To see if replacing the stock antennas with the ANT24-0230 makes a difference to the signal strength, we mounted the antenna on the wall and pointed them downstairs.

D-Link ANT24-0230 Xtreme N 2.4GHz Antenna Review 

After rebooting the router and the laptop, which was an ASUS U1F, we observed the signal meter on the Windows Vista utility to see if it made any difference. Before adding on the antenna, we got three out of five signal bars. After adding the antenna, we got…three out of five signal bars. So in terms of performance, it doesn’t seem to be doing anything noticeable.  But then again, D-Link never said it would. We did try moving it around, pointing the antennas upwards, to the left, to the right, and it didn’t seem to make any difference.

Final Thoughts

 D-Link ANT24-0230 Xtreme N 2.4GHz Antenna Review

D-Link never claimed a signal strength increase by adding this antenna on to any of the supported routers like our DIR-655 Xtreme N router.  We verified that it really didn’t do a whole lot to “amplify” the signal strength, at least not according to our Vista Wireless utility and our ASUS U1F’s built in WiFi network card. That means that if you’re in a sketchy area of the house for signal, it will probably still remain…sketchy. What it does do is add 1.16 meters of cabling between the antenna and the router, providing you with extra options in which to place your router. For instance, if you wanted to lock the router in an equipment closet, you could route the antenna outside the closet to ensure that you get the best possible signal.

Overall, at around $30 bucks to get in the game, I can think of a lot of other things that I could spend my cash on.  Though it didn’t seem to improve the signal strength performance noticeably, it might help a desktop adapter more by getting the antenna out from under a desk.  Based on the performance aspect, I guess this is the reason why I see so many of these sorts of products sold as “Open Box” products at the local big box stores.


  • Allows you to place your router in a better spot to hopefully maximize signal strength
  • Compatible with certain desktop adapters, allowing you to move the antennas from under the table


  • Doesn’t provide a noticeable increase to signal quality in our testing
  • It costs $30 bucks to get in the game

Overall Rating: 6.0 / 10.0
