Hi there

This is my first post on the forum. have been skulking around for a few months looking at things finally decided to join and post.

Anyway, I am on orcon's LLU network with silver+ ti think it is, i live in whangaparaoa and have been told the cables from the exchange to my house are roughly 3.5k's from Orcon.

When i am connected i previously sync'd at 3400kbps and my attenuation was around 53db.

Yesterday my friend and i installed a central filter, only problem was that the dmark point at my house appears to be under a concrete path and we could not find an ETP, so we installed the filter at the master jack.

Now when i connect i sync at 4500kbps but i have 54.5db?

But even though im syncing higher when i do speed tests from speedtest.net i am getting around 1500kbps down and around 500kbps up, most of the tests resulting in about 1000kbps down and 400kbps up.

Could this be due to the higher attenutionn or jst speed issues on the orcon network.

Also speed tests were done to auckland.

Thanks to all.

Basically...

Sync speed is affected by more things than attenuation.  For example: You would have most certainly reduced noise on the line by putting in a central filter and attentuation is just a meausure of power loss of the signal, the filter probably causes a little more power loss for a much cleaner line noise wise.

Speed test results are affected by more things than sync speed.  For example:  Congestion in your exchange, the speed and contention on the backhaul from the exchange to your ISP, the speed, contention and congestion at your ISP's handover and the quality/capacity of their bandwidth and route to the test server.

Thanks for that, this makes much more sense now.

So basically if im not getting very high speeds on speed test like significantly lower than my sync speed is more likely to be an isp side issue rather than something like packet loss from large amounts of noise or corrupted packets?

Cheers

and the Windows TCP receive window value restricting the speed.
