This is (slightly) off-topic, but I dare to ask anyway.

My EE background is marginal, especialy in HF areas:

I'm using I4B with an ELSA QuickStep ISA/PnP card in my router system. A few 
days ago I acquired a Aviator 2.4 wireless lan card (only 2 MBit, but hey, 
the 64 kBit ISDN connection is going to be the bottleneck). This is a PCMCIA
card that comes with an ISA card with a PCMCIA slot.

My mainboard has two ISA slots, so the soundcard had to go, and now the ISDN 
card and the PCMCIA adaptor are side by side in these two slots.

Everything is fine, but when I insert ther wavelan card my ISDN connections
starts to get flaky, after some time ending in not answered TEI messages 
and "SETUP not answered" logs from isdnd.

This wavelan card has a 2.4 GHz transmitter with 100 mW. Since there are only
two ISA slots, I can't move it further away from the ISDN card.

What should I do? Is this realy HF intereference? Would a different ISDN
card react differently?

Or is this all just coincidence and I tampered with the ISDN cabiling when
inserting the wavelan card?


Any hints apreciated,


Martin
