Wi-Fi keeps disconnecting

[Pablo+872]

Not sure if it's an update that has caused the issue but since Wednesday my Wi-Fi keeps dropping out after about 20 mins. I've reset the glass and the router. No issues with any other devices.  Can't watch anything as it's happening constantly. Had so many issues when we got the tv on Nov21 but recently it's been a little more stable. Until this week? Anyone have anything similar? Could it be the Wi-Fi card?

@Pablo+872 Just a thought, have a look in Settings > System Management and make sure Networked Standby Mode is switched on.  When I first got Glass my network kept dropping off (not as badly as you though) and I found this resolved the issue.
