First off, increadibly helpful stuff. I've ready the whole thread rather carefully, and I must admit i'm familiar w/ everything short of the tweak testing and terminal / startup script based throughput optimization.

I am running:
s710a
powerbook 15" al G4 1.5 768RAM
mac os 10.4.2
medianet unlimited
*manually (via terminal) updated network settings as per your posts: (sudo sysctl -w)

et.inet.tcp.sendspace=262144
net.inet.tcp.recvspace=262144
net.inet.tcp.slowlink_wsize=108040
kern.ipc.maxsockbuf=2097152
net.inet.tcp.newreno=1

NOTE: This was after i ran broadband optimizer and SEEMED to notice a speed increase on my broadband connections right away. I reported the fastest connections in my area via BroadbandReports.Com. I'll go back and check w/out the optimizer startup script after a restart and see what I get, but right now my BROADBAND is operating nearly at the max of my possible, so that's good.

I have used a Motorola v600 tethered to my PB 15" 1.5 ghz 768RAM w/ Cingular MediaNet now for over a year and it has proven indespensible. I recently upgraded my phone to an s710a, and have been in the process of reconfiguring for EDGE capability.

I have been able to connect successfully w/ the Sony Ericsson 3G CID1 & 2 scripts, but am only achieving down: 30ish kbps / up: 9 kbps. I am in Santa Barbara, CA (full bars at current location) and have been Speed Testing at BroadbandReports.Com off of the line link server based in Los Angeles @ 2am.

dn: 33k / up: 9k report is AFTER using the terminal "sudo sysctl -w" command to update all of the above stated network parameters. these speed reports are the same as when my network settings were "un-optimized".

1. Can you advise as to what might be the hangup. I'm fairly sure its not cell related as we have very current services in this area, and I have every reason to believe local towers support EDGE. By the looks of it, I'm only getting GPRS speeds.

2. Can you advise more clearly where this /etc directory is and (sorry i'm such a layman) explain just what i need to do to create a startup script to optimize net.inet.tcp.slowlink_wsize RWIN value? As stated earlier in the thread, RMAC is not compatible w/ tiger, and BroadBand Optimizer does not adjust the slowlink value.

THANK YOU FOR YOUR INPUT!

I'm not having any luck with edge either. I've tried it on one bar and 5 bar signal strenths, and nothing. Did the tweaks, still slower than what I'm getting with Sprint. I'm afraid I'm gonna have to return the S710 and cancel service, since this was the only reason I was going to switch.

Did you try editing Ross Barkman's Sony-Ericsson modem scripts per my recent post? There's a flaw in his script that caps Bluetooth serial port transfers at 57600 bps. This flaw explains why only Sony-Ericsson users seem to be getting poor EDGE performance akin to GPRS. Motorolas and Nokias work fine, which isn't surprising since their respective Barkman scripts don't contain the aforementioned error.

Ok f1000, here goes...

I called Cingular 2nd tier and they were able to verify EDGE service availability in Santa Barbara, CA.

FYI s710 OWNERS:
There is a setting in the s710a under:
connect: data communication: preferred service:

which can be set to
1. EDGE and GSM
-or-
2. GSM only

obviously set it to option 1

Here goes:

Speed Tests: (speak-easy LA)

Un-Tweaked w/ Edited Sony Ericsson 3G CID1 script:

Modem Script Now Reads:

I'm still suspecting the modem script. Maybe something's wrong with the initialization string. I'll have to take a look at it this weekend.

Sorry this has been such a pain. I really appreciate your help...

[f1000]

Try replacing this line...

write "AT&FE0S0=0\13"

...with this line

write "AT&FV1E0S0=0&D2&C1;+CMEE=1\13"

I doubt that it'll improve your connect speeds, but it's worth a shot. If this doesn't work, I'll post a script this weekend that will allow us to better diagnose what ails your s710a.

Developement:

Last night I traveled North to Avila Beach, CA. At 3am i connected w/ the doctored modem script and tweaked network settings from your very first post and achieved something in the neighborhood of 83dn/37up off of the SF, CA server.

