Terrible Customer Support

Pros: None

Cons: Causes both of my systems to freeze. After two weeks of RMAs and customer support call backs, I'm fed up with their customer support. First of all, you can't call customer support, you can request somebody call you then wait 2-3 days... heaven forbid you need to talk to two people, then it turns in to 4-6 days.

As it stands now, their verdict is that the card's drivers do not support Windows XP SP2 or SP3. Or Vista. Or Mac OS-X. Or Linus. I guess it might work on Windows NT? I don't even know, he couldn't tell me what OS was supported.

Other Thoughts: Never touching another 3com product, waiting 2 weeks for support is a joke.

Excellent Card Overall

Pros: Range, stability, quality of connection all excellent. Never had dropped packets as a result of the card. Works great for Linux, native support. Also a great gaming wireless card.

Cons: No wireless N support.

Other Thoughts: Works great in Vista x64. I use it in XP, Vista x64 and Ubuntu in a triple-boot setup all without a hitch. If you are using the card in Vista x64, use the Atheros chipset drivers.

Takes some tweaking

Pros: Great connection once you get it working, or in 32bit Windows and any flavor of Linux.

Cons: Support for 64 bit is abysmal -Except in Linux
Drivers are unsupported.

Other Thoughts: I bought this card back in November of '07 after reading reviews on how great it was. Unfortunately when I tried to load it in x64 Vista I found out it was unsupported by 3COM. However it's chipset is Atheros 5414, and those drivers work great. you can get them at www.atheros.cz, so if you are running x64 windows save yourself the headache and get the drivers there.

Awesome Linux card

Pros: Easy installation. Despite previous reviewer saying "doesn't work in 64 bit OS" I'm using 5 of these in Ubuntu 64 bit Linux desktops with great results. Maybe the correct answer is "doesn't work in 64 bit Windows OS" but I wouldn't know because I don't run Windows :-)

Cons: Pricey, but you get what you pay for.

XP Performance-TERRIBLE

Pros: Hardware seems solid.
Comes with half height bracket.
Nice antenna included.

Cons: XP Driver-NOT UPDATED IN 3 YEARS
Pricey

Other Thoughts: Purchased 12 of these cards for an XP business deployment. Intermittent connection problems in XP. If I boot the same machine to another OS (Linux) the card is rock solid. Contacted 3com for newer drivers (driver on CD and web site is from 2005!!) and was told that no updated XP driver would ever be available for this card, as they are 'phasing it out'. To sell a card new in 2008 (at a premium, no less) and refuse to update the driver for the most widely used OS is simply unacceptable. Note: I am not speaking to the cards' performance under other operating systems, just XP. No more 3com products for me.

Newegg shipped on time and did a great job as always.

Seem to work great!

Pros: Fast, small, easy to install and most importantly it works GREAT!

Cons: None so far other than cost...

Other Thoughts: Just got it today... I tried a different cheaper card and it wouldn't hold up with online computer games, kept dropping packets... So I looked around and thought this looked good... It is expensive but you get what you pay for. Well worth the money to have a working wireless connection.
Very good buy, would easily recommend.
