Not only it, but almost all DSL- xxxT family comes with Texas Instrument cpu TNETD7300GDU AR7W MIPS, I wonder if that chip can really manages up to 64 wi-fi clients + 4 switch ports and the adsl connection itself. It must be quite a waste for using this fantastic cpu on DSL-502T since it doesn't need to manage wifi or do qos its amazing power will not really be used there, cmon give me a break.
Now the good news, at least from the software side, it is possible to flash the router with version 3.0 of the firmware which was supposed to only work on DSL-G624T, but guess what, it has almost the same piece of shit hardware so it works flawless on DSL-G604T. DSL-G624T 3.x firmware
After one week using the new firmware it seems much more stable than the previous, it happens to improved adsl signal so no disconnection or modem getting out of sync, much faster wi-fi assossiation and no single thing to complain up to now.
