Editing a config file as root

[ForScience]

I have a cheapo tablet, an Eken M009S, on which I'm running Uberoid 10.1http://techknow.freeforums.org/universal-uberoid-wm8650-1-5-5-honeycombmod-v10-1-t1317-820.html. From previous attempts on an older version of Uberoid I know I need to modify a configuration file to get the wifi link to work; however, in the newest Uberoid version I'm unable to do so.

I start File Expert and it requests root access, which I grant; then I find the config file, tap it, and select to edit it using Ted. Ted, however, refuses to save.

I thought it was a permission problem, so I went in the terminal emulator, ran "su" (I have some Linux experience) and tried to edit the config file with vi, but it opened it as read-only. Then I tried chmodding the permissions, and chmod reported the whole filesystem is read-only.

I've no idea how this read-only filesystem weirdness actually works, but I must find some way of changing that config file. Any ideas?

Thanks.

I havent used file expert in a while but is there an option to mount /system as rw? its normally ro. In es there's an option for that I know just right next to the one for root mode.

Where would I find this option? I don't know what you mean by "in es"...

If you use Root Explorer instead, a big button labeled 'Mount as R/W' appears up top when browsing directories in which you dont have root access
