Question about 3Com Wireless LAN Access Point 7250 802.11g/b (3crwe725075a-uk)

1 Answer

Frequent wireless disconnections 802.1X WPA TKIP

We have implemented 3com wireless access points in our network using 802.1X WPA TKIP settings. Windows IAS server is providing the authentication service for the wireless stations; the IAS server is integrated with windows active directory. Furthermore, the wireless stations get the IP from a centralized DHCP server. So far all is working fine. The problem is that Sometimes the wireless stations get authenticated and got the IP from the DHCP server but again disconnected and then start the process again and again. Sometimes the user is successfully authenticated and got the IP but when it disconnect from the wireless it fails to connect again We have setup the access points at different locations in a city. A user successfully authenticated in one location failed to get connected when roam to a different location. Note that all the IAS DHCP and Windows active directory are centralized. Furthermore we the wireless users have verity of laptops like DELL, IBM, Toshiba, HP. Kindly advise.

Try using predefined IP addresses. Let each pc make it's own IP address and see if the conflicts continue, if they do, post again. :)

I want to know how i can make my Linksys Router WRT160N work as access point


By default Linksys router behaves as Access point. On some router you have to enable the wireless function.

So the following to configure the router Wireless Access Point

Click the below link

Now it will ask for username and password

Enter username = ( blank) and password = admin
If you can't login using this credentials then you will have to reset the router

If you logged in . Then click on Wireless > Wireless security

On this screen select

Security Mode : WPA Personal
WPA Algorithm : TKIP
WPA shard Key : "enter a password here"
Group Key Renewal : set to default

Click on save settings. After that restart router .
Now your wireless network is secured and you will have to type the WPA shared key inorder to connect to router when it prompts. You can connect as many devices as you wish since it is a access point


Vote me If it helps

What's the difference between WEP and WPA? What should I pick?

WEP is a weak securtiy protocol that is outdated and can be easily broken

WPA is a newer security protocol that is much harder to break with AES encryption

WPA is always recommended mode for operation over WEP.

Use WPA2 which is latest version if it is supported by device.

My Sony vaio has limited access to Internet but all my family's computers working are fine, help

Make sure your connecting to the right network and check if the security type (WEP,WPA,WPA-PSK) and Encryption type (TKIP,AES) setting were the same with the other computers, you can also check the setting on the router to make sure :)

What is a wpa key password

WPA is a type of security for a wirelss router to keep people out of the network without the key password. The password is used to log onto the router and allow the computer to communicate with the router and internet. The key is created using the wireless router settings menu and can be found on the same menu. If you do not know the key then you will need to hook the computer directly up to the router and use the router settings menu to find out what the key is.

I have plugged in a wireless adapter for the 360 but...

A red steady light on the adapter means it is ready to be connected to a wireless network. If it fails to connect then the WPA key is not correct.

WPA automatically changes keys on a frequent basis for security purposes. So you need to take note of the SSID (wireless network name) and the Wireless security settings (WPA and passphrase) from the wireless access point/router.

Once you have the wireless network settings on the access-point/router, go to the System area to enter those settings.

If all settings are correct, exit the System area. Your console should now be connected to your wireless network.

Hope this helps! Good luck!

Security connectivity issues

is the PC connection you're able to maintain once upgraded to WPA a PC that is physically connected to the router? if so, that would make sense because WPA (and WEP for that matter) are only wireless security protocols and have no protections for hard-wired connections.

In order to convert your system to WPA security, you must first make sure all of your hardware is WPA compatible (that isWPA Drivers are available for it).

For your PC wireless connection, if you're running Windows XP you can go to the microsoft website and download the WPA client. It is available in the Microsoft Knowledge Base Article 815485. install the update and reboot. you will then be able to enable WPA security on your client.

Then you'll possibly need to update the drivers for your hardware for WPA support (router, wireless NIC, etc) if they did not already come enabled.

next you get to configure the router for WPA. you'll want to make sure you're set to WPA with preshared keys (no authentication server required), use TKIP as the algorhythm, and leave group key renewal at it's default value. and of course Select a key that is not likely to be guessed. write the key down as you'll need to configure your NIC using it.

to configure your NIC, once you're in the configuration menu select WPA-PSK for your authentication, TKIP for the encryption mode, in data encryption set it to TKIP, and in the network key put the key you selected earlier.

At this point you should be able to access your wireless router (or other access point). These instructions were kind of generic since i do not have the specific router you're using available to me, but the settings i discussed should be pretty universal when it comes to WPA security.

Encryption on/off

First you must choose a common encryption strategy for your home network. (Yes I am assuming Home Network)

In most consumer routers you activate encryption on the wireless services of the router. After doing so you must also actiate encryption services on the wireless adapters that communicate with the wireless router. The names of the encryption services in the wireless router and wireless adapter are WPA and WEP. It is important to assure all wireless adapters to connect to the wireless router can handle the encryption chosen because the router will only perform one. There are options within each technique such as the number of bits of the keys -- the longer the better but only as long as the shortest device can support. WPA is preferable to WEP because it was designed to correct weaknesses in the WEP standard and implementation. However if there is even a single device to be connected that cannot do WPA you must do WEP or replace the device WPA in home systems often have a couple of other attribute being WPA-PSK and algorithm of TKIP -- which again every wireless adapter and the wireless router/access point must support.

To procede further in a sane manner you need to identify all wireless devices that will participate in your wireless network and determine their capablities for encryption. This is generally done searching manufacturer websites under support looking for user guides and firmware updates. Sometimes a devices capabilities in the manual require firmware updates to be true for the device. Once that is figured out the standards for your network can be set and the actual implementation can proceed. You will probably want a working wired computer to maintain access to the outside world for assistance if anything goes wrong. You also want to track your changes and know how to back things out incase things become too difficult.

If you have any additional questions or would like to a review of your plan or assistance determining a plan gather up the appropriate manufacturer's names and models and I will assist as time permits.

I hope this helps.
