You should really update mate. The 54gl is verry slow now and can not run the latest OpenWrt. It's not safe to have a wrt54gl in the wild. If you would like to chek out all the security bugs that have bin fixt just look at the change logs for the OpenWrt releases.
I used this for my grandma's wireless router. Both the hardware and OS are rock-solid, and 54mbps is plenty.
Still using WRT54GL, but revert it to stock firmware.
Seems that new WRT like firmwares require more ram than built 16MB.
My god! You mite as well leve your devices out in the street, with know passwords on them and ask members of the public to take what files thay would like! "Roll up Roll up! Here's all my data, fore you good people. come come, get what you want! come it'sa free for all!"
Device is connected to ADSL provider in small village and it's only one AP on 500m radius.
