bit of a long shot… but has anyone succesfully used a sierra 4g mifi to connect via USB (DirectIP) to a dd-wrt router? what settings worked on the router? my router is a linksys E3000 and it appears to identify the the sierra device correctly. the mifi is an aircard 762S.
there is a ‘mobile broadband’ WAN type on the router but i believe this applies to dialing up a modem device, rather than using the DirectIP interface which is ethernet-based. the DHCP WAN setting does not pick up any WAN ip address. setting a static WAN IP doesn’t work either.
i’ve tried posting on the dd-wrt forums but no luck there.
thanks for any help!
hi lotam thanks for the reply.
if i understand correctly it shouldn’t be using PPPD because it’s a directIP / ethernet interface. this is why i can’t use the typical mobil broadband instructions on the DD-WRT site, which are for how to dial a 3g modem etc.
i’ve found it may be a problem with DD-WRT switching the router back into USB mode. so i’m happy to close this thread and hope to find some solution on the DD-WRT forums.
thanks for coming back to me.
The reason I mentioned PPPD is, it was supported by all usb dongle and the directIP/Eth driver required maybe not available with DDWRT build.
So I assume PPPD was used… and ask for your log to confirm.
Anyway, if you believe the problem is on router’s USB, hope you can share good news from DDWRT forum.
i found a ‘plug and play’ solution with a modified version of OpenWRT. it works great now and the USB speeds are much better than the wifi provided by the sierra modem/router.
Seems like the firmware you are using has already built in DirectIP driver but the official site didn’t mention Sierra is supported as “Host-less Modems”… http://www.ofmodemsandmen.com/supported.html
See if I have chance to grab an USB enabled router and test the same later.
i know i was delighted with the speed test. at different times of the day the download goes up to 40 Mbit which is great.
the ‘ROOTer’ web interface shows that the sierra_net driver is identified and loaded correctly for this device, so i would guess that any sierra direct-ip modem will work with this firmware.
after all the fluting around with dial strings and loading linux modules, it was such a relief to just plug and play the modem.
