Does anyone know if there is such a thing as a super admin login for a Huawei B315s-607 modem/router?

 

Something similar to the HG659 Admin/@last8digitsofserialnumber?

 

I'm looking for additional config options that aren't accessible via the default admin/admin.

 

By design, if you supply one of these routers with:

 

     

  1. an active 4G SIM connection, and
  2. a working internet connection via the eth4 LAN/WAN port, with the eth4 connection mode set to "Dynamic IP", 

 

the router will always prefer the ethernet connection via eth4.

 

It will only flip over to packet data via the 4G SIM connection if you remove the cable from the eth4 WAN port.
We have an application where we want the B315s router to do the reverse.

 

ie it should always use the packet data connection via the 4G SIM, and only failover to the internet connection via eth4 WAN port if the 4G packet data connection stops working.

 

Reason for wanting to do it that way is due to much higher speed available via 4G connection, on RBI, versus a really slow ADSL modem upstream connected into the eth4 WAN port - the latter should only be used as the backup, not the primary connection.
Is there any higher level admin login that allows us to set the connection priority for different types? Or an alternate firmware with slightly different featureset? (needs to still work with VF RBI SIMS & plans).

 

It seems likely I'm not the only person to have ever wanted to do this in NZ, let alone the rest of the world, but my Google-fu fails me...

I don't think the B315 has such a 'super-login' and neither is it designed to work as a Dual-WAN router with 'failover'

 

I did have a similar setup to what you want with a B315 on Skinny Broadband for high-speed use (streaming etc) and a low speed ADSL connection (sub 5 Mbps) as backup. The B315 WAN/LAN port was set to 'LAN only' with all traffic set to use the 4G connection as primary. All non critical clients were simply set with the ADSL modem as the 'default gateway' (as were all other clients in a backup situation)

 

Your other option is to get a proper Dual-WAN router and connect the B315 and your ADSL modem to that and let it do all the connection/failover work.

Your requirements are beyond those on offer in a very low end device (which is what the B315 is).

@tangerz, thanks but setting manual def gateway on every client...

 

That could work if it was only a couple devices, but this particular site is a remote office where roaming users will connect on ad hoc basis ie frequent client device changes...

 

I have found the failover method from eth -> 4G to be "relatively effective" in testing, but as you say it's not really a proper dual-WAN router. Got any good device recommendations then, where I can set the default desired "Primary" connection? Ideally, it would be one that has it's own internal SIM slot, rather than using those flaky USB modems that end users can knock out or try to swipe for their own use...

I was starting testing with the B315, since it is what VF supplies, and they are our company ISP.

You just need to be aware you can't use a Spark, Skinny or VF FWA SIM card in 3rd party hardware.

Thanks, those look quite pricy...

 

I can only find NZ-based list pricing for the older -E and -A2 variants, which seem to be 3G-only, so I can only imagine what the -M pricing is like for newer 4G variant...

Please pardon my ignorance, I don't know what the FWA acronym stands for, or what the implications are?

FWA - Fixed Wireless Access

 

All it means is that all providers lock the SIM card for their FWA products to the router it came with (all in NZ are the Huawei B315 variants now if I'm not mistaken) so you can't just take the SIM out and use it in an alternate 4G/3G router, it just won't work.

 

In your original post you indicated you were using Vodafone RBI so to use that you're stuck with the Huawei B315s-307 for your 4G access. What you need to achieve what you want is a Dual-WAN router, or better yet an xDSL/Dual-WAN modem/router combo. Something like this:

 

https://www.asus.com/nz/Networking/DSL-AC52U/

 

You then connect your xDSL line to the Asus DSL port as one WAN and connect from a LAN port on the Huawei B315 to the Asus WAN port as the second WAN. Then you can go into the Asus configuration to setup the Dual-WAN failover as you want, eg 4G as Primary connection, ADSL as Secodary connection.

 

You'll end up with double NAT on the 4G connection but since all 3G/4G connections are CG-NAT anyway this shouldn't be a problem.  Also turn off Wi-Fi on the Huawei so all connections run through (and are therefore managed by) the Asus. (You'll also need to make sure the Huawei LAN is using a different IP range to the Asus LAN as the Asus can't have the same IP range on both LAN port and WAN port!)

Thanks for that explanation - all makes perfect sense to me.

 

Appreciate the tip on the Asus devices as well - I didn't realise they could select the connection priority for the WAN connection mode, that's handy to know, cheers :)
