Troubleshooting Wavelan wireless, RH 7.2

Troubleshooting Wavelan wireless, RH 7.2

Post by Chris Thor » Fri, 09 Nov 2001 05:38:44

Trying to break the Evil Empire habit here. Next step in that
process is to get my RH 7.2 laptop up on wireless. Not working
so far. I must be overlooking something incredibly dumb & obvious.

Have two Orinoco Wavelan Silver 802.11b cards. First one is
in a W2K machine. Second is in a dualboot RH7.2/Win98 machine.
No other cards are inserted.

W2K to W98 works fine. W2K to RH7.2, well, they ain't talking
to one another. They *see* one another over the air, but no more.

Ping fails from either side. Both machines can ping themselves
but not the other. TX/RX appears to show packets are being *sent*,
but *not* received. This is true in either direction.

The Orinoco Client Manager for W2K has a "Link Test" option.
Invoking that indicates that the radio connection between the
two cards is "Excellent to good".

The link test from W2K also picks up the station name of the
RH7.2 machine, so packets are being sent and received.

The RH7.2 machine is also receiving the MAC address of the card
in the W2K box, according to iwconfig.

Both machines are set to channel 10, network name "JUPITER".
Client Manager confirms this on the W2K side, and iwconfig does
the same on RH7.2.

Both machines have been assigned IP addresses in a local 10-block.

Encryption is turned off on both sides until I get wireless up.

W2K machine is set for "Peer to peer" mode, RH7.2 is "Ad-hoc"
mode, which I assume is the same thing.

Here's the spec from both sides of the divide:

W2K machine --
station name "CALLISTO"

RH7.2 machine --
station name "GANYMEDE"

And relevant dumps from both machines, Windoze first:

Those "link quality" readings under Linux are perturbing. I have
been combing the documentation trying to figure out if that means
there's no effective throughput. They haven't made that very clear.

Anyone's assistance would be quite gratefully welcomed.

1. Orinoco Wireless Silver & RH 7.2

Hi, although I was able to get my Orinoco Silver wireless card to work
on Redhat 7.2 by manually changing my ESSID on /etc/wireless.opt
however, I've been wanting to use the driver package supplied by
Orinoco for the card, which appears to be newer than this one, but I'm
having trouble installing it.

Basically, when I run:  "make config"

I get a:      "make: *** No rule to make target 'config'. Stop"

I know this is probably something stupid, but although I'm familiar
with the old ./configure make, make clean, etc processes, I do not
know what to when this happens because of my inexperience with the OS.

After these steps what follows is basically running the "Build" and
"Install" scripts but cannot get to those if without accomplishing
this first.

If anyone can shed some light my way I'd greatly appreciate it...
