No reception suddenly

[vijeze]

Hey guys. First time poster here so bare with me.

As of late my bb bold 9000 has been getting horrible to NO reception at all in my house. I didn't change anything and here's some things you may need to know:

-I cleaned the sim-card already
-Latest OS
-Rebooted.
-No tweaking with my OS.
-Used to work before.
-Didn't install any additional applications.
-On Vodafone NL.
-Usually it searches for networks, then gets SOS from a different carrier. I used to have all bars 3G internet at my house before this nonsense.

I hope you will be able to assist me in fixing this ASAP.
Thank you very much
