SBG8300 Static IP Addresses LAN devices

While this modem seems to work, it does not work well at all! Contacting a human to discuss isn’t available it doesn’t seem without paying for it during the warranty period.  (ITS still under warranty!)Several issues I have.   The one that is driving me absolutely crazy is after I set the STATIC IP’s for devices on my network that MUST stay at a static location (CAMERAS).  I set up all of my static IP’s and turn on the network for them all to get their proper IP’s.  That seems to work well.  After a couple months, ALL of my static leases are GONE!  Cameras are at other IP’s.  Set to static again and again month or so later… GONE!  Other issues that I have had and I just STOPPED attempting to use it… I want my LOCAL IP’s to be 10.199.30.XXX.  I setup the DHCP server side for that with starting IP’s at the 20’s to 250.  Works GREAT… UNTIL… A month or so, the SUBNET changes to something that is WAY out of scope and NOTHING works.   I have to factory reset and start from scratch.  So I sto

Arris Surfboard SBG8300 2Ghz connection issue

Every time I need to connect a home device to the 2G connection it is a frustrating experience.  Most of the time I have to keep trying over a period of days and then finally it connects  -- and thankfully -- stays connected and reconnects following power outages just fine.  BUT I can’t go on like this having to repeat this process when a device needs to be reset.Here’s what I have discovered with my Orbit Sprinkler Control WIFI Hub:Connecting to 2G band, on entering Surfboard WIFI information, app just spins forever.  Never connects.Enable Hotspot on my phone, on entering WIFI information, app connects immediately. Enable guest network on Surfboard, on entering WIFI information, app just spins forever.Enable guest network on Surfboard, on entering WIFI information with on-purpose bad password, connection refused in a couple seconds.Enable guest network on Surfboard, disable authentication completely, on entering WIFI information app connects immediately.So … what’s the problem with th

surfboard SBG8300 - Lag Spikes

I got this modem router ~60 days ago (of course past my return time) and have recently ran into what seems like bottlenecking/spikes in ping randomly while gaming/streaming.  I originally thought this issue was just my pc but then my devices connected via Wi-Fi also had buffering hiccups This didn’t start until yesterday. Unplugged and replugged everything. Contacted ISP, everything was good on their end. Deleted temp files..etc…etc. only not new part of the hardware is my 30ft cable wire. However, it was working fine with my previous modem router and internet speed. when I test the speed I’m at expected levels. But again, it’s random when it happens and it’s across multiple devices. has anyone ran into this? Any help is welcome

Provisioned SBG8300 active, but "no" internet

Alright, here’s the deal:  I had recent cabline line with 90VAC on the line - yep, shocked at one point, so I checked.  My original modem was squealing, assumed it was dead.  Neighbors had internet.  Modem was an older Cisco DPC3010, so nearly a decade old, but still fast enough for me.  Assuming the dead original modem, not aware of the voltage on the line, I went and bought another modem so I could finish my work projects that were past due.  Plug new modem in instantly squeals at me and all lights solid - no change since then.  This was not the SBG8300 model.  So now two dead modems.  I’m an electrical engineer doing power system and control system designs. At one point earlier in career I was going for my Cisco CCNA; I decided to change careers and didn’t need to continue certification, but am not a complete novice when it comes to IT type stuff.Several calls with xfinity, and they have tech come out and see voltage, works on line, and requests new line be buried and to have other

SBG8300 "WAN over Ethernet?"

I just noticed my new SBG8300 has a setting on Ethernet port 4 to turn on “WAN over Ethernet.”  Does this mean I could connect this to a second router (elsewhere in the house) and connect to it as a separate network with internet connection?

Intermittent / no connection

I bought an 8300 so I could turn in our Comcast rental wifi modem. I selected the 8300 in part because it advertised the highest square foot coverage. We have a basic Xfinity plan - 75 Mb, and that has always been plenty (It was plenty for us at 25 and 50, back in the days when those were the basic plan data rates)The 8300 has so far been much less reliable, especially for my older Win7 laptop, which won’t connect at all despite 3 bars and 30 foot distance - almost line of sight location...my laptop connects only to our extender for the kids rooms down a hall, and that only intermittently. Out of curiosity I tried configuring the 8300’s guest network for 2.4G - still no joy.I turned on WiFi band steering and that somewhat helped, allowing me to connect but still only via the extender.Ideas anyone?
