WAN Issue - lost IP from ISP every hour #38

Closed skdubg closed 10 years ago

skdubg commented 10 years ago

the WAN interface is loosing the IP from ISP every hour, then the interface become an IP from routers own dhcp (192.168.200.xxx)

a restart correct this, but the problem comes back.

is there a solution for this?

Chadster766 commented 10 years ago

The Status => Network section will show the LAN instead of the WAN until you blank the LAN gateway address in Network => Interfaces => LAN and Apply\Save.

Try the above and see if it help with displaying the right WAN status in LuCI.

hi Chadster766,

the problem is not the wan status displaying at overview page. the router disconnects at wan interface and receive an IP from his own dhcp.

(the IPv4 at wan is changing from ISP to 192.168.1.225)

Chadster766 commented 10 years ago

I assume you are running V1.0.1. Your WAN6 is configured 6in4. Could that tunnel be the issue?

The only way I can see the WAN getting an 192.168.x.x address is from a DHCP server on the WAN side.

skdubg commented 10 years ago

WAN6 is stopped. first i was on v1.0.4 with this issue, at the moment its running v1.0.1 without this for the last 2 hours maybe.

now i went looking for the next hours/days. it could be a problem of v1.0.4 i think

Chadster766 commented 10 years ago

Please reply back with results. If this is the case I might remove V1.0.4 due to too many issues.

skdubg commented 10 years ago

hi Chadster766,

the issue is at v1.0.1 too.

Chadster766 commented 10 years ago

Thanks for the reply.

This means that there is a DHCP Server running on your WAN Port. Probably your ISP modem\router isn't in bridging mode or malfunctioning. I could also be some sort of tunnel that you could have configured on the WAN6. How did you disable WAN6? It still seems to be operational. You can safely delete WAN6 but NO other network connections.

No one else is reporting this issue at this time.

skdubg commented 10 years ago

i have delete WAN6 in interfaces. i try it again. ISP modem is in bridge mode, a netgear and dlink router with OpenWrt are working well.

i'm reply back in a short time

I found the problem at my network. There was another Router with a collision.

Thanks Chadster766
