BIG BIG problems

[lanceifer]

now i am home from work i have moved my cordless phone across the room and i moved my guitare and amp to the other side of the room i moved my roughter about a foot and a half away from my modem and my connection seams to be bouncing, all over ????

[trogers]

Is there some electrical equipment installed on the other side of the wall or perhaps your neighbour below you? If it involves neighbours, I would rather relocate my comp against the wall with a window. Then at least I am sure my comp is not affected on 3 sides.

[lanceifer]

on one side of my computer there is a phone jack on the other there is an electrical outlet, which way the wiring runs i don't know, i am in the bacement so i have no neibers for about 300 ft,

[lanceifer]

d-link is giving me an rma so i get a new roughter they think my roughter might be failing but i don't think that is the problem as i get the same symptoms wiht the di-624 and wiht the di-604

[lanceifer]

also i noticed when i moved my roughter from the wall it made my connection worse

[lanceifer]

is there a way to set all my windows settings back to default???,  or to remove all my net work things with out having to redo my whole windows set up?????? mabee iof i just reset every thing back to default and start from scratch it would be easyer to figure out??????

[trogers]

To restore to default XP Windows registry, use TCP Optimizer.

You can dowload it from this link:

ok i still don't understand network limited and recever ,imited, what is limiting them??? , and network flow control also, could some one exsplain thies to me????

Windows sets RWIN to a default value of 17520 Kbytes and it has a function that can negotiate and adjust RWIN value to a max of just over 64000 Kbytes. This is ok if our subscribed bandwidths are not much higher than 2 Mbps and latency not exceeding 300 ms. Occasionally, some problems may occur when the negotiations and auto adjustments fail.

But for bandwidths of 3 Mbps and more, optimum throughput can never be achieved.

If say, your subscribed bandwidth is 6 Mbps, you will unlikely to achieve even half that bandwidth with Windows default.

Using the RWIN formula,

RWIN = bandwidth x latency divided by 8 (bit) = ________ Kbytes

So if RWIN = 65000 and latency is 200 ms

Bandwidth = 65000 x 8 / 200 = 2600 Kbps

This is why we need to tweak to get optimum throughput and speed.

ok i have moved every thing around in my work area, and installed a new video card which ment i had to move my network card down a slot and here are my new tests.

MTU = 1500

MTU is fully optimized for broadband.

MSS = 1460

Default TCP Receive Window (RWIN) = 64240

RWIN Scaling (RFC1323) = 0 bits

Unscaled TCP Receive Window = 64240

RWIN is a multiple of MSS

Other RWIN values that might work well with your current MTU/MSS:

513920 (MSS x 44 * scale factor of

256960 (MSS x 44 * scale factor of 4)

128480 (MSS x 44 * scale factor of 2)

64240 (MSS x 44) <-- current value

bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 2569.6 kbps (321.2 KBytes/s) @ 200ms

Your TCP Window limits you to: 1027.84 kbps (128.48 KBytes/s) @ 500ms

estimate = 41.24 based on packet size = 11Kbits, RTT = 270.13msec, and loss = 1.0E-6

The theoretical network limit is 41.24 Mbps

The NDT server has a 101.0 KByte buffer which limits the throughput to 2.92 Mbps

Your PC/Workstation has a 62.0 KByte buffer which limits the throughput to 1.81 Mbps

The network based flow control limits the throughput to 1.85 Mbps

Client Data reports link is 'T1', Client Acks report link is 'T1'

Server Data reports link is '10 Gig', Server Acks report link is 'Ethernet'

any other settings any one can think of to help out????
