I can't seem to get to the 7760 POE to configure it. It does not show up in the Wireless Infrastructure Device Manager. So I tried connecting to it through a null modem cable to my serial port (configured correctly as per manual instructions) using HyperTerm, and still no go. Even set it back to factory settings. Any thoughts

The short answer: No

The long answer: You will need a device that will handle call control. That can be an ISR router (gen2 example: Cisco 1900, 2900, or 3900 series) that runs Call Manager Express, or a Cisco UC5XX Box (or even full blown CUCM, though you will still need an ISR to get out to the PSTN). The switch will work great for the infrastructure side of things though. It is capable of layer 3 routing, voice VLANs, QoS, and PoE. But you WILL need something for call control.

plz check your wirless device is it faulty

Try reset the device and start a new configuration.It seems that your networwork have issues between the router and the powerlines.All need to be in the same network as per router configuration.Connect one adapter to your router and plug it into an available electrical outlet. Plug the second adpter into an available wall outlet and connect the other end to any device with an available Ethernet port such as a gaming console, set-top box, or computer.

pd: OS to use the adapters; Windows 2000, XP or Vista.

Question: What is infrastructure mode in wireless networking? Answer: Infrastructure mode wireless networking bridges (joins) a wireless network to a wired Ethernet network. Infrastructure mode wireless also supports central connection points for WLAN clients. A wireless access point (AP) is required for infrastructure mode wireless networking. To join the WLAN, the AP and all wireless clients must be configured to use the same SSID. The AP is then cabled to the wired network to allow wireless clients access to, for example, Internet connections or printers. Additional APs can be added to the WLAN to increase the reach of the infrastructure and support any number of wireless clients. Compared to the alternative, ad-hoc wireless networks, infrastructure mode networks offer the advantage of scalability, centralized security management and improved reach. The disadvantage of infrastructure wireless networks is simply the additional cost to purchase AP hardware. Note that home wireless routers all feature a built-in AP to support infrastructure mode.

In Vista, you can either go to control panel, device manager and right click on it and click "eneble"
or go to control panel > network sharing and set up wireless network connection
or
go to task manager (press and hold ctrl . alt . delete for a couple of seconds), until task manager comes up. Then click on the services tab, scroll down till you see "Plug Play or Plug and Play and make sure it's running. If it's not, right click on it then click "enable"

In XP
Open Network Connections
Right-click Wireless Network Connection, and then click Properties.
On the Wireless Networks tab, do one of the following: •
To enable automatic wireless network configuration, select the Use Windows to configure my wireless network settings check box. This check box is selected by default. For information about what happens when you enable automatic wireless network configuration, see Notes.
To disable automatic wireless network configuration, clear the Use Windows to configure my wireless network settings check box.
To connect to an existing wireless network, do one of the following:
Access point (infrastructure)
To connect to an existing access point (infrastructure) network, under Available networks, click the network name, and then click Configure.
In Wireless Network Properties, specify the wireless network key (Wired Equivalent Privacy) settings, or, if the network key is automatically provided for you (for example, the key is stored on the wireless network adapter given to you by your administrator), select the The key is provided for me automatically check box. If you are unsure about whether a network key is needed or which settings you need to enter, contact your network administrator or the wireless network adapter manufacturer.

Important
If a network does not broadcast its network name, it will not appear under Available networks. To connect to an access point (infrastructure) network that you know is available but that does not appear under Available networks, under Preferred networks, click Add. In Wireless Network Properties, specify the network name (Service Set Identifier) and, if needed, the wireless network key settings.


Computer-to-computer (ad hoc)
To connect to an existing computer-to-computer (ad hoc) network, under Available networks, click the network name, and then click Configure.
In Wireless Network Properties, specify the wireless network key (Wired Equivalent Privacy) settings, or, if the network key is automatically provided for you (for example, the key is stored on the wireless network adapter given to you by your administrator), select the The key is provided for me automatically check box. If you are unsure about whether a network key is needed or which settings you need to enter, contact your network administrator or the wireless network adapter manufacturer.
If you want to connect to a computer-to-computer (ad hoc) network and both computer-to-computer and access point (infrastructure) networks are within range of your computer, click Advanced, and then click Computer-to-computer (ad hoc) networks only.
To configure a new wireless network connection, click Add, and then do the following: •
In Wireless Network Properties, specify the network name (Service Set Identifier) and, if needed, the wireless network key settings.
If the network connection that you are configuring is to a computer-to-computer (ad hoc) network, select the This is a computer-to-computer (ad hoc) network; wireless access points are not used check box.
To change the order in which connection attempts to preferred networks are made, under Preferred networks, click the wireless network that you want to move to a new position on the list, and then click Move up or Move down.
To change the wireless network connection settings for a network that is listed in Preferred networks, click the wireless network for which you want to change settings, click Properties, and then change the settings as needed.
To remove a wireless network from the list of preferred networks, under Preferred networks, click the wireless network that you want to remove, and then click Remove.
To update the list of available networks that are within range of your computer, click Refresh.
To automatically connect to available networks that do not appear in the Preferred networks list, click Advanced, and then select the Automatically connect to non-preferred networks check box.

Hope this helps

Infrastructure mode just means that you're connecting to a router as opposed to a computer to computer connection (or device-computer/device). Since it is a router it doesn't have ad-hoc and infrastructure modes.

What exactly are you trying to do? If you want to connect a pc/device to your network, then just find the network and connect, you'll be in infrastructure mode.

i used a different site as you did not post my problem!

do you have built in wireless or plug n play wireless.
if you have plug n play wireless and it isnt plugged in(connected)
it wont show in device manager if its built in you should at least see wireless icon.
if you downloaded the driver from site its a self extracting file that unpacks the software to install it doesnt install in other words you need to locate the extracted file and execute it which will install the driver then pc will detect device and install to system.
also try installing wifi manager and use without zero config.

that's because your windows wireless is most likely conflicting with the actual wireless device manager..only one can do the job..

I have NO EXPERIENCE with this equipment; but have researched this to some degree on the internet. If you are willing to experiment with me we may both learn something. First thing I learned is the difference between ad hoc and infrastructure networks. I have a feeling the default for most wireless routers and wireless adapters is an infrastructure approach. From reading the EEOC-3220 documentation its default is called bridge mode which is an ad hoc network. (this would seem to require reconfiguring your wireless adapter whenever you move from indoors to outdoors -- not desirable.) This can be changed to an infrastructure network by configuring it as an access point which also appears to allow configuration of additional security options including WEP or WPA encryption and MAC checking and could allow hiding the SSID if desired -- all of which apparently could and should match your indoor wireless router. The preferable configuration for the EOC-3220 would be to set an IP address statically (dynamic may be possible) to one valid for the indoor wireless routers subnet and not already used in your indoor wireless router's subnet and disable DHCP on the EOC-3220 and allow your indoor network to control DHCP for the outdoor segment. From what I can tell this configuration should allow the two wireless devices to attach to your PC in a seamless or transparent manner.
