I'm using Virgin's cable broadband.

I've a question about the speed of my broadband, in particular the one that I receive on my laptop and wondered if anyone around may be able to point me in right direction.

I've a PC upstairs connected to Virgin's modem & wired connected to PC. After upgrading my broadband speed to 10MB (from 2MB).

When running online speed check on 3 different website, the PC upstairs shows around 10MB of speed, however, on laptop it only shows around 2MB.

Laptop shows signal strength of wireless router as "very good" (understandably, upstairs it show "excellent" due to its close proximity to router). However, when I'm next to router i.e. when signal strength shows "excellent" and when I run a search, the test shows the speed of around 5-6MB.

I've disabled ZoneAlarm firewall, Spybot anti-spyware and AVG's anti-virus software, when running this speed test, but it's made no difference whatsoever & remains just under 1MB.

I've also ensured that the channels set on router and my wireless chip on laptop is same. Router's default setting's channel 6 and I've ensured the same set for my wireless chip on on laptop as well.

I've had new modem & router sent out by the Virgin people due to this, but the problem continuous, I'm afraid. Can anyone tell why I fail to get around or just under 10MB of broadband speed on my laptop?

Can investing in new & better router i.e. "N" router make any difference in broadband speed though? (bearing in mind it shows better speed at close proximity to router than running test result downstairs). Though, why would distance from router affect "broadband" speed (shouldn't it just affect the connectivity "strength" alone)?
Nope, I'm NOT God, but I'm British (which is the next best thing ;)

many things can affect the speed of 802.11 systems. other wireless connections in your area (signal crosstalk), quality of the signal within a home, and the ability of the laptop to transmit back to the router are the variables. a pre-n unit would perhaps address some issues, but if you expect to get hardwired speed with a wireless connection, i'm afraid you're going to be disappointed. radio signals are the weak point here. the best solution i can offer is either a repeater if you live in a multi story house (say the wifi router is on the ground floor and you are in the basement or on the top floor), or position your router to provide the best 'hotspot' where you actually use the laptop.
