Because what you wrote (e.g., "brackets", "spreading") literally doesn't
make sense.

What could? Brackets? What kind of brackets? Plastic or metal?

Actually it doesn't. There can be problems even with "excellent" signal
strength. The usual issue, again, is radio frequency INTERFERENCE.

"Covering"? How do they do that? You mean doors _in_ those walls?

Makes no sense. You've got some other issue.

In fact you may have reduced interference by closing those doors. Can't
really say because you've provided so little information and paraphrased
so much I can't understand what you are trying to say, much less what's
actually happening.

>Buying a 5dbi antenna improves signalling quality/noise reduction?


Depends:
* A higher-gain _omni_ antenna may well amplify noise as much as signal.
* A higher-gain _directional_ antenna is more likely to _reduce_ noise
while increasing signal, thus increasing the all important
signal-to-noise ratio.

>I have a standard 2dbi antenna.


If you're lucky -- many aren't even that good.
