| 1267357 | 2012-03-29 04:26:00 | I'm helping a friend who has ADSL connection problems. One thing I'm suspicious of is the way he has the ADSL filter installed. This is an individual filter, not a central one. The filter consists of a tail with a standard telecom plug on it. There are two sockets, one marked ADSL and one marked phone. He has a two-way splitter plugged into the wall, with the tail of the filter plugged into one socket , and the ADSL line plugged into the other, i.e. bypassing the filter. The phone line is plugged into the filter. I think the ADSL line should be plugged into the filter as well. Is that right? I need to ask because I have the central filter so don't have anything to compare with. Stuff I've seen on the net seems to say it ought to be connected the way I think, but it would be good to get some more opinions. What symptoms would you expect from the setup he currently has? TIA |

| 1267359 | 2012-03-29 04:59:00 | Dump the Two Way Splitter -- In real simple terms ,The ADSL filter is basically a filter for the phone line so you dont get static from the higher frequency signal. With the filter, the normal phone line goes in one and the ADSL connection goes to the modem/router. Seen many problems with two or three way splitters, the less joins you have between the outlet and line the better. |

I think he has it that way because the line from the router has a telecom plug on it and the filter is looking for an RJ11. I guess I'll have to find a gender changer thingy for him. I'll remove the splitter and see how things develop. Thanks. |

| 1267361 | 2012-03-29 05:36:00 | Wouldn't bother with a gender changer, buy a proper lead, they are dirt cheap, prob cheaper than a changer. | wainuitech (129) | ||
| 1267362 | 2012-03-29 06:24:00 | The lead will need to be about 10m long (don't ask!) which is why I was thinking about the changer. | Tony (4941) | ||
| 1267363 | 2012-03-29 10:55:00 | If there's any way to shorten it you should, those leads tend to be crappy compared to the rest of the wiring. Also if you have any old phones around you can steal the cord from one, they are the same. Plug in filters are not great though, the central splitter type perform much better. |

| 1267364 | 2012-03-29 11:29:00 | It's the 10 metre telephone cable that is causing the connection failures and drop outs. I've seen it happen lots of times. It would be better to use the provided 1metre cable for the modem to telephone wall socket/filter, and then a 10 metre ethernet cable from modem to PC. The signal drop on a 10 metre telephone extension cable is very high compared to that from the modem output circuit via an ethernet cable. |

| 1267365 | 2012-03-29 18:13:00 | It's quite possibly the cord yes but you shouldn't make statements like "it's the 10 metre telephone cable" you can't know that for certain and there could be other issues. I agree with the rest though. | dugimodo (138) | ||
| 1267366 | 2012-03-29 19:38:00 | Yeah, you really want to ditch the splitter and shorten up that phone cable to something around 2m, then run longer ethernet cables, or one longer ethernet cable to a switch closer to the PC(s) | wratterus (105) | ||
