Constant "connection time-outs"

I'm getting real tired of the constant "Connection to server timed out" error and/or the "this profile is not permitted to play online"

It happens regularly (but not every time) under these scenarios:

• on first load of the game
• if i return to lobby (exit after a game)
• 30-40min of game play....(see additional comment below)

this last one is my biggest bugbear and the reason I've given up on ranked. During a game, i suddenly notice everyone and everything freeze, yet my FOV is still moving - ie, i can move the mouse and the character will look around but has frozen. I cannot shoot or anything. I notice in the top right of the screen that both the NETWORK and the LATENCY icons are active. My ping appears normal but all is frozen. After about 10-15s I get the dreaded "connect...timed out" error . Clicking continue takes me to another error screen (can't remember the msg) and clicked OK on this screen, puts be back into the game - with a bit of luck I hadn't been killed and can continue the game. Very annoying and counterproductive when playing ranked. Some days if happens every other game, some days maybe once for the day.

I've tried all the suggested fixes from complete reinstall, verification of files, running as admin, and setting the DNS. I'm at a loss.

Last comment was that this happened AFTER I switched to fiber NBN. I went from a 50mbps wired connection to a 500mbps fiber one. You'd think I'd see massive improvement but it's actually worse. NBN keep dismissing my complaint as game related. EA technical keep referring me to FAQs and other links which are of no help

I'm not familiar with Wireshark, but can something like that help identify what's causing the drop outs?
