Problem is: entering android.com or youtube.com in browser address bar brings up page 'This webpage is not available' (Chromium) or 'Unable to connect to server' (Opera) when my router is online.
Symptoms:
- Said two pages cannot be found;
- ping finds something: ping www.youtube.com / www.android com results with 'unknown host'. Without 'www' there are responses from host-213.189.45.121.ggc.com (213.189.45.121) [youtube] and 46.28.247.108 [android]. Both these IPs entered in browser take me to Google homepage. What?
- said pages work normally when I disconnect router and connect my home PC to network cable from my modem without the router in between.
- everything works normally on my laptop, either connected by cable (with modified MAC) or connected via wifi.
My home setup is as follows:
- net cable from my ISP goes to dlink DIR 501 router; my ISP supports DHCP and checks MAC addresses of connected devices (there is MAC associated with my contract), won't connect to net if MAC is wrong.
- in router configuration I entered MAC of my home PC, set admin password and set up ssid/password for wifi. This is the only configuration I performed, everything else is on standard settings (including DHCP enabled by default).
- my home computer runs Debian GNU/Linux, pretty much up to date, and is connected to router with cable.
- my laptop runs Windows 7 and connects to router via wifi.
Aaaand the question is: what is wrong with my configuration, why these particular two pages cause me problems and what can I do to diagnose the problem and fix it?
