Question about Netopia (3347NWG-VGX) Wireless Router (3347NWGVGX)

Netopia losses connection to internet and to server and vp phones

I am a small business using a file server with Windows Business Server 2003. My internet provider (AT&T) recently replaced my old Cayman router with a Netopia 3347-02. Since then we have had nothing but problems. My tech support people tried unsuccessfully to change the ip address of the Netopia router to the ip address of the old cayman router, but each time they tried, the router would freeze and would require a hard boot (back to the factory settings) to restart it. AT&T finally convinced my IT people that the ip address could not be changed in the router and so we changed the ip address in the server and most of my software. For the most part we are up and running, but when we plug in my Toshiba VP phones, the internet goes down within about 5 minutes and can only be restarted by unplugging the vp phones and doing a soft re-boot on the router. Toshiba says their VP phones do not require an ip address to be programmed into the phones, so apparently that is not the problem. Also, about twice a week all the desktop computers lose connection to the internet and/or the file server. If we lose connection to the internet and file server at the same time, we can do a soft reboot of the router and get restarted, but shortly thereafter, we lose connection to just the file server and have to reboot it. I have had 4 different tech people from 3 different companies try to diagnoise my problems and every one of them have told me that this Netopia router is not designed for a business setting. AT&T does not agree. Can you help me?

    Thank you for your help. My tech was very doubtful abou the DHCP conflict, but it turns out you were right. He resolved the DHCP conflict and now we can plug the phones in without it taking down the internet, however, the phones still do not operate and the display screen says "searching for IPU". They are Toshiba IP Enterprise phones - model IP2010-SD. Both our static IP address and the address of our router have changed since the phones last worked. Do you have any additional suggestions?

The Netopia Is a business-class router. Not clear from you question are you running Small Business Server or Windows Server 2003? If its the former, it has a wizard that will configure your LAN & the Netopia.
You can configure the Local IPs on the Netopia in the DHCP settings in expert mode.
The VP (VOIP?) phones are acting as a DHCP server & re-configure the network to their defaults.
Any 1/2 decent IT person (witth some real qualifications) could figure straiten this out...beware of "Techs"

You can change the IP of the router via the GI going in through expert mode and configeration. You can also telnet in, then enter the keyword "magic" then configure. You should get top>>. type "view" and you can step through all the setting, To change a setting step down through the tree by "keyword name"<CR>. until you get to correct keyword level, then to switch an option on/off "set on" or off or "set some-value", then save, then quit or top tio get back to top level of config tree. Known problem is that the target SNR for the down stream direction is set to zero [type in dmt ds tsnr to display this]. Looks like this modum is poorly implimented as it fails to down the speed if SNR drops below 6dB, I replaced it foe D-link DSL-3640B due to these performance problems. The 3640B gets hot but it keeps the SNR above 4 dB from 6500 kbps down to 4000kbps at night and back up next day. (dja.)

Why does it say communication error when i try to activate microsoft office 2007

This issue may occur if you configure your Internet connection to use a proxy server that requires authentication. In some situations, the Activation Wizard can not connect through the proxy server to an internal Microsoft server and show error message.

Alternatively, this issue may occur if your firewall software is blocking the attempt to connect to the server through your Internet connection.

To resolve this issue configure the firewall software to let the Activation Wizard connect to the Microsoft server or restart the computer in Windows Safe Mode With Networking, and then try to activate the software.

Hi My server has 8 memory slots but only 4 seem to be working. How can I make all of them work

It depends on the version of Server OS you have. If you already have 4 GB of memory installed and you're using Small Business Server 2003 or another 32-bit Server OS, then that is all the memory you'll be able to use. In order to use the other slots, you'll need to upgrade to a 64-bit OS. (Full Windows Server 2003 64 bit or later).

Cannot login to configure Belkin SMB KVM-over-IP swith

This happened to me until I installed the activeX control. Were you prompted for that, and did it install successfully?

After the activeX installed, did it also prompt you to install the secure certificate to access the site without IE prompting about invalid certificates?

Since you've tried multiple machines, I doubt security settings on IE are causing the problem. But my switch did these two actions before I was able to login successfully.
