| 207298 | 2004-01-14 01:57:00 | Hi, I got a new Dynalink ALH-181 internal ADSL modem and an Ihug JetStream connection, and am experiencing problems getting any sort of connection. The modem has a little monitor with three states, 'no signal', 'training', and 'data'. Once it says data, it's connected to the telephone exchange, and you click the ihug dial/password window and start surfing. Problem is, the modem keeps falling over. It takes ages to get to the data state, and does it very erratically, or not at all. Once it gets there, I can't surf/download for more than a couple of minutes before the modem returns to the no signal state, dropping me off Ihug. I've tried downloading new drivers, reinstalled the thing multiple times, used several different cables and phone jacks, pulled out my 56k modem and LAN card, and reinstalled windows (XP pro). Nothing made any difference. Ihug couldn't offer any solution, except to say that the distance I am from the phone exchange, this modem should work fine. They suggested a visit from a Telecom techy. He couldn't find any problems with the phone line, and his own test modem worked, returning speeds of 4400 which he told me was acceptable. Problem with the modem, he said, and charged me $70 for the privilege. I took the modem into Dynalink, who tested it and found no problems. The Dynalink dude also said that he was getting speeds of over 7000, and that 4400 was in fact quite slow. His diagnosis was a problem with the phone line. So I have Dynalink telling me it's a Telecom problem, and Telecom telling me it's a Dynalink problem. I ended up taking the computer to a friend's place who has working DSL. It did the exact same thing. Connected for about 30 seconds, then disconnected and just sat there sulking. So I'm guessing the modem is having some sort of issue with my machine/set up. Beyond that I'm out of ideas, and am about ready to return the modem and give up. Any help would be very much appreciated. |

| 207299 | 2004-01-14 02:36:00 | Internal ADSL modems (and external USB modems) are less tolerant of "marginal" signal levels. Poor connection reliability is a symptom. Extrnal ethernet connected routers seem to perform better in this regard. If this is the case in your installation, then there will be nothing wrong with the modem as Dynalink say. Its just not suited to your location. |

| 207300 | 2004-01-18 04:13:00 | If the signal is marginal is it worthwhile pursuing Telecom for futher help, or should I cut my losses and try a router? | someone99 (5112) | ||
| 207301 | 2004-01-18 11:14:00 | If the signal level is marginal for that modem, I wonder how going to Telecom would help? Given the security issues with internal ADSL modems when compared with external routers, I would just go for the router. Perhaps sell the internal, or return it if you can? Avoid at all costs any USB only external router, they are similar to an internal. Ethernet connected is the way to go. |

| 207303 | 2004-01-25 23:49:00 | I've now tried another internal modem, and an external ethernet connected router (a Dick Smith XH1149). Both have exactly the same problem as the Dynalink - a complete inability to maintain any connection with the exchange. When it did briefly connect the router was reporting some pitiful speeds, between 1900 and 3900. Given these failures, is it reasonable to assume the problem is with the phone line, or something at telecom's end? |

| 207304 | 2004-01-26 00:55:00 | Can you describe how your phone line is filtered for ADSL signal? Did you do a self install with in-line filters or did you get a "full install" from Telecom with a dedicated ADSL socket provided from a splitter? |

| 207305 | 2004-01-26 02:52:00 | I did a self install using filters supplied with the modems. The Telecom techy suggested, on the basis of his diagnosis that the Dynalink modem was the problem, that a full install probably wouldn't make a difference. | someone99 (5112) | ||
| 207306 | 2004-01-26 03:35:00 | Are you sure that every phone device in the house now has a filter in line (apart from the ADSL modem of course, being unfiltered) The reason I ask is that things like Sky decoders, monitored burglar alarms and extension / outside bells often get overlooked and soak up most of the available signal. |

| 207307 | 2004-01-27 01:35:00 | Whoops.. After unplugging, then filtering a phone in another room the router seems to stand up fine. Yay. (I did try this with the internal modems, in case you think I'm a complete fool..) Thanks for your help! |
