The Huawei B593 LTE discussion thread

Hi!
I have some questions about this unit, as I'd like to use it in an unconventional way (I think).
This router, in fact, would manage a secondary connection in the office I work in.
I would like to change the actual router with this one. The router is then connected to a switch, the switch (obviously) manages the cables for the pcs attached to lan and to some servers.
So... my aim is to set the connection to "mobile" when the main DSL connection is down (yes, we experience some downtimes). Questions are:
- is it possible to deactivate the LTE connection and let the router act as a normal, "dumb", router when I don't need LTE connection?
- how can I switch from one kind of connection to the other? Is there a physical switch to deactivate/activate the sim card or do I have to login into the administration panel?

These are the simple questions... sorry for my rough English and greetings from Italy!

Hi hypfra - welcome to the forum!

It sounds to me like you want a device (a router) that is able to switch between two different internet services, for example DSL (fixed-line) and LTE (wireless). You want to do this either manually (with a switch) or perhaps automatically, such as designating one service as primary (DSL?) and having the connection "fail over" to the other service (LTE?) when the primary service fails. Correct ?

To be honest, I don't think the B593 can do what you want, because it does not have a separate WAN port.
To explain : The "switch" part of the B593 moves local LAN traffic between the four LAN ports, while the "router"part of the B593 routes traffic between any of those LAN ports and the LTE WAN, when that traffic needs to go "off-LAN". In effect, the B593's WAN port is "buried inside" the B593. The only WAN that the B593 can route traffic to, is the one provided by the LTE connection. If the LTE part of the B593 is turned off (which is possible, yes) then the B593 can only act as a switch for LAN traffic. It can't act as router any more, because it has nowhere else to route to !

To do what you want to do (or at least, what I think you want to do), there are a few options:

1) You could get the type of ADSL modem router that has provision to connect a 3G or 4G wireless device as a backup device. Most often these ADSL routers come with a USB slot that can take a wireless modem, usually 3G, but 4G models are becoming more common now. You can designate one connection (let's say DSL) as the primary connection, and have the router "switch over"to the wireless connection when the primary one fails. Have a look at the Netgear DGN2200M as an example.

2) You could get the type of DSL router that - in addition to the port that connects to the DSL (phone) line - has a second RJ-45 ethernet WAN port. This allows you to connect a backup device (for instance, a 3G or 4G modem, or another DSL modem) to the secondary WAN port, and have the router automatically "fail over"from the primary DSL connection to the secondary WAN port.

3) You could get a device called a "dual-WAN router" that has a multi-port switch (usually at least 4 ports) and two WAN ports. You would connect your two modem devices (like a DSL modem on one port, and a B593 LTE modem on the other port) so that the dual-WAN router can "fail over" from one to the other. Have a look at the Linksys LRT224 as an example.

Although the dual-WAN router approach is more complicated, it has some advantages. First, you can use any kind of internet connection device, as long as it has an RJ-45 ethernet "output" port - it could be a DSL modem, an LTE modem, a cable modem, a fibre modem ... or anything else new that comes along. Second, dual-WAN routers tend to provide much more flexibility in how you route traffic between the two WAN ports. "Failover" is perhaps the simplest routing algorithm, but there are also equal-split, proportional load-balancing, priority, etc etc.

Incidentally, I use exactly this type of arrangement : a dual-WAN router with a simple DSL modem on one WAN port, and the B593 LTE modem on the other port. The only difference is that in my case, the "slow" DSL modem acts as the backup for the fast LTE modem :D

Hope this is of some help to you!
 
Anyone know if this R1499 deal is still available at telkom direct stores?
 
MTN Sh@relink B593

I got this router on Tuesday. At home I only get 2 bars of signal, sometimes 3. It will not connect in LTE mode, only 3G. So I moved it to my office, where it gets 5 bars signal, but still will not go on LTE, only 3G. The SIM is marked LTE and both areas are in the LTE maps, on the MTN site.
Is it possible that the SIM was not activated correctly? Or perhaps a problem at MTN?
Also : is this router network locked? I would like to use it on other networks as well when I travel.

