First of all....im running a Gateway laptop...its a school laptop. Its my moms laptop she got for her work. No anyways i use it through a dlink 624 and a DPC2100 Series Comcast modem at home. Im not running any bg applications/tray tasks or any other computers on the router...and no televisions are on. The wiring is all fine...i have a very short cable from the wall socket to the modem...i noticed a very big difference of performance with longer wires (around 500kBs slower) Ok so anyways im using cablenut cable & dsl 4000.ccs
1. Windows XP- P2P Tweak installed.
2. Comcast 6/384 plan.
3. Cablenut... dsl & cable 4000.ccs also tried 10000.ccs but no difference in speeds.
TCP properties for IP =  ()

MTU = 1500w
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled Receive Window = 64240

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 10278.4 Kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 Kbps (513.92 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 51 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00100000 (32)

Precedence (priority) = 001 (priority)
Delay = 0 (normal delay)
Throughput = 0 (normal throughput)
Reliability = 0 (normal reliability)
Cost = 0 (normal cost)
Check bit = 0 (correct, 8th checking bit must be zero)

DiffServ (RFC 2474) = CS1 001000 ( - class 1 (RFC 2474). Similar forwarding behavior to the ToS Precedence field.

Okay apart from that im getting great speeds on testmy.net and other tests. Here is what it comes down to. I have nothing running except this pc on the router....when i do downloads...my speeds are usually 200-300....they start at like 1mB/s  and then rapidly go down to 200. Nothing ever dls faster then that. Im sopposed to get like 700+kB. I have tried many diff sites/servers and i also have tried no tweaks....4000.ccs and 10000.ccs.
So how can i get my real speeds? I also tried bypassing the router but it still does the same thing.

The speedtests are showing good speeds.  Most often, when you cannot download files at speeds anywhere close to your cap, it is because of the server you are downloading from.  Keep in mind that the server is uploading at a certain speed, and likely uploading the same file to other users.  It is also possible that in the network between you and the server there is a bottleneck which restricts speed.  There is also the physical distance from you to the server.  It may also depend on the software you are using.

There are a lot of factors.  You may rarely see your actual download speed when dl'ing files over the net.
