Re: wifi question


My experience (very limited) with setting up my daughter's wireless laptop
when she is home from school. I discovered that the Dell Inspiron laptop
defaults to shutting off the CAT5 Lan card when the laptop is running on
battery power. However, the wifi adapter is also "off" unless first set to
search for a wifi access point.

What I did, with a lot of help from the guys here was to set the laptop
default power settings to auto search for a wifi access point when going
off charger and into battery power. Then I set the Laptop's default
settings to not try to set up it's own little wifi network. At least I
think that is what it was defaulting to -- "establish wireless network" was
the message. Then I cold booted the entire system. Looking at the Linksys
wifeless router then revealed that everyone on the network was refreshed
and the laptop was there. So far, plugging into the power adapter and then
unplugging has not effected the wifi capability.


I don't know if this is helpful to you, but hope it is.

Cheers,

Dave
