Lately, running Speedtest on my 100mbps cable connection is only getting about 15mbps when the Speedtest app chooses the Optus (and most other) servers. If I force it to a Telstra server, it shoots up to 60-70. Historically, I've always got pretty close to 100 using Speedtest. What could cause this problem? I do think downloads generally are much slower than they used to be, for example when downloading from Apple. But it confuses me that Speedtest to Telstra servers seems much better (albeit not as fast as it should be).
That's definitely unusual.
Have you spoken with our 24/7 Tech team to have this looked further into to see what might be causing this?
Additional troubleshooting can be found here, and is recommended before reaching out to them as it may resolve the issue.
Thanks for the replies. I had actually got on to support (via chat). I had already turned the modem off and disconnected the cable, to no effect, but support asked me to factory reset the modem. Surprisingly, this seems to have worked! I still can't figure out why Speedtest to Telstra was different to Speedtest to Optus before though. Anyway, I will continue to monitor the situation.
Thanks for the update @sddawson, glad to hear it's now working.
That is strange, were they able to shed any light on this?
Thanks @sddawson, I'll pass feedback on about this.
