The downloaded file is "corrupt", and thus it fails the "verification" process.

Download the firmware again, and compare the two files.

Or, use a different computer to download the firmware, and to do the firmware-update.

You need to download this: Driver Update Software and update your drivers. Best of luck... Regards, Micky

Depending on the mode the phone is in, it may be only a layer 2 device - meaning it just broadcasts at layer 2 to find the NBX and once discovered, uses layer 2 for all communication.

I would recommend starting with what is simple. Have you tried replacing the Ethernet patch cord that the phone is connected to? How about the curly cord between the phone and handset? Does the phone do the same thing if you connect it to a different port? Does a different phone do the same then when connected where this phone is connected?

Well I think the port is bad, I had one that did something similar to your problem. I got on the 3Com website and submitted and RMA request and they upgraded my with the newest model. But if yours is still in stock they will replace with the same type. That is what I would do. Hope this helps ya.

If you get a 'Limited connectivity" on you wirelessconnection on your laptop, it means that the wireless card on your laptopprobably did not get an IP address from the wireless router. To fix this problem, right click on the wireless icon on the Task bar and thenclick Repair.This will force the wireless router to issue a IP address to the wireless cardon the laptop.
