I am attempting to establish an ad hoc network between my desktop computer and a laptop. I have succeeded in connecting the two and sharing an internet connection (ADSL, connected to the desktop), with one oddity – after a period of inactivity on the network, the two computers lose their connection and are unable to reconnect until the desktop computer is re-started. The desktop computer is running Windows XP, and has its power settings to “Always On”, and is not going to sleep, parking the HDD, or even engaging a screen saver – it simply blanks the screen after five minutes of inactivity. The network will continue to function for some time after this – perhaps up to 45 minutes – before it inexplicably drops out and cannot be restarted until the desktop computer is restarted. As soon as the desktop computer is restarted, they can connect again.
I’m afraid I do not know the model number of the PCI card as we have recently moved house and I have not found it’s original packaging as yet. The laptop has a Belkin PCMCIA 802.11b/g card whose part number is F5D7010. I suspect, from what I can see on the Belkin site, that the PCI card is the F5D7000, but I’m note sure whether it is version 1, 2, or 3.
Is this a common problem? It almost seems that there is some kind of time-out or power-saving measure that is being applied to the desktop PCI wireless card, but as I said, the computer’s power management is set to “Always On”, and on the advanced settings for the card itself, I have set it’s power management property to CAM (Constantly Awake Mode).
Anyone run into this before, or have any suggestions as to how I can keep the network alive?
PS: Interestingly, disabling and the enabling the card on the desktop under Hardware Profile also fixes the problem instantly.
