I have two machines, both running Windows 7 x64. Transfer rates across the network are at most 1.4MB/sec. Here is my setup: Machine 1 - Windows 7 Ultimate x64, Norton Antivirus, Windows Firewall, Airlink101 300N 6090 PCI Adapter (latest driver from manufactures website), 2 internal HDD Seagate 320GB @ 7200RPM Machine 2 - Windows 7 Professional x64, Microsoft Security Essentials, Windows Firewall, Marvell Yukon 88E8053 Gigabit Network controller (latest driver from manufactures website), 1 internal 250GB seagate @ 7200RPM, 1 internal 320GB seagate @ 7200RPM, 1 external USB connected 1.5TB seagate @7200RPM Connected by Airlink101 300N AR690W Gigabit router Here is what I have tried: IPv6 - Disabled RDC - Disabled Local transfer rates between different HDDs on same machine about 50MB/sec (both machine 1 and 2), the external USB connected 1.5GB drive transfer rate 50MB/sec when transferring files locally Network transfer rate with Windows Firewall OFF - 1.3MB/sec average Settings for Marvell Yukon gigabit adapter - Full duplex Settings for Airlink101 300N adapter - no duplex selection available Settings for Airlink101 300N AR690W Router - "Mixed Mode B/G/N" or "N Only" did not effect transfer rates All machines are assigned locally static IP addresses Speedtest.net 10Mb down, 1Mb up, ping 16ms Ping test to router from each machine 1-2ms. It seems I have read every form on the net about this problem and tried every fix/workaround. Hard wiring Machine 1 to the network is a last resort, I should be able to get better than 1MB/sec out of the setup I have. Hopefully someone out there has the magical answer.

Since you do not have a Windows Home Server machine involved, your thread is off topic here and should be posted in one of the Windows 7 forums. This being said: network performance issues are difficult to troubleshoot. They can be caused by software (network card drivers and their configuration - i.e. stuff like Jumbo packets, name resolution, router firmware, virus scanners, malware ...) or hardware (router, switch, network cables and plugs. Its the slowest member of the entire chain, which determines the final speed. Best greetings from Germany Olaf

Does your laptop find a lot of strong wireless connections besides your router, when you view available connections? 3. have you tried switching the channel on the router? (this is in case you have other strong signals in #2) 4. Have you tried hard-wiring Machine 1 just to rule out wireless interference? Reasoning: If you hard-wire it, and you get higher transfer speeds, then you know that it's wireless signal interference or something affecting your wireless. However, if the transfer speeds are the same, then it's something with your network itself or Windows. If you can get a crossover cable, and directly wire the two computers together with it to check your transfer speeds, that will tell you if it's the router, the cables, or one (or both) of the computers. Something else to note (although this may not apply to you): If you're referring to download speeds from an external site, then 1.4MB/s is about right (or higher). The reason for that is, you're converting from a system that treats 1,000,000 bits as 1 million to a system where it treats 8,388,608 Bits as 1 million. (Base 10 for megabits to Base 8 for megabytes) So, you would have to take your 10,000,000 and divide it by 8 to get bytes. Then you take that number divided by 1048576 to get it into megabytes. Which gives you a max of 1.19MB/s (you may have to take this number by .85 to get a more accurate measurement because you may lose about 15% of your download speed to overhead). Sorry for the networking lesson. It's more aimed for the person who says "I have a 10mbps Internet connection, but am only downloading at 1.19 MB/s. Why???" In your case, you should be seeing more like 119 MB/s (roughly). It appears that for some reason you're only going at a 10mb/s connection speed instead of 1gb/s. Which is why I suggested testing it with everything hard-wired to rule out wireless interference. Hope this helps, and have a great day:) Patrick. -- Smile... Someone out there cares deeply for you.
