Since I installed my CRS125-24G-1S-2HnD I’ve been experiencing severe wireless performance and availability degradation, something I didn’t have before this router, when using my Apple Airport Express. The wireless network was fine in the areas around the room where the router is installed, but more then 15 meters away, in further rooms or in the backyard, in spite of the strong signal and no interference, the connection would drop and would not reconnect. It is funny that, if I tried to reconnect, the iPhone would request for the WPA2 password, as it didn’t have it.
Here some screenshots of wireless analyzers and the phone asking for the password when trying to reconnect:
These are a few logs found on the router:

I had searched on the forum and on the internet and could not find any fix information that would help me fix my problem. Today I started working on it again, and although my macbook was not being impacted by this problem, I ran the wireless analyzer on it, which gave me a warning regarding country code that really called my attention:
“This may prevent your Mac from automatically re-joining a previously joined Wi-Fi network.”
After seeing this message on my macbook I changed the configuration on the router from “no_country_code” to “Brazil” on the wireless card configuration and I could experience high performance and long range. I changed back to “no_country_code” and rebooted the router, and the problem appeared again. Changed to “Brazil” again and the problem was fixed again. Throughput above 100Mbps and great working range.
One could say: “You should have configured that since the beginning” but I had never configured that in my previous APs, and everything was OK. Now I can turn my Airport Express off or move it to some other place to extend the range even longer.
Hope that helps…
Best regards.
