I have a client with a Dell Studio laptop running Windows 7.
They also have 2 other mac books and an ipod that connects to their new wireless modem in the house.
All other devices work fine, including PC connected via cable, however the Dell laptop is not consistent with its connections.
i have been there twice and both times the dell laptop has connected OK to the wireless network, however at different times of the day, it will lose the network and be unable to find it or connect ot it.
Even a restart of the laptop does not help.
After leaving it for the day then starting again the next day it will all of a sudden find the wireless network and connect to it.
I have checked wireless drivers, wireless networks set-up in Networking and sharing center and disconnected and re-connected the wireless with the correct password to the wireless network numerous times.
The only thing I can think is that the wireless card in the laptop is faulty.
We very recently replaced the wireless modem in their house. I think the wireless on the laptop played up once or twice previously, but after the new modem has gone in it plays up frequently.
As other devices are connecting fine, I do not think it is the wireless modem
