    Resolved my problem. The culprit was a faulty phone on the system that was causing the NBX to react in the description above. Went around to each phone and unplugged for 10 sec and plugged back.

There is most likely another device on the network with the same IP as the phone system. You can check this by un plugging the link to the phone system (after hours of course) and then pinging the IP of the phone system. If you get a reply while the link is disconnected then you know there is a duplicate IP on the network. You can use your server to try to identify the device or use a IP scanner like NetScanTools to ID it. You could also try changing the IP address of the phone system and see if you have the same problem.

You can use Hotspot Shield to access blocked Facebook. It hides your original IP address by assigning a virtual IP address to you and you can bypass all web filters. Also It is free and easy to use.

make sure you have an ip address on the printer and that the lan speed is correct, from a command prompt you should be able to ping the printer.

Cannot communicate with our KM4850-W via the web interface. I can ping the device, I can print to it via IP, but I cannot access it via a web browser.


Hello,

Can you provide me with some more information we need to know to fully understand and fix your problem.

What Operating System are you on, what browser and what version are you using to connect to the web interface?

Does your IP enabled network printer connect into the system via a router or a switch.

What is the address you receive when you ping the printer? I know that may seem superfluous, but it will tell me what type of Network you are on.

And, just to verify the product you selected using our category selector you are attempting to connect with a Kyocera KM-4850-W, is this correct?

Thanks for your patience with what has to seem like ridiculous questions, but accuracy in understanding what and which printer we are talking about is more than just helpful, it will prevent misunderstandings and get you a complete answer sooner.

Thanks,
Worldvet

Zoom X5 adsl with Embarq high speed internet


Hello wil31nc, Lets get back to basics, what I want you to do is to turn off your windows firewall for now, reset your router/firewall to its default configuration. How to do this This can be found in your users guide (Hard Reset). Once this is done then I want you to connect your DSL upto the Router and your PC to one of your LAN ports. It (the router) should give you an IP Address at this point, then I want you to use your web browser to log into the web UI of the device once there you will need your ISP provided login ID and password. choose PPPOE and after you input those (login and password) into the proper dialog box. then from your PC try to perform these tests: ping to the router 192.168.1.1 (ping 192.168.1.1) ping to the ISP gateway address (ping xxx.xxx.xxx.xxx) (xxx=The octets of the address of the ISP router) ping to a site on the internet (ping www.dslreports.com) you shouls at least be able to ping to the gateway (ISP router) of your ISP. I beleve that this will get you up and running
