Help,What to do with RWIN????,

bertski · Post by **bertski** » Thu Apr 12, 2001 6:24 pm

I recently lowered my RWIN setting to 30660. After running this test, it seems that maybe I should increase it by A LOT(513920 on the high end and 64240 on the low end)Both are at least double my current setting.Is this correct and what would be the suggested RWIN setting??I have W98, ADSL connection via Bellsouth.Can I get higher speeds as I currently get about 1200 kbps.Any help would be gratly appreciated
TCP options string = 020405b401010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.

Default Receive Window (RWIN) = 30660
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 30660
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 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 1226.4 kbps (153.3 KBytes/s) @ 200ms
Your RcvWindow limits you to: 490.56 kbps (61.32 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 115 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

lobo what patch sets it to 255552...isnt the cablenut patches for PPPOE dsl??? do they have any patches anywhere for PPPOA dsl?? I
ALSO have bellsouth adsl with ppoA..I have tried the pppoe dsl cablenut patch for win 98 but, as with the speedguide patches my download speed is ALWAYS 85..or 700-750kbs..no rwin change has affected it ever..
nor mtu for that matter...I've tried all..I wish I could find a PPPoA patch!!

ps I wish I knew how he got 1200kbs speed!

I have a P-II 350 PC and have DHCP bridged connection. So ,what should I do, leave as is or change it to the much higher settings recommended here?
Thank you

Thats what tweaking is all about, if your happy stay where your at, if not try something else, I would

What would you suggest I try re-setting the RWIN to?? I use Drtcp to adjust it.

Lobo · Post by **Lobo** » Thu Apr 12, 2001 7:22 pm

You need adjuster no matter what, it comes blank, default values are being used you enter what you want or download something that will put values in box

It's a lot easier than going into registry

Your help is greatly appreciated!!!

I don't know enough about dsl to venture a guess, but they may in cable and dsl forum ask them their, maybe they have the answer, sorry

By all means do as you wish, but you have been told

Again, thanks
