Wi-Fi Modems

Not sure what’s going on but some connections to my home network are forwarding to an external captive portal site - connectivitycheck. I did not set this up. How do I stop this from happening? This is not a wifi hotspot - it’s my home network. Not every connection gets forwarded to the external site - only some of them. And this is not a wifi problem - the wifi connections in the router are working fine. It’s some of the ethernet connections that are getting forwarded. I know they are connected to the internet because they are bringing up that external page, but they show as not connected because that captive portal appears to be blocking the connection. I am on Xfinity and the external connectivitycheck captive portal is bringing up an xfinity login screen as if I was on a wifi hotspot, which I am not. But again, the wifi connections and some ethernet connections are working fine. And all connections show as connected via Advanced IP Scanner even if they are blocked by the portal.

Two questions actually: 1. How do I change carriers on my surfboard 7400? 2. My adult son turned the lights off on the 7400 so how do I turn them back on?

The bottom of the model provides WAN & HFC, but not CM. I need this to activate my WiFi through Xfinity app. 

i sent in a request for help.  I can’t find how to get a live chat again, the page just says it’s open.  Also, this modem is driving me nuts!  It doesn’t work and I’m past the time for returning it to Amazon.  HELP!!! how do i get a replacement of a different model?  Too many people have this problem for it to be my problem.

On the G54, can you manually set 5 MHz to a specific channel?

my building is looking into an arrangement with Frontier to install FIOS in my building. We currently have xfinity and I have an ARRIS G36 modem. Its is working rather well now so I wondered if I could keep it if and when this building goes over to  FIOS. I can’t get much of an answer from ARRIS and after a long hold, I was able to speak to a tech service person at Frontier, who told me that the only modem compatible with their FIOS is the ARRIS NVG443B. But that one isn’t even listed on ARRIS’s website. Anyone know anything?

G34 ipv6 setup 

internet quit working suddenly on surfboard SBG7400AC2. Never have had any issues until tonight.

I’ve been using an old surfboard modem with google wifi mesh for years but never seeing speeds over 150mbps. Xfinity told me this was because my modem was outdated and couldn’t support higher speeds, which by the specs is probably true. so I upgraded the modem to the s33. With speed tests, I was now getting 800mbps at the modem (what I pay for), but my WiFi was still topping around 200mbps on devices nearby. I decided to ditch the mesh altogether as my house is not that big, and got the g36 modem/router instead. Now on 5g, I’m getting WiFi speeds between 350-450 when near the router, down to 80mbps two rooms over. On 2.4g I’m getting 40mbps max. Is this really the best WiFi speeds I can get with the g36? 

I have pressed and held the button in the little hole and waited until lights go out.   Then waited until it came back up.  I have internet access, but the login on the SBG10 is not being reset after multiple attempts.  I read about a suggestion to reset the gateway, but do not see directions on how to do this.

Furious customer here!! For several MONTHS I have been battling with Arris for a refund for a modem that failed within one year of use. They refused to refund, as the product was not purchased directly through them. (A very unfair policy that leaves most consumers at a loss, as most merchants will not accept faulty tech merchandise and will just tell you to contact the tech company directly).So, they sent a replacement instead. This sadly failed to work within ONE week of use! Clearly there is a problem with their products (as I’ve now seen from lengthy searches on this forum and online, including a class action lawsuit in 2017). There seems to be a significant number of issue with their products and compatibility with Xfinity.Compounding this, the customer service experiences I have had have been HORRENDOUS, including empty promises to return calls; no direct line offered to the senior rep, Priya, I have been fruitlessly working with, requiring a minimum of 30 minutes

I just installed a G36 modem on my Comcast ISP (setting it in Bridge mode).  After the fact I discover that many others have had connectivity issues with this modem, with the finger pointed at the firmware. And the finger pointing solution seems directed away from Arris toward the ISP. My firmware is what came installed when I bought the unit late last year : 01.04.288.01.01.NCSDoes anyone have newer firmware than that? And how bad are the connectivity problems?   

I cannot the admin portal up on wired connection.  Looked through all positions - updated firmware, reset modem. User name and password found on the mobile app used on login page of admin portal. Splash screen stating “login first” appears for a moment and then back to overview page with login. Using chrome, which G36 doesn’t like so also tried MS Edge - same result. Need to check advanced settings in G36 as my child’s Yoto player no longer will connect to g36. 

