Okay, after messing with a few settings, (namely the MTU and RWIN) I finally got a load of green bits, instead of red. Below are the results.

TCP options string = 020405b40103030301010402

MTU = 1500

MTU is fully optimized for broadband.

MSS = 1460

Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 513920

RWIN Scaling (RFC1323) = 3 bits (scale factor of 6)

Unscaled Receive Window = 64240

RWIN is a multiple of MSS

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

256960 (MSS x 44 * scale factor of 4)

128480 (MSS x 44 * scale factor of 2)

64240 (MSS x 44)

Ok, results below,

TCP options string = 020405640103030101010402

MTU = 1420

MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.

MSS = 1380

MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 71680

RWIN Scaling (RFC1323) = 1 bits (scale factor of 2)

Unscaled Receive Window = 35840

RWIN is not fully optimized (even though it is a comparatively large number). The unscaled RWIN value is lower than it should be, which can affect your connection to some servers. Also, RWIN being close above 65535 does not justify the header overhead of scaling. You might want to use one of our recommended RWIN values below.

For optimum performance, consider changing RWIN to a multiple of MSS.

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

507840 (MSS x 46 * scale factor of

253920 (MSS x 46 * scale factor of 4)

126960 (MSS x 46 * scale factor of 2)

63480 (MSS x 46)

Ok, done the stuff requested.

Results below.

I am getting a tad suspicious that it always caps at 30kbps, both upload and download.

Out of curiosity, on my router setup screen it says:

  Data Rate

  Downstream/Upstream                    576Kb/288Kb

I take it that this is what it is "supposed" to be. I have never seen these figures change, so it looks like they're sent, not detected, but I'll keep my eyes on it.

Ok, set it back to 1500

clicked on the link and this is what showed...............

TCP options string = 0204058c01010402

MTU = 1460

MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.

MSS = 1420

MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 65535

RWIN Scaling (RFC1323) = 0 bits

Unscaled Receive Window = 65535

Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.

For optimum performance, consider changing RWIN to a multiple of MSS.

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

522560 (MSS x 46 * scale factor of

261280 (MSS x 46 * scale factor of 4)

130640 (MSS x 46 * scale factor of 2)

65320 (MSS x 46) 

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

Your RcvWindow limits you to: 2621.4 kbps (327.675 KBytes/s) @ 200ms

Your RcvWindow limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 116 hops

TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349) = 00000000

And yes, it is 1500, though this says 1460.....not sure whats going on there.

okay, have set it to 5000, only problem is that tweaktest has stopped working, think i've gone over my allocated "5 tests in a few hours."

Router & Modem all in one. Can't bypass it (or at least i don't know how.)

Thanks 4 swift reply.  Below is the new Tweaktest URL.

Ok, Firstly, I'm gonna apolgize for the length of this, but i'll be damned if i'm gonna miss something out.

As you can see, my connection speed is pants. Always has been. Hopefully we can fix this together.

I am also a member of the tweakxp forum, as well as a few others, and have tried a few things to no avail, so all got set back to the original settings awaiting (expert) advice from here. (p.s. I have tried VB's updated cablenut settings and no joy)

I have basically read through all this forum follwing all the tips, and losing more and more hair, until i figured that i really don't have a clue what else to do, so I just followed the instruction given by VanBuren (as you can see below).
