Cable modem and Router problem

Okay, just switch from a STATIC IP DSL connection(too expensive) to a "Dynamic" IP Cable connection.

And just retire my good old Barracade 10bps router and get a Linksys 4-port 10/100.

And, these 2 things(Cable modem and Linksys 4-port) don't see an eye-to-an-eye...🙁

Plug the network cable from the cable modem to any PC, it would work. No sub-net mask, no DNS, and with dynamic IPs.

Plug it into the new router and try to distribute the network cables from it, and nada.

Any idea? At least when I have the STATIC with Barracade it was easier & straight-forward(punch in all the number) to configure...
 
You probably need to clone the MAC address from your PC onto your router.

Most cable companies use DHCP to assign IP addresses, etc., and tie that to your Ethernet card MAC address. By cloning the address on your router, your ISP thinks your router is your PC and hands over the required info.

Go to your Linksys configuration screen, click Advanced, then click MAC Addr. Clone and plug in your PC's MAC address.
 
command prompt window.
netstat -rn
it will be the string of 6 pairs of letters and numbers, on the second line.
 
Depends on the OS. ipconfig in Start / Run for Win98.

BTW. What do you get from your new Router that the old one could not do?
 
Okay, did find the MAC address and clone it to my router...but still not working...🙁

I know this is a dynamic connection...any other step I can take?

Cause sometimes even when I plug the cable, directly from the modem, into my PC, and I still won't get a connection. After hooking up to the router, I decided that connection is more important so I hook the cable directly from the modem...but it takes me several "restarts" on my system for Internet access; the first reboot won't allow me to get online.

SO strange...I'm beginning to think about going back to DSL now...seem to me that the STATIC IP one is much easier to configure...?
 
is there any URL/web_site that I can find some kind of step-by-step setup for this? Please help me out here...🙂
 
Cloning the MAC address is only necessary if your cable network is not working on a DOCSIS platform. If you have a DOCSIS modem, then you won't need to worry about MAC addresses.

Why is that? I have a DOCSIS modem and I have to clone my PC's MAC address on my router in order for it to work.

It depends on how your cable provider has everything set up. But I don't know why we're talking about cable modems and DOCSIS stuff here, he said that he has DSL 😛 Dean_Jen, what DSL provider do you have? At work, I occasionally ran into a few problems with Verizon DSL and Linksys routers- it would take FOREVER for the router to obtain an IP address from the server. Sometimes 15 minutes, sometimes even 45 minutes. Same thing would happen if I tried plugging it in directly to a computer and manually release/renew an IP. Just let it sit for a while and see if that works for you. Hope this helps.
 
yup.

USED to have a STATIC IP DSL...which is easy to configure since I have all the necessary information.

But now with a Dynamic IP Cable...while the connection does seem to be faster, I still can't configure my router...🙁

Any suggestion?

I just went through this with a D-Link 704P, once all connections were made I had to open browser and type in a specific URL addy and use their set up wizard. Every thing went smoothly.

I don't know about Linksys but check herehalf way down page is BEFSR Tech Helper might be what your looking for.
 
emailed Linksys, so let's see how they reply.

Will try my friend's D-link 604 and see how things work out...mm...

meanwhile, anybody has "Dynamic" IP Cable modem and can share his/her experience with me? Thanks a million...🙂

I have Adelphia Powerlink w/ a dynamic IP address, using a Linksys BEFSR41 and have no problems 🙂
 
connect the cable modem and the router with a hub, that's how I resolved the problem, quite funny, but that's the only way out for me. 🙂
 
Mine is a DLINK DI 604, it refused to communicate with a dlink cable modem, DCM 200. But it works fine with DSL. Sent back to DLINK and got a refurb one, the same problem happened. Also tried other routers, didn't work either.

Seems like the connection b/t the router and the modem has some problem, I tried both cat 5, cat 6, as well as the cable to connect two comps. Have absolutely no clue of what's going on.

When the router is connected to the modem, the act light on the cable modem should flash, if not, means the modem is not getting signals from the router. But if you connect the computer direclty to the modem, and see the act light, it means the modem is working fine.

🙂 Good luck!
 
Dean_Jen...

What's up bro? Haven't seen you since we met at Fry's for that GeForce card...way back in the day...

What brand modem is it? and is it a BEFSR41 Linksys router?
 
Hiya all..

Okay, it's working now...all I have to do is to turn the modem off before I connect everything through, and viola!😛

Yup. that's the LInksys model. Right now it's working like a charm...🙂
 
I've seen that before. If you have a power failure, you'll have to do that again, it seems one boots faster than the other, and they sort of miss each other in the process.
