Further to my previous post:

K3 on e4200 seems to not have ext modules for mounting ext2 (in particular) to mount ext2 formatted USB sticks. It woks fine on 2.6 but not on K3. This is also the case on r30016

So that leaves me with either K2.6 and abilty to mount ext2 on usb but no QoS to throttle bandwidth on guest wifi OR K3 with QoS working fine but no mounting ext2 USB and subsequently no optware.

Try other file system such as fat or fat32. I believe they are still supported on r29739 for e4200. If you must use ext2, try older build such as r29193.

Just to clarify: ext2 IS supported on r29739 K2.6 just not on r29739 K3.x which is odd.

I know it is odd as I always thought that ext support is native. I think you have found that ext2.ko is not in /lib/module/3.10.101/ and I believe you need either ext2.ko or ext4.ko to get ext2 support. My guess and I am not talking on behalf of the developers, there are not enough memory space (8M for e4200) to hold everything and somehow ext2.ko is being taken out.

BTW, have you tried fat or fat32? It should be OK for optware purpose.

OK I can confirm that r29193 does have ext2.ko and can mount ext2 FS. It's only 63 kb so it's not huge:
62 -rw-r--r-- 1 root root 63424 Mar 2 2016 ./lib/modules/3.10.98/ext2.ko

I'd really like to see it re-included in later/current e4200 builds.

I haven't tried fat32 as it doesn't preserve some of the attributes that ext2 does but I haven't ruled it out yet. I expect it will work I just didn't know it would work with optware.

Just to continue the slightly off topic discussion on r29193, throughput seems to be a bit erratic and slow but that my just be my son updating games ATM.

Thanks for your help.
