Boondog

Bit late, but I have a related problem. Also recently got FTTH fibre 500/50 from Vodafone Ireland, with the same router THG3000 (a.k.a. Gigabox). First thing I did was throw out that Gigabox router, as it cannot split wifi/SSID into 2.4GHz and 5GHz. And there are plenty of other complaints about that router when you look on the web. Replaced it with an Asus RT-AX86U (rated AX5700) and a 10m Cat7 cable from ONT to a central location in the hall downstairs. I would definitely advise steve-b to replace his router! To show you the difference between those routers, I ran a number of speedtests, using a Lenovo T440p laptop, Windows 7/SP1, Intel AC-7260 wifi card.

The Asus tests were run the same, but a few days later. For some strange reason the testmy.net tests stick out like a sore thumb, as does speedof.me. I ran testmy.net again yesterday as a 12 hour test. Visit https://testmy.net/quickstats/Boondog to query my stats. No idea why these results are so low. Not sure if I have a justified gripe with Vodafone, as (so far) the only problem I have is with a Fire TV Stick 4K Max that buffers when watching BBC iPlayer. That Fire TV Stick runs of the 5GHz wifi. I did not have this buffer-problem before when we only had ~35Mbps internet (from PureTelecom) via copper wire.
