Cannot set bit rate in Debian
Hello,
I have two laptops each running Debian in adhoc mode. The 2 are using the Intel Centrino Wireless Drivers. However, when I do "iwconfig" I get a bit rate of 0Mb/s, which makes no sense. Can't make sense of it at all.
I try to set it manually to 11M but it will not change. Does anyone know what this happening.
Very desperate to get this to work.
To the moderators...... Please do not send me any more messages about posting in other threads. Several moderators have sent me messages and I get it !!! ok. Please keep the thread open for people to reply.
Thanks,

|

Well, the first question is: have they established a connection? Otherwise, there's no point in playing with connection speeds.

Problems setting bit rate in Debian
Matir,
Yes I have. I have tried to ping the other machines and they
are receiving the packets. What could be wrong ?

I wonder if this might be a bug of some sort with respect to Ad-Hoc networking. What kind of speeds are you getting?

Matir,
The bit rate says 0kb/s . Obviously it must be sending stuff right ?

Unless I'm off base, ad-hoc mode is kinda like a wireless crossover cable right? So do both computers show 0Mb/s or just one? It could be just a problem with the driver reporting and maybe even setting speed. You said you can ping, is the link otherwise functional in that you can share files or whatever it is you are trying to do over the connection? Matir made a good observation, maybe in ad-hoc mode the driver won't report speed due to a bug? Is there a network you can get on in normal mode to see if it reports/sets speed correctly when connected to that?

Obviously, the connection is not really at 0k/s, as no data would be sent. I agree with Darin: both ends the same? check another connection? Also, what kind of real speeds (i.e., perform a file copy) are you seeing? Real throughput is likely to be ~5Mb/s.

Guys,
You are right. Is there anyway for me to determine what the transfer speed is, any command which would output this information !!
Thanks,
Pia
