I must second this. Use a cable. I use a cable whenever anything requiring snappy live connections is in use. Wireless doesn't cut it, especially when your voice chatting or even livestreaming at the same time. You can't expect a wireless connection not to flake out in live sessions, it's that simple.
Eh, while this is just good advice I'd always advocate anyway, it's not really productive here, since this problem isn't with wireless signal.
It happens equally often on wired as wireless connections, and if I get connection errors on one type of connection, router, or ISP, they are still there if I try another.
My home connection has always been wired because my building's internal walls are impenetrable to wireless signals, so I'll sing the praises of wired connections 'til the cows come home. But when these errors happen they do not discriminate between wired and wireless. They just persist for a while, wherever you attempt to log in from on whichever connection type, and then eventually go away.
The folks who have experienced them from MTU issues of course, fixed them with something simple which again, has nothing to do with being wired or wireless. The people who fixed them by deleting their xbox saved data, again, nothing to do with connection type.
Good practice is good practice, but unhelpful to this specific issue.
The last couple of days though it seems to not have been quite as bad as earlier in the week. So whatever is causing it may have cleared up, at least for a while. Mostly back then it would be several hour outages of up to half a day or more. Lately I can usually load to my cockpit from the menu within about an hour.
Though I no doubt jinxed it by saying so.
As an aside....
Wireless is a stop-gap for emergencies and getting something faster and cheaper than your 4G data plan when on your phone or tablet at Starbucks.
I dunno, my 4g unlimited data plan is pretty handy. It's what I use as a backup when my regular connection at home goes down because some construction ended up cleaving a fibre optic trunk nearby
(Literally happened three or four times in the last 20 years, what you get for living near the city centre I guess - you can always tell it's happened if you're out in town bc every store only takes cash for a couple of days) or more commonly, when something more mundane causes an outage. Which is like, once a month. Sure, it only downloads things like patches for my xbox games at around 45, around half of what I'd get on my home connection, but it's good enough for streaming netflix in1080p on my xbox and playing games
(I even tether it to my laptop to play games like Warframe and the like when travelling on long train journeys).
