I tried everything you suggest me but nothing.Am kind dissapoind for a new user using antminer s1
Can you post an screen shot of Network overview status ( when you log into your S1 status page is loaded, scroll down to the network ).
Do you have any security in setted on your router?
Does the time sync with time serves ? You can see this on system log page, S1 tries to sync time right after reboot, and you will see this in system log if it has errors on or it works.
I assume you have problems with DNS.
Maybe you should try to input an pool address with IP. For stratum.bitcoin.cz is ip 95.211.52.40 .
