Wi-Fi Modems

I have little to no tech knowledge.  My router is no longer allowing certain items to connect.  Can not authenticate is the what it shows.  I have tried factory reset and still get the same result.  Any tips?

Just bought SBG8300 Modem and Wi-fi in one. It has a Wi-fi cord that plugs from Arris modem to computer.  Now I can't carry my laptop anywhere because it is connected to modem. What can I do?

Do we need to update firmware?  My current firmware is 01.01.137.NCS?

Had to upgrade to new ROUTER/MODEM. G34. Network test results : "HP printer is unable to connect to your wireless router". My MAC filtering IS turned off. DIAGNOSTICS RESULTS show everything good, EXCEPT under settings: no filtering  -FAIL.

I am trying to create my own user id and password but I get this message: Invalid user name or password, or your access has been locked due to multiple failed login attempts! I’ve re set my modem 3 times, cleared my cache and still locked out. 

I just got my WiFi service installed with Xfinity and I have my own Arris surfboard modem/router. The WiFi won’t seem to connect and the blue light on the WiFi signal keeps blinking. The WiFi does not seem to be connecting and won’t work on my phone or laptop. How do I get it to connect? Unplugging it and restarting it doesn’t work. 

On a fairly regular basis my G34 Wifi router/modem will stop broadcasting the SSIDs for 2.4 and 5. I’ve tried restarting and a reset. Nothing seems to make it stable. It still passes wired traffic and I have a TPLink AP that broadcasts without issue. None of the built in diagnostic tools are providing answers. 

greetings, I recently purchased an ARRIS surfboard SBG10 through Best Buy. When I was researching this item, the website indicated it was a modem and router combo, however, when I picked up the item, the description on the box only said ‘wifi cable modem’. When the technician came to install my service, he informed me that this was only a modem and didn’t have the router.I checked other images, including the ones on the ARRIS website, and the box description said ‘cable modem and wifi router’ clearly for product SBG10 while mine does not say this.My question is, how can I verify the device I purchased is a combo gateway instead of a just a modem as described on the box? Thanks

Have a SBG 8300 gateway and I am unable to connect to my work server. Internet connection is fine. I unfortunately have basically no understanding of how this works. My IT person says it’s a xfinity problem, xfinity says it’s a modem problem. Which I believe because I can log on everywhere but home.  

i currently have xfiniti 200mb service to my home when i do a speed test from any device hard wired to the modem its great i get that speed. When i do a device speed test that is on wifi I only get 20mb at best upload is consistant for bot WIFI connected devices and ethernet connected. Why is my WIFI download so low? how do i fix it.

Ethernet works, but I don't see WIFI.  Friends see “my” WIFI on their computers/smart phones. (I don't have a smart phone) When I log in to Surfboard, it says unsupported Browser.

Xfinity has been bugging me about my ancient modem so updated with Arris SBG10 modem/router, which I got from Ebay.  Overall setup was straightforward and it basically works, but DHCP service is weird.  I add entries to the list of reserved clients, following the “add”/”apply” protocol.  I get the refresh/log back in routine as described in the tutorial.  But the entries don’t stay on the list over refresh/reboot. I also tried changing a linux computer on my home LAN to Fixed IP, but the SBG10 doesn’t consistently accept that address. Sometimes it does, sometimes it assigns a new address.  My SBG10 also seems erratic just showing all attached clients.Is the SBG10 known to do this sort of thing? Perhaps I just got a bum example?

Randomly at least 2x a day, the wi-fi loses connectivity. At the same time, the ethernet connection works as expected. I then have to restart the modem to restore wi-fi connectivity. Event logs show this: ti_dhcp6c: 72001011-DHCPv6 - Missing Required Option 82    11/21/2022 19:23:27    Criticalti_dhcp6c: 72001011-DHCPv6 - Missing Required Option 24    11/21/2022 19:23:27    Criticalti_dhcp6c: 72001011-DHCPv6 - Missing Required Option 82    11/21/2022 19:13:15    Criticalti_dhcp6c: 72001011-DHCPv6 - Missing Required Option 82    11/21/2022 17:58:05    Criticalti_dhcp6c: 72001011-DHCPv6 - Missing Required Option 24    11/21/2022 17:58:05    Criticalti_dhcp6c: 72001011-DHCPv6 - Missing Required Option 82    11/21/2022 17:46:24    Criticalti_dhcp6c: 72001011-DHCPv6 - Missing Required Option 82    11/21/2022 16:48:51    Critical Firewall logsFW.IPv6 INPUT drop    1805 attempts    11/22/2022 23:29:37    F

Working on my dad’s SurfBoard 6700. Using a mac via Safari. I can access the modem after bypassing the secure connection warnings, then entering the logon credentials. However, I get his page displayed  Sure can't do anything with THAT.Something is blocking the full page access.

