Hi all

The reason I post this as a "challenge" is because I know it can be done, as I have done it before with the exact hardware I have in front of me, many years ago. However, I can't remember how it was configured (and I remember it took me ages to figure out!). I have since hard reset the hardware, and now want to get this working again. So I post this for help, but also as a "fun" challenge which network people might enjoy.

If this kind of post is not welcome here, forgive me.

Hardware:
1 x Cisco 1242AG-E-K9 Access Point
1 x Cisco Aironet 1121-G-E-K9
1 x Cisco SG 300-10P (should be irrelevant)
1 x home ISP router

What I want is:

--- or --\ or --/ = wired
>> << = wireless

PC1 --\
PC2 --- Home Router --- Cisco AP >> << Cisco AP --- Switch --- PC4
PC3 --/

Note (may be relevant, not sure) I don't necessarily need any PCs on the WLAN.

I'm posting this as a challenge, but I'm not being a d*ck about it, I'm trying to figure this out myself, so I will post any solution or partial solution I come up with as I'm doing it. And hopefully any solution posted by me or by anyone else will go on to help others trying to do something similar.

Thanks all for your help!

Without reading the details of your AP there is no way to be sure. In general a AP is not designed to do what you are asking for. One if not both the devices must support the ability to run as a client-bridge. This is exactly the reverse of what a AP is. You also likely will need to support WDS to allow mulitple mac addresses to pass when yo put a switch behind. WDS is not part of the official standard and sometime commercial AP do not support it.
