HT812 not connecting to Internet


#1

My HT812 VOIP Adapter does not connect to Internet. With a verified connection, the blue Internet light flashes on-off. I get a dial tone, but no calls in or out. I did a ‘reset’, but it is still the same. Thanks for any ideas and suggestions.


#2

Post the settings of the device.


#3

Hi Ipneblett, I have cut-copied-pasted the entire settings for Status, Basic Settings, Advanced Settings, Profile 1, Profile 2, and FXS Ports. Let me know what is relevant, and I can post them. Thank you, Bill.


#4

The profile and the FXS settings. You can mask any sensitive IP info. What are you trying to connect the HT to?


#5

I connect the HT812 to the Internet via short LAN cable to my 8-port router. Output is connected to a telco patch panel for analog phones.
Note: The HT812 blue Internet light will flash on-off whether connected to the router, or directly to the CATV modem.

From the above, it does not appear that you have done anything other than connect the device to an Ethernet cable. If this is true, then you need to obtain the manual and then program the device accordingly. You can start by connecting an analog phone to one of the FXS ports and then pressing “***” (three *) and listening to the prompts. There are two that you will need to listen to explicitly - the IP address and the WAN access settings. You can advance thru the prompts by pressing *. When you get to the WAN prompt, press 9 and then when it indicates “enabled”, you can reboot the device and then access it to program. Then, using the manual, you can program it.

Thank you, Ipneblett. I had purchased and installed this early August 2017. Programmed it then, and was working ok until recently. Seemed as it stopped recognizing the Internet connection (flashing instead of solid blue light). I eventually did a Master Reset with the rear panel reset, which would now read the original factory defaults as you noticed. With the unit still not recognizing a valid Internet connection (flashing blue light), I get the following through the IVR: IP 0.0.0.0 / WAN 00.0B.82.A2.B0.F4 / SUBNET 0.0.0.0 / GATEWAY 0.0.0.0 / DNS SERVER 0.0.0.0 It seems that I can do little with this until I can get it to recognize the Internet connection.

Two thoughts:

  1. You might check via the telephone interface that DHCP is turned on.

  2. You might try manually setting a local IP address & subnet via the telephone interface and then use the Web GUI to see what’s what.
