Update.
I'm able to achieve speeds of 2.5-3.1MB/s using my wife's XP laptop. Speed is the same whether the Windows firewall is enabled or disabled. A 12GB file took roughly an hour and my internet connection isn't killed while transferring files and surfing.
This is better, but not by much. Going by Pleb5919's transfer rates in XP, roughly 1GB per 8 minutes, my speeds are a bit above normal.
So, options?
Update 2:
Ok, so my brother in law tested his wireless G connection, which has a similar setup to mine: 64-bit 7 to 32-bit 7 Media PC. Transfer rates were the same for him as mine were to my wife's XP machine: 2.5-3.0MB/s.
Can anyone do a large wireless G file transfer and report speeds? Also, if anyone has an N setup I'd be interested in knowing what sort of transfer rates I can expect to see? There's a card I might get if it'll boost speeds: Newegg.com - D-Link DWA-552 IEEE 802.11g, IEEE802.11n Draft 2.0 32-bit PCI Xtreme Desktop Adapter Up to 300Mbps Wireless Data Rates Wi-Fi Protected Access (WPA, WPA2)
I haven't quite figured out yet why my media pc isn't getting at least 2.5MB/s, so in the interim, I've just ran some cat5 to the back room... but boy is it ugly!
I have had the same problem... The Netgear wireless manager states I am connected at 284Mbs and can only transfer file at about 2.5MBs. The weird part about my situation is when I was using netgear powerline adapters (85Mbs) I would max out at about the same 2.5MBs; hence the wireless upgrade. So I would assume it is a setting I am overlooking. I hope someone can help us out. I will let you know if I find anything.
For Wireless N, it should be possible to get much faster speeds. I'm not a best case for an example....even downloading from the Internet, I'm limited that I have a High Speed Lite package, which maxes out at about 2.5 Mbps anyways.....N is supposed to be able to handle faster than that, but you have to have faster Internet Access to start with.
I tried disabling Remote Differential Compression, but it didn't make a difference.
I've also read online about some other possible fixes..
#2 Log onto machine as administrator, go to command prompt. Run this command:
netsh interface tcp set global chimney=disabled
#3 Log onto machine as administrator, go to command prompt. Run this command:
netsh int tcp set global autotuninglevel=disabled
NOTE: I have not done #2 or #3 yet.....I found those tips on a tech message board, but I don't know the source, and I'm not a programmer or net specialist, so I have no idea what those two commands even do, or how to reverse them if I need to.

Our issues aren't internet speed (which is just fine), it's transferring files from one machine to another using a gigabit switch; the process doesn't use the internet.
A slight addition to the situation.....a few days ago, my Internet speed started becoming very inconsistent...ranging from 2 Mbps down to 0.6. I checked the ISP, and it wasn't them. My laptop was connecting to the router at full speed....so it was something with the desktop.
This led me to wonder about replacing the NIC. Maybe there was a driver problem? Or a hardware failure?
To make a long story short, I replaced the DWA-552 with a Linksys WMP600N. My signal strength *dropped* by 12%. However, the fluctuations in speed became a bit more regular......the ISP was able to increase the speed to 5 Mbps, and with the new card I'm getting anywhere from 3.6 to 4.4 Mbps.
Most importantly, I was reading some tips on other boards, and they suggest that slow speed can be the result of a few things.....including the Linksys software on the disk having a problem with the Windows Network Manager. So I uninstalled the Linksys management software, and just used the raw driver (most recent version). I ran another test, and my file transfer speed over wifi within my network has dramatically improved...it's gone from 200 KB/s to 14 Mbps. Files that were taking 3-4 hours before take about 8-12 minutes now.
So I'm not sure if the problems were with Windows 7's Network Manager conflicting with the Dlink network manager software, if the problem was the Dlink NIC itself, or something else.

As I have said before, if your transfer speeds aren't up to par then upgrading the hardware to something more recent will usually take care of that for you. Some people just don't want to spend money on new hardware and I understand that but sometimes it's the only way. Maybe Fumz will see your post and make a change to his network.
And those so called network managers never seem to work right, I always recommend uninstalling them. Thanks for reporting back in Pleb5919.
