|How could you disable one wireless network???|
You can disconnect from one wireless network but not disable one.
You can disable the wireless network card, that's correct.
You also cannot connect to two different wireless networks with only one wireless network card.
Are you really connected to both wireless networks or are there simply shown 2 different networks.
I ask, because when two or more wireless networks are shown in the available network list, that does not mean, that you are connected to them.
The original poster should always write the last response !!!
Let us know, if the problem is solved !!!
