Have you tried using another router just to test it?

Take a look at

And see if this solves your problem.
Does the router has the latest firmware?
Perhaps you can upgrade.

Kind regards

Ahh, repo, you win this one. It didn't dawn on me that most likely he was using wireless N. On my linksys wrt350n I had issues with the wireless N, but after I disabled N, everything was fine.

My router is D-LINK DIR-615 and its firmware is customised by virgin media (my ISP). SO I'm not sure if I should upgrade it to d-link's latest firmware or not, since my router is a D4 version and d-link support site only offers firmware for D1 and B2 versions or the router.

About the N wireless, I'm not really sure how to proceed, I'm a bit sceptic about it, since I don't want to mess anything up and then not have anything functional. Should I just type the commands in the terminal as instructed?

thank you, and sorry if I sound too stupid.

Yes, just type them at the command prompt.
If however it doesn't work or the problem isn't solved, you can undo the changes by removing the line
Code:
options iwlagn 11n_disable=0 11n_disable50=0 swcrypto=1 swcrypto50=1
in
Code:
/etc/modprobe.d/options.conf
and rerun
Code:
sudo modprobe -r iwlagn && sudo modprobe iwlagn
Kind regards

thnx for your help repo, but still after following all the instructions and disabling N wireless as I understand, the problem persists (having half my internet speed over wireless). I am now convinced that the problem is within the firmware if the router, since I don't think there anything else interfering with the wireless.

You could always analyze the wireless interference, but I don't think you have a wifi analyzer laying around

I've been looking around for wifi analysers and I am thinking of downloading wireshark or Nessus. Do you suggest any of these or do you know of anything that worth's downloading?
