Trying to connect my XP laptop wifi

Specs: xp SP3
Hi, I am trying to connect my XP laptop to a wifi signal being provided by my Imac computer. I can see the signal as a computer-t-computer ad hoc network (or I can set it so that it is a true wireless network). Either way, I cannot connect to it, even tho the PC says it is connected. I just can't do anything once it is 'connected'.

I know this is a common fault and there seems to be a myriad of reasons why it doesn't work but it really is confusing me. I tried with no firewall and it made no difference. I am sure the Mac is sending the signal out OK, and I am not using any passwords at the moment as I am trying to do this simply just to get it working.

If anyone has any suggestions that they could spell out for me easily, I would appreciate it.

I'm not a networking genius, but had a similar problem. I know you said "...I am not using any passwords at the moment...". Are you SURE your signal isn't encrypted via WEP or other means?

Absolutely. I'm creating the network and I have no passwords. I have even tried to allow my son's Nintendo DS to connect when I make it a fully fledged wifi signal but it also cannot do so.

Thanks for the link - I've done all of that and it works fine as far as the signal leaving the mac. Just can't connect to it though. I really think the fault lies with Windows.

XP will find available wireless connections within range of your laptop when you have a wireless adapter installed and enabled, but that doesn't necessarily mean you can access them.

Usually doing this is easier....
When you search for and look at the wireless connections available in XP on the laptop, if the connection has encryption enabled, when you click on it or double click on it, it will prompt you to provide a key (code), or in some cases a password that is used to load a key (code) automatically.
In most cases, XP finds most if not all other settings your wireless adapter on the laptop needs to be set to automatically, so you don't need to set up the wireless adapter on the laptop.

Wireless connections often have encryption enabled because otherwise anyone within range can access your computer wirelessly. If it isn't using encryption, it may be using a filter of one type or another, or it may be using both encryption and a filter (see below).

If the IMAC adapter is using encryption, and/or a filter, you must determine which type it is using and what the key (code) is, or do what you need to do to conform to what the filter needs.

.......

The alternative ....
In XP with SP2 updates or above, if you use the wizard to set up your wireless adapter, it requires you use encryption and enter a key that is the same as for whatever you are trying to connect to, or it can generate a random key automatically. The SSID must be the same on both ends of the connection, whether you use encryption or not. If whatever you are trying to connect to does not have encryption enabled, you have to use the same type of encryption and key and SSID in the configuration of whatever you are trying to connect to.
After the wireless adapter has been set up using the Wizard, or otherwise, Windows shows the encryption key as only ******** once it has been entered - if you want to know what it is, have it make a floppy at the end of the wizard, or have it copy the same files to a USB drive - the key is in plain text in a file on that.
Or - you can use the floppy or USB drive in the other computer you want to connect to in Windows, and make the settings on both ends match, but obviously that probably will not work on the IMAC, and that does not always work in XP (and 2000) and sometimes you have to enter the key type, the key, the SSID, and maybe other settings manually, so they are the same on both ends.
......

If the connection DOES NOT have encryption enabled on either end , and you still can't connect, or if it does and you have used the right encryption type and key and you still can't connect, there may a filter enabled for the connection you are trying to connect to, such as MAC Address filter (that has nothing to do with Apple - it's the unique number/letter character identity string all networking devices divulge when quieried) - e.g. in that case the MAC address of your laptop wireless adapter must be added to the MAC Address filter allowed MAC addresses list in the configuration of whatever you are trying to connect to, in this case in the configuration for the wireless adapter on the IMAC.


When you connect from a wireless adapter to a wireless router, usually you use infrastructure mode; when you connect from a wireless adapter to another wireless adapter, usually you use you use ad hoc mode, but as I have already said, usually XP finds that automatically, when you use the search for and connect to available wireless connections method.

.....

If you enter a WEP key yourself, a 64 bit key must have 10 characters, letters or numbers or both; a 128 bit key must have 26 characters; the case of the letters is important - whether they are upper or lower case must be the same on both ends.
