In most cases, the modem’s Status page can be accessed by browsing to the modem’s address 192.168.100.1 from a client connected to the Wi-Fi router or connected to the cable modem.

 

If you’re unable to get to the modem’s login screen, the workaround is to manually assign IP addresses in the device (Wi-Fi router or PC) that is directly connected to the modem.  

NOTE: The workaround requires knowledge of assigning IP addresses to the PC or Wi-Fi router.  Refer to the user manual for instructions.

 

Wi-Fi Client Only

If you only have a Wi-Fi client, the only workaround is to change the Wi-Fi router’s WAN IP address.      

  1. Log in to your Wi-Fi router’s settings page and navigate to the WAN or Internet settings. 
  2. Set the WAN IP address to Static and enter the following network addresses.
    • IP Address: 192.168.100.200
    • Subnet: 255.255.255.0
    • Default Gateway or Router: 192.168.100.1
    • DNS addresses are not needed to access the modem’s status page
  3. Save the WAN settings.
  4. Browse to 192.168.100.1 with the Wi-Fi client.

Don’t forget to change the Wi-Fi router’s WAN settings back to DHCP or obtain IP automatically.

 

Cable Models with multiple Ethernet Ports (SB8200, S33, T25)

If you have a PC that supports an Ethernet connection, you can use the following steps to access the modem’s Status page.

  1. Connect a PC to the 2nd Ethernet port of the SB8200, S33, or T25 modem.
    • If you don’t have another Ethernet cable, disconnect the Ethernet cable from the Wi-Fi router and connect it to the PC. 
  2. Disable the Wi-Fi in the PC so it only has one connection and that’s to the modem.
  3. Go to the PC’s Local Ethernet Adapter settings and enter the following network addresses.
    • IP Address: 192.168.100.200
    • Subnet: 255.255.255.0
    • Default Gateway or Router: 192.168.100.1
    • DNS addresses are not needed to access the modem’s status page
  4. Save the PC’s network settings
  5. Browse to 192.168.100.1 with the wired PC.

Don’t forget to change the Local Ethernet Adapter settings back to DHCP or obtain an IP automatically and enable the Wi-Fi in the PC.

 

Connect PC to Cable Modem

If you have a PC that supports an Ethernet connection and you’re unable to change the Wi-Fi router’s WAN IP address, your only option is to bypass the Wi-Fi router and connect the PC directly to the modem.

  1. Disconnect the Ethernet cable from the Wi-Fi router and connect it to the PC. 
  2. Turn off the Wi-Fi router so that the PC only has one connection and that’s to the modem.
  3. Go to the PC’s Local Ethernet Adapter settings and enter the following network addresses.
    • IP Address: 192.168.100.200
    • Subnet: 255.255.255.0
    • Default Gateway or Router: 192.168.100.1
    • DNS addresses are not needed to access the modem’s status page
  4. Save the PC’s network settings
  5. Browse to 192.168.100.1 with the wired PC.

Don’t forget to change the Local Ethernet Adapter settings back to DHCP or obtain an IP automatically and reconnect the Wi-Fi router.

When I see “work-around” that tells me “a temporary way of getting the job done until a permanent solution can be implemented.” Is a permanent solution for this problem in the works by Arris?

The root cause of the problem is that the software in these new modems requires an http client device to the in the same subnet as the modem (192.168.100.0/24) to access the web page. This requirement doesn’t exist for ICMP pings with these same modems. Those work regardless of the source IP subnet. With this design, it is extremely inconvenient for the customer to access their modem status pages.

Maybe Arris sees this as a security issue. I don’t see why this is a security issue now that the modem web pages are password protected.

This design is unacceptable to me. I’ve been an Arris fan for a long time and worked with some of the engineers from Motorola who designed the original Surfboard modems.

The cable modem status page can not be accessed.

The connection has timed out

The server at 192.168.100.1 is taking too long to respond.

I have a 2 Fold issue w accessing the modem web page…. First, it’s always saying PC this and PC that. I have an iMac, does that matter? More importantly, it says to disconnect your router to plug your ‘PC’ directly into the modem. If I unplug the router, how am I expected to access the internet for the web page?

Did you ever get an answer on your statement? What have you done w your modem?

So what is your thought? There is really no way to access the web page? 
Never had I had this much headache trying to access a modem or a router. It’s always been an easy process, where you can go into the page, and just make your selections as needed….
