Xbox suddenly loses internet connectivity

Hi

My old faithful Xbox360 suddenly lost internet connectivity.

No other device in network has any problems.

Xbox shows up in router device list with correct MAC and is issued a proper IP address.

Xbox is connected to network via a TPlink switch, but as per tests that is not the problem.

Specifics before the onset of outage:

• previous use Xbox required login with password, after this functioned normally. Next time no connection to internet
  
• no changes to hardware in the network
  
• no changes to setting in any device of the network
  
• no change to ISP
  

Tried so far:

• restart router
  
• disconnect router from power for 5 minutes (multiple times in conjunction with the following)
  
• reset router
  
• reset router settings to factory
  
• different cables
  
• both LAN and wifi connection
  
• tried different ports in switch
  
• reset switch
  
• direct connection to router (moved the whole damn Xbox setup next to it)
  
• automatic and manual IP settings (on Xbox)
  
• dynamic and static IP (on router)
  

So basically nothing was changed, and everything I can come up has been tried.

This has happened, and has been solved before (was just as mystical), but I just can't remember how it was solved befor.

Following status report can be pulled on Xbox:
