Losing Internet Connection / Speedstream 5360 DSL modem connects to a Linksys Wireless G (WRT54GS v2)

I have found better success at sites where on the router I have cloned the MAC Address of the PC that was used to register the modem. Some providers will not inform you that they do periodically perform scans on their network and they do deny access to any "unfamiliar" devices. Therefore, my advice is to clone it... it really cannot hurt.

Second - It would also be helpful if you could describe the environment after you lose Internet connection.
i.e...
- What is the activity of the LEDs on your modem? (off/on, blinking/steady, green/amber)
- What is the activity of the LEDs on your router?
- From the web interface of your router, does the status page show valid connection info? (Internet IP Address, Mask, Gateway, DNS)
- Are you able to ping to the LAN IP of the router?
- Are other connected PCs able to access the Internet?
- Do you recieve any errors?
- Have you tried replacing your Ethernet Cables?
- Have you tried connecting to a different port on your router?

Sorry for the laundry list... but the answers to each of these questions should help you narrow down to the problem area quicker. Hope this helps!

I am still having connection issues. This the status when I cannot connect

What is the activity of the LEDs on your modem? The modem lights are on, green, and steady
- What is the activity of the LEDs on your router? On and steady
- From the web interface of your router, does the status page show valid connection info? (Internet IP Address, Mask, Gateway, DNS) shows disconnected
- Are you able to ping to the LAN IP of the router? yes
- Are other connected PCs able to access the Internet? no
- Do you recieve any errors? no
- Have you tried replacing your Ethernet Cables? yes
- Have you tried connecting to a different port on your router? I replaced the router twice

The funny thing is after rebooting the modem and the router everything works great for only a couple of hours. When everything is working good I get an internet ip, mask and gateway and all of the pc's can connect. I wonder if the modem may be bad or if there is bad wiring in the house. Again this is a SPEEDSTREAM 5360 modem, so there is no GUI for it. Today when it was not working again I connected the ethernet cable from the modem directly to my laptop, and I actually had to reboot the DSL modem at least 3 times before I was able to connect to the internet and I got an actual solid DSL light on the modem. This issue is really driving me up the wall. I have the router set as router not as gateway in the Linksys Advance Routing setup screen, and the dhcp portion is set to 0 so it renews once a day. I called SBC they are sending a tech out to check the wirring to make sure everything is ok. I dont know what else to do.

Although you may have a faulty modem or problems with your wiring, check your PPPoE settings on your router. Verify that you have the "Keep Alive" option selected and that the "Redial Period" is set to a value of 30 seconds or less. This option is responsible for periodically checking the status of your Internet connection and attempts to re-establish a connection if it is lost. If this value is already set to 30 seconds try dropping the value in increments of either 5 or 10 seconds.

Also, verify that you have DSL phone filters installed on all the phone jacks in the home with exception of the jack that the modem is connected to and replace the cable that connects your modem to the wall jack.

Hope this helps!
