Comcast Speed issues.

[asiandiscovery]

First off, i like to say, i've done the cablenut tweaks, virus check, spyware check, and all of that. Doesnt do anything, and this is really annoying. I am running the Scientific Atlantic modem that came with the service. I should be getting btwn 4-6Mbps. When i first got it, it ran around 5Mbps. If you know whats wrong plz tell me.

try this...

change your DefaultReceiveWindow to 768000

change your GlobalMaxTCPWindowSize, TCPWindowSize, and MaxFastTransmit to 90520

[asiandiscovery]

I did that, it didnt do anything.

I highly doubt that cablenut is gonna solve my problem.

[ufjoe21]

try a power cycle.....call your ISP and make sure it's not a problem on their end too

[asiandiscovery]

Well i called them up, and the guy who talked to me said, they might be doing some maitenence around where i live, and that my speed would only be down for probably tonight. Although i do suspect thats just what he told me to get me off the phone, i guess ill wait till tomorrow morning to see whats up.

Thanx for the help anyways though. Hopefully this will all be solved by tomorrow.

I'm still having slight problems with the internet, even though it did get better the next day.

I took off the cablenut tweaks and it works a little better. But if you have any custom recommendations i can try them again.

Comcast has been like this for me for 2 weeks. I live in SW MI, I guess they are doing network maintence somewhere and its affecting us. We are both about the same speed, i used to consistantly get 6meg but now im at 1-3meg
