A long bit of context: So we were on the Virgin M350 plan, but due to the abysmal coverage and speeds, I purchased a TP Link Archer AX1500 and TP Link RE700X Extender. I ran the Hub 3 on Modem mode with the AX1500 as main router. It definitely improved our network significantly but still had quite a few issues. I would get over 300Mbs upstairs in my room - however I would sometimes get unstable ping - perhaps due to the extender. In a few rooms, we would get some disconnects and poor speeds (less than 50mbs).
We are now on the Gig1 Plan. I am now using the Virgin Hub 5 with their black WiFi Pod (can get 2 more if needed). I do feel WiFi has generally improved around the house, although quite a few rooms get just less that 100mbs. Upstairs in my room, I now get around 420mbs but my ping seems more stable (with some spikes).
I realistically can't run long Ethernet cables around the house.
I used to separate the 2.4 and 5ghz in our old setup. Annoyingly, I have to keep them together now in order to use the Virgin WiFi Pod.
Is it possible with my current hardware to improve our network? I have my previous router to spare and can get up to 2 more Virgin Pods.