This morning I added your newest modem script edit (above) and tried again and got:

SF server:
Download Speed: 70 kbps (8.8 KB/sec transfer rate)
Upload Speed: 41 kbps (5.1 KB/sec transfer rate)

(i noticed the transfer started slow, peaked out at approx. 115, and then fell back to 60/70ish)

LA server:
Download Speed: 66 kbps (8.3 KB/sec transfer rate)
Upload Speed: 40 kbps (5 KB/sec transfer rate)

(peaked as high as 130, but only for a second or two, then fell to mid 50's)

So i'm certainly beating GPRS speeds now!! Probably at this point I just need to do a tweak test and optimize my settings accordingly? I don't know for sure though. Do you think I'm still not getting full bandwidth?

I'm really not sure what caused the change. I haven't changed anything since my most recent post... perhaps my serial connection is functioning properly now??

Looking forward to the diagnostic script you were going to post. I'm really curious as to what's going on here....

...mystery of the s710a...

[crozlo]

...and just now (2pm) from SLO, CA to SF, CA

Download Speed: 93 kbps (11.6 KB/sec transfer rate)
Upload Speed: 34 kbps (4.3 KB/sec transfer rate)


so i'm in the ballpark, right? how much more speed should i hope for??

This forum is a very helpful and informative collection of ideas!!

I am ready to start tweaking and enhance my S710a EDGE phone, however I simply can't connect my mac through bluetooth like a I used.
I was able to connect to AT&T's service with my T616 through bluetooth. Now I've switched to Cingular and subscribed to their unlimited MediaNet. When I try and connect using the S710a, everything goes through, but at the authentication stage it disconnects. I'M GOING CRAZY!http://forums.macnn.com/newreply.php...ply&p=2537694# I've spent days trying to debug this problem. Also, once I've attempted to connect I can no longer access MediaNet directly through the phone because it attempts to dial a roaming number instead. I have to reset the settings in order to access MediaNet directly through the S710a.
These are the Mac settings I'm using:

Login: WAP@CINGULARGPRS.COM
Password: CINGULAR1
Telephone number: *99***2# ( I have also tried wap.cingular, *99***1#, *99#)
script: Sony Ericsson GPRS CID1

This is the best forum related to my problem I could find. ARE THERE ANY AMAZING SUGGESTIONS THAT COULD HELP ME CONNECT TO THE INTERNET USING MY 15' POWERBOOK AND S710A? I am going on a road trip across the country in a few days and this would be an extremely useful tool. Thanks very much.

1. Add MEdia Net Unlimited to your account for $19.99/month (price as of 6/1/05).
    
2. Download the appropriate 3G modem scripts from http://www.taniwha.org.uk/ and install them into your /Library/Modem Scripts folder. Do not download the GPRS scripts as you will not achieve EDGE speeds with them.
    
3. On the phone go to: Menu->Settings->Connection->Bluetooth->Setup->Bluetooth: On and Menu->Settings->Connection->Bluetooth->Setup->Find Me. This will allow your Mac to find your phone via Bluetooth.
    
4. Go up to the Bluetooth menu and pair the phone with your Mac. Pair the phone to use as a modem for GPRS data. On the next screen in the setup assistant enter the following data in:
   

   Service Provider: Cingular (optional)
   Account Name: WAP@CINGULARGPRS.COM
   Password: CINGULAR1
   Telephone Number: wap.cingular

5. Open up Network in System Preferences.

   Click the TCP/IP tab

   DNS Servers:

   Leave empty!

   Select Using PPP in the "Configure IPv4" drop down menu.
   Select Off in the "Configure IPv6" drop down menu.

   Click the PPP tab

   Click PPP Options...
   Ensure that the following boxes are unchecked:

   • Send PPP echo packets.
   • Use TCP header compression.
   • Connect using a terminal window (command line).

   Click the Bluetooth Modem tab:

   Select the appropriate modem script in the "Modem" drop-down menu.
   Uncheck Enable error correction and compression in modem.
   Uncheck Wait for dial tone before dialing.

6. Add the following startup script using RMAC. Read through the thread for more details.

   #!/bin/sh
   #RMAC Startup Script
   
   SYSCTL="/usr/sbin/sysctl -nw"
   IFCONFIG="/sbin/ifconfig"
   
   . /etc/rc.common
   
   ConsoleMessage "Set Network Param"
   
   $SYSCTL "net.inet.tcp.sendspace=262144"
   $SYSCTL "net.inet.tcp.recvspace=262144"
   $SYSCTL "net.inet.tcp.slowlink_wsize=108040"
   $SYSCTL "kern.ipc.maxsockbuf=2097152"
   $SYSCTL "net.inet.tcp.newreno=1"
   
   sleep 3

Just wanted to chime in here and say that I have succesfully used my previous iBook, and now 15' powerbook with my s710a with edge speeds consistently. My settings are identical to yours except I leave the "telephone number" blank. Also, do you have the Sony "3G" script or just the regular GPRS one? That may be the source of your problem, but i'll be the first to admit, this area is not my specialty, as it's always just worked for me.

