Scenario
My Netgear 54Mbps 802.11b/g usb wifi dongle has joined the broken list recently. I am aware that Wireless PCI network card is a clear winner for desktop computer (compare to usb dongle). It uses less processor cycle and faster.However, I opted for the Usb dongle instead. The reason is I have 2 desktop computers. I can swap it to another computer. Imagine unplugging the wireless PCI adapter card.....
How do you know which Usb dongle works with Windows 7? Does it support 32 bits or 64?
Find out the answer from Microsoft official Windows 7 Certified Usb Wireless adapter Compatibility page.The logo indicates:
"We focused on robust testing requirements to ensure optimal Windows 7
experience. Products that receive the Logo are checked for common issues
to minimize the number of crashes, hangs, and reboots experienced by the user."
I end up buying the following from Amazon. Apparently many good reviews.
Edimax EW-7811Un Network adapter
What to consider when buying a new wireless USB adpater?
1. Security/Encryption
Avoid WEP as it's less secure wireless protocol (exists in the older version of wifi adapter). Look for WPA, WPA2/AES.
2. Network compatability (802.11a/b/g/n)
Does the dongle need to be backward compatible with specific 802.11b router? Or do you intend to use the dongle to connect to other 802.11x router? If you only have one 802.11n router, just get the dongle that support 802.11n.3. Draft version
Watch out for 802.11n or draft 802.11n. Avoid draft version by checking manufacture specification.
4. USB compatibility. USB1.0, 1.1, 2.0 or 3.0.
Which version does your desktop computer supports?
5. Software set up.
Does the dongle software allows you to save configuration profile?
6. Range.
New usb dongle has MIMO technology that increase range, realiability and speed. Dearer indeed. 7. Issues. Check online forum whether it has overheating or battery draining issue (if use on old laptop).
I hope you find this post useful. :)
