How to improve internet routing

I have had comcast's 6mbit/768k cable service at 3 different residences and I always run into the same situation: I need to log in to some FTP servers 4 or 5 times to get my maximum bandwidth usage. For example if I download one file at a time my average speed is 150KB/s but if I download 6 files at one time my overal bandwidth is over 800KB/s. The FTP server is located in a Dallas, TX datacenter hosted by Layered Technologies. The FTP software is not doing any throttling or anything to slow things down this much. Other people depending on their location consistantly get 1Mb/s downloading 1 file at a time. I have used FTP servers located in Seattle, WA which is near where I live and I am able to get 700KB/s on one single download. I also have the same problem uploading to the FTP sites in Dallas, where one single upload at a time starts for the first few seconds at around 15KB/s (which is slower than it should be but acceptable if I can do multiplte files at a time), but then it drops down to 1.8KB/s for the remainder of the time.

I am using Linksys equipment (I had to upgrade once previously to get maximum speeds, before no matter now many files I downloaded at one time I would only get around 300-400KB/s). Cable ModemBEFCMU10 ver 3. Wireless G broadband Router WRK54G. I have one PC on my network full time and occationally turn on my laptop or Xbox but not when downloading.

You can play with the MTU settings... perhaps tweak it to about 1500.


ive done that already but it didnt help much... I think it was defaulted to that setting too.

Too many factors involved.... I mean, Comcast's system in your area could just suck. Lot of people using a ton of bandwidth in your neighborhood, etc. They might need to improve their infrastructure.

Did you ever try doing tracert to any of the servers? For example, I live in the DC area... Comcast has most of the suburban counties except for one. But anyway, I'll find hops going through like 6-7 different suburbs within 30 mins of me BEFORE hitting AT&T's backbone.

Maybe you could play with your IP settings a bit and look for a Comcast gateway a few hops down. MAYBE that will work.
