Step Two: Configure Router

So why do we want to duplicate the functionality of the E355?
Well, it seems to be limited to five devices, as I mentioned in an earlier post that I have massive problems with that, I don’t want to have to juggle tech to some arbitrary limit. Also, I’d like to support more services at some point (media streaming perhaps)
Like all the 3G dongles I’ve seen recently, they initially show up as CD-Roms. Then the “drivers” switch them over to being the actual device. In this case a Micro SD Card reader and a USB CDC device, in this case a USB ethernet port.
Initially I configured the WR703N as being a Wi-Fi repeater, and that appeared to work. Alas, the WR703N has a tiny, tiny amount of internal flash, and it’s easily filled up. So some devious things need to be done.
So, what we need to do is boot, twiddle the 3G modem so the SD card shows up, switch over to that and bring up the other services.
The initial packages I installed (to the best of my memory, as I was doing this late at night) were:
kmod-usb-storageblock-mountusb-modeswitch-datausb-modeswitche2fsprogskmod-scsi-generickmod-fs-ext4
Of course the (32Gb) SD card was partitioned and formatted by a prior fdisk installation thus:
sda1swap (255Mb)sda2/overlay (4Gb)sda3/home (27.Gb)
Well, after bricking router “B”, I plugged the dongle into an Ubuntu virtual machine; alas, OpenWRT doesn’t have “rndis_wlan, rndis_host, cdc_ether, cdc_ncm” which is required … okay, it has cdc_ether but none of the other modules – so development has stalled for now.
