How to Connect Two Computers Without a Router

Let’s assume you have two computers at home and you want to connect them together so that you can easily share an internet connection between the two machines or transfer photos, music and other files from one computer to another. How do you do this?

Connect Two Computers Directly

There are two options – you can either buy a router or, if you are looking for something more simple and don’t want to spend money on new networking hardware, you can connect the two computers using a commonly-available cable. The latter method doesn’t involve any complicated network settings and you will still be able to share files, internet connection, and even printers between computers.
Things you need:
To set up this basic wired home network, all you need is an inexpensive Ethernet crossover cable and the other requirement is that network cards* (also known as LAN or Ethernet cards) should be installed on each of you computers.
[*] This should not be an issue because network cards are available on most newer machines by default but if you are working with a very old computer, you can either attach an internal LAN card to your computer’s motherboard or go for a USB Network adapter that will turn a USB port into an Ethernet (RJ45) port.
An Ethernet crossover cable looks like a standard Ethernet cable but the internal wiring is a little different. You can purchase crossover cables at Amazon.com or from your local computer store. If you have trouble finding them, you can purchase an inexpensive crossover adaptor and that will let you use any standard Ethernet cable as a crossover cable.

Connect Computers with an Ethernet Crossover Cable

Before connecting the two computers with a physical cable, make sure that both machine are using the same workgroup*. Here is step-by-step guide that explains how you can change the workgroup of your computers.
Changing workgroup in Windows XP – From the Start menu, right-click “My Computer.” Select Properties in the drop-down menu, and then select the second tab that says “Computer Name” from the System Properties window. Now click the “Change…” button, enter a unique Workgroup name and reboot your computer.

Changing workgroup in Windows 7 or Vista – Open the Control Panel, type “Workgroup” in the search box, and select the entry that says “Change Workgroup Name.” Click the “Change…” button, enter a Workgroup name and restart the computer. Windows 7 users can skip one step; simply type “Workgroup” in the search box in the start menu, and select the first entry, then proceed as above.
Now that the workgroups are same for both computers, connect the two computers together using the Ethernet crossover cable. Simply plug-in one end of the crossover cable into the network adapter of Computer A and connect the other end of the cable to the network adapter of Computer B.
Windows will automatically recognize the new network, and you can now easily view files and folder that the other computer has shared. Simply open Networks from the Start Menu (or the Control Panel), and you should see the other computer by its name. You can then browse any shared files on the other computer, and can even utilize shared printers.
Troubleshooting – If you do not see the other computer under Networks, you probably have a prompt at the top of your Network window saying that Network discovery is turned off (screenshots below). Select “Turn on Network Discovery and File Sharing.” In the next prompt, select “No, make the network I am connected to a private network.” Now you should see the other computer on the home network.

While it is possible to share files between two computers connected with a crossover cable without making them part of the same workgroup, the method will only work if both computers have this network set as a private network, and may still cause problems. It is therefore advisable to have both computers on the same workgroup before sharing files and printers.

Share an Internet Connection Between Two Computers

There are scenarios where you may want to share the same internet connection between two computers. For instance:
Situation A - You have setup a Wi-Fi network at home but your old desktop computer doesn’t have a wireless network card. In that case, you can use the laptop to connect to the internet wirelessly and then share that same connection with the desktop over a crossover Ethernet cable.

Situation B – You have a netbook with a built-in cellular data connection. You can share that connection with any another computer at home through the crossover Ethernet cable.

Situation C – You use a (slow) Wireless USB modem with your laptop computer while your desktop is connected to an ADSL Broadband line and there’s no router at home. For any bandwidth intensive tasks, like when you want to backup photos from your laptop to an online service, you can connect the laptop to the desktop and things will happen much faster.
OK, let’s look at the steps required for sharing an Internet connection.
First, if you only wish to share internet connection and not files, both computers need not belong to the same workgroup. All you need to do is to connect the two computers with the Ethernet crossover cable, and then turn on Internet connection sharing in the computer that already has an Internet connection. The instructions vary for different versions of Windows:
For Windows XP – Select “Network and Internet Connections” from the Control Panel and click “Network Connections.”

Right-click on the network connection you wish to share (the one connected to the internet), select Properties, click on the “Advanced” tab, and then check the box that says “Allow other network users to connect through this computer’s Internet connection.” Click OK, and the second computer that you have connected to this computer with the Crossover Cable should have internet access now.

