T3200M Network crashing when downloading, streaming or playing online

[NuMotiv]

Hey everyone. As of yesterday whenever I stress my internet connection (browsing the web is fine) my network will drop entirely (tv included) for around 30 seconds and then reconnect. I tried a 3rd party router in port one bridged and the issue is still occurring. Because the tv picture has also dropped I assume the issue is with the optik connection. 

Does anyone have any ideas on how I could fix this or what the real reason it could be crashing is?

Same, last night or night before my download speed would go really slow have fibre since august 24th and the tv would stop for like 3 secs and keep going but would do it while streaming Netflix watching the other guys not even in 4K
