Belkin Wireless USB Adapter - 3.5Mbps maximum for file transfering

[ub4me]

I have a D-Link 614+ wireless router and 650+ cardbus adapter for my notebook.
For my desktop, I used cat5e until I recently bought this Belkin USB wireless adapter (F5D6050).
However, I noticed that Belkin adapter's maximum file transfer speed is 3.5Mbps (not 11Mbps) while D-link 650+ scored 8Mbps.

Why Belkin USB adapter is much slower than D-link 650+?
Is it due to USB1.1? Or it doesn't have 22Mbps technology of D-link's?

If I returne Belkin USB adapter, what is the best to achieve more than 8Mbps barrier?
1. Belkin Wireless Desktop PCI Network Card (F5D6001)
2. D-link DWL-120+ Wireless USB Adapter
3. D-link DWL-520+ Wireless PCI Adapter

Thanks ahead!

u have the answer...

actual speed is whatever advertised speed x ~ 0.35

> I noticed that Belkin adapter's maximum file transfer speed is 3.5Mbps

sounds right to me.

Yes, when the 614+ and the 650+ are used together you will have a maximum of 22mbps, but when a standard 802.11b device is used it will only be able to run at 11mbps.

Wireless Ethernet needs additional protocol over head for the transfer. In addtion, it is not as stable as Wired so it needs extra processing procedures.

As a result the 11Mb/sec. of the Network chipset is translated to much lower actual performance. Usually 4-6Mb/sec.

3.5Mb/sec. is on the low side but close to the normal range of Entry Level Wireless.

The So called 22Mb/sec. is nice, but in real term will yield only 20% more than 11Mb/sec. systems.

The 802.11g line that is rated 55Mb/sec. yields 18-22Mb/sec.
