Is it possible to get close to 300 Mbps on a wireless laptop ?

I just got a new wireless n router that specs say up to 300 Mbps. I also got a new Dell XPS laptop with wireless n built in. Right now I have std roadrunner cable speed of 6-7 megabit down and 500k up. With my laptop my Mbps is like around 105.

Now if I were to upgrade up to turbo speed around 15 megabit down would that double my Mbps speed to around 200 Mbps ?

Is 300Mbps really attainable or is that marketing number that companies throw out there ? Or do they mean 300Mbps only possilbe with a cat 5 cable ?

thanks

 

You're not going to find any ISP currently that can even come close to matching N speeds in NA. N speeds boast 300mb/s for people who like to stream 1080p content from their laptop to their tv/bluray player, or want to transfer large files on their local network. You won't even see a difference between N and G for the majority of actual net usage for most people.

In reality due to signal loss and other factors N usually only hits ~230mb/s, still plenty. And no upgrading your isp plan will not get you to push that number higher, though it will increase your speed from 7mb/s to 15mb/s

 

Mind you that's not the actual connection speed- the fastest ever 2.4GHz 40MHz channel speed recorded by smallnetbuilder was 111mbps (the fastest for 5GHz was 92mbps)

@Scott111

You're mixing up two things. LAN speed and internet speed. You may be connected @300mbps to your router and have 1mbps connection from your ISP. Your LAN transfers will be way faster than your internet transfer but one thing has nothing to do with another.

 

Yeap in reality you will never hit anywhere near 300mbps. The 300mbps figure you see in windows is just the maximum for the link rate its using.

Upgrading the internet will just increase the speed on your modem which you use to access the internet. It wont make the connection to you router any faster.

With a CAT5e cable on gigabit ethernet (1000mbps) you can get close to its theoretical maximum which is about 125MB/s

 

As the other guys have said, the speed you pay for from your ISP doesn't relate to the connection between your router and your PC. Fact is, you could have a 56K Dialup speed internet speed with a 300Mbps connection or you could have a 101Mbps ISP with a 54mbps connection. Ofcourse you always want your actual connection to the router to be faster than what you buy from your ISP since you'd be wasting money then. Back in the days of 802.11B and a 10Mbps connection, i would actually use a cable most of the time because 802.11B wasn't fast enough but now i have a 30Mbps ISP package and 150-300Mbps router
