These are my results from Speednet.com
How do I know if I am using PPoE DSL broadband or not.  I know that I have DSL (verizon), but any advise would be great.

MTU = 1492
MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
MSS = 1452
MSS is optimized for PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.
Default Receive Window (RWIN) = 624640
RWIN Scaling (RFC1323) = 4 bits (scale factor of Cool
Unscaled Receive Window = 39040

For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
511104 (MSS x 44 * scale factor of Cool
255552 (MSS x 44 * scale factor of 4)
127776 (MSS x 44 * scale factor of 2)
 63888 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 24985.6 Kbps (3123.2 KBytes/s) @ 200ms
Your RcvWindow limits you to: 9994.24 Kbps (1249.28 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 55 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)

Consider lowering ur rwin to 127776, and raising your mtu to 1500, if you have a router you probably wont be allowed to raise mtu value.

Van Buren,
I did all of that before. Thanks.
I used Cablenut, and even EventID (I currently have maximum concurrent half-open connections at 25. I will lowering my rwin to 127776 but I can never seem to raise my mtu to 1500.  How do I know what I am using to connect to the internet (PPPoe, modem)?
I will let you know the new totals in a minute.

As a side note, by the way, Van Buren is like a guru from what I have read and I thank you all in advance.

I ran a traceroute on speed.imagehouze.com and post here are my results.
Your current bandwidth reading is:

1.49 Mbps

which means you can download at 190.34 kB/sec. from our servers.

56 Kbps    dial-up    
256 Kbps    DSL/Cable    
768 Kbps    SDSL    
1500 Kbps    T1/Cable/DSL

4. What speed do you have against http://testmy.net and http://nitro.ucsc.edu/ also download this Tracert and Ping program(made by php) and click on check.bat.  When it's done, copy and paste the results in your post.

looks like your maxing out, i assume your cap is 1.5 Mbps down

try setting your DefaultReceiveWindow to 128000 for faster web browsing

edit: or even lower, until speed goes down

try 96256 aswell
