I cannot sign in on my Xbox One S, keep getting error code 0x80a30204....It has also began to lag very badly during loading and such. Any one else have these issues?

Networking and lag issues

Can you access your router's web-utility interface and change the wireless channel, that your wireless router are currently using. Experiment with the following channels, and let me know if you notice any significant change.

Channel: 1

Channel: 6

Channel: 11

Also for the record: Try the following steps up front, so we can rule them out, as being the culprit.

Delete Xbox LIVE profile safely

Networking and lag issues

*This problem has been going on for about a year now*

We moved in town to a new home. Same ISP, same hardware as our previous home.

My 360S now has a hard time connecting to Live- it usually won't connect the first, second or even third try. Sometimes reconfiguring the network settings help. I've been trying to play co-op with my brother recently, and the lag is terrible.

I tried every trick I could find to sort out the issues with my Apple Airport Extreme, but didn't seem to be having any luck. I finally broke down and purchased a Netgear R7000 router today and I'm still having lag issues.

I am at an absolute loss for what could be causing the problem. (I think I eliminated the router as a problem, since it is recurring on two separate pieces of hardware, and distance from the router should not be a problem because the base station
is directly above the console and separated by maybe 8 feet)

Is it possible the console is the culprit here?

Any ideas?
