Whenever this modem drops out and reconnects, I have to either reboot the router (WRP400) or log into the router and renew the IP address to get access to the internet.
I've been testing my mate's DLink 504 G, and whenever this drops out, the router seems to get it all sorted by itself.
Thanks guys, thought it might have been those settings but couldn't remember the values or where I saw them.
If anyone knows the answer my second question let me know. Should DHCP be enabled on both the modem and router?
For the record, the router IP for the interface is 192.168.15.1, which doesn't make a whole lot of sense to me, as it is out of the range of IPs on the modem (192.168.1.2 to 192.168.1.254)
No you will be fine leave it as it is, the wrp400 default LAN IP is 192.168.15.x , thats so it dosn't clash with the other devices LAN addresses as if the AM300 was on that you would have issues you can't route from one device to another on the same IP addresses range
I will ask my mate who's a network support guy. But any ideas why the router will automatically connect to Dlink 504g automatically when it connects to the internet, while the AM300 requires the router to renew it's IP address by clicking the "Renew IP Address" in the routher interface or by restarting the router?
My knowledge of electronics is very good, but of networking is dangerous. I think the router does not know that the modem was restarted and so the router needs to request a new IP address. The D-Link might handle this automatically, or simply allocate the same IP address, or has less security. You probably do not need to use DHCP and can simply use static, which should solve the problem. (Again, take this as an idea rather than absolute truth.) I have the same problem with my setup, but it is running on a UPS so the modem never needs reseting.
Note that even minor power surges through the mains can couple through the modem power adapter and cause it to either drop the connection or reset. And surge "protectors" does virtually nothing to prevent it.
Thanks Maverick, "Always on" is enabled and always has been.
Neil, my issue doesn't arise from the modem losing power. It drops out because the signal on the line is so week. (The good guys at Xnet are running an analysis on it for me now)
So the modem still has power, the network light is still on, yet the router can neither get an internet connection when the modem does reconnect automatically, nor can I access the modem interface page at 192.168.1.1.
I thought about static IP's, but it's a little over my head. I'll try my mate.
Mine does exactly the same if there was noise on the line and the connection dropped. On the Dynalink there is an option to renegotiate the connection with the exchange without dropping the connection with the ISP server, seems to have solved my problem most of the time.
Static IP should fix it as well, but I'm just too lazy to do it since I don't have that much of a problem any more. But when I do get it, I log into my router status page and click on renew IP address. That re-establishes the connection between the router and the modem, then everything works fine again.
Give your router a static IP the same as the modem, except change the last digit from 1 to 2, and disable DHCP on the modem. You can also keep DHCP enabled on the modem, but then change the DHCP range on the modem to start with a number higher than what you allocate to the router.
Note that you need to keep DHCP enabled on the router network side, else your PCs will not get automatic IPs from the router. The part you want to make static is only between the router and the modem.
