Internet Problems?

This website will test for common internet problems..

Connection problems

There are a whole bunch of reasons why an internet connection is not working, this page has useful information on fixing the problem. Are you using wired or wireless? the difference? Wired, you have a physical cable connecting your computer to the internet, wireless, you are using a wireless adaptor to connect - laptops have this built in.

Here's a list of steps to get a computer back online:

If you are using wired broadband...

  • Check that the internet connection is actually connected fully in to the back your computer. Broadband connections is either a RJ45 ethernet network cable or a USB cable. If you have an ethernet cable, then you should see a flashing light where the cable is plugged to indicating that its connected and receiving data.
  • Check that the modem is correctly connected. Your modem should have your phone line connected to this, and another cable going from the modem to the computer. Check that the modem is switched on, and that your phone line is still operating.
  • Check that your modem is operating correctly. Look and read the lights. It may be necessary to turn of your modem for a few seconds, and switch back on.
    .For BT Hubs only : make sure the 'broadband' light is blue, as this indicates that your modem has successfully made a connection to the internet. If this is off, then BT will ask you to try connecting the Home Hub directly in to the main phone socket (ie. without any other phones or extension leads). If that still doesnt work, then is most likely broadband is not comming down your phone line.
  • You may need to contact your ISP
If you are using wireless broadband...
  • Are you too far away from your hub? If your wireless broadband was previously working, and keeps playing up; the most common problem is that your computer or laptop is too far away from the modem. You can check this, by clicking the network icon in the bottom right of your screen, it will tell you 'signal strength'. If you signal is low then, If possible, try moving your modem or your laptop to a better position.
  • Have the correct passkey? If your wireless connection, says its 'connected' but you cant get any web pages up, then the most likely problem is that you have a problem with the passkey. If you are not familiar with this, its advised you get someone to fix this for you. The pass key can normally be found written on the modem or in the installation instructions that came with it.
  • Also note, that 'connected' means your laptop is able to communicate to the modem; doesnt necessary mean it is connected to the internet.
  • Check for possible sources of interference. You maybe getting interference from some other electrical equipment. CB radio etc..
  • Modem out-of-date? If your modem is over a year old, you may need to update the firmware in the modem. You will need to login to your modem to do this.
This applies to both Wired or Wireless broadband...
  • Phone line problem? Sometimes, the modem has problems sending and receiving data down your phone line because of a faulty phone extension or faulty phone in the house. Try disconnecting all your phones except for the modem to see if this works.
  • Empty broswser cache. Trying clearly your browser cache. Any computer that uses the internet builds up lots of files. Everyime you open a web page, all its content and images are actually put in to files as they are displayed on your screen. How to delete these files are slightly different depending on what type of computer you have and what kind of software you are using. In most cases you should open a web page, and click Tools > options > Delete cache.
  • Check your proxy settings. In most cases, especially home computers, dont need proxy settings. Setting a proxy will stop your internet from working. Some viruses will create a proxy. To remove it, open IE, click tools, options, connections, and delete any proxy settings.
  • All off and on! If you still got problems, Try switching everything off. The computer and the modem, once all off for 10seconds, turn on the modem, wait 2mins, then switch on the computer again.
Still not working?...

    Ok, weve tried the simple steps. If you still have problems then it now gets a little difficult to fix.

  • Try a ping! For this, you need to open a DOS box. To open a DOS box, click start > Run > type 'command' then enter. You should now have a black box. Type 'ping 127.0.0.1'. If you get replies, then it doesnt mean its connected to the internet, but it could do. If you dont get replies, then it means you have problem with your computer's network adaptor.
    Type 'ping www.google.com'. It will now send little bits of data to Google, and Google should send them back. If you dont get a reply, then your computer is unable to contact the internet at all. If does reply, then your internet connection is fine. Its likely you have problem with your browser (internet explorer, firefox, chrome are browsers). Viruses often cause this problem. Check for viruses, then
  • Connection utility. Try the iCheckConnection from pc pitstop. This also performs other types of checks that may help in fixing the issue
  • Check your browser. The problem may just be with your browser software. (Internet explorer, Firefox or Chrome.) If you have recently installed something, or have had a virus, this would quite likely interfered with how the browser works. The fix to this can be any to a small setting change to reinstalled, updating or download a different browser. More details on how to the fix fix internet explorer problems can be found on the link.
  • Check your firewall. Though rare, your own firewall maybe blocking your access to the internet. To check for this, temporary disable it to see if this resolves the issue. If it does, then you need to look deeping to the firewall settings to find out why its blocking you.
  • Try this:

Dialup Modem problems

    If your using the old dialup system and you not getting speeds above 40k then you might have a problem. If your living in a town or city then you should be getting good connection speeds. Some out of town areas will have problems because of the distance between you and the nearest telephone exchange.

  • Try a different modem, though I usually recommend external modems, I have come across a few internal modems lately that gave alot better connection speeds. (mine was a constant 52k). Make sure your modem has v.92. (biggest difference is in the upload speed), Modems are quite cheap to buy nowadays.
  • Buy a high quality modem cable (usually costs about $20, or 12) If your using telephone extension leads, then make sure they are of good quality too, and make sure they dont run too near power cables, as it will pick interference from your electrical equipment.
  • Unplug any other phones you have connected. This often makes a big difference. You might find that one of your phones is the cause of your internet connection problems.
  • Increase port speed. If you have an external modem which is connected to a com port (most do), then you can increase the com ports serial speed to the maximum. This can be done via the device manager console.
  • Tweak the registry. There are a number of registry tweaks, which basically changes how data is transmitted, be very careful. A lot of software claiming to increase your modem speed, but they just make the same registry changes. You might get a 5% improvement, but not 100% like a lot of information you might read. Search for information about MTU settings and receive buffer settings; plenty of information can be found on this. MTU is the data packet size. Receive buffer, is how much data your computer can receive before sending an acknowledgement back.
  • Update your drivers. Download the latest modem drivers from the modem manufacturer website. An incorrect installation may leave you without an internet connection, so make sure you download the correct driver - recommended for more experienced users.
  • Improve your phone line. If your line is crackly, hissy or quite when talking to people, then you should ring your phone company about getting it fixed, as these problems will also be effecting your internet connection. Most companies can easily run a free line diagnostic test and will be happy to send an engineer to fix it. Quiet lines just need a little more gain added, which is done from your local exchange. If you still have a poor quality line, hassle them to get the cable replaced.
  • If the above advice doesnt work then will recommend contacting a local expert, as further advice is quite technical and out scope of these instructions.
