Sad Bizarre Linksys NP100 problem 

Forum: PCMCIA Network Adapter Issues
Date: 2000, Apr 23
From: Larry Carter lcarter

I get normal cardmgr startup (i.e. good double beep) and all my logs/config files look good, yet the card will not talk to the lan (dongle lights do not even light up). EXCEPT that sometimes I can get the card to work if I remove it and re-insert it. The card will work fine, network lights glow, I can ping the other boxes on my net, but eventually (I have not been able to get a consistent time frame), the card just seems to shut off (lights go off). cardctl says all is fine, ifconfig looks good, I can ping my local IP but not anything else on the network! This card works great with Win95 as the only other difference. I have tried it in both slots and at different IRQ's (even though I know 3 is free) to no avail.

Here are the only things I can think may be the problem.

1. My i82365 chipset is one that is not listed anywhere (Omega Micro) and may be the problem (or part of it).
2. The card is going into some kind of low power state that Linux can't get it out of. However, I have had the card "turn off" in the middle of pinging other boxes on the network so I don't think this could the problem.
3. The NP100 is "dumbing down" to 10Mbs. Though I doubt this would be an issue (I do have a dual speed hub).

It is driving me nuts. I really, really need to have networking on this system and I cannot seem to figure this out. Does anyone have any pointers?

Here are the details:
Laptop: CTX EzBook 750cs, P150, 32MB
OS: Caldera OpenLinux eDesktop 2.4 (SuSE 6.3 seems to have same problem)
NIC: Linksys (Network Everywhere) NP100 PCMCIA
PCMCIA: tried both 3.1.8 and 3.1.14

Here is /var/log/messages output for cardmgr:

everything else is as installed from 3.1.14.
