Home Networking Troubleshooter

If you have not setup a home profile click here

If you are having trouble connecting at home, identify the where the problem resides.

     1) Wireless appears OK but no Internet anywhere (including IHA).
    2) Wireless works fine everywhere except home.
    3) My wireless icon has X (not connected) but other wireless laptops connect to the Internet through my router.
    4) No computer can connect through my home router.

MAKE SURE YOUR PROXY SERVER BOX IS UNCHECKED (IE - Tools - Internet Options - Connections - LAN setting) This must be checked at school, unchecked at home.

Internet Explorer may be broken.   Try a different browser (Google Chrome, Mozilla Firefox).  Internet Explorer can often be repaired - Tools - Internet Options - Advanced - Reset (near the bottom)

Most wireless networks require an Encryption Key. Your profile in Think Vantage / Access IBM Connection must be set up with the key (password) if your router requires it.  Check other machines in your house that ARE connecting wirelessly. Copy their settings.  Encryption Key management

A new router (D-Link, Belikin, Linksys, NetGear, etc.), straight from the box, should immediately work with a CABLE modem without any change in router configuration. I suggest disabling encryption.  Make sure your cable from the modem is inserted in the single WAN port (not one of the LAN ports) of your wireless router.

Your router can be "N" ,"G" or "B".   They are completely compatible.

Try connecting to a neighbor's unencrypted network (or a library or Panera Bread).  If you connect, the problem lies in your home router. Try deleting your home profile in Access Connections and set up a new profile (Find - Connect).

You can try disabling the Wireless Connection then re-enabling it.  RightClick My Network Places - Properties. Right Click Wireless Network Connection - Right-Click - Disable. Wait until it is Disabled. Right-Click - Enable.

You can try Uninstalling the drivers for your Wireless Card and reinstalling. RightClick My Computer - Properties - Hardware - Device Manager - Doubleclick Network Adapters - RightClick the wireless adapter - Uninstall.  Once uninstalled, click the computer with the magnifying glass icon on the top.  This will "discover" your wireless adapter and reinstall it.

Certain cordless phones and Microwaves send signals on the same wavelength as Wireless Internet. If your wireless connection is often lost, see if it happens when phone or microwave is used.

If you just do not get the Internet:

Try a different browser ( Google Chrome, Mozilla Firefox, Internet Exploere )

MAKE SURE YOUR PROXY SERVER BOX (IE - Tools - Internet Options - Connections - LAN setting) IS UNCHECKED!  This must be checked at school, unchecked at home.

Make sure your home desktop can access the internet through the wireless router.  One network cable runs from the Cable (or DSL) router to the WAN port of your wireless router.  Another network cable runs from any LAN port of the wireless router to your home desktop.   If your desktop connects to the Internet, the problem is in the wireless.

Try taking the network cable out of your desktop and into the LAN port on your laptop.  Can you connect with a wired connection?

Router wireless settings:

Following the directions in the wireless router's manual, use Internet Explorer to "configure" the wireless router (usually by typing 192.168. ? .1 as the Internet Address - ? is usually 0, 1 or 2 depending on the router brand).  Account is usually admin with either no password or "password" as the password. Google Search the Most of the default settings are fine.

Your router MUST have DHCP enabled. If you fill in an IP address to match your home settings it will NOT work at IHA.

I would recommend that WEP (encryption) be disabled. Once you're up and running you can re-enable it if you really want to, however real hackers will not sit in their cars, trying to steal secrets and passwords. (There are more efficient methods of hacking). I find it helpful if we all share our connections and thus connect wherever we happen to be - "I have always depended on the kindness of strangers" - Blanche DuBois

Close Neighbors?  If your neighbors have wireless, your routers may be conflicting. Try the following:

Choose wireless channel 1, 6 or 11.  If your laptop detects other networks (your neighbors), set you channel different from theirs - less interference.

Choose your SSID to be unique (your last name perhaps).

Consider changing the IP address of the router. By default it is 192.168.?.1 (? is 0,1 or 2 depending on brand). If your neighbor uses the same IP pool, communication can be affected.  Change the third digit to a number between 10 and 254, which should make your wireless network unique in your neighborhood. Once you change it you will lose contact with router's web page since you must then access it by its new IP address. The DHCP server should then hand out IP addresses with a matching 3rd number

You do not need to be in the same Workgroup as home computers to use the Internet.

To see files and printers on other home computers, you can join the same workgroup (MSHome, Default, Smith, etc.) as the other home computers and the files and printers must be shared on those home desktops.  Try typing ||desktop (where "desktop" is the name of the workstation that is sharing). Do NOT enable file sharing and printing on your laptop's wireless network connection.  It is not needed and will only serve to add your laptop to the list of school servers and you'll get chastised by Mr. Hotz.

Join your home workgroup by right clicking My Computer - Computer Name - Change - Type in workgroup name.  No account or password is needed - just press OK.  You MUST rejoin the IHA Domain AT SCHOOL to get access to printers and teacher folders at IHA.  Repeat the above process but give it account admintemp with password bosco as you join the IHA DOMAIN (although IHA workgroup seems to work fine).

Still not working?  Invite your friends over with their laptops.  Go to their houses with your laptop.  Who connects to who(m)?  Is the problem in your laptop or your router.

Apple AirPort routers can be made to work with your laptop, but it is not as easy and I cannot give any advice.

** If all this fails, you can try letting Windows control the wireless connection on the laptop (instead of IBM access connections).  RightClick My Network Places - Properties. Right Click Wireless Network Connection - Properties - Wireless Networks Tab - Check Use Windows to configure my wireless settings. OK.  Now right click Wireless Network Connection - View available Wireless networks and choose your router. Windows is now bypassing the IBM drivers.  Perhaps this works better..
