I have a new Dell laptop, an Inspiron E1505, that has Vista home
premium edition with an intel next-gen wireless n card. I'm
having problems with wireless drops. I'm in an apartment building that
has recently gone wireless. The signal is indicating it's strong, yet
I am dropped back to local access only after about one minute, or
less, on-line. I have no problems connecting, and staying connected, to the internet in a public place,
like Starbucks, so I'm assuming it's an encryption problem, but I'm just not sure. Any ideas?
