A month or so back, I upgraded (was offered a deal, otherwise I wouldnt have as I was very happy with that service) from the 200mb service (where every speed test I ever did showed at least 150mb, most days I was hitting the 200mb+ speeds) to the Gig1 package.
According to Samknows\realspeed, the speed to the router had been bouncing between 200 - 700, generally averaging below 500. I posted on here and a mod arranged an engineer. The engineer came out, said there was dirt on the fibre optic line on the docsis 3.1 side, cleaned it and replaced a fibre cable at the box to my house. After he left, it was still bouncing around, he came back and swapped the router.
Since the hub swap, realspeed tests show a gig to the router consistently, but I'm getting nowhere near that on any device.
The engineer also patronisingly told me that "People get the gig service and expect gigabit speeds, it's more about bandwidth than it is about speed." I get the additional bandwidth explanation, but have seen people on this package get speed tests showing 700+, I've also seen people with the same problem that I have speeds peaking around 300 - 400, but mostly under 100. I don't expect to get slower speeds to my devices at all.
Today for example, speed tests to a wired gig capable laptop show 50mb. Some days I get up to 400 odd mbps, I've never gone higher than 500.
Prior to this I was getting the full speed to my devices that my package was supposed to provide. Those same devices that were reporting 200+ are now reporting 50mb, 150mb, 10 mb..... I have a smart TV using a cat 6 ethernet cable that on my previous package and superhub 3 never had any problems, now, I find it buffering Netflix, Disney+ or Prime Video a lot.
I'm at a loss as to what to do. I haven't yet put this router in modem mode and disconnected everything to do a proper speed test, I will do and if it shows the same poor speeds, I might log a ticket, but then I will just get the usual "Well, you're getting 1000 to the router so it must be your device can only handle 10mb".
As I stated, on my previous m200 package, I was consistently getting 200, that was even using Ethernet over power adapters, which i have since removed as they were getting pitiful speeds.
I really regret upgrading to this package, but I'm past the 14 day cooling off period.
