Compuworm, I followed those instructions and got the speed below, and I'm very happy with it. Many thanks again! By jove, I think we've got it! Voltageman, I think there's no more need for troubleshooting, but thanks for your message. :::..

I switched the NIC Card back from 10 to Automatic. I just did as you suggested and changed the Optimizer function from 4000 to 6000. Also, here are the test results you requested.

Compuworm: I can't believe it! I'm getting speeds of more than 6 M now! (See below.) That's the highest it's ever been!. Hopefully this isn't a fluke, but in any event I want to thank you SO MUCH for your expert advice! You've been terrific! I'm thrilled. :::..

You're right. Comcast advertises 4,000 to 8,000. My speeds aren't really fluctuating any more. They're pretty consistently low, like the last one I sent you and the test results below, per your request. I did run Spybot -- nothing. And I did call Comcast, before we started all this. They said the problem was on my end, probably my Norton Security Center, but I uninstalled that and still had the problem. I'm thinking that you're right -- there's littlemore to do other than to call Comcast. But I want you to know how much I appreciate your help. I've learned a lot from you in this trouble shooting process and am very grateful.

Hi, compuworm. Thanks for your message. You asked what ccs file I applied to the cablenut program. It was 4000/384. Regarding the speedguide program, I followed your instructions and got the following result, which is somewhat better: :::..

Thanks.

Compuworm: I did as you suggested and changed the setting to 10 base full duplex. Below is the result I got. Right before I made the change, I was getting 473 Kbps. What do you think? Thanks.

Yes, I've run anti-virus software - AVG & Norton -- as well as spyware -- Adaware and Spybot -- and I just ran xoftspy. Found a few files containing spyware, removed them, and the problem remains. I'm going to take your advice and call Comcast. You've both been of enormous help and I really appreciate it.

resopalrabotnick: Here are the data you requested on two incidents -- one slow and one faster. Thanks for any help you can provide. GENERAL DATA:: My OS is XP. I have Comcast. The advertised speed is 4

Thanks compuworm. I was able to do that with your help.

Thanks, resopalrabotnick. I followed your steps. The only one I couldn't complete was installing VanBuren cablenut settings version 7. When I unzip it, I don't know what to do with the files, because I don't see a file with the .exe extension. How do I install it? Thanks. And compuworm, your questions are not obvious, at least to me -- I haven't done any tweaking for my TCP/IP connections. How would I go about doing that? In further response, I'm not behind a router and am not sure what firmware is. Thank you both for your help. Can't tell you how much I appreciate it.

I have Comcast Cable Internet. One minuteI get speeds of around 2200 kbps. The next minute, I get 234 kbps (or less -- as low as 50), as you can see from the following: :::..

I've run a number of spyware programs -- adaware, ms spyware, spyware cleaner. Nothing. I've run cccleaner. I've defragmented. I tried turning off the computer and modem, waiting a minute, and then retrying, and then helped, but only momentarily. Comcast and a computer tech said the signal is good. The tech here said it might be the ethernet, so I replaced that -- the problem remains. He said the next step would be to reformat the drive, and if that didn't work, then to replace the motherboard. Does this make sense? Any ideas? Thanks very much. Sheila
