Thank you for your Post. From your description it appears that he wireless adapter might be failing, or your system may be suffering from a severe case of corruption.
If this set up used to work correctly in the past then you may try doing a system restore to a date when it still worked correctly, see the link below for instructions on system restore.
If this does not reset your system to a working state, or if it never worked correctly then you might be looking at a hardware issue, in this case we recommend you to contact your laptop manufacturer for a warranty support. A hardware issue may refer to just the wireless adapter or its connection on the motherboard