For Windows 7 and Vista – Open Control Panel, enter “network connections” in the search box on the top right and select “View Network Connections.”

Right-click on the network connection you wish to share (this must be the one connected to the internet) and select Properties. Select the “Sharing” tab and then check the option that says “Allow other network users to connect through this computer’s Internet connection.” Click OK, and the other computer you have connected to this Windows 7 or Vista computer should have internet access now.

Steps to IncreaseNetwork Browsing Speed

If you’ve ever browsed folders on a network, you’ll know how slow it can be. With a simple registry hack, you can increase your network browsing speed. Here’s how to do it:


  1. Click Start>Run and enter ‘regedit’.
  2. Navigate to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version/Explorer/RemoteComputer/NameSpace
  3. Locate the key named {D6277990-4C6A-11CF-8D87-00AA0060F5BF}. This key tells Windows to search for scheduled tasks, of which there are none. Right click on it and delete it.
  4. If you have no use for viewing remote shared printers and is only interested in shared files, consider deleting the printers key as follows: {2227A280-3AEA-1069-A2DE-08002B30309D}. This will further improve network browsing speed.

Your networking browsing speed should be now considerably faster, as it will have no delay.

How to Repair Safecom Router / Upgrade Firmware via USB

Firmware Upgrade:

Click here Download the new firmware and save it to your desktop. Unzip it. Locate the reset button which is on the back panel of the router. Hold the hidden reset switch with paper clip for 5 seconds with the router is on. After you release that switch wait for the ADSL LED to start flashing or becoming solid. Now click on file Run while the router is connected to to your computer through RJ45 cable or USB cable. When you click on Run a MS-DOS window will start so must wait until the DS-window disappear. You will find that some time this Dos window will stop its ok as it does take some time to upgrade the firmware. After the upgrade the MS-dos disappear then it mean the router is now upgraded. Now power off the Router and powered on. When you see the ADSL LED then simply go into the router,s smart setup page by typing 10.0.0.2 into the broswer, you will be prompted for router user name which is admin and password is epicrouter Now you will your find the smart setup page just insert your ISP User name and if password then password also. Then Click on the save and reboot Button. Wait 30 seconds for the router to be fully rebooted and now you should be online.

Do you need to upgrade the firmware ??? From the smart setup click on advance link and if you see Customer Software Version: safecom.cn 10-07-04 then do not upgrade the firmware. If not and your router is not stable or if you are having msn problem then upgrade it.


Router Repair:

After powering on, a correctly operating router will have the ADSL LED flashing continuously when the ADSL line cable (RJ11) is disconnected. When the ADSL line cable is connected to a line that has been activated for ADSL the ADSL LED should be on constantly. That said, on some revisions of PCB the ADSL LED will remain on constantly and flash once every 15 seconds or so.

If the ADSL LED does not come on after powering on the router then the likely scenario is that the on-board flash memory has become corrupt.

If this is the case you will have to carry out a USB firmware flash in order to fix it.

  • A PC with an Intel or VIA chipset and onboard USB port (other chipsets may not be compatible with the repair program) and FAT based file system (Not NTFS)
  • A Philips or plus screw driver to open the router
  • A USB cable (one was supplied with your router) to connect the router to the PC via the USB port
  • A jumper (like the ones used on hard drives or CD-ROMs to determine Master or Slave operation)
  • Make a note of the router’s MAC address. This is a unique number that identifies the router. You will need to enter this number when the prompted to do so by the repair program. An example would be 00064F15395A (it is a 12 digit hexadecimal number). Look for a barcode sticker on the underside of the case. You should also find a similar barcode sticker with the MAC address on the circuit board (see below)

Step 1: POWER OFF and open the router

  • Power off and unplug all the cables from your router. Turn the router upside down and place it on a flat surface. Carefully peel off the rubber feet to reveal the screws beneath. You might find it useful to stick them on the base of the router so you do not lose them. Undo the screws (usually four) and keep them in a safe place.
  • Turn the router the right way up and carefully remove the top cover by gently lifting it. The front panel may have a slight lip on it making it a little tricky but don’t use brute force.

STEP 2: Connect the jumper

  • You should discharge any static electricity stored in your body by touching something ‘earthed’ like a metal radiator or any metallic object/surface.
  • Locate the 2-pin link (the position on the board may vary but there is only one) on the circuit board. Carefully push the jumper onto the pins ensuring that both pins are covered and avoid touching any other parts of the circuit board. You may want to use tweezers.