The only change I made was factory reset. The Factory reset completed successfully. After reset the wifi SSID now reads ARRIS-2A8D, so I know it made some changes. I can access the iternet from this win11 desktop that is “wired.” But I cannot access Web Manager.  I haven’t used this modem router in 3 years, but my main router failed. I’m only using 2 ethernet cables. one coming from the outside fiber optic line that adapts to ethernet. Other ethernet cable is this plugged into this desktop. errorThis site can’t be reached192.168.0.1 took too long to respond.Try:Checking the connection Checking the proxy and the firewall Running Windows Network DiagnosticsERR_CONNECTION_TIMED_OUT I’ve tried downloading Arris surfBoard app on iPhone. I’ve trie

I just brought a G36, now being told I need a firmware update to 1.05I see a lot of frustration out there about this.Xfinity tells me they do not do it. Not true I know.Where do I go from here?Bottom line for me should I just return the g36?Sorry if this is old news. I should have done better checking before buying it.

Hoping for some guidance here on what to do. Out of nowhere this morning, G36 just decided to stop working. We have Xfinity internet, they show no outages in the area. Tried power cycling the modem, didn’t help. Tried the reset button and holding that for 30,60 seconds, didn’t help. Not sure what to do here going forward, Cables all check out and are connected just fine. 

I bought my G34 September 2023 and it has been working on the Xfinity Network until 2 days ago, it went offline all of a sudden. I have disconnected from power source, tried to reconnect via Xfinity app and it just continues to be offline. I called Xfinity and they were no help, they want to send a technician to my home and charge me. I work from home and internet access is crucial. Please advise what I can do to get my G34 back online with Xfinity Network. Thanks. 

We were having problems with our G36 locking up. After numerous times of it locking up I unplugged the unit to let it reset. After turning the power on all it does it blink blue rapidly. I pushed the reset button and nothing has changed. Can you instruct me on what to do to fix the problem?

I’d welcome any insight as to what may cause the 5GHz WiFi signal on the G36 to regularly provide slower (19, 27, 35 40, 65mbps, etc.) network speed than the 2.4GHz (72mbps). 2 Coax cable connected devices meet network speed service levels (Network is WOW, Service Level is 300/20.) Only two devices connected to 5GHz channel (1 Android phone, 1 Tp-Link Mesh WiFi Extender.) Other factors for consideration:Both frequencies are using non-congested channels in my area (they are the only signal on their respective channels according to the WiFi Spectrum analyzer.) Bandwidth selection set to Manual: 2.4Ghz is 20/40; 5GHz is20/40/80 Default settings for MU-MIMO enabled; DFS disabled Distance from the modem/router does not change these results (10 inches up to 50 feet.) Rebooting the modem/router does not change these results.

I purchased the combo through Amazon. As soon as the window closed to return (1 month), it started dropping connections. After 6 service provider visits and nothing was resolved because the modem router would work and as soon as the tech would leave, it started dropping connections. Sparklight cannot update firmware and Arris won't. This is the only item that I have purchased from Amazon that is absolute junk and not cheap. NO ONE will address this issue.

I have an Arris SBG8300. What make and model extender should I buy?

Wifi starts out really well (350mbps) then after a while it consistently drops  to a crawl  (~10MBPS ). See below, there is something very wrong with my Internet. Thousands of attempts within minutes (average of 6200).  Once I disconnect from wifi and reconnect, it goes back to normal speed until its gone… all over again to a crawl and repeat every few hours.  Advice appreciated 

my internet is very slow 35 dowload and 21 upload 

I have a 34 gateway and the wifi and ethernet speeds are extremely slow compared to what I pay for. I have a 600mbps plan and I get 150-200mbps on wifi and 100 on ethernet on the second port as the 1st port I only get 50mbps if anyone has any ideas I would be greatful.

I bought a new arris sbg8300 modem. When using it every 48 hours it disconnects the internet the light is still green and I have to unplug and plug the modem back to work again. It disconnects exactly same time all the time. I was thinking because on my arris app there is zero my devices connected, it thinks nothing is on so it stop connecting. I can’t add any devices on the app because are no choices to add my devices. When logging on arris on my computer it show what is connected. I rest the modem and that didn’t work. Any idea?
