Road Runner and Router -- used to work great!

[robpay]

I have Road Runner, which was working fine until yesterday, with a router and one other PC on the internal LAN side.

Everything worked well until yesterday -- when I could not connect to the Internet from either machine.

I called RR and they had me disconnect the router and release the IP's and connect straight to the modem. It works fine.

If I connect the router back inline -- it doesn't work.

The IP under ipconfig is different from the IP that the router obtains when it configures.

I'm running Win2K Pro, Linksys 4 port router BFRs41.

The router is setup to be the DHCP server and set everything automatically -- which has worked fine until now.

Can anyone help? Is the router bad? Or did RR set up static IP's. Any help greatly appreciated!

prolly u need to clone the MAC address of your PC NIC to your router.
RR identifies their customer by their MAC address (i believe)

They ID by the MAC address on the cable modem.

What happens when you release/renew the IP on the router when hooked up?

is it ???
can someone clarify here ???

I have RR. They ID by MAC on modem.

edit: btw, I am in NY, Liberty division of Time Warner Cable.

When I release and renew via Win2K -- It is successful and I get the same IP.

The release and renew from the router, same -- successful and I get the same IP each time -- only it is a different IP from the modem only.

And this all worked great 2 days ago.

Try configuring your router to use the IP that your PC gets when you use the PC direct to the modem.

I was just getting ready to try that -- but now the IP has changed.

I'm unsure what might have happened -- but, the IP that the router gets is yet another IP. And it gets all the info -- DNS stuff and all.

I can see and reach my other PC through the router, share files, etc.

I guess my feeble knowledge of how this all works has now gotten me in over my head!

Hey! Thanks for everyone's help and interest -- this is truly a great resource!

But this is the deal!

ROAD RUNNER CHANGED!!!!

I found on practically networked a deal about the MAC addresses.

ROAD RUNNER must have started using a recognition device with the router MAC and then blocking service.

So others may run into this issue soon if they haven't already.

i thought that they started using mac authentication when that happend to me...This is whatyou try
just turn off all network equip for 90 sec or more nad then it should all work fine then!!

I had the exact same problem here in Austin. Was using an older, single-port D-Link Router. Same thing happened to me last Sunday. My entire network was set up DHCP. Also have a D-Link 4 port. Hooked it up and the problem persisted.

I could get one machine to connect both through the router and straight into the modem. However, through the router, more than one would not connect. A tech support call to RR released 3 IPs which were in the modem.

So, I set all 5 boxes to static IPs. All now work great. I haven't had a chance to check everything out, but tech support told me they had "changed some things".

I believe just be turning off and keeping off the cable modem for a couple of minutes (around 3), is whats need to "reset" their MAC address table

RR here in memphis prgrams the modem to allow the number of IP's you paid for to pass the modem.

If you pay for 1 IP, the pc that hits the modem first is the only IP that gets through the modem to the internet.

If you hook up your pc without the router, and then hook up the router, the modem only passes the IP of pc through and blocks all new IP's.

So, remove power from the cable modem to clear it's memory, and then hook up the router first. From there the router should take over.

I don't see what the issue is here; your set up still looks like

| wall | ===coax=== ||cable modem||------------[router]-------------------PC network

right?

How is your router getting in the way of RR authenticating the MAC address of the cable modem? Configure your router to use DHCP to grab an IP address; use RFC1918 [192.168.0.0/16 is a good range] for your internal network, and you should be fine. LMK if I'm missing something?
