Just got upgraded from 1024 Kbps to 3000 Kbps, but still getting 1024 speed.

TCP options string = 020405a00103030001010402

MTU = 1480

MTU is optimized for Windows XP PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.

MSS = 1440

MSS is optimized for Windows XP PPPoE DSL broadband. If not, consider raising your MTU value.

Default TCP Receive Window (RWIN) = 63360

RWIN Scaling (RFC1323) = 0 bits

Unscaled TCP Receive Window = 63360

RWIN is a multiple of MSS

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

506880 (MSS x 44 * scale factor of 8)

253440 (MSS x 44 * scale factor of 4)

126720 (MSS x 44 * scale factor of 2)

63360 (MSS x 44) <-- current value

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

Your TCP Window limits you to: 2534.4 kbps (316.8 KBytes/s) @ 200ms

Your TCP Window limits you to: 1013.76 kbps (126.72 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 58 hops

TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349) = 00000000 (0)

I have tried every rwin value listed here ^^^^^^^^ with no results. Started top to bottom. Running 63360 now.

I have wireless. with 3000 Kbps, how fast should I be able to download a 1 MB file ? thanks for any help.

See if your MTU can be higher than 1480.

Try the following with the TCP Optmizer (www.speedguide.net):

General Settings tab:

Custom settings - check

Modify All Network Adapters - check

network adapter selection - your NIC

MTU 1492

TTL - 64

TCP Receive Window -63888

MTU Discovery - Yes

Black Hole Detect - No

Selective Acks - Yes

Max Duplicate ACKs - 2

TCP 1323 Options:

Windows Scaling - uncheck

Timestamps - uncheck

Advanced Settings tab:

Max Connections per Server - 10

Max Connections per 1.0 Server - 20

LocalPriority - 5

Host Priority - 6

DNSPriority - 7

NetbtPriority - 8

Lan Browsing speedup - optimized

Then select "Apply Changes" and reboot to take effect

Are you located overseas? Your Latency is rather high. Your MTU is fixed at 1480. You can raise it to 1492 using below:

http://www.raspppoe.com/

In the mean time use TCP Optimizer and do the following for MTU 1480 and latency of 200 ms:

General Settings tab:

Custom settings - check

Modify All Network Adapters - check

network adapter selection - your NIC

MTU 1480

TTL - 64

TCP Receive Window - 126720

MTU Discovery - Yes

Black Hole Detect - No

Selective Acks - Yes

Max Duplicate ACKs - 2

TCP 1323 Options:

Windows Scaling - check

Timestamps - uncheck

Advanced Settings tab:

Max Connections per Server - 10

Max Connections per 1.0 Server - 20

LocalPriority - 5

Host Priority - 6

DNSPriority - 7

NetbtPriority - 8

Lan Browsing speedup - optimized

QoS: NonBestEffortLimit - 0

ToS: DisableUserTOSSetting - 0

ToS: DefaultTOSValue - 240

MaxNegativeCacheTtl - 0

NetFailureCacheTime - 0

NegativeSOACache Time - 0

LAN Request Buffer Size - 32768

Then select "Apply Changes" and reboot to take effect

I'm not overseas. Right in the good old U.S.A. Like I said I have wireless. I'm about 1 mile from the tv station tower where i recieve the signal from. I have a direct, unobstructed sightline to the tower.

Here is a post regarding a possible fix on wireless interference:

http://www.testmy.net/forum/index.php?topic=11877.0

Once your latency gets back to normal, use TCP Optimizer with the following changes:

TCP window size - 63360

Window scaling - uncheck

If wireless interefence is minimal, your speed should be 80-90% of advertised and time to download a 1 MB file should be within 3+ seconds.
