LTE latency issue in Riverclub Sandton

Hi,
I am having a strange issue with my TM LTE connection. The connection to the Internet is very unstable with the connection flapping between normal connectivity to nothing.

I did reboot the modem, powered it off completely for a few minutes, and have also removed sim. The strength signal is 3bars are per normal with the data 'blue' light blinking as per normal. The WIFI light also blinks.

It almost seems to me that it is a "latency" issue. Let me explain; when loading YouTube for example, the video takes extremely long to "buffer". It can play for 5 to 10 minutes with no issues, streaming perfectly. But if it stops, it takes very very long to start playing again. Similarly on Facebook, it can take extremely long to update and load the page. But works once loaded. Even Whatsapp is an issue. It can take very long to connect, before I can send or receive messages.

The weird thing is 10% of the time it works perfectly, and the rest of the time there are issues.

Anyone else experience anything similar ? Does this point to a hardware issue on my side, or a TM issue ?

Can you put us in the full picture? Signal strength (edit: sorry, see you did say 3 bars), distance from the tower, RSSI, RSRP, RSRQ, speed profile from early morning to late at night.

Is this a new problem?

It's a new problem. Started a week ago.
Speed profile is completely random. On the speed test app, I get anything from "download failed" or "cannot ping server" to 20Mbs. I re-test back to back and it changes. Time of day doesn't make a difference. I will need to to check the router for the other details.

Your signal is not great, but still acceptable. Are you sure it is currently using LTE when it happen?

One way to deal with issue is to force LTE-only or 3G-only connection and see how signal is changing and whether it helps in each case.

The other step helping finding out possible problem is to check how it works on Ethernet cable when WiFi is disabled and compare when is enabled again.

See, that is not normal. I get very distinct speed patterns for peak and off peak. I never get "latency failed" messages. (But I have seen these a few times over the past year)

Your issue is not related to congestion. This is an LTE issue at the tower you are using.

It is also very possible your tower is in the process of being upgraded.
