Laptop keeps disconnecting from internet HELP!

[Ubermik]

I couldnt see that anyone has mentioned this yet, but a rather silly reason for this is often that by default a lot of network hardware is installed with the power saving option enabled

And even when in use some devices seem to still think they arent doing anything and then power down to conserve energy for some odd reason causing this exact fault

Might not be your problem but worth a look perhaps if it reoccurs

Similar problem with me, but it does not disconnect: instead, it just times out the 'ping' requests, then sometimes normalises, then time outs again. Of course, this stops my internet from working.
What helps is either to change the wireless channel (which requires stable connection anyway), or better to power off the router for 15 seconds. But we all need a constant solution to the problem anyway, so I am curious what is the real reason. My laptop wireless card is the same Intel model, so I think maybe it's the reason? From the other point of view, I now a person with an external USB wireless card, and the same problem with her as well.
