56k not connecting as fast as under win2k

[liquidfx13]

I have an HCF Conexant Modem running with the drivers from linmodem.org. I was just in win2k for the first time in months and had to set up my modem to access the net while in win2k and noticed that it's connecting/transferring at a faster rate than under linux. all the settings seem to be the same is there something that i am overlooking in linux that could make the connection faster or is there a something about windows that makes the modem faster that i am unaware of. it's a noticable difference in speed.......

Linux:
connect at 31.2kbps
average download speed: 2.8kbps

Win2k:
connect at 45.2kbps
average download speed: 4.5kbps

anybody have any ideas for things that i would want to check into? Could this be an issue with the MTU setting or someting like that?

I connect under linux using Kppp, but have set up wvdial and netconf in the past for my dialer.......

thanks in advance

Must be something your ISP requires. When I was using win 2000 pro (using XP pro) I got much faster dwnld speeds in Linux with kppp that I did in windoze. Maybe if you check all of their requiorments against yours...

Yep, I get faster speed using Linux then Windoze!

You could try the Tweaking your Modem NHF (http://linuxnewbie.org/nhf/Modems/Tweaking_Your_Modem_with_MTU_and_MRU.html).

When I used a 28k moden on a noisy phone line I found small mtu and mru values worked best for me as fewer packets had to be repeated.
fI don't remember for sure, but I think I settled at around 192 for both values.

Incidentally, the information I used had originally been posted by Sensei. (!)

thanks i will give all those options a try......the thing is that all my options are set the same as under windows in Kppp.......off i goto give the modem tweak NHF a go.....

anybody else who might have different suggestions is more than welcome.....


UPDATE:

I don't the MTU/MRU packetsizes are the problems as was suggested in the tweak modem NHF.......here's the output that i get from several tests run.....

Default MTU: 1500
--- neteze.com ping statistics ---
21 packets transmitted, 20 packets received, 4% packet loss
round-trip min/avg/max/mdev = 159.967/183.955/219.709/13.533 ms

MTU of 750:
--- neteze.com ping statistics ---
10 packets transmitted, 9 packets received, 10% packet loss
round-trip min/avg/max/mdev = 479.456/497.680/599.964/37.089 ms

MTU of 1200:
--- neteze.com ping statistics ---
10 packets transmitted, 8 packets received, 20% packet loss
round-trip min/avg/max/mdev = 219.987/304.956/439.708/86.982 ms

***NOTE**** these are just pinging my ISP......but if i were to ping say yahoo.com the results while higher show the same characteristics

anybody got anymore suggestions on this? could really use the help and/or advice here.......

I had a similar experience when I was using a dial-up modem. I found that in Linux if my browser's user-agent pretended to be IE5.5 on Win2k, data-transfer was much faster. I also noticed that my ISP was redirecting me to a different home-page if I used Windows, or a Linux browser whose user-agent claimed to be IE5.5. Naturally they wouldn't comment on this but I have my suspicions on what was going on - pushing non-Windows users through a slower router or something like that.

Try using Konqueror and setting the use-agent string to IE5.5, Win2k (in browser/setup), to see if this improves things. You never know!

I have a cable modem now, and although the same redirection occurs, the effect on speed is marginalised.

Check for newer drivers, those Conexant Linux drivers are updated almost every day. My Conexant modem gives (when í'm home) faster download speed than Windows but difference is not big. Windows gives about 4,3-4,4kb/s (v92), Linux gives about 4,3-4,7kb/s (only v90).

I would think it is a driver issue as well. In windows you are getting a v.90 connection while Linux is using a 33.3 connection.
