What's the maximum transfer speed you get, (or I can get) for files transfer between two wifi-connected computers ?
Im on computer A trying to copy a big file from computer B, they are side by side (on adhoc network) and I can't get more than 800 KB transfer rate.
Both adapters have relatively the same configuration:
- Wireless mode set to IEE 802.11g
- QoS (Quality of Service) enabled
- Power output set to 100%
- Rate set to 54
- some enhancements like Xpress mode, Optimize brandwith are enabled (and they don't make changes)
- Other settings set to defaults
Is that normal ? if so, what does 54 Mb/s mean ? I should ask : how to get my ~7Mb ?
PS: the computer B Wifi adapter is a USB RTL8187 Wifi adapter.
Best Answer
Unless the computers are connected by an ad-hoc wireless network, it is the distance between the computer and the access point that is important.
54 Mbps is a theoretical throughput, which is roughly equivalent to 6,75MB/s. So you can expect up to 6,75MB/s as network bandwidth.
But when you are transferring files, the bandwidth is not fully used for transfer because of:
At the end, the best you can expect is around 4MB/s in real transfer rate with a light protocol (like HTTP).
