My phone (HTC One X) can't get internet when connected to my office wifi network.
My office's wifi has no problem for me and my workers.
By default, my phone uses DHCP mode when connected to local network. However, it adamantly picks the same IP that conflicts with another server in the network. In DHCP mode, I get no internet.
I switch my phone to static IP (along with the correct gateway and DNS). Even with a good internal IP address (no conflict, I checked in the router), I still get no access to internet. I used Fing on Android to ping machines within the network successfully, but pinging any domain name at all would fail.
I even tried switch DNS on my phone to 18.104.22.168 and it won't work. Pinging any external IP would fail
I have no problem connecting to my home wifi (DHCP mode) that has the same router model.
I'm out of ideas. Anyone?
