Sounds like an older AP to me.

The best way to check this is with a wireless sniffer and analyse WLAN


But you have to be familiar with WLAN protocol. Alternatively you can
upload the capture to a webserver, send the link to this mailing list
and I can take a look.

(I don't generally give private support, I only answer questions in
public mailing lists.)

There's no easy solution with 770, sorry. And besides, if you disable
WLAN Power Save Mode the battery will run out within few hours.

I would recommend trying with another AP first. Most of the APs
support WLAN Power Save Mode properly.
