intel 536ep + data rate

mtm76 · 02-01-2005, 01:06 PM

I'm using Slack10 + kernel 2.6.9 + Intel536EP + intel-536ep-4.69.tgz. Problem is when connecting I can’t get more than 31200 bps. I already tried the identical init string like on window$, changed MTU and MRU, but still nothing. On WinXP I used to connect on 115000, with SuSE9.0 it was also faster than now… Any ideas?

why dont you try another driver, im using Intel-536ep-453.tgz and get 46666

Have run this modem on MDK 10.0, Fedora Core 2, and now SW 9.1 and all the speeds are slow. I keep hearing that it is a driver thing, but I tried it in Wxp and it was slower than my cheap amr softmodem. I have had to reduce the connect speed to 28000 to eliminate download stalls. If I speed up the modem, it chokes, and then pages AND downloads slow way down. Even my external modem and my Wxp modem are only about 4-6 kb/s. There could be other variables involved.

Right now I get about 3-5 kb/s with this init string:
AT&F+MS=V34,1,300,28800

good luck

Just one experience I had when using linux with dial-up, when I setup the modem with higher speed than I could get (I was used to set it to 11500 in Windows) it wouldn't connect or connect badly. I had to set exactly the speed the modem was designed and what I could get from my ISP.
I remember searching everywhere and asking every single person I knew using Linux and nobody could answer my problem, of course, nobody would expect such behaviour...

I actually have read similar comments that using 40x600 (I cannot remember the value)
would sometimes not work especially with kppp
I tried 115200 (i think) quite often as the default parameter instead.
That did not solve the problem so far.
I could try lower speed
I use wvdial as well as kppp in case there were a difference

Newbee question:

I tried my modem with suze 9.2 pro (it works but still AT 32000 bps).

Can I run a setserial /dev/modem and try to fix the speed that way?

Actually I did run setserial /dev/modem
and its says it is under warp_sd ("warp speed" is too high; it is not 115200
but I could not change the value; intel driver error dumped on screen
when I ran setserial /dev/536ep hi_sd (or hi_sp whatever the syntax was)
