Tekki, why do you keep suggesting this DefaultTOS value of 127? That is not a valid number.

j79zlr

A router is no different than a software firewall, it is just that the software is on and resource usage is done by the router.

And yes ZA is terrible, is causes a lot of problems, after you work on/fix PC's you just notice these things. Norton Antivirus is terrible, NIS is even worse. McAfee is a ...

That is just the registry cleaner, only the full jv16 power tools program has the expiration problem.

225kB/s * 8 bits/byte = 2000kbps

You are right at your caps, stop complaining

AS far as I have experienced, Linux is very good at self tuning. There are some tweaks that can be applied, but none have given me any noticeable increase.

Most of the settings are in /proc/sys/net/ipv4/

The only thing I do is turn timestamps off

echo 0 > /proc/sys/net/ipv4/tcp_timestamps

j79zlr

adding another switch should help load balance as well

router > switch > 4 PCs

I believe QoS really only helps with LAN bandwith not WAN

Group policy settings are global, all users (including administrators) are affected. If you want to enable a group policy for a specific user I have a list of all the registry values, then you must log in as that user or load their user hive, and apply the change.

What did I do?

My page would only calculate a RWIN that high if you had a latency of 385ms which is probably way to high.

j79zlr

Check your display properties, settings tab, advanced, it can be in there somewhere. I have an ATi card, it depends on your drivers as to where it is, but it should be in there somewhere.

j79zlr

Your AGP should be set to 4x as that is your mobo's chipset maximum and your vid card would handle it. Make sure it is set in the BIOS.

download Cablenut and try these values:

What OS?

j79zlr

OK, I seen Conservative Swap File tweak and XP, that tweak is absolutely invalid. Changing anything is sys.ini is pointless since XP disregards that file.

As far as page file size, you should never set the minimum value to anything less than the amount of RAM installed. The page file is not the ...

j79zlr

Try using these cablenut setting, you shouldn't have your receive window that large regardless of the connection, btw your upload is 1Mbps, with possible maximum download of 25Mbps, your download is not nearly tat, if we can't get your dl speeds up, your setting should be adjusted. I would try and ...

What OS are the PCs running?

j79zlr

college networks are highly congested, little you can do. You get those high speeds in the summer because they aren't using the bandwith.

j79zlr

but why would you want to mess with the MSS, it should be MTU-40 since the TCP/IP header is generally 40 bytes.

j79zlr

RASPPPoE or most PPPoE clients use 8 bytes for authentication in the header of the TCP packet, since you are not allowing it that 8 bytes, you can't connect ;)

XP's built in PPPoE client uses 20 bytes, so its MTU is 1480.

Cable or PPPoA does not send authentication information so it has an MTU of ...

Try these, McCoffee gave you the XP/2000 settings:

BcastNameQueryCount = 1

Linux's TCP stack is very good at self tuning. I personally leave all my linux/unix systems at default.

j79zlr

oops, ok I see you are running XP,

download Cablenut (Direct download) and try these values:

DefaultReceiveWindow = 921600
DefaultSendWindow = 128000
DisableAddressSharing = 1
InitialLargeBufferCount = 200
InitialMediumBufferCount = 480
InitialSmallBufferCount = 640
LargeBufferSize = 819200 ...

j79zlr

what OS are you using?

j79zlr

I replied to your post at DSL nuts, the analyzer reports that low RWIN because the RWIN increases to a point during transfer. The analyzer doesn't send enough data for the RWIN to react.

j79zlr

those timeouts are because DSLnuts.com has ICMP blocked with their new server. Try a tracrt to google.com.

j79zlr

I am not a moderator here, nor am trying to be, but in my experience as one on other boards, most forums arent too keen on referrals to other forums.

DSL BB, I have never seen you actually help anyone, just refer them to DSL reports which is the exact opposite.

jpsimon, please do what mnosteele ...

j79zlr

standard guarantees 384, up to 1500, should get closer to 1500 unless you are very far from the CO, so you would be about half of RR download speed.

j79zlr

It seems that your problem is an over congested network, and not much you can do about that.

j79zlr

NOT ALL PCS / ROUTERS CAN HANDLE SUCH TWEAKING especially when you have an ISP that sucks

???

That makes no sense. Details please.

Cablenut works just fine for DSL, anything saying otherwise is wrong, yes these setting can affect DSL users but is very rare

MaxFreeTcbs
MaxNormLookupMemory

that said, tekki, do you have a point? Most people come here because their connection is not ...

j79zlr

Also try changing these settings:

InitialLargeBufferCount = 200
InitialMediumBufferCount = 480
InitialSmallBufferCount = 640
LargeBufferSize = 819200
MaxFastTransmit = 64000
MediumBufferSize = 150400
MaxConnectionsPer1_0Server = 10
MaxConnectionsPerServer =8

j79zlr

First, your ping is not really tweakable. With Cox cable, try setting your NIC to 10Mb half duplex, and change the default receive window in cablenut to 384000

j79zlr

Its really easy, read here http://forums.speedguide.net/showthread ... adid=32417

always in kilobits, 300KB down as you said you were getting above is 2400kbps, that is pretty fast. Most business dsl just has a better upload, not too many providers offer DSL above 1500, but some do.

j79zlr

Always set the pagefile's minimum size equal to the amount of RAM you have, regardless of what anyone says, XP addresses out memory on your hard disk even when it doesn't use it, that is why its necessary. Anyone who claims that they set theirs to zero and get a huge increase is either misinformed ...

j79zlr

you might to change your DefaultSendWindow (2nd setting) to 49152

Won't really make much difference though, your speeds are awesome.

j79zlr

This doesn't make sense. Unless you have a T3 line to your house, the limit is not going to be the router, it is going to be your connection speed. If it is OOL (10000 down) then a router with a 10Mbit WAN side will still be able to handle it. All 7 PCs are not going to be able to use full bandwith ...

j79zlr

McCoffee's settings are a little off, follow the rest of his thread, but use these:

DefaultReceiveWindow = 192000
DefaultSendWindow = 16384
DisableAddressSharing = 1
InitialLargeBufferCount = 200
InitialMediumBufferCount = 480
InitialSmallBufferCount = 640
LargeBufferSize = 819200
MaxFastTransmit ...

j79zlr

Those speeds are very good for your connection, 556 out of 600 and 110 out of 128, you're not gonna get much better.

j79zlr

you cant judge speed on things like KaZaA or BitTorrent, since they are dependent on the people you are connected to. Use something like a Speakeasy speed test or a large ftp download from a reliable server. You have to reboot after making changes with cablenut.
