hard wired tv buffers

SBG8300 modem provider speed is 350, pay for 300 I have a hard wired tv that keeps randomly buffering, it doesn’t matter which app I am using on a Hisense Roku tv. I cannot log on to the gui interface because every time I try to log on the password automatically doubles in size when I hit the log in button, happens on desktop and iPhone.

"Connected, No Internet" - ARRIS SURFboard SBG8300

ARRIS SURFboard SBG8300 DOCSIS 3.1 Gigabit Cable Modem & AC2350 Wi-Fi Router Purchased this modem/router combo last month so that I could stop renting one through Midcontinent. The issue below has occurred intermittently since then, but worse over the last 2 weeks. I am not well-versed in this area, but will explain the best I can. I receive an error - every day - of "Connected, No Internet" on my Hisense android TV. Other devices (phone, laptop) will also disconnect when this happens. I've rebooted the modem (and affected devices) multiple times. My TV network settings will show "Connected - Signal Strength Excellent" but no wifi access. When I reboot the modem, I'm able to reconnect the other devices, but the TV will usually continue showing the error. (As of the time of this post, the TV is connected to wifi and working). I have a DVR security system connected to the modem via ethernet cable, which is unaffected by this connectivity issue. My current service is Midco Internet 500: u

Surfboard SGB8300 Firmware updated and slow speed

New modem/router. Subscribed to Spectrum 1G internet. Speeds slow - 30-90 Mbps with cable, about the same over Wi-Fi. Called spectrum, tech came out and suspects device needs a firmware update. Speeds were good out the cable - 800-900Mbps. When installing, I remember the blue/green flashing. Tech was kind enough to look in to it a little bit, but we can’t tell if the firmware on the device is most current. In the manager, it shows firmware 01.01.139.NCS installed. Is that the most current? any other advice would be appreciated.

Problem connecting devices to SBG8300

I am totally not technology savvy. My problem is connecting 3 mini Blink cameras and 2 older laptops to the SBG8300. I reset the mini Blinks and they won’t recognize the 8300 unless I unplug the router for 10 seconds. Then they may or may not recognize it, and when they do I enter the wifi password. Then they disconnect a few minutes later. Same with the older laptops. I have 2 laptops, 2 phones, and smart TV that have successfully connected without problems. Any idea’s why these camera’s and older laptops don’t connect. The problem started immediately after setting up the 8300. Hopefully this makes sense.

SBG8300 internal time is floating around - How do I perminantly set it?

I can’t seem to lock the router time and it floats intermittently. I don’t know if there is a problem tracking time or it’s getting set by 1 of the 3 included Time Servers incorrectly. Setting Automatic vs Manual seems to have no effect. Just bought a SBG8300 and it works great with exception of Parental Control and blocking timeframes for different devices. Behavior is intermittent and unexpected of when a block happens. After some trouble shooting, I noticed the time display if floating all over the place. Sometimes 10 hours ahead, sometimes 8 or something. Once I hit the “Save Time Settings” button, it snaps back to the correct time I’m in (Pacific Time), but if log out and log back in 20 minutes later, it may or may not be off. User Steps: > Admin page https://192.168.0.1 > Gateway > Summary > Time (page is https://192.168.0.1/time.php) > Observe: “Router Time” value. Time Servers: clock.via.net ntp.nasa.gov tick.ucla.edu

login to surfboard web manager

I set up my email and password on my Arris surfboard gateway and i can login via the 192.168.0.1 IP address but when i use the same email and password for the surfboard web manager it responds with incorrect credentials and won’t allow me to login. I don’t understand this as they are supposed to use the same login info. Why does the surfboard app not let me login?

No solid lights on start up

I’ve had a lot of issues with my internet since I moved into my apartment. Finally someone at Comcast told me my modem was incompatible with my speed so I bought an SBH8300. I’m trying to set up the modem and the lights are constantly flashing. The internet light blue and the wifi light green. They were both solid green like the manual says they should be for just a second and then started flashing again. I’ve tried contacting Xfinity but they’ve been useless and apparently arris doesn’t have a customer service line anyone can call. So I am here. Help me.

Can't access Admin Portal!

Unable to login in with default admin username and password. Keep getting Invalid user name or password, or your access has been locked due to multiple failed login attempts! I can admit, i went in a changed the names and passwords for the network and saved changes before changing the admin login credentials. Also, the router came with 4 connection options (2 standard and 2 5G- one for home and guest each). However, the site only allowed ne the option to change two and the other two are still available with the default names and default password. Any suggestions to access and manage my router through the admin portal?

SBG8300

SBG8300 was dropping internet a few times per day. Did a hard reset with button on back. Signed on to Surfboard access on web and it asked to set a new wifi password. I was able to setup all devices successfully and now it will not allow me to access the modem via web. admin password does not work, my old user and pass does not work and nor does the wifi password I setup work with user admin or my old user name. How to I access ?

Blocked VPN Access To Firewalled Addresses

I have changed nothing on my SBG8300 to have caused this problem. For several years I have used this home modem to connect to my company VPN and then log into my company's factory firewalls to access their network(s). I have been using the company issued Cisco AnyConnect VPN software. For the past month, when working from home, I am not able to access the firewalls and the browser reports that the address cannot be found. On infrequent occasion I have connected to a firewall but there is no rhyme or reason for why it worked. Restarting the modem does not help. My internet provider (Xfinity) tech support remotely examined it and didn’t know what the problem was so she suggested I get a new one (LOL, she gave up). I can access the firewalls using my cell phone hotspot or another location that provides internet, but not through my modem. At one point today I tried disabling the modem internal firewall but that did not help. When I re-enabled the modem firewall and restarted the modem, the

Unable to connect SBG8300 to WOW

I am unable to connect the SBG8300 to the WOW network. I am connecting through the same coaxial port that my current WOW rented modem is connected to as I type this. While on the line with WOW, they said they could not find it via the HFC MAC. The lights on the modem were green and I do not have any splitters or anything complicated connected to this line. Has anyone encountered this or been able to get this router working with WOW?
