I have a Qosmio X500-13R with Ubuntu 14.04 LTS in dual-boot. Since I installed it I've had an issue with the wi-fi speed. It connects just fine and has no problem accessing any website. The thing is the speed doesn't go further than 300 KB/s although I have a 100 Mbps connection. I didn't have this problem with Ubuntu 13.10. Has anyone been able to find a solution?
