A little update on my DIR 655 router
I spent almost a year with dropped connection, updating new firmwares trying new beta versions, taking off DNS, firewall, no password, password, mac address..etc doing everything possible to it because I do not like to throw away things.
But this time I just bought a brand new ### ( I am not here to advertised the competition)
and that fixed my connection problems !!!
the DIR 655 is in the recycling bin outside in the cold, sorry buddy
I can finally enjoy my internet !
ps:
Thanks to all the people who tried to help me, you are the lucky owners of a working D-LINK router so hold on to it and never update or change anything to it !
