Internet speed plummeted after VM work

venables
Up to speed

Hi

I live in area 7, and VM completed work in the area yesterday (3rd August).  Today, speedtest.net is reporting anything from 100Mbps to 180Mbps.

I'm on M600, and generally before this was getting 580-620Mbps regularly.  Yes, it is school holidays, but in the past it has only dropped to 300Mbps or so for brief periods, and this has been all day.

I have rebooted the router, used a direct LAN connection to 2 laptops, and also a connection via an Asus XT-8 in modem mode, and all report the same speeds.

Since the reboot there have been no timeouts, and the upstream log shows this:

Channel Frequency (Hz) Power (dBmV) Symbol Rate (ksps) Modulation Channel ID
1 39400000 49.8 5120 64 qam 4
2 46200000 49.8 5120 64 qam 3
3 53700000 50.5 5120 64 qam 2
4 60300000 51 5120 64 qam 1

Downstream shows this:

No post RS errors exist.

Any ideas?  I've done remote tests using the website and all come back ok.  Nothing internally has changed other than I had a couple of days not using my laptop

Edit> as a quick addition, upload speeds are consistent.. 40Mbps all the time.

Power off hub for 2mins and connect a PC to the power on in modem mode to get internet unplug replug Ethernet cable may be needed and do a speed test.
---------------------------------------------------------------

Yeah, done the test in modem mode after a reset.

I used to run in modem mode but now run my iot network from the VM hib and my own network is behind that. The xt8 is on the DMZ port

all runs very well and before used to get full speed

Maybe a case of more people downloading and VM eyes on the money then on the network.

---------------------------------------------------------------

Possibly but the contract said guaranteed download of 300Mbps.

Engineer visit is booked for 15th due to landline issues as well, all since the VM work in the area, so hopefully both will get resolved. The forum member on the landline call said there was an upstream power level issue on the line (as well as the phone being apparently uncontactable) so something doesnt seem to good,

Seems overnight that things have corrected themselves.

I now get 650Mbps at the router, and 450Mbps from the PCs... I wonder what caused that, and the reset
