Firstly a caveat, this is simply the way I would approach it. If you have a better way or any suggestions please add them.
Instructions are generic and presume Windows XP, for specifics relating to your wireless device/router please consult the manufacturers documentation where appropriate
—-
Stage 1:Initial Steps
a> Check firmware version of wireless router and download the latest from the manufacturers site but don’t upgrade yet
b> Download latest drivers for your wifi card but again don’t install yet
c> Disconnect WiFi device from your internet connection
d> Turn off all other wireless devices
e> Turn off all security settings on the router (hence steps c & d)
f> Ensure wifi is turned on on the device you are testing from( on the Sammy check the 3rd
blue light from right illuminated)g> Try connecting
If connection succesful jump to stage 4
Stage 2: Fails to connect
a> Make a note of all your internet connection settings, customised firewall settings etc. If the router supports it make a backup of the current config
b> Factory reset the router to defaults
c> Try Connecting
If connection succesful jump to stage 4
Stage 3: Still fails to connect
a> Upgrade wifi card drivers & retest
b> If still unsuccessful upgrade router firmware, If success jump to stage 4
c> If still unsuccessful set router to use B only rather than mixed mode/G/N whatever (ie use the lowest common denominator)
d> If still unsuccesful try connecting to alternative make of wireless router (don’t have one? then pop down your local Macdonalds. Not sure what kit they use but the Sammys definetly connect no problems)
e) If still unsuccessful Cry and consider a warranty claim/return
If steps c or d above work consider swapping out your router
Stage 4: Initial Connection succeeds
Congratulations that’s the hard bit done , time for refinement. At each step check that connection is stable before moving on
a> Try accessing your routers configuration page via a web browser
b> enable Mac address filtering if your router supports it else skip to next step The mac address of your device can be found either by running ipconfig from a dos prompt (windows: start |run|cmd|ipconfig) or depending on the router it may be listed/recorded under an attached devices page
c> Re enable your wireless security.
If connection fails at this stage try alternative security settings. If connection still fails upgrade drivers and then firmware if not already done.
If you’re really unlucky and connection still fails beg, borrow or steal another make of router
d> Restablish your internet connection and ensure you can access external webpages.
If you can’t then move to Stage 5 other wise , congratulations.
Stage 5: Can’t browse
(this is only a very basic guide)
Turn on one of your other wireless devices and test from there.
If that works then open a DOS prompt (start|run|cmd) and type in
ping 66.102.9.104
and press Enter
You should get 4 sent/4 received
If not then you may need to seek advice (or wait for me to write a more in depth article)
If you do then type in
if you get any error message about host not found etc then your DNS settings are fubarred
If ping is succesful but you still can’t browse then things to check are Anti virus programs, firewall programs and proxy settings
