So i recently purchased a new laptop, Lenovo y580, came with win7 home premium, 8gbs ram. But i noticed the downloading speed is around 30-100kb/s, which i have no problem getting 1mb/s on any of my other computers. I'm using comcast and i really doubt its their service, i've been googling for the past few days to look for solutions. I tried to upgrade my wireless router firmware, reinstalling the wireless adapter, and they didn't seems to work. Can anyone out there kind enough to help me?

Being a new laptop, they usually come w/ plenty of bloatware, which might impact performance, esp. anything involving anti-virus/anti-malware. I would try at least disabling it, if not uninstalling it.
Just to be absolutely sure it's not a hardware problem, boot a live Linux CD (e.g., Ubuntu) and see if performance improves.
