USB 2.0 is 480, USB 1.1 is 12, USB 1.0 is 1.2. ALL Are mega BITS per second not MEGA BYTES per second so you have to divide any number by 8. 54 mega bits per second is theoretical and divided by 8 would be 6.75 Mega BYTES per second. A FRITZ!WLAN USB stick is not a dell product and not supported.

USB WLAN client for wireless networks Wireless LANs in conformance to
802.11n (150 Mbit/s),
802.11g (54 Mbit/s)
802.11b (11 Mbit/s)
USB 2.0 is 480 Mbits
USB 1.1 is 12 Mbits
USB 1.0 is 1.2 Mbits.
Windows without proper CHIPSET and Service Packs will run at USB 1.0 speed on all ports because USB 2.0 REQUIRES Service packs to
WIN2000 or XP.
There are two HUGE sources of confusion and frustration with WiFi networks:
Speed and Signal Level.
WiFi Speed
Marketing experts love to hook you with big impressive numbers “54Mbps”, “300Mbps”, “600Mbps”, and other similar claims are plastered all over WiFi marketing literature and product packaging.
Understand what those numbers are and what they mean for the performance of your network.
What is Mbps?
Wireless network speeds are generally stated in megabits per second (Mbps).
That is a measurement of how fast data (a megabit) can move across the network in a given amount of time (seconds).
A Megabit is one million bits.
A bit is a binary one or zero and those bits make up all of the data within your computer and the internet.
When you look at a file on your computer it’s not generally measured in bits, but in bytes.
Don’t ask me why “they” chose to measure the two differently, but that’s what we get to work with.
So what is a byte? A byte is eight bits. A byte looks like: 10110101
The numbers you see on the product website or packaging is the max air data rate that the system can support, e.g. 54Mbps or 300Mbps.
This rate is not the actual speed that you can move data across the link at!
The air data rate is the combination of:
- Your user data
- Wireless error correction data
- Network protocol overhead
- Wireless communications that allow the AP and clients to get and stay connected
- Space taken up by encryption
- Retransmissions
- And more!
There is a lot more than just your data going over the air.
It’s unfortunate that the manufacturers advertise the air data rate instead of the actual TCP (network protocol) performance.
Here are a few examples of typical max advertised speeds and actual TCP performance:
- 802.11b Advertised: 11Mbps | Actual: 5-6Mbps
- 802.11g or 802.11a Advertised: 54Mbps | Actual: 25-30Mbps
- 802.11n (dual-stream) Advertised: 300Mbps | Actual: 150-160Mbps
- YOU DO NOT GET 300N SPEED on 2.4Ghz adapters.
