[schiehallion]

Help. im going demented, whilst i was working away my mrs had probs with logging on via our modem, she finaly got it sorted with help from aol and everything is hunky dory for her, but now im home i cannot log on with my lap top, it seems she changed the name of our net work, and now when i try to log on it comes up saying im connected with 54.0Mbps strength excellent, acquiring network address, i have tried the trouble shooter and it says i have an invalid IP address 0.0.0.0 subnet mask 0.0.0.0. when i click on repair wireless network connection it says windows is renewing my IP address, this has been on for over an hour now. any suggestions people?

wired or wireless?

open a command prompt
type ipconfig

will show something like this

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.2.168
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.2.254

then type
ping 127.0.0.1

should say
Pinging 127.0.0.1 with 32 bytes of data:

come back with your results

gateway is your router .... so that's important

it is wireless and the figures are 0.0.0.0 for ip addy and subnet mask im about to try yr suggestion now, i hope yr right cos i am way out of my depth here

So the TCP stack hasn't fallen over then, thats good :)

Sounds to me like you have got the wireless network key wrong, I assume you have windows XP!

XP is a pain because if you use the wrong network key to connect wireless it will connect and won't report any errors but you will not be able to use the connection and your router won't assign you an IP address (thats why your getting 0.0.0.0)

disconnect from the wireless network and then connect again and it should prompt you for the wireless key again, re-enter it and it should work OK

If you don't know the wireless key then you will need to use the other compuer that does work to login to the wireless routers admin pages to get it, if you need help with this post back with make of router.

got thank you. i was making the mistake of inputting my 26 digit security code instead of the new password that had been assigned to the router ,my mrs forgot to inform me there had been a change of password thank you again.

chuck has the next bit covered


just to explain what I asked you to do
the rough guide
127.0.0.1 is the network within your machine - so if you ping (send a test message) and it replies it's an indication that the drivers and hardware are correct

ipconfig shows the other side of the hardware - the bit that connects to your router/modem

generally a network address is allocated automatically by the router
(known as dhcp) - if dhcp is working ... and the connection is there - it isn't talking to the router you generally get a 169 address

if the connection is there and dhcp is off (with wireless it's generally because the key is missing) you get 0.0.0.0

if the connection isn't there at all ... you get an error message

so you now know all about networking

you beat me

Networking 101 from AC :)

Wish it was all that simple (actually no I don't, that would put me out of a job!)

[ACtheTROLL]

i'm drained now .... networking 102 is too advanced for the likes of me - book laarning isn't my strong point guvnor