Place the jumper here

  • Disconnect all USB devices from your PC including hubs

STEP 3: Flash the router

  • If your PC is off, power it on. Once it has finished booting put the Safecom router CD into the CD-ROM drive and browse for the firmware folder ‘SAMR-4110′. Copy this entire folder to your C: drive (We assume that you have a FAT file system and not NTFS since NTFS partitions cannot be seen with DOS and the repair program is DOS based)
  • Power off your PC and connect the USB cable to the USB port on the router and connect the other end of the cable to one of the USB ports on your PC (preferably one on the main board as USB ports on add-on cards may not be compatible with the repair program)
  • Power on the router and start your computer and select boot from CD-ROM in your BIOS setup. Save settings and reboot.
  • Make sure the Safecom router CD provided with router is still in the CD-ROM drive.
  • When prompted, select “Start Computer with CD-ROM support” to boot to DOS from CD.
  • At the command prompt change your default drive to C by typing “C:” and press the “Enter” key (do not include the “” when typing). Then change directory to the firmware folder you copied earlier by typing “cd SAMR-4110″ and press the “Enter” key.
  • You should now see that your command prompt has changed to the following:

    C: \SAMR-4110>

  • At the above prompt type “rm_usb” and press the “Enter” key. The USB repair process will initialise.
  • After a short time you will be prompted to enter the “Start MAC Address” Type in the router’s MAC address (the one you should have noted earlier from the barcode label) – Enter it in 2 digit pairs with a hyphen in between “-”each pair of digits. For example: 00-06-4F-15-39-5A
  • You will also be prompted to enter the “End MAC Address” This is the same for all routers and should be entered like so: 00-06-4F-FF-FF-FF (This should already be the default so you should be able to just press the “Enter” key. The reprogramming of the router will then continue and after about 60 seconds you should see a message indicating that the process was completed successfully.
  • Once the process has successfully completed power off the router, disconnect the USB cable and carefully remove the jumper
  • Replace the top cover of the router, screw it back together and stick the rubber feet back in place.
  • Power the router on once again. Do not connect any other cables at this stage. The router will then reset itself (be patient as this can take up to 2 minutes) and the ADSL LED will start to flash continuously

STEP 4: Reconnect the router as before

  • Reconnect the router to your ADSL line and your PC and restart your PC remembering to change the boot device back to your hard drive. Also remember that you need to re-enter and save your ISP login details to the newly repaired router

Important to note:

If you accidentally lose the Safecom CD then download it from the link below.

Benefits of Home Networking

Why Home Networking? The concept of the Personal Computer has become popular since the Third Generation of Computers proliferated in the consumer market. Since then, computers have become part and parcel of almost every home. In fact, at present, there are many homes housing more than one computer, one for each member of the household. At this point, having these computers connected in a home network or a home area network (HAN) using a home networking solution has numerous advantages.

Home Networking Advantages

A home network is a residence-based local area network and it connects multiple computers within the vicinity of the residential area. The simplest of home networks usually connect two or more computing devices so that files, printers, scanners etc. can be shared between these along with a single Internet connection. For increased functionality a server may also be added.

One of the major advantages of home networking in a house with multiple computers is that Internet access can be provided to all the connected computers with the help of a home networking setup in spite of there being only one computer that is physically connected to the Internet via a modem. This is one of the main benefits for which homes with several computers look towards home networking.

File sharing is another such advantage provided by home networking, providing an extremely effective storage solution. In most home computers, there is a build-up of old files over long periods of time. When new files must be created and stored, it may so happen that there is not enough space on the hard disk of a certain computer which contains too many of such old files. An effective way of dealing with such a situation is to transfer files from the computer to any of the other computers connected in the home network which have adequate memory space. In fact, one computer can be designated the “file server” which stores all these files and every time the file needs to be accessed, the networked computer just has to connect to the file server and retrieve it. As there is only one storage location, data handling is simpler and disk space is saved. Information exchange also provides a big boost to multiplayer gaming and easier file printing by printer sharing.

Home networking generally needs a manual setup. Connecting cables physically interconnect the computers in the home networking setup while hubs, routers or switches interconnect the connected computers to allow file sharing. These devices are therefore information ‘distributors’.
