Arris support to optimize the modem settings. In addition to slow speeds, I am frequently needing to restart the modem because it stops providing internet. The light will still be solid blue but nothing connects on Wifi or Ethernet. I am looking for solutions.

Hello. Cablevision Optimum is directing me to you. I am hoping I don’t need a new modem since I recently bought an Arris Surfbiard. Today I requested that Optimum increase my Internet speed to 300 MBPS, which they did and will start charging me for it. But the speed test does not show 300 Mbps for the download which it should, according to Optimum. They said my speed is fine on their end and directed me to the modem manufacturer. When I went on your website, I don’t see the product number of the modem that I bought. I’m trying to determine if I have to get a new modem or not. This is the p/n: SBG00DAY20RT. is this compatible? According to the optimum site I can use a DOCSIS certified DOCSIS 3.1 modem for all speeds.thank you for any guidance

So I just installed this G18 router/modem, and while I can see all the devices connected to my home Wi-Fi when I log in through the web interface, I cannot see them on the Surfboard Central app. The only device I can see is my TV which is connected by ethernet directly to the G18. I want to be able to put content restrictions/filters on my kids devices that are connected, but I am unable to do so because the app does not see them. Setting key words to filter out does not appear to be working through the web interface, so I really need the app to work. Please help! What am I missing?

I have tried a number of times to register a new G20 SBG00DAY20RT using the SN on the back of the device. When I do, I get an error message on the webpage that reads “The Serial Number and Model Number that you entered do not match. Please verify and re-enter this information again. In case of any difficulty, please call consumer support.” I called and left my phone number and other info.
