@Kevin_Z actually I made some tests on my ps3 and it indicates the router dont support packets fragmentation and I went test to use the ps3 with the pppoe connection on it and dont worked. Tested on ap mode too and not worked too.
On my previous wa901nd this worked fine. Both the ppoe connection on ps3 and on my notebook. But the normal mode that I use is the router connected by pppoe on adsl modem.
On access point mode the device should be transparent. There is no reasons to this not working. This router is very annoying.
