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)?

I think you'll find that some wireless cards just don't yield the maximum throughput. I've run speed checks on my connection here, 15mbit/15mbit fiber, and my Toshiba running XP-Pro gets 15mbit, but the HP running Vista-32 only manages around 9mbit. Never been able to squeeze any more speed from the HP on the speed test.
