Cisco IP Phones SPA 525G were connected via WIFI and worked perfectly fine. But after changing the router, the phones can not connect to WIFI as they keep displaying "Failed to Associate with SSID, keep trying in the background".
When we add the network, we set it to WPA2 PSK, Profile Name (auto), SSID (auto), Cipher type AES CCMP. It used to work with these settings. But now it won't connect. We have also tried WPA PSK, TKIP with a combination.
The unusual thing is that we have also tried connecting it via ethernet cable and still can not get the phone to work. After resetting the device multiple times we have tried to add the network but are facing similar problems.
When we manually add a wireless connection we see a green bar at the top but the icon next to it has a red cross. However, the mute button is always red.
Can you please help?
