Cable modem and router problems

[thomas]

Since 15 days I suffering a problem that my router & my modem not works properly. The modem works fine when it connected with computer via Ethernet device and the wireless router also doing well as expected by its own. When I am trying to connect this two, it don’t want to communicate.

Same problem I also facing, When I turn on the router, it exchanges some sort of data with modem for few seconds. Then the light abruptly goes dead. From the configuration, I see that it does not DHCP server.
What I do next?

[Sam]

Please check with the IP assigned by your computer & also check the ISP’s IP. Then try to connect with network with help of router & modem.

I see that all IP’s are dynamic, & the ISP’s IP also same as that they ask. There is some sort of problem with your modem while communicating with modem & router & modem takes plenty of time while communicating each other.

Ok, I understand that there are problem with my modem & router. Is there anything else that might not works properly?

[joe]

Have you tried that turning off your modem & router? Also you can turn off your computer & they trying to connection between the router & modem.

[joe]

Please try to power off the modem and router for at least 30 sec. Now power up the modem & give time up to 45 sec for warming up. After that plug in the router to modem. Now see that the problem still arrives or not.

[frank]

Unplug the cable modem. Ensure that the cable from the modem is plugged into your router. Turn on your router & plug in your modem back. Now your router resets and detects a new MAC address. It have to fix your problem.

[Sam]

Your modem should work after resetting your modem.

[Mel]

I do the all the steps followed by you but it’s not working.

[frank]

Let, first check that the MAC address assignments to DHCP server. Please take ISP providers help to get such MAC address assignments to DHCP server.

[Sam]

Call your ISP for assigning the IP address while communicating with your NIC Card. It might uses Static IP. You can reset your router to solve it.

[joe]

I worked it sometime but it is good to verify that I’m connected or not. I did it on my SURFboard modem. One thing I told that it takes more time to do it.
Thanks,

[joe]

My computer assigned IP address dynamically. Could they fetch the MAC ID from NIC through my cable modem? Let me check it & that it the problem or not.

Finally, I got the solution. The router configuration has a little bit confusion that dropped your speed up to 100 mbps to 10 mbps. Everything going smoothly with a capital SMOO. I had no idea to set this one or the other. The router manual doesn’t mention it. I found that by randomly seeing the configuration pages.
