Cisco-Linksys WPC55AG Dual-Band Wireless A+G Notebook Adapter Review

Average Reviews:

(More customer reviews)I have a Linksys WRT54G wireless G router and I have tried it with 2 card offerings from Linksys - the WPC54G (for 802.11 b/g) and the WPC55AG (for 802.11 a/b/g). I can honestly say that with my router (w/ latest firmware version 1.02.1) I have had very strong streaming connection w/ the WPC54G card, not so with the WPC55AG. Using the a/b/g WPC55AG, the connection was significantly weaker and I would lose connection at the same distance. My desk is about 20 paces away from the router as the crow flies, (ie: other end of the 2 bedroom condo). Here is a pic of the 2 cards side by side: http://....
In conclusion, I would NOT recommend the linksys WPC55AG card if you DO NOT have to connect to a 802.11a wireless network.
I have not had to connect to a 802.11a wireless network so I cannot comment on this card's connection ability in a 5GHz network. Secondly, wireless 802.11a networks are quite rare. If you only have a Linksys WRT54G, then stick with the WPC54G card.
I purchased the Linksys WPC54G laptop card and WRT54G wireless 4 port router on Amazon for $...(UPS ground shipping included).
I purchased the Linksys WPC55AG laptop card for $...(SHIPPING included) on ....com. Their price unfortunately has since gone up ($...), but I was happy w/ their service. I received the product 5 days later via FEDEX.
Look up WPC55AG on http://www.....com for the best deal. Enter your ZIP to see the bottom line price including shipping.
One last tidbit, you could always go to Best Buy and purchase both cards to test them out for yourself. You are allowed to return the product withing 14 days. CompUSA will also probably have the product but imposes a restocking fee :(
Hope this was helpful.

The Linksys Dual-Band Wireless A+G notebook adapter lets your notebook communicate with all three wireless network standards: 802.11b, 802.11a, and 802.11g. Typical 802.11b networks have a data rate of 11 Mbps, and are commonly found in corporate environments and in homes for household Internet connectivity without the need for running cables. They're also popping up all over the country in coffee shops, airports, hotels, convention centers, and other public spaces offering Internet "hot spots" to mobile users.
In high-speed or heavy-usage environments, 802.11b is quickly being replaced by 802.11g, which uses the same 2.4 GHz radio band, but at 54 Mbps--almost five times faster. The third wireless network standard is 802.11a, which also runs at 54 Mbps, but operates in the less-crowded 5 GHz radio band. Corporations are the most common user of 802.11a networks.
Whichever standard you use, the Dual-Band Wireless A+G notebook adapter is ready to connect. And it's simple to use. Just pop it into a PC Card slot and run the included Setup Wizard, which will walk you through the configuration. All wireless communications can be protected by up to 152-bit encryption, so your data stays secure.

D-Link DI-784 Wireless Cable/DSL Router, 802.11a/802.11g, 108Mbps Review

Average Reviews:

(More customer reviews)
As several others here, and elsewhere, have reported - the unit worked fine (great actually) for several months, then started locking up. All LED's lit - reboot and all is ok. Does it once or twice a day, sometimes more often. If I leave for a few days, it will surely be locked up when I return. Have updated to the latest 2.40 firmware - no help.

Ap 541N Wireless Access Point Review

Average Reviews:

(More customer reviews)Cisco had a lot of bugs with early firmware, since this is their first Linux based access point. However, if you run their latest firmware (1.9 as of this writing), the device is rock solid. I replaced some older 2.4GHz-only access points with the AP541N, and so far, it's been great. I'm running this in 5.0GHz mode (802.11a/n) due to local interference on the 2.4GHz band. Note that this access point, while claiming to be dual-band, has only one radio. This means that it can only operate one of the frequencies at any given time, so you can run it in 2.4GHz mode *or* 5.0GHz mode, not both concurrently. If you still have older 2.4GHz clients (802.11b/g), you will need to either run this AP in 2.4GHz mode, or run a second AP to support the second frequency.
For advanced users, this device has a couple neat features. First, it can run a number of SSIDs concurrently, each with different security models, and associate them with VLAN tags. On our network, that enables us to run a "Guest" network with limited access to resources, along side our "Internal" network. It can also replicate it's config to multiple AP541N access points within the same network, enabling you to manage them as a single mesh, without having to purchase the complex (and much more expensive) managed wireless infrastructures. FInally, it runs the Linux OS on a Cavium MIPS CPU, and has a full SSH daemon and busybox shell environment, so I'm sure there's some creative modifications that an advanced user could run on this access point.

Cisco-Linksys WRT55AG Dual-Band Wireless A+G Access Point + Cable/DSL Router with 4-Port 10/100 Switch Review

Average Reviews:

(More customer reviews)This product is rushed to the market but not yet ready for prime time.
Issues:
1) If you are using VPN to access your companies network - forget it, this product won't allow you to connect (will not pass IPSec-L2TP or PPTP traffic through)
2) WEP encryption doesn't work - yes, you can enable it but after 3 min you will loose connectivity with you wireless network. With WEP disabled connectivity will stay up.
3) MAC filtering doesn't work also - the router will reset back to default (Disabled) setting as soon as you submit changes to it.
4) Changing Internet Filters setting will reset this router to factory default.
5) Firewall is also not performing well.
6) Tech support is "dancing" and you won't give you any type of answer when they will come up with firmware upgrade - they won't allow you to talk to a supervisor also - USELESS.
On my scale from 1 to 5 this product gets 1.5.
