EOC-3220 connects but no internet access

I am using an EOC-3220 EXT in bridge/client mode for long range wifi access from my boat.
I am able to connect to an access point using manually assigned IP addresses for my PC and for the EOC-3220 in bridge client mode.  I have access to the EOC-3220 using IE browser.
However, I have been having trouble accessing the internet from my PC after connecting the EOC-3220. I had access to the internet through my PC's browser briefly after changing my PC from a manually assigned IP (  to automatically retrieve an IP address. Now I cannot access the internet with the PC's browser with either a manually assigned IP address of or by allowing the PC IP address to be automatically assigned.
I have the latest firmware upgrade installed (1.40….). Can you tell me what I am doing wrong?

Re: EOC-3220 connects but no internet access

What are you using for Internet connects? do you have the Access point connected to a Router. or is it connected to the Cable or DSL modem. I will need more information to complete this. If you have a router is is set to give an IP address or do you have a static IP? If it is set to give a Dynamic ip change the access point to recieve ip address from router and same with computer. If your connected directly to the Modem with the access point and you only have one IP address it will be used by the access point and not allow the computer to connect.
for more help please provide your internet (DSL, T1, CABLE) if you have router,  how it provides IP, and how access point is connected to it.

How to setup internet between 2 EnGenius EOC-2610 devices?

Thanks for a very thorough problem report. It's a little ambiguous near the end, though, so I will have to restate what I think I understand you are saying.
You are saying that you have your internet connection and AP in one building, and two devices or PCs in that building can access the internet and share files (though you don't specify if they are using the EOC-2610 access point or are just accessing the router in some other fashion). But you have a remote building where there is one PC and one EOC-2610 in Client Bridge mode, and although both EOC-2610 units seem to be communicating with each other, the PC will not communicate with anything. (I presume you have inspected the access point's configuration screens and verified that it does have the other EOC-2610 listed as a connected client.)
First, the PC in the remote building has to be connected to the Client Bridge EOC-2610 by its ethernet cable in order to access the network. Second, the PC in the remote building has to have a valid IP address in the range, or it won't communicate with anything. If you are relying on your router's DHCP to assign your PC an IP address, verify that this has happened by examining your PC network properties. If you are assigning all IP addresses manually, make sure you have assigned the PC an address, and one that doesn't duplicate some other device.
Sometimes failure to specify DNS servers appears to be a lack of communication with the network. Open a browser and type in the URL bar. If you get to, you have a good network connection. If you type in the URL bar and can't get the same result, you need to define DNS servers on the PC (or inside your router).

Problem using 2nd hand AP senao EOC3220 EXT

You can use this unit either as an access point, to provide wireless access to a network you already have, or as a bridge, to access a remote wireless network someone else has.
Note that you own the EXT model, meaning that you have to attach your own antenna to the connector before it will function. There is no internal antenna on this model.

Getting to setup pages

look at your DHCP client table on your router to find the IP address of the device.  You can identify if via the MAC address on the table (and sticker the 3220)

After a windy day lost wireless connection

For a new unit disconnect the eoc from the network and connect directly (through POE injector of course) to your laptop/pc.  then in network connections setup your lan port TCP/IP settings as follows.  ip subnet mask then gateway

point your browser to or (one if it is in AP mode and the other address works if it is in bridge mode).

When configuring, I assign it an new static IP outside of the DHCP assignment range.

To see how it is setup afterwords you can use hyperterminal with a null modem cable to view the current config.  instructions on the support page.

There no connection betwen my PC and eoc-322o

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.

AP Mode Problems

Probably you have to learn that there are various people looking for an access of the internet through your facilities. Anyway, inorder to solve your problem these are the following recommendation I made just for you. Hope this will be helpful.

1.) How do I reset the EOC-3220 / EOC-3220 EXT / EOC-3220+ back to factory default settings? An RS-232 null modem serial cable is required for this procedure.
(where to buy it :

1. Connect the EOC-3220 to your computer with a null modem serial cable.

2. Start a HyperTerminal session: Click Start and then select Programs -> Accessories -> Communications -> HyperTerminal.

3. After the HyperTerminal window appears:
a. Give this new connection a name. Ex: EOC-3220.
b. Select correct COM port. Ex:COM1.
c. Set baud rate as "38400", data bits "8", parity "none", stop bits "1", and flow control as "None". Then press “OK” to bring up the HyperTerminal window.

4. Wait until the "#" is displayed in the HyperTerminal window.

5. Type "flash reset", then hit enter.

6. Type "reboot", then hit enter. After the device reboots, all settings will be at factory default.

Phase II

1.) Since that you already reseted the AP you need to use the default IP which is user: admin password: admin

2.) Make it sure you need to use different IP such as and the subnet:

3.) The idea of configuration in come from your own desire which was no body can no longer try to match your network IP so that there will be no body access your AP anymore without your knowledge.

4.) You need to make you SSID invisible to everyone inorder no body no longer able to reach your SSID by setting up basic setting which is transparent to everyone.

5) And lastly change the default user and password of your AP.

Good Luck
