Ok better start on a new post.
Hmm..
Just did a factory reset again.
Disabled and enabled my connection, ok no 1 minute "Identifying" wait.
Logged on to router.
Strange, no captha this time round after this second factory reset.
Set up internet and wireless stuff.
Shrink DHCP from 100-199 to 100-125 this time (26 slots) just in case since it allows 24 reservations.
Reserved IP for my PC.
Log out.
Disabled and enabled my connection, ok no 1 minute "Identifying" wait.
Turn on sis' Mac.
Straight away it gets IP.
Disabled and enabled my connection, ok no 1 minute "Identifying" wait.
Logged on to router.
Both computers appear at DHCP Client List.
(Always when the other computers don't appear there, there will be the problem)
Reserved IP for sis' Mac.
Log out.
Disabled and enabled my connection, ok no 1 minute "Identifying" wait.
All ok for now after the second factory reset.
It was ok too after the first factory reset on Monday.
After I reserved the IP for the computers that day, I found that they are still holding their old IP.
And I turned off the router and modem (share same socket) to make the router forget.
Then when I turn on and logged in I found that the our computers are not listed at the DHCP Client List anymore.
But they did have IP and can access the net.
And there was no 1min wait then when I disable and enable my connection.
Wasn't until the next day when I did a full IP reserve of all 10 slots that the 1 min wait reappear.
Unchecked 2 slots and the wait disappears.
But later that night when I return home, the 1 min wait appears again.
Then it led to the second factory reset as described above.
Sorry for being long winded but I'm trying to give enough information.
Hope someone has an idea of whats going on.
Thanks.