When I try to connect to the admin page, I get this message: Secure Connection FailedAn error occurred during a connection to 192.168.0.1. Peer using unsupported version of security protocol.Error code: SSL_ERROR_UNSUPPORTED_VERSION    The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.    Please contact the website owners to inform them of this problem.This website might not support the TLS 1.2 protocol, which is the minimum version supported.  It happens on every browser I have. I saw a similar post and the person was told to disconnect the coax cable. Clearly this doesn’t work, because the problem is that the admin page has security issues. I don’t really feel like paying $40 for a live chat, and I can’t time travel back to Internet Explorer where I could override security flaws, so, what are the options?

Upgraded my modem/gateway/router from SBG6900 and G34 and immediately had problems with my TIVO mini’s being unable to connect to the Host DVR.  Problem lasted a couple of weeks with no help from ARRIS (assured me nothing internally was being blocked) or TIVO (couldn’t tell me what protocol they used for discovery).Problem was solved when I discovered the setting for “Zero Config” (Bonjour type discovery) under Advanced > Device Discovery > Zero Config was disabled.  Enabling it allowed my TIVO mini’s to immediately connect to the host DVR.  Note that this setting is on a page that is mainly about UPNP.This could affect anyone else who has printers or other devices that use the Bonjour Zero config capability to connect to one another.

Why does the Surfboard Central app keep saying no network available? But it show all Wi-Fi units online. And can't do a speed test .

Sbg8300 isn't recognizing the 2 play fi devices that worked fine with my previous router. I run the setup routine but they don't show up, have done factory resets on both devices.  Am thinking there may be something in the surfboard setting preventing the discovery of them.  Would appreciate any suggestions or insights. Thanks in advance.

I just setup the G36 Modem/Router & the Troubleshooting > Diagnostic Tools test fail while connected & online. This is with an Ethernet connection.Why is it failing?

Is there a setting that must be enabled to provide normal speeds through the 2.5g port? I’m unable to connect to the internet via the 2.5g port on the back of my G36 with more than minimal (under 1mbps) speeds.  I have Xfinity Gigabit (1.2Gbps) and with the 1g ports I can routinely get ~1Gbps with a wired connection. When I plug the same patch cable (both Cat5e and Cat6) into the 2.5g port, there is no signal to my office 4-port switch, and almost no connection speed to my laptop 4ft. away from the gateway.  Am I wrong in thinking that 2.5g port should operate the same, and better, than the other four ports? 

Can removing the 2.4GHz link increase 5G speeds?

Hi all, So I have a SBG7400AC2, and have added a number of devices to the Reserve client list..So why is the Reserved IP Client List not updating on the new devices, even after days,yet if the device is turned on it does get the assigned IP. So it seems that both Attached Client List and the Reserved IP Client List are not showing correctlyas i have some 60+ devices and I see onlu 25 at best Any Ideas, seems the software is upto daye a do not se any updates for it Any help would be appreciated M

Ethernet. Ports not working there blinking red. Can't connect firestick say connected but no internet. Same thing with Mac computer 

Ran into an issue yesterday when out of nowhere my Router dropped the wifi connection to all my devices.  I went to the step one solution and power cycled the router to see if that would bring back my networks and nothing.   Turns out the router had dropped the custom wireless connections and replaced them with the default network names.  I can access both the 2.4Gz and 5Gz by using the default password on my modem.  My Mac on the other hand cannot connect to the default 2.4Gz, only the 5Gz. Seems like a simple login to the Gateway Modem manager to upgrade the firmware could fix the issues, and let me create my own network names, and passwords again.   But I cannot access the Gateway Manager.  Firefox, Chrome, Edge, and Explorer all block this attempt.  This is both when the router is connected to the coax cable, and when the coax is unplugged.  All of the browsers above give you the "This site cannot be reached" with no option to pro
