Hi, I am having a strange problem with my mac and my home wifi system.

I tried to connect to my modem via the cable. It jammed my mac. I have since tried connecting to other wifi networks and no problem.. And as an added question is the fact that I have 3 computers with IP address DHCP issues can be very frustrating, they auto-assign from a router and sometimes are known to cause conflicts by either assigning the same IP, or by not issuing proper DHCP data.

My Leopard IP address was different this morning than what it was last might when it last worked.

When I do that it just chooses the same number I put in. But this morning, after my Leopard had been put to sleep last night with everything working fine, when I woke it up it had a different IP address, one beginning with I think. Google DNS of 8. If your ISP will swap it out as leased equipment that may be worth a try, particularly if the problems are intermittent and effect random computers at seemingly random times.

This was very useful. I went down two of the advanced list yesterday and got it working. But today l lost wifi again. This time nothing works. All of this can be helpful for avoiding potential channel conflicts, or when troubleshooting wireless problems. Try to set different channel for your AirPort wifi because of bluetooth.
