mnosteele...any suggestions?

Here are the answers to the questions in your help thread...

1. Done

2. Cable

3. RCN - 1500/800

4. 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) = 64240
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 64240
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)

bandwidth * delay product:
Your RcvWindow limits you to: 2569.6 kbps (321.2 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1027.84 kbps (128.48 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 57 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 01011100
Precedence (priority) = 010 (immediate)
Delay = 1 (low delay)
Throughput = 1 (high throughput)
Reliability = 1 (high reliability)
Cost = 0 (normal cost)

5. 976/332

6. 98SE

Your thoughts, if you would, please. Thank you.

Your settings look perfect but your speed isn't up to par, it might be RCN, I know Duzmor here at SG had a terrible time trying to get his connection up to speed with RCN. Try the following and see if it helps.

Also do the following:

1. Install the vtcp 386 patch (http://www.speedguide.net/files/vtcp386/236926USA8.EXE).

2. Open IE and select tools - internet options - connections - LAN settings, make sure NOTHING there is checked.

3. 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 (http://forums.speedguide.net/showthread.php?s=&postid=643301#post643301)).

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), anything checked in red is spyware and safe to remove.

:) :D

Thanks for the reply, mnosteele. I have already done all the things that you mentioned (I "lurk" around this forum quite a bit :D ), so I'll have to assume that it was an RCN thing. I just noticed that my connection was running a little slower than normal last night, so I ran some tests and decided to ask for your opinion. Thank you again for your response.
