Windows 7 with DOCIS 3.1?

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.

SBG10 not remembering reserved client IP address

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?

Arris G36 Wi-Fi goes offline intermittently. Event logs show missing option 82 and 24.

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    Firewall BlockedFW.IPv6 FORWARD drop    150 attempts    11/22/2022 23:29:37    Firewall B

Modem access issues beyond secure connection 192.168.0.1

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.

Admin page doesn't work

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?

G34 blocks TIVO and Bonjour (computers/printers) "Zero Config" discovery by default

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.

sbg8300 doesn't see play-fi devices

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.

Slow connection through G36 2.5g port

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?

SBG6900-AC Gateway Manager issues

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 proceed to unsafe gateway, or anything of that sort. Sa

HP Printer won't connect to my G34 via WiFI.

I’ve spent a long time trying to get my HP Deskjet 4155e to connect to the WiFi on my Surfboard G34, which can’t seem to find the networks I’ve set up even though I set the printer right next to the gateway.  When I called the HP tech support, they keep telling me to call the ISP and get them to separate the 2.4 GHz and 5 Ghz networks, but Spectrum says they can’t do that because I own the modem/router.  What exactly does it mean to separate the 2 different radio networks, and can I do that? So far, I’ve tried turning off the 5Ghz networks, but that hasn’t worked.

DG860a Wirh Blinking Ethernet Ports

I am using a Arris DG 860 a modem with spectrum Internet. Yesterday I had no Internet access, and when I went and checked the modem, I noticed that all four ethernet ports on the back were blinking yellow. I tried a variety of different things. I’ve powered it down and power it back on again same thing happens. I’ve powered down and power back on again without anything connected to it, such as the co-axle or any ethernet cables. Same thing happens after it restarts about three or four maybe five minutes it starts blinking again. it starts blinking again. I’ve tried wiring it directly to my computer without anything else and try to use the administration futures to see if I can get into the box or the modem and I can’t. It seems like. has anybody ever had a problem with these four blinking ethernet ports and is there anything I can do to stop it from happening? I have done the reset multiple times and nothing seems to work. I’m stuck there and I believe that that’s the cause of me not b

Cannot add devices on parental control

When I go to Arris Surfboard in the router (SBG8300 btw), I go to parental controls to manage devices, all I get is the option to manage devices (which is enabled) or access type (which is set to allow all) and even when switching these, I still get no option to add and manage a device. Its also keeps giving me bad certificates when using Chrome, Firefox, or Edge where it gives me a risk warning when going to 192.168.0.1 and each one tells me my browser is out of date and not compatible, I dont know if this is the issue causing features to not work or not, but firmware and browsers are all updated. any solution?
