The Huawei E5186 LTE-A discussion thread

New owner of a B5186 LTE-A Telkom router.
Welcome to the forum!


I am keen to understand what a good quality signal looks like using the signal quality metrics, i.e. RSSI, RSRP and RSRQ in the router's diagnostic page or via the app. I am in the process of considering an external Poynting antenna and need to assess whether my current RSSI of -65 to -70db is good, bad of indifferent, and will benefit from the additional capital investment.
For a very quick-and-dirty guide, just use the table that appears here. (It appears in quite a few other places, too).

For a bit more background to what the stats mean, you may find this post helpful. The info there mostly relates to the Huawei B593, but the general concepts are the same. In addition to the 3 metrics you mention, the E5186 also measures and displays SINR (Signal to Interference & Noise Ratio, where higher is better), which the B593 doesn't. The E5186 seems (subjectively) to be able to achieve a higher RSRQ than the B593, which seems to max out at -6dB under ideal signal conditions.

Hi guys, I was wondering if someone can give me a hand. A friend of mine has the huawei lte cpe e5186 and wants to know if he can limit the speed of each person connected to it? He has a small B&B and allows free wifi for the guests but he's recently had a few guests abuse the privilege. Thanks for the help in advance!

Not. He/she need a real router with static IP in Huawei DMZ, on cable connection.
 
Does anybody know where you can buy the E5186 outright to use with the Cell C giga packages?
 
Ok so i scanned this whole thread. I currently have the Asus DSL-AC68U ADSL router which gives me load of control over devices & users. If I use the E5186 for internet instead of ADSL, I want to still use the features of the Asus. Do I just connect them via the ethernet ports and then fiddle in the LTE router settings? i.e.

[My Lan (wired & WiFi)] ----- [Asus] ------ [E5185] <----> [LTE]

Sorry, I am afraid you can use Asus as Ethernet switch, not a router, because ASUS do not have WAN Ethernet port, only LAN ports.

Not sure if I understand correctly. The ASUS is an ADSL router with phone jack and 4 ethernet ports. Does it need a WAN Ethernet port? Is that something different? Meaning upstream WAN-side port?

You're looking for a scheme similar to the one shown here, but for that to work, you need access to the WAN side of the router inside the Asus DSL-AC68U. Looking at the specs for that device, it unfortunately doesn't have the WAN side brought out onto an RJ-45 port.

Yes, on both questions.
Some xDSL routers have a separate WAN port allowing you to use them in this way. On some others, one of the LAN ports is a dual-purpose port that can be configured as a WAN port.
Unfortunately it looks like the the Asus DSL-AC68U has neither.

Thanks for clearing that up. That means no LTE for me then. Apart from selling the ASUS and getting something that offers similar control. Or wait for fiber as the ASUS is fiber ready.

WAN support is a pretty important feature in a 'combo' router these days, IMHO. Flogging the Asus (in favour of something that has WAN support) is one option.
Personally I prefer 'modular' devices, ie separate modem (fibre and/or LTE), separate router and separate WAP, over all-in-one devices.


Or wait for fiber as the ASUS is fiber ready.
To be honest, if it doesn't have a WAN port, I can't really see how it is 'fibre-ready' ... ?
Check out whether a firmware upgrade might enable one of those 4 LAN ports as a dual-purpose LAN/WAN port.

In the SA context (certainly in Telkom's case), the fibre network operator often makes use of an ONT (Optical Network Termination), which 'converts' between fibre and ethernet and feeds into the WAN port of a separate downstream router. So you'd still need a downstream router/switch with an WAN port.

That Asus looks like a good device, but rather specific to the xDSL scenario.
Given that you'll be moving to a different technology (fibre or LTE), I'd suggest flogging the Asus xDSL 'combo' device and getting a 'pure' router that (by definition) has a WAN port. That router won't care whether you plug a R250 ADSL modem, an LTE or LTE-A modem, or a fibre modem into the WAN port. It'd be a good investment in your future :D

LTE rocks, as does LTE-A (if you can find it!). No need to wait for fibre - enjoy the benefits of LTE for a year, or however long it takes for fibre to become a reality in your area.

I have also been looking as this is ideally what I would like to do. Cell C are only supplying the B315 on their contracts anyway, but I would prefer to buy outright and be able to shift to another mobile provider if they offer better performance and/or value.
 
I have recently purchased and installed the 5186 at my flat in Rondebosch. I am only getting speeds of about 3mbs to 10mbs. I am looking at getting an Antenna but since I am on the second floor and there are buildings all around me (i cant install on the roof) I dont know if it would help my situation.

Which antennae would people recommend and would it work if I cannot install on the roof

Thanks in advance
 
Referring to this :

Some info on somebody who was able to do exactly that on an Asus N14-U :

If you have an Asus ADSL router you can use it for fibre.

All I did was upgrade the firmware on the router and changed some configurations to change a LAN port to a WAN port and its working fine. This is with a ASUS N14-U so I'm sure more expensive Asus routers should be able to do the same

Hey pdh123 !

For some general guidelines, you can have a look at this post and follow some of the links to other posts and antenna-related threads from there on. The info there is specific to Poynting antennas and written more around LTE than LTE-A, but the general principles will be the same for LTE-A and for any suitable antenna system.

As regards your specific situation, it sounds like you will be relying mostly on reflected signals rather than direct ones, so it's hard to say what benefits you might get. At a very rough guess, I would say that any gains you get with an indoor antenna will probably be quite modest. What may help is to get your antenna system - whether that's the one built into the E5186, or an indoor external, or an outdoor external system - close to a window, or better still, just outside. Usually getting the antenna system outdoors already helps quite a bit. For instance, you may be able to get some benefit from a scheme like the one shown here. One-piece dual-polarised antennas like the Poynting XPOL-0001 and XPOL-0006 are quite low-profile and you may be able to get away with an installation that is "external" if not actually on the roof.

Whats the best deals currently for the e5186. It's for a friend,i'm looking at the cellc giga 100,but then he has to buy the device separate.

Any contract deals that is currently a good deal?