Even at 2 bars on 3G it is about 10x the speed I get on ADSL, so it was worth getting it.

If you have the black MTN-branded Sh@relink from MTN, then it's probably the B593u-12 sub-model (see here). This model only does FDD, so in effect it is "locked" to network operators who use FDD-mode LTE in the frequency bands it supports. In SA, that means MTN or Vodacom, for now at least. It won't do Telkom LTE (TDD), for instance.
The MTN-branded Sh@relink may be further network-locked to MTN, but I'm not sure about that.

Have you checked that your B593 isn't perhaps set to 3G-only mode (apologies if insulting your intelligence!)
If it is set to allow 4G, but isn't doing so, then perhaps it's worth checking with your service provider whether that SIMcard really is LTE-enabled.
For what it's worth, when I upgraded my SIMcard to an LTE-capable one (for testing a B593!), I still had to phone MTNSP to get the actual LTE service provisioned on it.

Thanks to whoever found this deal a while back. Just to let you guys know the deal is still on. Just make sure you don't go to a telkom mobile store as they still have it listed at R3500 on prepaid. The normal telkom home store has the discounted version.
 
It is set to Auto. When set to 4G (LTE) only, it never gets a connection. And yes, it is the black u-12 sub-model. The lady at the shop confirmed that it was LTE enabled. Maybe I should also contact them myself to confirm.
Why I ask about the network lock is that I am supposed to be able to search for connections on the same page where the LTE only setting is, but it does not find any others. I know for a fact that TM, VCom and Cell-c are available here.

Update : I did finally get it to search for connections. It lists MTN 4G as "available" and MTN 3G as "registered". When I click the register button, with 4G selected, nothing seems to happen and it still will not connect on 4G

Your general technique sounds OK, but check the steps against this post and this one just to make sure ?
If you're following all the right steps and it still won't register or connect, then I would start to suspect that the SIMcard isn't provisioned for LTE.

Apart from calling your service provider, try and get access to another known LTE-enabled device (like a friend's Galaxy S5 smartphone) and check that the SIM connects properly and indicates an LTE connection in that device.

Thanks, jcheek, the steps are what I did, only the u-12 sub-model's screens are very different to the model you are using. I believe my SIMcard is the problem and will follow up on that. But first I will take it on the road to a different part of town in case something is wrong at my local tower.
 
Hi Guys

Thank you for a most informative thread. I decided to upgrade my Telkom Contract and took the B593 because of this thread. Initially I set it up with the included paddle antennas and got three bars. I then started experimenting and noticed something interesting. I left the paddles in place but set the router to internal antennas. I then got 4 bars but the moment I remove the paddles it drops back to three bars. I tested this three times and got the same result. This was the last speed test results.

Test Date: 25 Oct 2014 10:34 AM
Download: 40.20 Mbps
Upload: 4.67 Mbps
Ping: 39 ms
Connection Type: Wi-Fi
Server: Centurion

I am very happy with the result considering that this is the router as taken out the box.

This was still the case on 26 Oct.

PS. I see Rodga beat me to it.
 
R1499 at Telkom Direct Musgrave Centre in Durban. A friend picked one up for me yesterday :)

Yes, the u-12's firmware (v100-something, I think) is very different, and in some respects, better.
The s-601 has different firmware (v200-something) which was greatly "simplified" and in the process, lost some functionality.
Hopefully you were able to figure out the equivalent steps in the u-12 firmware.

I believe my SIMcard is the problem and will follow up on that. But first I will take it on the road to a different part of town in case something is wrong at my local tower.

Good plan - let us know how you do.

Your experience with the built-in antennas versus the supplied flat whips, is very much the same as mine, and - I suspect - probably the same as many other users'. The subject has come up a few times in the thread (also see here).
The B593's built-in patch antennas are actually pretty hot!

Nice speed test result, btw. :D
 
I am having a very strange issue with my router. Occasionaly, the data connection will just disconnect despite the lights on the router indicating it is connected to the network. I need to then unplug the router and replug it in order to get connections going again. Very strange since my router is barely six months old
