Technical Question about ADSL
« on: October 21, 2004, 08:10:53 am »
To cut a long story short, this is the problem:
Due to whatever reason the damping on my phone cable from the connection centre to my house is 63dB, not 20.5dB as was originally measured.

The bandwidth I (should) have is :tdown: 1.5MBit/s and :tup: 256kBit/s. I never actually reach these values, but I don\'t mind that. What I do mind is, that when a lot of people in my area seem to be on the internet I get irregular disconnects. The modem loses sync for a short time, either lagging me hard or causing the router to disconnect. I of course only have problems with incoming packets (downstream uses the higher frequencies which are cut off first when the signal degrades).

Now to the question:
If I \"downgrade\" to a slower connection, like :tdown: 334kBit/s and :tup: 64kBit/s, could that possibly eliminate my problem?
When does an ADSL modem resync? It\'s hard to put into words, but as far as I understand there has to be some measurement on available bandwidth/signal strength that the modem uses to decide what there is to do.
So is it like \"huh, trouble above 1MHz again? Let\'s do a resync, yay!\", and would perhaps not do that if it didn\'t even expect a signal >xMHz (smaller bandwidth)?

I\'ve had it with all that sh*t. I\'ve spoken to the so called \"hot-line\" which is not so hot after all than rather stupid like a loaf of bread. They do not know their own prices.  They tell me that the IP that I have on my router\'s \"outgoing\" port \"could not be\". The phone line must be made of rubber as its length changes from 1.8 to 2.8km randomly (according to them). Service-line-girl A redirects me to service-line-guy B who redirects me to service-line-girl A who...

I am about one centimeter (metric system :P) away from either suing them or tearing my own arm out and beat them up with it, but unfortunately stupidity is not a crime in this country.
If anyone has a good suggestion please help! (or would you prefer HLPPPPLLLZZZzz!!!!111eleven? :P)

Don\'t tell me to
- check the LAN card
- check the router
- check the cables
- check the modem
- check the wiring
- check the configuration
- check the splitter
- try another computer
- try another LAN card
- try without the router
- try another modem
- try another splitter
- check if my monitor is switched on
or I will have to hurt you ;), because: \"Been there, done that\" like a million times.

The internet is "the terrorists'" most important weapon, they say.
Wrong.
Fear is their most important weapon.
Ours is our freedom.
