Today everyone can make a dsl router/modem, and ISPs when they |
| 33 |
give you equipment they want it to be cheap. I saw exactly the same |
| 34 |
problem on cheap dsl routers, I don't have enough knowledge to debug |
| 35 |
it, or to be sure if it is safe or not, it worked for months with no |
| 36 |
issues, no reboots ..., one day it stopped working/resolving hosts, and |
| 37 |
its dhcp server config doesn't allow "forwarding" of DNS servers from |
| 38 |
WAN configuration, or manually setting one which will be given to the |
| 39 |
dhcp "clients", so there are two ways, it can work as a proxy (send |
| 40 |
its own IP as DNS server to clients), or it doesn't provide DNS, so you |
| 41 |
need manually to configure each client. |
| 42 |
If you restart the router, it works sometimes for few hours, sometimes |
| 43 |
few days, but it will fail again randomly. |
| 44 |
The only worrying thing is that it worked for months without an issue. |
