Quick question - 150Mbps wireless

[Mr. Pedantic]

I have a wireless connection that in my laptop is showing up as a 150Mbps connection. It's about 10-15m away from the router and switch (probably closer to 15; I haven't done any proper measuring), and there are 2 walls and 2 doors in the way (all 4 are largely hollow, plaster/wood - nothing metallic or particularly solid). Could someone give me a rough estimation of a realistic transfer speed I should be getting?

I would be happy if my 802.11G went faster than 25mbps actual throughput 🙁

30-40 Mbs would be reasonable.

30-40? Really? Even 15m away, through 2 doors and 2 walls?

Wireless is half duplex and has a TON of management traffic, retransmissions. 150 is the data rate, the rate at which the transmission is clocked. Getting even half of the data rate is considered pretty good.

Actual transfer?

Copy a 100MB file fRom a Wireless computer to a wired computer.

It takes 60 sec. then your transfer is about 1.5MB/sec. (or 12Mb/sec.).

It takes 30 sec. then your transfer is about 3MB/sec. (or 24Mb/sec.).

It takes 20 sec. then your transfer is about 5MB/sec. (or 40Mb/sec.).

It takes 10 sec. then your transfer is about 10MB/sec. (or 80Mb/sec.).

I was led to believe that 30-40 would only be possible if I were sitting reasonably close to the router with only maybe a single wall intervening. But considering that I'm currently getting 10-15Mbps max (it's at 1Mbps around a third of the time), I'd switch for a stable 30-40 gladly at the moment... 😛

I was wondering because I'm getting a guy in from HP to have a look at my laptop in a few weeks (as soon as my exams finish), because of my wireless and because of my screen flicker, and I want to know what I actually should be getting, instead of being fed some bullshit by CS or repair reps that whatever is wrong is 'normal' and my expectations are just too high.

Yes, thank you for this. Except I already know the speed I am getting, and instead want to know what I should be getting.
