I have a 200 mpbs. In the room and surrounding rooms i get around 100-200 mpbs. However in my room where it is normally around 100 mbps (not even far off from the room of the hub) it goes down to speeds of 30mbps or sometimes just stop working at all. Also, the range isn't great as well, the hub is located in the middle floor, but WiFI speeds are not very well downstairs. I wanted to know if this was just the limits of the WiFi or something wrong with mine. Here is my BQM Graph and my upstream, downstream and network log. The red bit in the BQM is when my device was offline! Thanks in advance:

What speed do you get with a wired connection?  

Given that you are getting up to 200 with a Wi-Fi connection in the same room I'd guess this is a Wi-Fi issue and pretty normal

You can go through various steps to optimise your Wi-Fi including checking with an analyser app, changing channels, separating 2.4GHz and 5GHz and so on.

The cable network and BQM data have little to no bearing on the Wi-Fi performance within the building.

You may get more consistent/better Wi-Fi with a different router or mesh system.

Thank you, may I ask how one can seperate 5ghz and 2.4Ghz? Also, do you recommend a specific analyser app?

Login to the hub and change the Wi-Fi network names (SSID) in advanced settings - put a 5 on the end of 5GHz name and a 2 for 2.4GHz - various details of you to do that on these forums if you have a search.

https://www.virginmedia.com/help/virgin-media-configure-advanced-settings-on-your-hub

You can then easily see which your devices are selecting.    5GHz gives better speed but over a shorter range.

Any of the free apps depending on what device/operating system you are using.  Look in the app store - See which works best for you.

For iPhones you can use the Apple Airport Utility and enable Wi-Fi scan in phone 'settings' (turn off in settings after use to save battery).  Android phones/tablets have a choice of some great free apps with graphs etc.

inSSIDer, Acrylic or Netspot are all good for Windows.  Netspot for Macbooks.

Also, bear in mind that Wi-Fi is deliberately designed not to go too far. The authorities impose a power limit (100mW I recall) for a reason - otherwise some might be antisocial and hog all the Wi-Fi bandwidth in their neighbourhood, without regard for others.

No single router/access point is going to cover all the floors of a building at consistent high speeds.

I'm currently using a D-Link router which offers good Wi-Fi performance and provides over 200mbit/s downstairs near the router (much faster for LAN connections, from my NAS etc.) but slower elsewhere in the house including upstairs - as low as about 10 mbit/s in the bathroom for example.  Hence I use a BT Smart Hub 2, connected via Ethernet cable, as an additional wireless access point and Ethernet switch providing good speeds and connectivity upstairs.  

If you need to cover a whole house/building with fast speed use multiple APs or a mesh system.

Planning to get a powerline, will that make it better? And is it better than normal wifi extenders?

Either can be a problem, best to get a good quality Wireless Access Point.
