Fast * stable wifi connectivity * fairly discrete in the PC build
Driver software is clunky * larger antennae would have been nice
Just an all-around solid WiFi PCI-e card, not much more to say really. I'd suggest against installing any driver software from the CD, just let Windows install the barebone drivers for it to work, and forget about it.

Experience: 15 Months
Works fine with Windows Vista and Windows 7.
Did not work with Windows XP with VIA chipset.
I got this to upgrade an old 802.11b/g card to work with 802.11n wireless.

I could not get it to work in an older Windows XP computer. I contacted Trendnet technical support and after trying a few things they offered me an RMA. I didn't go for this since it worked fine in my other computer that had Windows Vista installed. I suspected that there may have been a driver problem or a compatibility problem with the motherboard chipset (VIA PT880).

~Large range
~Easy setup
~Could be faster
I got this on sale and I'm pretty happy with it so far. I'm not sure why some people are having so much trouble setting this up. I installed this without following the instructions (by accident) and it works fine (on my windows 7 x64). The only problem might be that the windows will not automatically connect to it when you logon but that is easily fixed by creating a profile in the utility/driver that was included in the CD.

Decent Reception
Good Price
none yet
Works well so far. Gets decent range, and hasn't dropped the connection yet. Average speed. Simple to setup on windoze 7.

FAST! FAST! FAST! easy to install. Very inexpensive, especially on sale.
none in any way
This card is VERY good. It is extremely fast, with an incredibly noticable improvement over the DLINK Rangebooster G USB I have been using before it.
I have been impressed with Trendnet since my first purchase of the mini USB network adapter about a year ago that was unfortunately smashed accidentally. I will certainly buy this brand in the future as my now preference.

This card ROCKS!

Easy to install
Doesn't auto connect to network
For the price that I got this (15$) this was a pretty good buy. Installation was easy and it was generally a good experience. The actual performance was a bit less than I hoped for. For some reason, I only get 4 bars when I am in the same room as the router. Another problem was that when I reboot or let it go into sleep mode, it wouldn't auto connect to the network. A few problems but I can live with them, after all, it was only 15$.

Pas cher en solde à 19.99.
Détecté par windows 7 (pas besoin d'installé manuellement le pilote).
Bonne porté.
Compatible IEEE 802.11 N.
Rien à signaler.
J'ai acheté cette carte PCI sans fil pour un collègue qui n'a pas de réseau câblé dans sa maison. Il me rapporte que la porté est très bonne et que le signal reste toujours fort quelque soit la localisation de son ordinateur dans sa maison. Aucun besoin d'installer un pilote manuellement avec Windows 7 64 bit parce que ce dernier l'installe automatiquement. Un bon achat surtout lorsque cette carte est en solde à 19.99$.

Ya, its alright
works as it should
for 20.00, you can't go wrong
A bit of a challenge to install, but once there its alright.
Install was a bit of a pain. Speeds are quite acceptable.
Presently working very nicely in a customers computer.

no driver installation, no issues, N compatible
two bulky antennas
This works great on both windows 7 64 and 32 bit. The dual antennas are bulky but you can always remove one of them.
