I just upgraded from a Motorola Surfboard 3100 to a Surfboard 5100. Will I need any different setting in cablenut? It seems a lot faster just from the new modem. Can I get my settings just to check? Thanks.
TCP properties for IP =
Browser/OS = Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Notes: Read the Analyzer FAQ if the above is not your IP address.
TCP options string = 020405b401010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
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:
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 (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 = 53 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)

Then select "Apply Changes" and reboot to take effect.
1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need.
2. Open IE and select tools - internet options - connections -
LAN settings, make sure NOTHING there is checked.
3. ALWAYS connect your modem via ethernet (NIC) and make sure you have the latest drivers for your NIC from the manufacturer. Set your NIC duplex mode to 10mb half duplex for Cable, for DSL it is ISP dependent unless you are using a router, if so then set it to 100mb full duplex for both Cable & DSL (the instructions are in my Help & Tips link). If you are using a router make sure you have the latest firmware.
4. Clear your temporary internet files.
5. Power cycle your modem, unplug it for atleast 15 seconds.
6. Download and update then do a scan with SpyBot http://beam.to/spybotsd & Ad Aware http://www.lavasoftusa.com/support/download to remove any spyware then install and update SpywareBlaster to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES.
7. Make sure you do the faster web page tweak in Read1st link.
8. If you have Zone Alarm as a firewall uninstall it then visit Zonelabs.com for further instructions on removing it's left over junk.

If I use a large TcpWindowSize of 102200 and turn my Tcp1323Opts to 1, I lose about 1000 kbps downloading and my windows take a few seconds to start loading. I found it better to keep it at 65535. I have only 40 RTT avg. Would this have anything to do with it?

Its the duplex mismatch Im wondering about.
