Alienware m15x - wireless packet loss

Good morning,

I have a tiny problem with my laptop.

Yesterday I noticed that I have a packet loss to my AP, it's really odd because distance is two meters and all other wireless devices at home have no problems at all.

I'll try to decrease a maximum speed, so now is not that bad and could be used, however I bought gaming laptop for gaming purpose not for browsing internet ;).

Can anyone help me or give me any clue what should I check?

Regards,

R
