I have router DI-604 Ver.D1,
to the router are connected 2 PCs and router is connected with DSL modem
I HAD this problem,
on PC everyhing worked ok, on the other one sometimes yes and sometimes
i could't access to Internet i had to turn off and on the router and then it was ok for few hours/days.
On the router is no firewall, no filter as well on the PC's
Originally there was firmware Ver.3.06 so i updated on Ver.3.11
Afterwards PC which worked before, was still working, but PC with problems before couldn't access Internet at all.
So I went back to Ver.3.06, but during firmware uploading i got message, that router is not accesible.
Now one PC work still ok, but from other one i can ping other PC, but can not ping router
(and also can not access web interface for configuration).
I have a feeling like original IP address for router 192.168.0.1 was change.
Anybody can help?
