Okay so now you have to think when this bottle neck started?
Is it because you moved the monitor near you?
Is it because your mobile is close or between you and your router?
Keep an eye on it,
you will find that most wiress set ups fluctuate up and down,
but you can still get a connection.
This is why we laugh when peeps think wireless is great,
its goog for short bursts but a pain if your online alot
as you see the weak signals and loss of connections more
than most people.
Either live with it, or think about a cable from your
laptop to your router
