Bad DSL connection

I recently decided to spring for a DSL connection, as dialup was simply becoming too slow. I got the DSL installed, and decided to play some Counter Strike: Source. To my dismay, there was unbearable lag, making it impossible to play (even worse than dialup). I have a 512/512 DSL connection from a local provider. Many of my neighbors have the same connection and do not experience the same problems I'm having. Does anybody know of a solution to this problem?
 
Noise on the phone lines may degrade your DSL performance. You can try to ping the CS servers and see what your latency is. It could also have been just a bad time. Have you tried it at different times with the same result?
 
You might want to call your provider and have them run a test on your line.

How is your browsing? Do web pages come up at decent speeds?

Have you done a speedtest? What are the results?

Trying pinging your DNS server and see how many milliseconds the response takes

Give us all that info... without it... we dont really have much to go on

Reset the MTU on your PC. It is set for dial up and not good for high speed.

My browsing is alright. It's much faster than the dialup I replaced it with.

The speedtest typically nets me in the area of 300/280.

How do you ping your DNS server? Also, how do you reset your MTU on your PC?
 
Guide to use this TCP Optimizer.

Go to a command prompt and do an "ipconfig /all"... that should show you the DNS servers your computer is using (unless youre hooked up to a router sometimes)

if one of the DNS servers is 65.123.123.123 then you would type in "ping 65.123.123.123" and press enter

post how many milliseconds it takes to get a reply
 
I tried using the TCP Optimizer, but there was no change as far as I could see. The command prompt didn't work either. Any other advice?
 
Can you hook up your computer to a neighbors DSL? If you could... it would help as a process of elimination...

If its still slow, it could be your computer...

If its fast... it could be your houses internal wiring, the DSL modem, or some other line problem
 
Tangerines, try to get the noise margin (SNR) information for your connection. This can be read either out of your modem or out of the DSLAM you connect to. I don't know what modem you have and I don't know whose DSLAMs your ISP is using (they don't look big enough to have their own, they probably get the L1 connectivity from your LEC), so this may be hard for you.

Also, try connecting your ADSL modem to the bypass port in your NID and see if that helps. If so, get an ADSL splitter and install that after the NID. Your ISP may be able to help with that. Your inside wiring may be the problem.
 
I had problems with my new (well new at the time) DSL right after i bought my house. I live in a neighborhood where all the houses were built in the mid to late 70's. I called the phone company to complain (Qwest), and they sent a tech out to check the lines. Turns out that the signal was really lousy, apparently due to the phone wiring being run to about 5 houses in sequence. He said something like the signal would reflect back from each connection, causing noise for everyone. This is all what i remember, it was 5 years ago. In the end, the tech said that he essentially just cut the other houses out of the loop, as most of the wiring wasn't being used anyway. My signal quality went up by like 15db, and it's been rock solid ever since.

I guess the short version of that is: call whoever owns the physical lines and have them check em out. Getting the signal strength from your dsl modem will help when you talk to them, they'll probably ask you for it.
