How do I find out about firmware upgrades?
All new firmware upgrades are posted on the Web. To download the latest firmware, go to the Dell support website:
support.dell.com.
NOTE: You can only use firmware designed specifically for the Dell Wireless 4350 Small Network Access Point.
Use the Upgrade Firmware page on the web-based configuration tool once you have downloaded the firmware. Click the System
Tools tab, and then click the Upgrade Firmware option. Enter the file name and path for the new firmware. Click the Start button
to load the file on your Dell Wireless 4350 Small Network Access Point.
What is the actual speed throughput for the Dell Wireless 4350 Small Network Access Point ?
In 802.11g, wireless network adapters and access points provide up to 54 Mbps data transmission rate. In 802.11b, the data can
be transmitted at the rate up to 11 Mbps. Actual throughput, however, may be less, just as 10 Mbps-cabled Ethernet does not
always provide 10 Mbps performance. Transmission speeds vary with files size, number of users, and distance from the access
point. A properly designed system provides Ethernet-like performance for users. As signal strength decreases, the automatic data
rate of 802.11g decreases from 54 Mbps to 48, 36, 24, 18, 12, 9, or 6 Mbps in order to maintain the connection. The data rate of
802.11b may decrease from 11 Mbps to 5.5, 2, or 1 Mbps.
Are there any known health issues caused by Radio Frequency (RF) transmission from the Dell
Wireless 4350 Small Network Access Point?
There is no conclusive evidence, to date, that RF waves from the 2.4 gigahertz (GHz) range pose any health issues. Although
wireless LAN devices operate at the same frequency as microwave ovens, wireless access points and adapters at 2.4 GHz emit a
power signal of 100 milliwatts (mW), less than other 2.4 GHz products, such as microwave ovens or cordless phones.
Is this a shared or switched technology medium?
The wireless access point of the Dell Wireless 4350 Small Network Access Point is similar to a hub, which is a shared medium.
What is the difference between Bluetooth™ and 802.11?
These technologies are aimed at different situations. Bluetooth is a 1 Mbps technology designed for the interconnection of devices
that are in close proximity to one another. You use Bluetooth when you have two or more devices requiring direct connectivity in
short distances of about 30 feet. Some examples include PDAs or handheld computers to computers; notebooks to printers; and
phones to headsets. The 802.11 products are a full LAN connectivity solution, designed to provide network transmissions at high
data rates and at a greater distance. You use 802.11 products when you want to access the Internet or a local area network.
Does the Dell Wireless 4350 Small Network Access Point prevent hacker attacks?
The Dell Wireless 4350 Small Network Access Point attempts to prevent unauthorized access by restricting permissions to
specified users on your wireless network.
The web-based configuration tool also contains an intruder detection log which records any attempted break-ins by unidentified
users. To view the log, start the web-based configuration tool. Click the System Tools tab, and then click the Intruder Detection
Log option.
