Hi Guys
I am using a Packard Bell laptop and up to now was able to hit the internet button and i'd be online. For some reason now it cant find the server..I've tried to reconnect but now it tells me 'wireless connection unavailable'.
Ive tried right clicking and searching for available wireless networks but they have disapperared! when I try the advanced option and refresh I still get nothing! I've probably changed some setting unknown to myself but I cant figure out what, someone please help I'm driving myself cracked trying to figure this out! Thanks!

you need to check what ip address your laptop is using.
goto start/run type cmd, hit enter.
type ipconfig /all and hit enter in the dos window that comes up.

you should see something similar to below.


D:\Documents and Settings\Dave>ipconfig/all

Alternatively it could be similar to below.

you need to compare these details with another computer that is on the same network as you. that connects to the internet through the same router/modem.

they should be identical apart from the last digits in the ip adress . these need to be different by a couple of numbers.

ie.
your computer 192.192.192.35
the other computer 192.192.192.40

or someting similar.

if they compare and are as they should be then we need to look elsewhere.

if they aren't then we need to change the ip address of your computer to one that is nearly the same as the other one. bearing in mind that you can only have one machine having one ip address. no two machines can have identical ip addresses.

if you need assistance in changing the ip address then please do not hesitate to get back to the forum.

could you do the following.

D:\Documents and Settings\Dave>netsh (enter)
netsh>diag (enter)
netsh diag>show test (enter)

this will run a test of your network from your laptop outwards.
it will ping all the ip addresses that it needs to with a result.
giving a similar output as previously but in greater detail.

when this is done, right click in the blue bar at the top of the dos box and select edit/select all.
then press enter. this will copy the contents to the clip board. paste this into your message and post back to forum.
