Re: OT: ATTBI cable modem replacements
My Terayan TJ615 has a built in web server to gain entrance into the config settings, which is using the private class C address of 192.168.0.1. It has no DHCP server running, but it is capable of obtaining an IP address for my firewall box. I think that is standard for cable modems, but I have been known to be wrong ;-) I missed the rest of the discussion. James Dorr [EMAIL PROTECTED] - Original Message - From: Matthew J.

Re: OT: ATTBI cable modem replacements
I have an older Motorola SB4100 with a Linksys BEFW11S4 and no problems. A while ago while downloading new firmware I came across the BEFW11S4-AT BEFW11S4-AT - EtherFast Wireless Access Point Router w/ 4-Port Switch Notes (ATT Broadband Approved Version). In any case, one of the things I set on my router is the MAC address to match the MAC address on my desktop system. I also keep a copy of Windoz so that whenever I have to talk to the customer service people, I can boot into Windows and detach my network.

Re: OT: ATTBI cable modem replacements
I've talked to several people about this. It seems very problematic. I've one friend who refuses to upgrade due to hearing about all of the problems. I've another who is unable to get his BEFSR41 working although a single PC is working fine. It was suggested, to him, that he interpose a cheap hub between the new cable modem and the BEFSR41 and it would work. Sounds a bit strange to me. One friend who has succeeded in getting this working indicated a couple of things. He said the new cable modems are capable of giving out addresses (they have a DHCP server running). He connected his Linksys and PC up to the new cable modem, which has an IP address of 192.168.100.1, with NO connection to the cable system. So, just the cable modem the Linksys and a PC connected together via Ethernet, no other connections. Use the PC to log into the Linksys and verify that you get an address (probably 192.168.100.11) and that you can ping 192.168.100.1. Apparently some of the cable modems will not step down to the 10BaseT required by the Linksys. If the standalone connection works you should then be able to connect the new cable modem to the cable connection with just a PC and go to the special web site to register the new address. Finally, add the Linksys back in and you should be golden. Apparently there is a VERY HIGH failure rate on these new cable modems. I talked to one person who said he went through three of them before getting a good one. I don't know if this was that 10BaseT step down problem or something else. I'd love to hear anyone elses experiences since I've several friends I need to upgrade.
