Sharing a connection with other users in your household is a great idea. It allows you to share internet access, transfer files, share a common printer, and even play multi-player video games directly connected. However chances are you will run into problems that will overall slow down your own connection speed, or even create outside problems. Typical issues will include the inability to transfer files, conflicting IP addresses, and speed problems.
Let us first look at file transfer problems. File transferring allows you to directly send a file to another computer on your network without having to use your internet connection. To have this ability you need to make sure that you have the “Turn on Windows File Sharing” box ticked when making your new household network connection. If you have already made a network connection you can change the properties by right clicking on your current network, hitting properties, and then checking the box labeled “File and Printer Sharing for Windows Networks.” Sometimes you might accidentally change some settings that make matters worse. In that situation all you have to do is right-click your current connection and click “Repair this connection. Next we need to verify the Windows firewall is not interrupting. Under properties, go to the Windows Firewall section and make sure “Don’t Allow Exceptions” is unchecked. Then go to the Exceptions tab, and make sure you check the “File and Printer Sharing” option.
Every time you connect to the internet, your computer will pull a random IP address from your router. It’s almost like an identification tag for your computer. However every time you connect, your computer will pull a random number. When this random number is chosen, sometimes it conflicts with another computer or device using the internet. To solve this we need to set up a static IP address. To do this first hit your Windows key, next click on run and type in cmd. Your cmd or command prompt (black box) should open. Inside your cmd type the code “ipconfig”. Doing this will give you your current IP address, subnet mask, and DNS gateway. Remember these numbers. Then go back to your network connections properties and left click once on Internet Protocol (TCP/IP), and hit properties. Here is where you set your static IP address. In the first box enter your original IP address but change the last digit. Generally keep this number at 2 through 51. 51 is generally the most addresses common routers take, therefore is the highest number it can take. Then enter all the same information into the corresponding boxes that you received in the cmd prompt. Hit save, and now ever time you connect, you computer will grab that static IP you set, no more conflictions! This also allows you to port forward programs.
Sometimes your internet can just be a pain in the butt. Many times a simple solution is to restart your router. Simply unplug both your modem’s power cord, and the router’s power cord. I would suggest leaving it alone for at least 5 minutes before plugging it back in to give it time to reset. You may also restart your computer while waiting for your router to reset. Networking is a very broad topic, so while I can cover a number of quick-fixes, it would be impossible to say theirs an exact solution for each networking problem. Many times solutions involve applying multiple fixes. So don’t give up if one thing doesn’t work, keep looking and trying as many tweaks as you can.
