Pros: Got it at a good sale price luckily.
The web management interface has a lot of granularity and features. Especially compared to the 8 year old Buffalo it replaced.

Cons: Just unreliable. The 5ghz network just disappears sometimes; the concurrent feature is a joke. Just recently the router basically STOPPED working entirely until I upgraded the firmware. Would not route outside my internal network. The new firmware increased the range of the wireless just a little bit. And brought back the 5ghz SSID which again, vanished for no reason. Constantly logging into it to reboot it because the internet is slow and it always seems to get better after the reboot. I think it has some internal memory issues. Memory overflow or not clearing/allocating properly. Just a guess, but would explain some of my issues.
Sad I have to consider flashing third party software on it after only 5 months.

Overall, not a simple/reliable purchase.

Other Thoughts: I'm a certified IT personnel, so I understand all the features in the web interface and how to set them up. I wish this router was a reliable option, because it has a good feature set for the price and would be nice to recommend to clients.
Certainly won't be recommending this. Infact if it decides to outright STOP working again I'm going to contact TP-LINK. Or experiment with flashing OpenWRT on it and see if I can save it from being a paperweight.

Pros: None, never worked. Can't wait to upgrade mobo for native 3.0!

Cons: It never worked when I got it. I gave up on it and just settled for native 2.0 ports for my WD 2tb backup drive. Recently tried to get this card to work again because I want to redo my entire back up (~800GB!!!), but still worthless. Thought maybe they would have released new drivers/firmware by now. Tried their drivers along with the automatic Windows Driver installation, multiple clean installs. No change.

Tried firmware update, error with "Could not find device".

Other Thoughts: EVGA x58 Triple SLi main, Windows 7 Pro 64bit
