Summary: Go wireless in RedHat Linux!
Review: I was a little disappointed when I found that Linksys didn't develop drivers for RedHat Linux, until I found the free ndiswrapper (http://ndiswrapper.sourceforge.net). Install v0.3 in your RedHat 9 and it will allow you to use the WPC54G Windows drivers in Linux! It works great!

Summary: Worked Perfectly
Review: I purchased an all-Linksys G set - a router, PCI card, and card for my laptop. Here is my hardware setup:
Machine 1: WIN 98 First Edition; 400 MHz PII, plenty of RAM; Desktop
Machine 2: WIN 98 First Edition; 233 MHz, moderate RAM; Desktop
Machine 3: WIN 2000; plenty of speed and RAM; Laptop Router:
It is a great product. I hooked it up to Machine 1 and had it running in under 5 minutes and that includes the hardware. I did NOT use the software included - instead I configured the router through the web interface. This is key. The router doesn't even support WIN 98 First Edition according to the min. req. Linksys states. Nevertheless, my setup works flawlessly. In fact, somehow it seems to have increased my Internet speed - something I can't understand, but am more than willing to go with. PCI Adapter:
I am giving this an average 3 star rating because frankly I didn't get it to work but then again it really wasn't supposed to work with WIN 98 First Edition as is running on Machine 2. Now, here's why I feel I should rate this item at all - even if unsupported, loading software and giving it a try should not crash your system and cause errors. In fact, I had high hopes considering the software seemed to load, but in fact it just gummed up the system. So, after quite a while of trying, my poor old system is worse off than before. I just don't understand why Linksys didn't include a way to work on WIN 98 First Edition. At heart this thing is just a bit of hardware and I would think ultimately not much different to the computer than an Ethernet card. I may be wrong, but why can't they design an interface for the older operating system? Anyway, don't bother if you aren't running a newer system. Card for laptop:
Worked like a charm. I popped in the software on Machine 3 running WIN 2000 and in a couple of minutes had a great signal. The laptop was at least 50 feet away from the router and in the basement (router on 1st level). So, through walls and over distance I still had very sufficient signal strength and quality. No dropping was noticed, and the settings were all set for a high level of security. There was absolutely no extra heat as someone noted. Also, no problems working between a hardwired network at work and the wireless at home. Just pop in and out the card is all (I have to because of the tight fit of a a docking station at work). So, overall I'm happy with Linksys.

Summary: Great Product and Stable!
Review: Ok with the software I will say this, This program seemed to have a issue with my setup of my PC, (I Use a Dual Boot System, C: is 98 e: is w2k(main) )
The issue was the software AUTO installed to drive C for some odd reason. In turn after the reboot it came up saying drivers were missing. Long story short, you will have to move the Files from C: to the operating system that you use (Drive wise) and edit the registy to match should it not already, Then WHOOM, all worked fine! Shows signal bars, easy to work with and more. Very well suggested to buy! I gave 5 stars as not many PCs are as complex in issues as mine. ;)

Summary: Very good card
Review: I installed it for a friend in a Dell laptop and it installed in about 2 minutes and had a strong signal from across the house. As far as I know, she hasn't had any problems since. I have not tried to use any of the WEP security features, but it is very easy to initially get online and it seems very reliable.

Summary: Good Card Bad Tech Support
Review: I bought this card because I own the Linksys WRT54G wireless router. The card was easy to install and easy to setup the WEP 128bit. The range on this card is so-so, I've taken my Notebook around the house and it can hold a signal pretty far away from the AP but the signal quality is weak. My only problem with the card is if the notebook goes into sleep mode it turns off, when you bring the PC out of sleep mode the card does not activate and will not reconnect. Linksys has not responded to any of my email's I have sent to them about this problem, the only solution is to reboot.

Summary: Ideal solution, completely unproblematic
Review: With the internal wirelss card that came in my laptop, I had all of the problems cited in other reviews here - heat, dropouts, weak signal, incompatabilities with Norton, etc. Worse, my laptop would routinely connect to my neighbor's wireless LAN (which was secure and so unuseable) but not mind. Then I got the WPC54G, and all of those problems are gone. I now have *two* of these cards running, one in my laptop and one in my wife's. Each took less than ten minutes from opening the box to complete service. Neither of us has ever had a dropout, the signal remains very good to excellent at all times, and we have no laptop heat problems. In fact, this external card runs *cooler* than the internal card, which would keep the laptop fan going to loudly and so strongly that we couldn't hear the TV. Now I can actually operate wirelessly in the den without annoying my wife. :) In reading other reviews here, recognize that many of the problems are *not* due to this laptop adapter. Yes, you may experience some problems under Windows 98. But if you're using a laptop running a six-year-old operating system, you have bigger problems than wireless trouble, and will save yourself plenty of hassles (and time and insecurities) by upgrading to Win2K or XP. Yes, you may have trouble connecting to Netgear's router, but that's because Linksys' router is far superior; get the right router, rather than dissing on this adapter. And yes, if you're unable to distinguish WEP from DNS, you may not be capable of receiving good technical support. I, for one, have nothing but glowing praise for this card, the linksys "g" router, and linksys tech support. Anyone with a contrary experience may well be misattributing to the WPC54G problems that have nothing to do with it.

