I have Spark Max Fibre broadband. I am using an ASUS XT8 router. The fastest upload speed I get from the router is 40 Mbps.To test this I used a factory reset router connected to the ONT and a single computer by wifi. The speed test is directly from the router.

I recently had a problem sending 40 g diagnostic data to Apple, a couple of dropped connections and an interminable wait.

Download is 800-900 Mbps.

PBTech reviewed the router and said it works fine and showed me a printout of 250 Mbps upload speed.

I reported this problem to Spark and they said not our router, not our problem.

I would appreciate any help in resolving this issue please:

Could it be the ONT? Chorus don't seem to accept direct troubleshooting issues.

Could it be the modem anyway?

Should Spark try harder?

Thank you

Guy

I see you tested using Wifi. What results do you get testing with an ethernet cable?

Sorry I didn't make it clear. Test was built in modem test, directly via cable to ONT. The wireless was only so I could tell the modem what to do.

That's testing offnet. What do you get using speedtest.net to a Spark speedtest server from a wired device?

Talkiet:

The OP wrote "The speed test is directly from the router." so I assume it's an internal test tool, not from a LAN client.

To @schnopp:

Which server is the router using for testing?
Can you plug a computer directly to the ONT and test to the Chorus Lab instead?

@schnopp I see the screenshot posted before my reply was in.

Why use the Primo server? Why not use a Spark server for testing?

I assumed that modem would provide purest result. It chose the out of town server.

Testing from wired connected device via local servers only gives me 40Mbps upload which is what got me started.

Thanks. Certainly seems to be a connection problem.

Is this a limitation of the router?

What speed do you get if you simply plug a device into the LAN and run a speed test (no wifi)

Other than that, take up @cbrpilot offer

The test is via wired. I only mentioned wifi because I had a single connection to allow me to control the router from my laptop.

Tim's suggestion is similar to my question before "Can you plug a computer directly to the ONT and test?"

This would eliminate the router as a problem.

Take your laptop, plug it in with an Ethernet cable into a LAN port on your router, fire up speedtest.net site and post results

if you laptop/pc does not have a ethernet port then this obviously isn't going to work
