Summary: if you need wifi In another location and don't want to use range extenders this is for you.
Pros: wow this thing is great! my router was in my main house. I ive in the house we have in the back. ran 100 feet of cat 6 from my router to this device now I have wifi for all my devices. install and setup was a breeze maybe 10 min after running the cat 6.
Cons: none.. I cant believe it either, works as advertised.
Pros: None. I can't think of anything good to say about this piece of equipement
Cons: I went through configuration nightmare that is mentioned in several reviews and in the press. Once it was up an running it was completely unreliable and worse it would lock up the switch that it was connected to after a 3-4 hours. I reset it a bunch of times. Upgraded the firmware. I was even going to downgrade the firmware but the thing won't even reset to factory anymore. Its about 3 days old and maybe worked a total of 6 hours. I spent at least 3 hours just trying ...
Pros: Push button configuration with my DIR-655, seems to maintain a connection from day-to-day unlike the DAP-1522 that it replaced.
Cons: There's a weird glitch when you select the Wireless Settings page in the setup... you see it flash up all the settings momentarily, then see only a minimal set of options. This prevents you from making any changes to the wireless settings, but maybe that's due to the push-button configuration.
Summary: Mine came with factory firmware (flash code) that was buggy. v1. the AP lamp (to LED) was dead. so was the wifi transmitter. 2.4g-AP , had problems. I flashed it to 1.02.bin level and the unit works far better than my dreams. Always flash routers ,the first thing. (for many reasons besides security) keep it up do date too. Dlink see links below. The steps can be complex, due to the many application, configurations."vast" get the wired network working first.
Excerpt: For 3-4 years had DAP-1522 as WAP + 4-port switch in upstairs gameroom ... just died one day. Was about to replace it, but D-Link now has DAP-1525, and after reading a few online reviews, bought it @lowest price, from B&H... arrived a few days later (fast!). Followed CD instructions and had connected to network and Wi-Fi working in ~30 minutes. Kids say WiFI now faster than before on notebooks and smartphones. We're all happy!
