Bad internet connection affecting gaming

[Iggy101]

For roughly two weeks the internet has been rough to deal with - the speed is the same as usual but the router keeps dropping the internet every 30-40 seconds and immediately reconnecting after.
We went and bought a new wire for the connection to flow through which did help when playing games as my latency (ms) went from 7000+ to roughly 1500.
We also tried plugging in the router at the main socket which did actually stop the disconnects but the signal strength was pretty poor (1-2 bars) which made it unbearably slow for other people in the house. However, it only worked because we put pressure on the start of the wire (the bit that's plugged in)
I've tried wired connection - ethernet - and that has no difference from when i used wi-fi.
We've bought new adapters and inserted them into the wall.
The wire that the router is attached to comes straight from the socket to the router which is exactly next to the PC.
Now, i'm wondering if any of you guys(and girls) have any idea on what could be causing the issue? All the wires have been replaced etc.
(not an expert so dont ask too many questions 😛)
IT WAS FINE 2 WEEKS AGO BUT EVER SINCE IT DOESNT WORK PROPERLY

A number of factors can cause your connection coming from your ISP to falter and also produce the issue as you've stated above. One of which is that the source of your internet connection i.e your ISP may be experiencing an issue with their mainframe and subsequently the way they manage their clients. It'd be good if you could contact your ISP and see if the issue can be resolved as the replacement of wires hasn't proved fruitful outside of additional expenditure.

You can furthermore confirm that the issue is at the origination by having your system connected off the LAN port without the router and/or switch acting as a middle man.

Is it possible to pass on your router's make and model number? Could you pin point what took place 2 weeks ago that reduced your internet connectivity? Thunderstorm/lightning?
