Asus RT-AC66R re-connection problem

[mbworldz]

I have the Asus RT-AC66R for almost 6 months now it works great. But the problem I have is the re-connection. I am using the charter cable internet, last night I disconnect the cable modem to test something, but once I re-connect my AC66R to the power, trying to get internet connection. It will not work. I think it took me like an hour to get the signal back. All the lights from my model looks normal. For some reason the router not receiving signal at all.

From the admin page, I don't see any green computer icon on the upper right which lights up when it is connected. The internet status only showing disconnected.

I also noticed the lease time and lease expires only shows "renewing" something like that. But it look like an hour i gain my connection back.

Is this a known issue for this router? From my old Linksys and netgear, never happened like that, I mostly get signal immediately.

I am using the firmware 3.0.0.4.374_979

I unplugged the router, cable modem like tons of time, re-connect, disconnect wait for minutes , reconnect, Nothing happen. So basically it will work but it takes super long time.

Hope someone can help me out here.

Thanks

Since Charter is your ISP, make sure you go to your router's WAN page, and set DHCP to "Normal" (if it was set to "Aggressive"), and also that you are running the latest (374_4561). Charter is overly aggressive at blacklisting routers if they receive to many DHCP queries in a short period of time, which is what this DHCP setting will take care of.

Thanks for the reply. It was set to aggressive mode by default I think. Now I changed it to normal mode.

My question is if I try unplug/turn off the router (just to test the router). and cable model. Wait a minute and turn it back on, would I still have to wait an hour to get the connection back ? will that setting to "normal" fix the problem?

Also under the advanced setting "LAN". I see that lease time showing 86400. Do I need to change that to a different number or just leave it as it is.

Thanks for helping.

The current timeout value used by Charter is 150 seconds without receiving any DHCP packet from you (it used to be 120 secs, both Asus and I increased that to 160 secs in our respective recent firmwares). So if you unplug the router for 5 mins, that should be more than enough for you to be lifted from their blacklist.

Also under the advanced setting "LAN". I see that lease time showing 86400. Do I need to change that to a different number or just leave it as it is.

Those are for your LAN leases, they are unrelated to your WAN lease.

Oh ic. Btw I am not using the latest firmware, do you suggest to update it?

Not knowing which version you are using, it's hard for me to judge. But considering the various security fixes Asus did in the last two releases it's probably a good idea.

Thanks a lot buddy, "YOU ARE THE BEST".
I updated the latest firmware and did what you said "set to normal mode".
Now I can get the connection back very right after I re-connect the power/cable.
