It can help. For instance our laptops here (compaqs, acers) all have this button (some call it Flight Mode) to disable WIFI. With it off what you note happens.
Now I've done some poking around so before anyone jumps on me for not using the search feature while being good advise it will do little to solve my problem.
While not a huge problem and nothing more then a rather large inconvenience I am hoping I am not the only one to have this particular problem. Now I have had this happen to me with both of my laptops one was running XP and the other which I have and am using now runs Vista so I am guessing this is probably a software problem with the windows operating system its self and the way it manages wireless networks.
I only notice this when I am connected to a low strength network hotspot or otherwise of 18mb/s or less. Randomly and without warning I will be kicked from the internet and windows will be unable to detect any wireless networks even though it was once able to detect several. This eliminates the theory of the internet its self crashing unless 6 routers all went down at the same time. I find that after I restart suddenly I am able to find all of my networks again.
I have not the slightest idea as to what is causing this problem so if anyone could help that would be wonderful. Thanks in advance.
