Check the WiFi channel automatically selected by the CPE510. You are running the CPE in Test_Mode, which might use channels outside the frequency band your laptop/cell phone supports.

Also note that using a channel outside those open for public use might attract attention of regulatory authorities if your device causes interferences to other users of the 5 GHz band.

Sir how do I know if my cellphone or laptop supports 5Ghz?

See the verndor's specifications for your devices. You could also check the preferences menu on the cellphone/laptop, check which channels can be set. Note that SOHO devices often support only the 5 GHz indoor frequency band while the CPEs works in the outdoor bands depending on the region/country setting.
