DHCP Issues with fiddly router

Kirfew · 09-25-2011, 03:08 PM

Hello, I have an ADSL router that sometimes drops connection. This isn't my main problem, as it only drops for 3 or 4 seconds or so, but when it drops my computer's network gets messed up. After a connection drop, the pc will stop communicating with the router if i try and access the internet, and I have to restart the network daemon.
How can I set up my network/dhcpd to avoid this?
Thanks.

OK Let's see....

What brand of router and was it supplied by the carrier?
Who is the carrier?
Sounds like the router is the DHCP server.

How many computers on your network?
What OS are you using?
Static or DHCP supplied IP addresses?

Did you set up the gateway info in your computer?
What about your DNS settings?

Post back.

The problem persists with different routers, my carrier is Telkom, yes I think my pc uses the router for DHCP.
There are 3 PCs on the network, I am using ArchLinux with a DHCP supplied IP. My rc.conf's network settings are set up for DHCP (interface=eth0, address,gateway,netmask,broadcast and gateway are blank).

You could try setting the computers up with a static ip to test to see if makes an improvement. Make sure to set the DNS and gateway addresses.

In the router, can you set multiple DNS up? Try setting a DNS like google (8.8.8.8).

Have you talked to the carrier about why the circuit is resetting? I know most dynamic circuits reset, but it's worth a shot.

If you tried different routers, you can try setting up internal DHCP server but I would try the other things first.
