Hi all,
Thought i would share this as i too have been getting all kind of error codes, mainly Error code: [2-0x00000049] - (Could not join or invite friends)
After trying port forwarding and pretty much all other things found on the internet nothing worked until i tried the following.
Some info on my side:
Location: UK
Internet Provider: Virgin Media
Router: Superhub v2 (AC)
Package: 100mb
1 x Xbox wired directly to router (Living room)
1 x Xbox wired via Develo Dlan powerline adaptor (Bedroom 1)
1 x Xbox wired via Develo Dlan powerline adaptor (Bedroom 2)
Here is what i done:
First thing i done was reset my router to factory settings by doing the following:
Go into your router settings, i went here and followed the instructions of how to enter my router:
https://help.virginmedia.com/system/...TICLE_ID=27548
Once in i went into superhub settings and at the bottom there is a restore to factory default button, press it and sign out of your router.
Power down the router by turning it off and then removing the power cable and leave for 30 seconds and then power it back up
Wait for all lights to be back up and then follow the rest of my steps.
1: Turn Xbox on and go to power & start-up setting (via settings) and open it up and change it to: ENERGY SAVING MODE
2: Once the above is done i held down the power button for five seconds to power down the Xbox
3: Once powered down i took the power supply cable out of the Xbox for 30 seconds and re-plugged it back in
I then followed this video:

It helped me, i now have fantastic connection and not a single error for 4 days now.
Hope it helps you too.
