I have tried (2) dell m90 and (1) dell m6300 laptops at home.
As soon as I ask the laptop to connect it shuts down my wireless network; It shows the network is available - I ask it to connect - it then shows the wireless network as running but unavailable. In addition any other pcs running off the wireless connection will fail.
I have 2 wired pcs and one wireless running from the single router. All work fine until I attempt to use the laptop.
I'm running a linksys G wireless network without firewalls or secure log-ins. (There isn't anyone close enough to piggyback onto my signal.) I am using it strictly for internet access. Hard drives are not visible through this connection..
This router is connected to a Cisco modem.
All 3 laptops will connect to other wireless nets. All have factory installed wireless cards/chips.
Calls to my internet provider have been fruitless.
(Until I solve this issue I am forced to commute 3 hours a day.)
(So far no one has even heard of this phenomenon.)
