Question about 3Com 3C509B Etherlink III TPO (730902) Network Adapter

1 Answer

I have a ethernet connection between a NT-Windows- and a Dos Computer. Both of the computers are equipped with the 3com 3c509b cards. These Computers was 10 years running wthout any problem. After a longer shut down time the connection failed. If I power up the computers the green LED at the 3com cards is on. The LED at the 3com card fitted to the Dos Computer is on all the time. The Dos computer has a program for testing the 3com card and all the test passed. So I believe there is no any problem. The LED at the 3com card fitted to the NT computer is on only during the booting process. Before the Log on process of the NT computer the LED is switched off and will not switched on again. According the Manual of this machine I checked the data IP number and so on and cannot find a failure. I find this option for help so I hope I can get some help Many thanks in advance. Sorry for my bad English Best regards Rudi

I want to know how I can re-set my 3Com 3crwe955275 wireless access point to its default factory settings. Can anyone help?


1 Remove power from the Gateway. 2 Disconnect all your computers and the cable/DSL modem from the Gateway router. 3 Using a straight through Ethernet cable, connect the Ethernet Cable/DSL port on the rear of the Gateway to any one of the LAN ports. 4 Re-apply power to the Gateway. The Alert LED will flash as the Gateway starts up, and after approximately 30 seconds will start to flash more slowly (typically 2 seconds on, 2 seconds off). Once the Alert LED has started to flash slowly, remove power from the Gateway. 5 Remove the cable connecting the Cable/DSL port to the LAN port, and reconnect one of your computers to one of the Gateway LAN ports. 6 Re-apply power to the Gateway, and when the start-up sequence has completed, browse to: http://192.168.1.1 and run the configuration wizard. You may need to restart your computer before you attempt this. 7 When the configuration wizard has completed, you may reconnect your network as it was before

How to find your MAC address using MS-DOS


The MAC address is the physical address your computer's Ethernet card or network interface card (NIC) uses to identify itself to other computers and devices on your network. There are different ways to find your Ethernet card's MAC address, depending on what operating system and programs you have installed. Since most Windows-based computers have access to the MS-DOS command prompt, using DOS to find your MAC address is one standard way to do it.

There are a couple of different tools you can use in MS-DOS to find your MAC address. All of them requiring opening a command prompt window, which you can do by typing "cmd" into the Run bar on the Start menu (or in Windows Vista or 7, you can type it into the Search bar instead).

- Getmac

Getmac is a utility that is included on Windows Vista computers and on newer Windows XP systems. Typing "getmac" by itself on a command line will return the MAC addresses of any NICs that you have installed in your computer. (If you have an Ethernet NIC and a wireless NIC, for example, Getmac will list the MAC addresses for both of them.)

- Ipconfig

Ipconfig is a command that will display your IP address if you are currently connected to a network. However, by adding the "/all" switch to it, you can also see your MAC address, as well as many other configuration settings. Type "ipconfig /all" and look for the line labeled "Physical Address." If you have more than one NIC, the MAC address for each NIC will be displayed separately.

I would first get a new Ethernet cable and try it. If that doesn't fix it, call your cable company and have them do a diagnostic from their end. They can tell if it is their equipment or not. It their modem is OK, and the Ethernet cable is OK, then your LAN (Ethernet) card is either going bad, or possibly not completely inserted in the socket. To check: turn off and unplug your PC. Take the side off, look where the Ethernet cable goes into your computer. If it is on the motherboard, you may want to get a LAN card and use it instead of the onboard. If the cable goes into a card plugged into one of the slots, make sure it is fully inserted. If it is, you may want to get a new card.

Cisco access point


Hi,
How to configure wireless access point using a laptop
Wireless technology makes connecting to the Internet possible from anywhere within the range of the network. Unfortunately, not all Internet-capable devices have wireless technology, and many still require an Ethernet port connection. If you have a laptop with a wireless card and an Internet connection, you can make the laptop a wireless access point and share that connection with other devices, whether your laptop runs a Windows or OSX operating system. Windows computers allow other devices to access the wireless network via a physical connection to the laptop, while OSX computers allow AirPort equipped devices to connect as well, creating a second wireless bubble for the network.

Instruction:
WINDOWS
1 Turn on the laptop and the device with which you will share the connection. Ensure the laptop's wireless card is turned on and you have an Internet connection.

2 Connect an Ethernet cord to the port on the laptop, and the other end to the receiving device. You need to make the connection first, or you will not be able to access the sharing options for the connection.

3 Open the list of network connections on the computer. In Windows 7 and Vista, access this list by typing "Network Connections" into the Start menu search bar and pressing "Enter." In Windows XP, click on "Network Connections" in the Network and Sharing Center section of the Control Panel.

4 Right click on the wireless connection and select "Properties," then navigate to the Sharing tab. This tab will not appear unless both devices are connected.

5 Check the box marked "Allow other network users to connect through this computer's Internet connection." Click "OK" to save the changes.
OSX
1 Click on the Apple menu and select "System Preferences." Click the "Sharing" option, then choose "Internet Sharing."

2 Select the Airport and wireless network in the "Share your connection from:" drop-down menu.

3
Select an output format for the connection in the "To computers using:" drop-down menu. Choose "Ethernet" for a physical connection or "AirPort" for wireless broadcasting.

4
Turn on the device you wish to receive the connection. Connect the devices with an Ethernet cable, or turn on the receiving device's AirPort card and connect wirelessly.

Dell Inspiron ethernet card plug bad, either send tower to Dell for 3 weeks or replace and bypass with new ethernet card PCI, any problems with doing this?


There should not be any problem with you buying your own PCI ethernet card and install it yourself. They are not that expensive. www.newegg.com has on for only $7.99 and it will work fine in your computer. It does not need to be from Dell.

Want to connect Linksys Wireless-G Broadband Router WRT54G to my computer for internet access.


I don't understand your question.

You connect to a router either wirelessly or via ethernet or via USB. There is another piece you need, you need a connection, DSL, FIOS or Cable. Do you have a modem?

If you have a moden, you connect your router to the modem by the method of your choice (Ethernete or USB or wireless). Then you connect your computer to your router via the method of your choice. I presume you have more than one cocmputer? You dont really need a router UNLESS you cannot put your computer near your router AND/OR you have multiple computers you want to network to your connection.

Sometehing else, is your computer equipped for wireless? or do you have a ethernet card called a NIC (Network Interface Card) and your operating system ... is it wireless able?

Does this help any?
