| 641359 | 2008-02-18 04:34:00 | So Telecom has upgraded a lot of exchanges to ADSL2. I understand this increases traffic speeds. Does ADSL2 reach further than ADSL along the old copper cables? Some rural users are too far from the exchange to get broadband. Will ADSL2 help? |

| 641360 | 2008-02-18 05:20:00 | I heard that if you're more than 2Ks from the exchange, you'll hardly feel any difference between ADSL and ADSL2+. | qazwsxokmijn (102) | ||

| 641362 | 2008-02-18 09:00:00 | my router shows that I'm getting around 3500 Kbps downstream when lucky and downstream Line Attenuation is 47.1 dB right now is it possible to use these stats to determine my distance from exchange so I can also refer to the graph too? the internet plan I am on is suppose to give me unlimited download speed and 128 upload |

| 641364 | 2008-02-19 04:21:00 | There is a formula that crops up here and there on the web that says line length(km) =attenuation divided by 13.8. Also a chart here- www.internode.on.net/adsl2/graph/index.htm that may be worth a look for a ballpark figure. |

| 641366 | 2008-02-19 22:57:00 | My router tells me I'm on ADSL2 now, I think i've been upgraded - but haven't noticed any difference in speed. (except that connection speed is now the same as 'attainable line rate' - but download speed is exactly the same) Mind you, I wasn't getting maximum for ADSL anyway, so it's not surprising. |

| 641367 | 2008-02-21 06:03:00 | I've used those formula before but didn't come to a solid conclusion I'm guessing since I'm only getting 3.5Mb/s speeds, I'm not going to benefit too much from ADSL2, since my line's not that great and by unlimited, I'm just saying that my ISP shouldn't be a limiting factor |