Summary: An Installation Odyssey
Review: I ordered the Linksys router WRT54G through Amazon, along with its sister PCMCIA card WPC54G for my Gateway Solo laptop. My goal was merely to broadcast the Comcast Digital Cable access throughout my 2,000 square feet home at the faster 802.11g speed. I wanted to surf the Web from the comfy couch in the TV room or a cozy chair in the living room...my choice -- no wires involved. I have never installed a network, so a lot of the literature, reviews on Amazon, and other sources of information were lost on me: I simply went with the big name brand at a reasonable price. I installed the router in about 20 minutes using the accompanying CD. Lights were flashing, and the hard connection to my laptop recognized the router. Flipped up the 5 inch rabbit ears and seemed to be in business. All-in-all pretty seamless. I had high hopes that I'd be wirelessly surfing soon. This was pretty exciting to me, as I am still running on Windows 98SE, and worried that I might encounter difficulties. The installation of the sister WPC54G PCMCIA card didn't go so well. Again, I ran it instruction-by-instruction from the installation CD, and while the Linksys software seemed to install OK, the procedure tripped up when attempting to install a program called 'Odyssey' from a firm called Funk Software, Inc. The program kept looking for drivers, requesting that I insert the Microsoft Windows 98SE disk in my drive. I don't have a Microsoft disk, but a Gateway OEM version that apparently has Microsoft Windows 98SE, but not the specific drivers that Odyssey needs. To sum up, I spent several hours, all told, surfing Microsoft, Linksys, and Funk Software knowledgebase pages, downloading stuff, booting and rebooting my laptop, before giving up and going to bed frustrated. Tried again in the morning, and somehow, I still don't know how, hit the right combination of set up protocols that suddenly energized the PCMCIA card. I went from zero to eighty in no time, and my profanities turned to whoops of joy. The best online help came from Funk Software, where I found a customer service technician at the help desk who answered my emails. His solution: as I was running a simple home office network (not a corporate enterprise solution) and I didn't employ a RADIUS server (whatever that is?) I shouldn't need Odyssey, so gave me good instructions on how to eradicate it from my PC. Still not entirely sure what Odyssey purports to do, so perhaps I'm missing some benefit? Nonetheless, the router and card in my laptop are communicating nicely throughout the house...no connections further than 3 walls and 150 feet. Speed is excellent. I stepped through the setup of what I suppose is a rudimentary firewall (clicked a box marked 'Firewall enabled') and turned on WEP 128. I hope to figure out WPA next, and I hope that Odyssey is not part of this set up, but in the final analysis I am pleased with the product, happy I didn't have to pay a consultant, and sending this report to Amazon wirelessly from my comfy chair! Experience of user: None.
Total install time: 5 hours
Biggest problem: Firmware for WPC54G card missing drivers for Win98SE.
Observation: If TVs had come with this infernal alphabet soup of protocols (WEP, DHCP, DNS, IP, etc.) we'd all still be listening to family radio hours!

Summary: Excellent product
Review: I second mike_spike's opinion. This is a great product. Two of us colleagues have bought this, and it works without problems...On an average, I get 48.0 mbps connection with my wireless WRT54G linksys routter...I have used this for nearly a month now, without any incidents of dropouts... Also, I tried connecting to another of my colleagues' Netgear wireless network, and I was able to connect in no time. the card just recognized that a "Netgear" wireless connection was available(though his WEP may not have been set)..... Great product, though Linksys really sucks at Technical Support...

Summary: NO LINUX SUPPORT
Review: This card works great with Windows 2000 and a D-Link 802.11g Wireless Access Point. My major complaint is that Linksys has stopped providing the specs for their chipsets as of the 802.11g series. The 802.11b series cards work great with Linux/*NIX, but the 802.11g does not and will not work at all. Apparently the company Linksys chose for the chipset, Broadcom [www.broadcom.com] refuses to release the specs so no one can write drivers without months of experimentation and reverse-engineering. I have always found that devices that do not provide linux support are inferior in quality and reliability to other devices that do.

Summary: This is a joke
Review: If you are using Windows 98, dont even think of buying this product. It updates an existing dll file to an incompatible version, and applications such as Norton Internet Security become unusable. Their support web page is inaccesible, and their 800 support number disconnects you once you press the numbers that lead to that product's support area. Bizarre, to say the least.
