Problems with Netgear RP614 v3

post #1 of 5
Thread Starter 
Hi again everyone. Here's the deal. I recently moved. I have Comcast digital cable with cable internet. The cable goes to a Motorola SB5100 cable modem. We used to have the same setup (with a different cable modem) at the previous apartment, and the modem was connected to a Netgear RP614 Router/Switch, and it worked just fine. I didn't set up the router in the first place, so I'm not sure what settings were used. Anyhoo, as you could imagine, during the move, the router lost it's settings and was reset to factory default, so when connecting the modem to the router and plugging the router into the computer and opening a browser window, the "router setup window" loads. Here's what happens:

The router detects that a static IP address is assigned (it's detecting the static IP address given to the cable modem by the ISP--but we get dynamically assigned IP addresses to computers/peripherals from the ISP), and goes through the menu of inputting the default gateway IP, subnet mask, DNS settings, etc. So here's what I do. I run ipconfig /all on the computer when it's connected directly to the modem to get the correct static IP address of the modem (and other settings previously mentioned), and after connecting the modem to the router and the computer to the router, I use those settings I got from ipconfig--but it doesn't work (no type-o's). So then I go back into the Netgear Config utility and select "automatically/dynamically assigned IP address" (which is what it should be), and the config utility still fails--it can't detect a connection to the internet, same as before using a static IP address option.

So I'm at a loss. I'm pretty much an amateur when it comes to setting up and troubleshooting this--all I've done is what I have tried before in setting up a router (and it's worked in the past)--and I don't know why it ain't workin' this time...

PS--the network adapter is set to "Obtain an IP address automatically" under TCP/IP settings for the adapter, so computers are being assigned IP addresses just fine from the ISP--for some reason there's a communication problem between the ISP, cable modem, and router. Any ideas? Sorry for all the text!

The Surfboard modem does not like to be dynamically switched. You need to setup your router for DHCP (this is what comcast uses, i have the same modem), then reset both the modem and router. The modem "synchronizes" with whatever device is connected to it, so anytime you connect something different the modem has to be reset (ie if you change from direct to PC to modem>router>pc, the modem has to be reset).

Before i got my router i had to reset the modem every time i wanted to swap my Ethernet cable from my PC to my XBox and viceaversa.

Thank you SO MUCH--I'll give this a try when I go home (probably not until tomorrow sometime). I'd been wrestling with this for the last two days, wondering why the hell it's not working. I mean, I'm no pro in this area, but definitely not too much of a noob...didn't know about the surfboard not liking to be dynamically switched (but come to think of it, now that you mentioned that, I notice that's the case, even when switching between two computers).

Thanks again. I'll +rep ya now for the response, and I'll rep ya again when it works!

LOL, that isn't necessary. Just glad it's workin for ya . For a general rule of thumb, anytime you're changing settings or connected devices on home network equipment, if it isn't working, reboot it .
