I use a 900 MHz radio system using a flat antenna pointed line of site to a tower. The tower is about  15 miles away. The provider advertises upload speeds of up to 4 Mbps and up to 1 Mbps upload. My download is as follows:


::::::::::.. Download Stats ..::::::::::
Connection is:: 591 Kbps about 0.6 Mbps (tested with 579 KB)
Download Speed is:: 72 kB/s
Tested From:: http://www.testmy.net/
Bottom Line:: 11 times faster than 56K you can download 1MB in 14.22 second(s)
Validation Link:: http://testmy.net/cgi-bin/get.cgi?Test_ID=GQEBW516X


My upload was 160 Kbps. Does anyone have an experience with this kind of system or any suggestions on speeding it up?

That's the test he means btw, nice copy'n'pasting VanBuren.

Edit: btw falco, you're either being ripped off, or your ISP is blatantly lying on their maximum speed. You are not even close, and you'll never get close...

  Welcome to the  site I hope you enjoy and if your speed can be improved there are people here that will be happy to help.......... Yep I gotta agree with RTB your ISP is telling you something that they wont even come close to.. There must be some fine print somewhere...... the good news is that it may be possible to improve your speed...... Keep visiting and tell your friends about testmy.net

Here's the first test.

Tracing route to testmy.net [67.19.36.6]
over a maximum of 30 hops:

  1    91 ms    10 ms    16 ms  10.4.1.2

  8     *        *        *     Request timed out.
  9     *        *        *     Request timed out.




From 5 to 30 I got request timed out. I tried the tweak tester but it wouldn't give me the results. The URL of my provider is  http://www.cclnetworks.com. on their home page is where they make the claims on their blazing speed. This is still way better tha 28.8 on dial-up.

here's the other test.
SpeedGuide.net TCP/IP Analyzer


TCP properties for IP = 216.123.241.61 ()
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)
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) = 17520
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 17520

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
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: 700.8 Kbps (87.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 280.32 Kbps (35.04 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON
Time to live left = 117 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000
 

  A Default receive window(RWIN) at 17520 is a default setting  set by Windoze unless you made it that value.... which Im sure you may be aware of but if not...........

Bad news! It is noticeably slower after installing those registry values from cablenut. Here are the results:

Here's the results from the other test:

Any ideas? Can I go back to the defaul settings before cablenut?
