Airport Express B/G : problems with manual IP configuration?

Question

I don't know when it started, but I think it has something to do with one of te latest systemupdates or airport firmware updates.
Configuration :
- Airport Express N : only N, bridge mode, IP manual (192.168.1.7), roaming with Extreme N
- Airport Extreme N : only N, bridge mode, IP manual (192.168.1.35), roaming with Express N
- Airport Express B/G (older one) : B/G compatible, bridge mode, IP manual (192.168.1.8), no roaming, just stand alone.
All the airports are wired connected to a 10/100 switch.
No internet configuration on these airports, I'm using a separated router, also connected to the switch.
Problem : The airport Express B/G dissapears from the network : from time to time not visible in the airport utility program, from time to time not visible in iTunes (airtunes). In spite of these problems, he is always visible in the airport network menu. An IP ping works just fine.
When I change the IP configuration of the Airport Extreme B/G from manual to DHCP, there is NO problem anymore.
No problems with the Airport Express N an Airport Extreme N.
Are there other users with the same problem?
Thanks in advance.

Answer 1

question: i below what should i do ?
1) put a cable from my cablemodem to the airport extreme bs;
2) put a cable the airport extreme bs to the airport express bs.
Yes on both. Your network configuration would look something like the following:
Modem > (Ethernet) > \[WAN port] AEBSn \[LAN port] > (Ethernet) > AX
do i have to reset the modems and are there any setting i should be aware of ?
Yes, it's always a good idea to both reset both base stations and, after doing so and before configuring them, perform a complete power recycle of your network equipment.
So in this case ...
o Power-down the modem, AEBSn, AX, & computers. (Order is not critical.)
o Reset both the AEBSn & AX. (Again, order is not critical.)
o Power-down each base station after performing a successful reset.
o Power-up the modem; wait at least 15 minutes.
o Power-up the AEBSn; wait at least 10 minutes.
o Plug-in the AX; wait at least 5 minutes.
o Power-up your computer(s).
o Use the AirPort Utility to reconfigure both base stations as required.
