frequency question

Hello

I’ve got a groove ar9300. My services provider frequency is now 2337kHz. I was connected to him for a month then it died and now I can’t connect or even see his ssid in My sight survey. He says the frequency has not changed and he has 250 other clients all using ar9300 and they are connected. What can I do to connect or what am I doing wrong? I can only see ssid’s in the 24** range. Thanks for help.

Your are using a new Groove now?

I think Young have to set the Scan List in configuration and Order set the device to superchannel Mode
