DSL connection solved, but a new issue (2wire 2701-hg)!

The Internet Connect window doesn't even show Ethernet! The 2wire is a router, it's negotiating the PPPoE connection with your ISP and and then assigning an IP address via DHCP to your computer(s). It possibly has a nice firewall built in, so security won't be a problem, but you should Google for "2wire 2701-hg" (with the quotes if you want); bring up an emulator and a manual and stuff. These companies tend to keep this kind of thing onlne. The information you used to get is now contained in the 2wire's config screens. Google, as I said. -- W. Oates |

(in article ): The 5360 used to work with something called PPPoE. PPP = Point to Point Protocol PPPoE = PPP over Ethernet PPPoA = PPP over ATM ATM = Asynchronous Transfer Method Dial-up uses PPP. DSL uses either PPPoE or PPPoA. I have never seen a DSL connection in the US which uses PPPoA, but it's common elsewhere. I had an icon in the toolbar that showed if we were connected or not. From the drop down menu I could ask to connect/disconnect. With the 2wire, I had to uncheck PPPoE. If the modem is now controlling the connection, your Mac doesn't have to do it, too. In fact, your Mac _can't_ do it. This is a Feature Not A Bug(tm). Instead I had to select DHCP in "TCP/IP" pane. Whatever all those letters mean. DHCP = Dynamic Host Control Protocol TCP = Transmission Control Protocol IP = Internet Protocol This means that your modem has a router (and, probably, a switch if it has more than one Ethernet port) built in. The router is handling your local network's connection to the Internet. That's its job. Again, this is a Feature Not A Bug(tm). Of course, the PPoE icon is useless. The Internet Connect window doesn't even show Ethernet! So the connection is there and works, but I miss the information I had, and control in connecting/disconnecting, which I did as safety feature if I wasn't planning to use internet for a while. Your modem is handing PPPoE now, so the info is on your modem's HTML page(s). Usually those pages also allow you to control various aspects of the modem's operation. The tech said it is not a good idea to disconnect the modem, just leave it on forever. That's usually a good idea. But that way I feel anxious about security. By disconnecting and then connecting, the IP address changed, which people had told me contributed to security. You can have the modem disconnect after a given period of idleness. However, as you're behind a router now, you can use NAT (Network Address Translation, built into the router) to hide your private network. This gives you security, in that someone on the outside knows what the IP of your WAN (Wide Area Network) port is; that's the IP your ISP hands out, and is the IP for your DSL connection. I suspect that this is 75.3.125.224, which anyone can read off your usenet posts and your emails, and any web connections you make. What they _don't_ know is what the IP of your computer is on your local network, and without that they have a problem getting to your computer. (Well, if you email them, they can find out what your IP was when you sent that mail, if you didn't spoof it. And a typical home network would be a Class C, with only 254 possible IPs, so it wouldn't be too hard to brute-force things if they think that you have a Class C, even if you _did_ spoof your IP. On the other hand, you could set up a Class A private network instead... 16.8 million possible IPs is a trifle many to search unless the bad guys want _you_ specifically.) -- email to oshea dot j dot j at gmail dot com. |

Fair enough but why did this work with 5360 and not with 2701-HG? I suspect that the old unit didn't have a router, or if it did, that it wasn't set up to handle PPPoE. DHCP = Dynamic Host Control Protol, will run on a local/remote server assigning you an IP # without having you fiddle with it. Also sets your DNS (domain name system) server, But wasn't the same happening with the 5360 and PPPoE? Not necessarily. It depends on how the device was configured. Guessing from what you /seem/ to know, you wouldn't want to bother any forther, inasmuch as it seems to work now. You may have a point there, but I'd like to get some idea. -- email to oshea dot j dot j at gmail dot com. |

DSL update

G.T. wrote: I would replace it if you can. I had a 5360 finally fail on me after sporadic issues like the above. What did you replace it by? ATT is using Siemens Speedstream 4100(?) as standard dsl modem. Some post suggested they are going to move to Motorola Netopia 2210 (?) but at least ATT online store has no mention of it. Honesty, it doesn't really matter. All the consumer-grade modems you can buy will eventually fail. They are not meant for true 24/7 always-on use. At least not the models I've seen. Usually, it is some discrete part that dries up or burns out. Heat is the killer in this case, and if you can find a modem with an actual metal backplane that aids in passive cooling, I would snap it up. -- clvrmnky Direct replies will be blacklisted.

Are lien-filters and cables generic or modem-specific?
One last clarification...
As I have mentioned in other posts my old dsl modem Speedstream 5360 died a few days ago and since then I have replaced it with the 2Wire 2701 router/modem. The 5360 came with (1) Power supply (2) Phone line cable (3) Ethernet cable to connect to the computer (4) Line filters for other phones Which of these accessories are specific to that modem (and thus must be discarded with it) and which ones are generic (and thus can be save for possible future use in other situations?) I am assuming that the power supply is modem specific, phone cable and line filters are generic, not sure of the ethernet cable. But I thought I'd ask just to be sure. Thanks. |

All are generic except the power supply. If the power supply has a label specifying voltage and current output you could use it with some other device with similar power requirements.
