If those ping times to 192.168.1.254 remain the same when the connection speed falls, then the WiFi connection is good. If that is the case, see what the download sync speed is. It might also be possible, in one of the menus on copper-based broadband routers, to see the SNR (signal to noise ratio). I'm guessing it should be somewhere around 20dB on a decent connection. Higher would be excellent. 7 to 10dB would be marginal.

incorrect.
yes all bt hubs will show snr in advanced.
TARGET snr is 6. that is what it should be if your broadband is stable and at max speed. anything higher means the DLM is limiting your speed due to instability, or your speed limited due to contract.

I can't find the SNR value - any idea where it might be?

Can you stick in a Ethernet cable to the router and laptop and see if the issue persists? IMHO it doesn’t sound like a WiFi problem. More of a ping or dns issue.

first off your connection is low and really only viable for one user
your ping is fine as thats the first number 74ms
you need to speedtest at alternate times as well as at different times the speed is effected
bt do throttle the connection at peak times more so in rural areas like yourself so you could also be dropping speed as well sometimes a rebooot of that modem is the better option as it can bring back the speed for you instead of leaving it on forever as what most do
as goes for the bt you could get a different router and dmz through your bt router to the newer router ive known it with bt that a better modem solved your issues that your seeing
turn off mobile wireless try with different devices and speed test through all of them
you can also drop your wireless connection from 5 too 2.4 as that can give you a much better connection
as quoted above noise on the line and its a bt issue and that is known for dropping your internet connection

Got it. Obscured the MAC address in case... of something.
Noise margin slightly indecisive at 26 or 4.3 dB.

Yes, will try an ethernet cable when the fault happens again.
Could try switching to 2.4 GHz only - I can't see my getting any benefit from the 5 GHz channel, given the crappy speed.

he might need a noise attenuator to reduce the noise on the line

My understanding of SNR is the higher the better, so 26 dB with a threshold of 6 dB means good, no?

not how that works

no. forget the 6.3. thats your upload snr. irrelevant.
the target snr for max speed is 6. if it is higher than 6 you have a issue that is causing the speed to be held down to keep the line stable. (in fact this is the reason you shouldn't switch your router off whilst not using it. the dlm doesn't know the difference between a line drop and a intentional power off... so it keeps slowing you down until it stops 'dropping', which as its a human powering it off, never happens...)
if its at 6 but you are below your minimum speed, then your line is noisy due to a fault. if its above 6, dlm is holding your speed down.
that is it. that simple.
