I have a very bad signal strength when my laptop is about 4-5 meters away from the router. The wifi struggles to connect, and when it eventually connects the signal is very low, about two bars.

My software and hardware:
⠀Samsung ultrabook series 5
⠀Ubuntu 13.04

my lshw :

*-network               
   description: Wireless interface

   resources: irq:45 memory:f0500000-f0501fff

Any hints how to dive a little more into this problem?
