I want to extend the WiFi-range of my new (4th-gen.) Time Capsule to the other end of the house by use of my old AirPort Express (probably 1st gen. - only 802.11b/g-mode).
I read some of the threads here in the community and thought that I had understood how to to do that but now my Time capsule keeps switching between steady green and yellow flashing lights. On AirPort utility 6.0 I see that apparently my internet connection is supposed to be lost whenever it goes to the yellow light. I had no such troble before I changed the configuration to "Participate in a WDS". Before it was on "create a wireless network".
To summarize what I did:
Using AirPort Utility 5.6 I first switched the Time Capsule (which is connected to the modem and to my iMac via ethernet) to the "Participate in a WDS network" and clicked "Allow this network to be extended". Unter the "WDS-Menu" I set it to "WDS main" and clicked "Allow wireless clients". Afterwards I entered the MAC-Adress of my AirPort Express under the WDS Remotes. Then I updated the Time Capsule. (it is still set up to also transmit signals in the 5 GHZ / n-mode under a different automatic channel, but this should not affect the AirPort Express, since it does not receive any signals in 802.11n - does it?)
Afterwards I connected my AirPort Express via ethernet to the Time Capsule and also set it to "Participate in a WDS network". The Radio Mode is on "802.11b/g compatibel" and it is on the same channel as my Time Capsule. Under the WDS-Menu I set it up as a WDS-remote, allowed wireless clients and entered the MAC-Adress of my Time Capsule as the WDS-Main.
Now I try to run the setup and every 10 seconds or so the yellow light of the Time Capsule lights up.
Does anybody have an idea what might be wrong?
