Mmmm.... this is the dilemma.
Gettting your own wireless router, Mesh system and/or wireless access points will certainly sort all your wifi issues out - I did that >20 years ago and have never had a wireless issue in any room in my 3-bed semi.
However, if there is an underlying network connection issue - it wont cure that. And ATM there is no clear evidence either way - although you saying the wired pc "sometimes" drops is a bit concerning.
So you could try testing that continuously to see if they drop at the same time and see what the hub lights do when it occurs - does the wifi light flash and does the base light stay solid "whiteish" or flash green?
You could also follow the protocol below so that any underlying issues should be made apparent.
_________________________________________________________________________
Post up your Hub/network connection details and someone will check to see if there is a problem there. In your browser’s URL box type in
http://192.168.0.1 (or
http://192.168.100.1 - if in modem mode) and hit return. On the first page up [there should be no need to login if you have done so before unless you have the New Hub4 when you do] click on the “router status” icon/text at bottom-middle of first page up and then copy/paste as “Formatted Text” (not images) 3 FULL sets of data onto here – 2 pages from the Downstream, 2 from the Upstream, & the Network Logs page. Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - if you copy/paste the data, the board software will do this for you (you may need to click the "submit" button again.
Also, in the meantime... If you haven’t already, set up a free and secure “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph” (as per instructions on the TB website) when it starts to develop.
