Awesome, thanks! I will do some tests tomorrow morning and try it every 5 degrees or so and test if I can get a reasonable upload speed again.
There are some caveats to that process, but a lot of help in this thread and
the B593 one.
Since it turns out that you do actually have the B593-s601, which is 2300MHz/TDD capable, you have the additional variable of the frequency band : your modem/router could be on the Telkom 1800MHz/FDD band or the 2300MHz/TDD band, and there's no real way to know from the Web UI which it's using.
Do you have a suggestions for a router that I can alternate between 1800 and the 2300 band range and which can take the two antennas?
The successor to the Huawei B593 is the B315, which is identical in many respects but is 2100MHz (Cell C) capable. It also has the newer API which works with "The Toolbox" and hence can be forced to use one or the other frequency band (1800 or 2300, in Telkom's case). You might also consider the Huawei E5186 which has the same API but is LTE-A capable. Check out the
B315 and
E5186 threads for more details. All these modem-routers have the dual antenna sockets required for LTE, yes.
I'm at a loss for a solution if the direction method does not work other than buying another router.
It's always good to optimise your own signal arrangements in terms of signal strength, signal quality and connection stability; but at the end of the day, your throughput is still determined very much by the performance of the particular station you get service from. Changing stations and/or frequency bands often helps, but it isn't a panacea for blistering speeds. See
this post for an example of what I mean :
Station / Result
A RSSI/RSRP/RSRQ=-53/-80/?; DL/UL=61.2/8.2
B RSSI/RSRP/RSRQ=-52/-81/-8; DL/UL=11.2/7.8
C RSSI/RSRP/RSRQ=-54/-81/-7; DL/UL=30.0/7.2
D RSSI/RSRP/RSRQ=-47/-73/-6; DL/UL=22.9/9.1
E RSSI/RSRP/RSRQ=-53/-79/-6; DL/UL=76.5/4.5
F RSSI/RSRP/RSRQ=-48/-74/-6; DL/UL=58.6/8.5
G RSSI/RSRP/RSRQ=-48/-75/-6; DL/UL=28.3/8.2
Happy hunting!
