1 out of 5 eggsboydg1

Pros: This is the 2nd recount of my experience with this "AC600 Dual Band Wireless USB Adapter". (1st recount 1-2-2014)
First unit was shipped back to TRENDnet after installing it on a second computer with similar results and a replacement was returned and the following step by step evaluation was made as follows:

Cons: 1.) Plugged in the Adapter ( computer).
2.) Ran the software.
3.) Clicked on the icon.
4.) Only the 100% signals came up (SSID's).
5.) Opened the software and inputted an SSID and Key and to my surprise came up with a 64% signal.
6.) Updated the virus program, Lost connection momentarily and continued the update.
7.) Virus update FAILED, lost connection, regained connection. Restarted virus update now at 15%.
8.) Lost connection again. Canceled virus update.
9.) Now, limited connection (No Internet) Two bars on the WiFi scale.
10.) Disconnected USB connection at computer and reinserted, reestablished connection immediately.
11.) Started FireFox - after well over 4 minutes, still NOT fully connected but did NOT loose internet connection.
12.) ENDED TEST and CONCLUSION: Even though this unit held the internet better than the first unit, it still does NOT have the necessary throwput.
After this, installed ROSEWILL RNX_N250UBE (now becoming my Gold Standard) under the same conditions. FireFox came right up and the virus program updated itself normally.
NOTE: In comparison, connection percentages were higher with TRENDnet, in the 60% range, and with ROSEWILL in the teens to low 40's percentages.

Pros: Trendnet TEW-804UB review
A Recount of my experience with this "AC600 Dual Band Wireless USB Adapter".
1.) Quick install, and Fast, came right up.

Cons: 2.) Downloaded E-mail and could NOT Forward. No Throw-Put. Quick Response dialog box, was: Timed Out.
3.) Reinstalled a number of times with difficulty. Had to manually click on Windows WiFi icon and TRENDNET WiFi Icon to select WiFi signal, No Default Choice, every time I rebooted to get any responses at all.
4.) Cleaned the system of all clutter and reinstalled, three - four times. Downloaded same version of software from TRENDNET web site, thinking that there just might be a difference, Eventually the Adapter would NOT receive OR send at all. ( struggling with this and dissatisfied. Uninstalled the software.)
5.)Reinstalled ROSEWILL RNX-N250UBE Adapter, came right up, even gained ONE bar on the WiFi scale, probably because I cleaned all the clutter out, and now all is well once again with the WiFi on this Computer. This has been my experience with this Adapter. I had expected a whole lot BETTER of TRENDNET.

Manufacturer Response:

Hi Anonymous,

I apologize deeply for this unpleasant experience with this adapter. Before replacing your unit, if possible, I would suggest to try this adapter on a different computer. If this still doesn’t help please email me at with "Newegg TEW-804ub Review" in the subject line and I will contact you immediately to go through a hassle free return. I look forward to your reply soon.

Warm regards,

4 out of 5 eggsgreat... when it works

Pros: Small. inexpensive, connects easily, with good reception.

Cons: Drops signal and requires reset.

Other Thoughts: This replaced a Rosewill RNX-N300 IEEE 802.11b/g/n Wireless-N 2.0 PC, gets better reception, and was cheaper.
Once a week, however, it requires troubleshooting and eventual reset.