From my experiences using the Sony 3G CID1 script , it must dial the access number on it's own so I've never had to use a supplementary number. Depending upon network load I average anywhere between 100-180kbps. Im in the Charlotte, NC area.

Now that is not very close to the slowlink_wsize setting, but it is very close to your recvspace setting. Could it be that the RWIN is not slowlink_wsize? I really don't know what I'm talking about, but it seemed a bit odd.

I am definitely not a "terminal" kind of guy (I'm willing to learn), but to modify and move around the RMAC script in the GUI, you have to give yourself permissions for both /library/statupitems/ and /library/statupitems/RMAC . Then, you have to restart once, where the OS will freak out that the permission were changed, tell the OS to fix the permissions, and restart again. It's a little bit of a pain.

In my excitement, I realize I didn't relay all the important information in my last post. apologies. I promise to be more scientific from now on.
I have a Powerbook G4 with OS 10.4.1
moto v551 connected over bluetooth with full bars of service and cingular service
All the TCP/IP and PPP settings are per your first post.
The speed tests were done in Los Angeles, to the Los Angeles broadbandreports.com speed test server. and they were reported in kilobits per second.

So, how should I go about tweaking? I used the RWIN calculator (and did my own calculations based on the broadband reports FAQ) and found my optimal RWIN to be 37960. But I'm not really sure what I should be putting as my optimal speed setting. Why is your RWIN much larger?

Also, what kind of speeds should I expect to be getting? Am I doing okay at around 80kbbs down and 30 kbbs up? I was hoping (or dreaming) for double that.

Well, this has been super informative and I sure have learned a lot in the last two days. One lesson I learned the hard way was to sign up for MediaNet Unlimited right away. After just doing my tests yesterday, I already charged 40 bucks in transfer. Ouch.

Edit:
So, after I put the script back in /library/StartupItems/ and rebooted, I entered "sysctl -a" in Terminal and I got the exact same reading for net.inet.tcp.slowlink_wsize: 8192 . So now I'm at a loss. The script must not be working. Could you suggest another way (or point me to the correct instruction) on how to change these values. I really know nothing about terminal and Unix, but I follow instructions really well.

[iomatic]

Works for me. (Hopefully it's a Mac issue.) Make sure the Bluetooth port is dragged up in order under System Prefs --> Network --> Show: --> Network Port Config.

Bryan,

You're network settings are incorrect. Use these:

Service Provider: Cingular (optional)
Account Name: WAP@CINGULARGPRS.COM
Password: CINGULAR1
Telephone Number: wap.cingular

Do not enter *99 or any other such combination in "telephone number". Just 'wap.cingular'.

Try that first.

Sorry. Your modem script is also incorrect. You're using a GPRS script. You need a 3G script from here:
http://www.taniwha.org.uk/files/Son...n3G-2005-01.sit

sometimes that link downloaded empty folders for me. Try again at another time if that happens to you. I think his server is a little inconsistent from time to time. Then you'll need to read through the thread to find the edits "f1000" has posted to amend the script. It seems it closes down your bluetooth serial speeds on accident, and you need to change some code in the script to stop that from happening. Read through the thread and you'll see what to do. If the telephone number and script changes don't fix your problem, post again and we'll see what we can do.

[rancidbry]

I've tried that and everything else. It connects, but right when it trys to authenticate, it disconnects. Very very frustrating. I've been working on it for days... running out of possibilities. Any suggestion helps.

I saw the exact same thing with my Treo, but, using those settings, I changed the phone number back and forth, and I read you should move the port config up in order (shouldn't matter). Also, you have to turn on 'Dial-up Networking'. Don't know if there is that option for the Sony Ericsson. Oh yes, I turned off Airport to be certain. Connected right now.

How many days has it been since you first started trying to get EDGE speeds using your s710a before you got this result? I'm trying to figure out whether this improvement was due to my script changes or to network repairs.
