Hi it seems im in the same situation with a 3810 as a few others. The tv cuts out very regularly sometimes doesn't work at all. Often I get messages saying missing advanced wireless receiver but more often error codes. The router is less than 3 m away and signal is normally excellent when its working.
Is there any help anyone can offer to solve the problem. System restarts and checking connection are not providing a long term solution. Thanks
This just became a problem for me today as well . TV cuts out constantly with a message "Missing Advanced Wireless Receiver" .
@cnash @Timderwen The wireless receiver is the bump in the power cord and has been unavailable for quite some time now. The power cord for the newer Streaming Stick 4k will not work for your devices. It would appear there is no way of fixing the problem unless you can find a working cord on ebay or something.
